2.7X PRXDecrypter Released!

Firmware 2.7 Decrypted!

Dark_Alex has released yet another breakthrough in the quest of PSP firmware supremacy! He has just released his 2.7X PRXDecrypter application, which does exactly what it sounds like. It can decrypt PSP firmwares that previously couldn't be decrypted such as 2.7. Dark_Alex has only tested it on 2.71m, but the test came out successful, so you can bet on it working for firmwares 2.6 and 2.70.

Just like Dark_Alex's other programs 2 PSPs are needed, a 1.5 PSP and a PSP running firmware 2.6. Here's the instructions on how to use it:

1.50 part

Copy __SCE__psar_dump2 and %__SCE__psar_dump2 to /PSP/GAME/ in the memory stick.
Get the DATA.PSAR of the EBOOT.PBP of the update you want to decrypt (2.71 for example) and put it in the root of your memory stick
Start the program.

This is simply a psardump (PSpPet) mod that will dump the firmware ENCRYPTED to /F0 and with the correct paths.

2.60 part

Be sure you have the F0 folder with the ENCRYPTED dump obtained in the 1.50 part.
Copy prxdecrypt27X to /PSP/GAME/ and start the program with the eLoader.
The memory stick will flash for some time. When it finishes to flash, restart the PSP.

You'll now have the decrypted firmware in a new created folder: /FD

So, what does this mean for homebrew? Well, it could lead to an exploit being found in firmware 2.7 if there is one present. I am in no way saying that there is one or this will lead to homebrew on 2.7 so please do not jump to conclusions. It could also lead to 1.5 users being able to launch firmwares 2.6 and 2.7/2.71 on DevHook; so stay tuned to PSPupdates!

Good news! Man I hope this leads to a downgrader for 2.71 or at least a way to run homebrew on it. If it does I swear I'll never upgrade my firmware again, I'll just buy another PSP for things that need the newest firmware.

Great job guys keep it up! Sooner or later 2.71 will be downgradable I can feel it.

# w00t — Guest 2006-07-07 04:06

Man, i'm so happy!

# hellz yea! — Guest 2006-07-07 04:08

hopefully devhock will be able to emulate this soon!

# Coolness — Guest 2006-07-07 04:09

I hope this works with dev hook soon

and then leads to running kernal mode homebrew on 2.7x

(Correct me if im wrong but I thought the eloader didnt work on 2.7)

# Great job! — Guest 2006-07-07 04:09

Well, Done! knew this would happen

# WOW — Guest 2006-07-07 04:11

WOW!! is there any stopping this guy, with kernal access here, downgraders there, HE RULES!!! i upgraded to 2.71 as i like keeping up to date on stuff (sad, i know but thts me) and if i can have the possibility of homebrew it can give me extra things to do inbetween ACTUAL games

well done Dark Alex

# 2.7/2.71 .... — Guest 2006-07-07 04:11

I know this doesn't in any way guarantee it, but I hope this leads to a 2.7 exploit being found. Still coming to the terms with the fact that I upgraded to 2.7 a day before the 2.6 kernel explot was found :(

just my luck I spose!

loving everybody's work at the moment in blowing 2.5/2.6 wide open.

# @12 — Guest 2006-07-07 04:12

This can decrypt firmware 2.71 on a 1.5 and 2.6 PSP. You cannot run homebrew on 2.7+

# Can I get an amen.....? — Guest 2006-07-07 04:12

I just wanna say that the last couple of days has been crazy in PSP land! I love these kind of days! LOL!

You keep on going Dark_Alex! RESPECT!!!!!!

Do I hear an Amen....? lol

# Oops — Guest 2006-07-07 04:14

Thanks Kyle. M

I slightly misread the post

Still a great achievement

# Julys News — Guest 2006-07-07 04:14

Last few weeks have proved to be very interesting for PSP owners. It is such a shame that there are no good games being released..

# 2.71? — Guest 2006-07-07 04:15

What about 2.71? will this work with 2.71?

This cant brick your psp can it?

# truely — Guest 2006-07-07 04:19

really.. i need to say, it's great work... but i hope oneday u can find a way to get to 3.0 (when it's out) just like 2.5 or 2.7... 3.0 (with PSone Emu and lots of goodies) will be a hard choice to 1.5 user for upgrading or not...

THAT MEANS THAT BY THE TIME NCAA FOOTBALL COMES OUT ILL BE ABLE TO PLAY IT ON MY 1.5

# What??! :D:D Great news!!! — Guest 2006-07-07 04:27

Dark_Alex, your da man!!!

Now with firmware 2.7x decripted I hope 1.5 users may load it with devhook and maybe this will lead to find an exploit in 2.7x firmwares

THAT! Would be good... I think you can do it! I'm most sure is not impossible to find a exploit in 2.7x.....

If you could do such thing...you will be a TRUE LEGEND, for history! Say amen to Darl_Alex!!!

# Man shut the ***** up — CBMaster 2006-07-07 04:28

Man Im tired of this person with his releases thinking hes a cool coder in such. You might all know me as the kid in the video I posted, but hey, at least I know more coding than them.

Sure, go against me, but I'll make a petition that goes against his work, cuz as much as he helps, he also destroys....

# i need instructions — Guest 2006-07-07 04:30

i have a 1.50 psp and my cousin has a 2.6 would that mean i have to get the data psar from the eboot in the 2.60 update please respond

# @CBMaster — Guest 2006-07-07 04:32

Well, If you've bricked your PSP it's your fault. There were warnings, don't whine about it.

I feel sympathy for those tha brick their PSPs, but those that moan and blame the developers afterwards: Tough Luck.

# No #24 — Guest 2006-07-07 04:33

No #24 don't ***** - if you can do better, let's see it!

Great work O Dark one.

# @CBMaster — The 69th Floor 2006-07-07 04:35

How can you say that? If you bricked your PSP, 2 bad, but don't blame it on him!

Get yourself a mod chip and unbrick your PSP!

And please, just stop whining will ya?!

# how? — CoBrA2168 2006-07-07 04:37

How can i get this to work with devhook? or are we not that far yet

# @No. 19 — FLai 2006-07-07 04:38

Eh, I beg to differ. Tekken and Gurumin were released only 2 days ago.

# nothing can stop dark_alex — Guest 2006-07-07 04:38

he is fast, he is one of the bests that i saw, dark_alex go on, do it man, you can more then this, we believe in you, you are a person that deserves respect from all the ppl that have psp, you dont make fakes, what you have, you really have, and do it really fast. Tanks man, im waiting your great brain find a 2.7 exploit, i believe in it.

# FIRST POST! — Guest 2006-07-07 04:40

Oh shi-

# Why — Guest 2006-07-07 04:42

Seems like this is to enable developers to examine the firmware closely to find out how it works and how to emulate it or bypass the security.

Therefore why are some of you's that clearly don't have enough of the matter between your ears interested in this?

If you cant figure out how to work it, maybe it's for the best!

Regards

Me

"I know more coding than them" .... What the f***!

Why don't we ever see your name anywhere but on relentless coments that lead to where. All you ever did was to moan at developers who came up with things you CAN'T do.

Or is it because you bricked your PSP trying one of his apps... lol .. WOW what a programmer you are.

Sucka

# to CBMaster — akuma2099 2006-07-07 04:54

Just because you bricked your psp it isn't the devs fault. There were warnings all through out the article and it warned you that it was untested. Just don't use any other piece of homebrew ever again and you will be fine safe in your little protective coccune. Anyway Dark_Alex, much respect for your hard work and generosity to the PSP community. I have not used the downgraders yet but my friend used the 2.5-1.5 one and you brought a whole new world of PSP stuff to him so thanks for that. Also once this is put to use in a new version of devhook then we will have the ultimate PSP a version 1.5 that can do everything that every other firmware can. AH HA HAH!!! World domination through the PSP.

# yeh ... — Guest 2006-07-07 04:55

*****, you are a kid cbmaster, and you suck, your video suck, and you know anything, you know what the most of ppl know, what ewe read on sites, so ***** man, put this in your ass, and do some lessons of video and respect, because you are a great noob, if your father think you are a genius, congratulations , but here you are a noob, dark_alex did more in 2 weeks then you in all your little life, grow up and dont make suck replies like this, now tell to your daddy to buy a new to you, and brick again and put in your ass again noob.

# !!! — Guest 2006-07-07 04:56

dark alex is a beast!!

# An update... — Guest 2006-07-07 04:56

Look at his website: http://dax.psp-tuts.net/

He updated the decrypter:

"PRXDecrypt UPDATE

Now 2.60 reboot.bin gzipped is decompressed.

The problem with it was Sony changing of module the UtilsForKernel library ¬¬

The 2.7X reboot.bin is still not decompressed. It uses a new format of compression (RLZ?), and a new function introduced in 2.7X is the one that do the job:

sceSystemMemory Manager::UtilsF orKernel_7DD072 71

The download is in the same place than the previous one."

# I HAVE A QUESTION- an answer would be appreciated- — xsouthpole 2006-07-07 05:00

This is cool and all, and i take nothing from Dark Alex, very smart guy. But I have a question, that, while it may sound sort of n00by, is accually a good question and would be awesome if my question could eventually be answered with a yes. Ok, here goes....

You remember the PSPE right? For windows. Yeah, that one. Would'nt it be possible to (maybe with slight modification of the programming), run devhook on PSPE, and in turn play psp games on the computer? Because I have the new Devhook, and I can play all my iso's without a problem, and luvin it, but could'nt that be possible if the dev's took a week to look at PSPE compatability for devhook?

# wait wait — yoyomacy 2006-07-07 05:01

ok i thank dark_alex, BUT whe you start something, please finish it, you made a downgrader for 2.6 now conintue on that and nmake a downgrader for 2.6 on a TA-082 MOBO...did ya think of that

# HELP ME!!!!!!! — Guest 2006-07-07 05:01

# to 57 — CoBrA2168 2006-07-07 05:04

i hope hes able to make two versions of devhook one for 1.0 psps and the other for 1.5 psps, that would be really cool. Keep up the great work dark alex.

# This is so awesome — Guest 2006-07-07 05:13

anyways when 2.7 and 2.71 are done with I think you should all go back to 1.51 and 1.52 cause thois firmwares were never cracked , I know that hacking them is unuseful but it would complete the collection of firmwares cracked , anyways keep working on 2.7 and 2.71 , I will downgrade to 1.5 and would like to have the stuff from 2.7 and 2.71 :)

# man — Guest 2006-07-07 05:14

its the once time that i will tell this to you, download winrar at the sites, install it, and extract, so after this you can load this .

# Dark_Alex RULES!!! — Guest 2006-07-07 05:16

It's been said many times before, but I just fealt the need to confirm it. Keep up the good work, dude! It's really quite revolutionary what's been happening to the PSP over the past week.

# yes — Guest 2006-07-07 05:18

soon devhook will be emulating 2.7 because of this!

# Downgrader first — Guest 2006-07-07 05:21

If dArk Alex is reading this work on the downgrader (if possible I know its possible for a genius like you though) first the n Devhook. For the better of the PSP community as a whole.

# Confused — Guest 2006-07-07 05:23

Sorry guys for a newbie question - but my PSP has 2.71 on it - what does this decrypter do??

I'm hoping that it will allow me to eventually downgrade my 2.71 to a 1.5 - am I right??

Thanks in advance.

It would be really nice if we can use the 2.7x firmware with devhook! Just like #69 said, it would be awesome if the new devhook would work on a 1.00 PSP aswell!

Later...

# good job — Guest 2006-07-07 05:26

So does Booster just implement this into his firmware installer program, which sets up the firmware for DevHook to use. So 2.6, 2.7, 2.71 firmware emualtion is almost upon us?

the PSP scene is firing on all cylinders now. keep up the great work guys! unfortunately everyone seems so focused on escaping the newer firmwares when they should focus all of their energy on breaking those instead. imagine kernel mode on 2.71 the whole community could upgrade to! think cake and eat it too.

# reboot.bin — Guest 2006-07-07 07:02

DARK_ALEX HAS JUST WORKED OUT HOW TO DECOMPRESS THE REBOOT.BIN WHICH IS THE ONLY THING THAT WAS STOPPING THESE DECRYPTED FILES WORING WITH DEVHOOK!!! HE SUSSED OUT THE DECOMPRESSION METHOD AND THE NEW PSXDECRYPT ALSO DECOMPRESSES THE REBOOT.BIN, EXPECT A NEW DEVHOOK SOON WITH 2.71 SUPPORT.

# No. — Guest 2006-07-07 07:03

to xsouthpole

No. Absolutely not. NEver. It's completely and totally unrelated. You knokw nothing about what you are talking about, and there is no chance in hell, because you can't just drop in software and expect something like that to work.

An emulator emulates HARDWARE, not software. It doesn't matter what software you throw at it, it won't work unless the hardware itself is emulated accurately enough and fast enough. PSPE does not emulate a memory stick, it does not come even close to 100% accuracy, and trying to load up devhook on it would almost certainly not work, unless the coder of devhook implemented his own PSP emulator inside the code.

And he did not. That would be like asking, "LOL if I load up Top gear 3000 on zsnes will that allow it to emulate the DSP-3 chip?"

But it could be possible in about 8-10 years, literally.

# We Dont Need Exploits We Have 1.5's — Guest 2006-07-07 07:10

WHO CARES ABOUT DOWNGRADING,

I say this because people who did upgrade knew they were losing homebrew.

For the people have 1.5's engoy the flash player, if we have devhook what would be the point to even upgrade. For poeple who have there PSP's to friends and they upgraded it, it's your fault not your friends.

NOW FOR, US THE PEOPLE WITH 1.5 ENJOY THE UPCOMING FLASH PLAYER

# @128 — Guest 2006-07-07 07:15

I'm more interested in getting games higher than 2.60 working on the PSP. I'd put the flash player second since the gaming is what's more important ;).

# 2.71 ON DEVHOOK — Guest 2006-07-07 07:24

TO UPDATE YOU ON POST 125, MY MISTAKE HE HAS ACTUALLY CRACKED THE DECOMPRESSION METHOD FOR 2.60 REBOOT.BIN FILE, BUT IT LOOKS LIKE FLUFF IS ON THE CASE AND HAS SEEMS TO HAVE WORKED OUT THAT THE REBOOT.BIN IS ACTUALLY ENCRYPTED TWICE, SEE COMMENT FROM FLUFF BELOW (TAKEN FROM DARK ALEX'S SITE)

PRXDecrypt UPDATE

Now 2.60 reboot.bin gzipped is decompressed.

The problem with it was Sony changing of module the UtilsForKernel library ¬¬

The 2.7X reboot.bin is still not decompressed. It uses a new format of compression (RLZ?), and a new function introduced in 2.7X is the one that do the job:

sceSystemMemory Manager::UtilsF orKernel_7DD072 71

The download is in the same place than the previous one.

damn i hope we can decrypt 2.7 completely :(by Fou-Ryu @ 07 Jul 2006 04:22 pm

Hm... RLZ?

Never heard of that... o.o...

Anyway - Good Job once again...

That means that ATLEAST 2.6 can be emulated on devhook soon...

About 2.71... I hope that it soon will be cracked aswell...

You said he has he new reboot.bin any ideas where to d/l it at bc im working on devhook and changed all the files over to 2.71 i just nee d the reboot.bin so i can reboot it off of flash.

# wow!! — Guest 2006-07-07 07:44

An amazing string of once thought impossible feats! Keep it up Dark_Alex!!!!!! !!!!! I cant wait for the new DevHook!

# to 135 — Guest 2006-07-07 07:46

I made a mistake, the reboot.bin from 2.6 has been decompressed, fluff and dark_alex are working on decompressing the 2.7 reboot.bin right now, it wont be long he already cracked 2.7 encryption and the decompression methods for the 2.6 reboot.bin all today, I would be suprised if he does it today.

I already compiled the 2.71 firmware for devhook and tried the decompressed bin from 2.6 - NO GO. we definatley need the decompressed 2.7 reboot.bin, but even then you will need to alter all of the txt files in the vsh and kd directories and add entries for the extra prx's (i.e usbgprsr.prx, usbmic.prx and usbcam.prx)

I think booster will need to alter devhook to to tell it where to lead the devhoo.prx in the 2.71 firmware...etc. Shoudl be difficult for him to do as soon as dark_alex and fluff bust open that reboot.bin.

# wow — Guest 2006-07-07 07:46

yeah!!!!! i love you. keep working on it

# With the PRX files the current Dev Hook can't emulate 2.6 — Guest 2006-07-07 07:47

I just tried and replaced all the files of 2.6 including the reboot.bin and it would get the the sony entertainment default psp bootup then just die. So its a no go atm but its very possible for it to work since i got it to use the reboot.bin and reboot but either the 2.6 files i d/led where corrupt ofr the emulator can't run for whatever reason. I just hope booster can get this going once the reboot.bin is done for 2.71.

# Automatic Upgrading — Guest 2006-07-07 07:52

I really doubt sony would do automatic upgrading because they already take the precaution of checking for the AC adaptor before upgrading. If they took that away, then I'm sure many psps would be bricked as the battery died during the update. I'm just saying it's not a very practical idea.

# to Oriyen :hmmm, interesting — Guest 2006-07-07 07:53

interesting, at least its getting to the sonytscreen so reboot.bin is doing its job, I didn't think to try the decrypted 2.6's with devhook!

SOMETHING FOR YOU TO TRY::are there some extra prx files in 2.6 that aren't present in 2.5, if so you will need to add entries for them in the following files:

dh\250\flash0\k d\pspbtcnf.txt

dh\250\flash0\k d\pspbtcnf_game .txt

dh\250\flash0\k d\pspbtcnf_upda ter.txt

dh\250\flash0\k d\pspcnf_tbl.txt

There may be a few other place to add them too, I am going to ahve a play around in the meantime. Le tme know how you get on

# @138 — Guest 2006-07-07 07:55

You said the .txt needs to point to the new prx's correct as well as added strings so do u mean the files located in the \dh\250\flash0\ dic area or do u know if they can get new registry files for 2.71 bc we are trying to run 2.6 with 25 registry files tahts located in \dh\250\flash1\registry bc the flash1 250 is still being used. Or are we gonna just have to wait for Booster to redo devhook.prx for the new firmware?

# @!43 — Guest 2006-07-07 08:01

no just need to add any extra prx files, the text files are the lsit of prx's devhook needs to load, if one of the new 2.6 prx's relies on a new prx that isn't loaded, OS wont boot. In regard to reg files, I dont think that matters as if they dont work the firmware will simply display a corrupt settings screen and should re write the regsitry files for 2.71. Got a big feeling that devhook.prx probably gets load at a different entry point, who knows its all worth a try, I'm sure we'll see a new version of devhook for 2.6 ( and maybe 2.7 ) in the next few days (or hours) just need to crack the decompresssion ( and possibly encryption as fluff mentions) on the 2.71 reboot.bin and we are away!

# Found some stuff between 2.5 and 2.6 — Guest 2006-07-07 08:09

k in 2.5 there are 2 files that are no longer in 2.6

uart4.prx

utils.prx

and the only new file in 2.60 is

pspnet_adhoc_di scover.prx

so im going to remove the two then add the other one to all the .txt files ill let you know in aminute what i get.

It decrypts the 2.71 firmware so you can extract the psar out of it (the psar contains the firmware basically), think im right but i havent slept for 2 days!

# Wow... — Guest 2006-07-07 08:25

You never cease to amaze me, Dark_Alex. As if the 2.6 and 1.5 downgraders weren't enough, now this? What next?

Of course, this doesn't necessarily mean there -will- be homebrew availability on 2.7+, but we've now got a much better chance at finding something that'll allow it.

Oh, and this may be a bit premature, but there's two simple words that express how I feel towards them right now: GAME. OVER ;)

# AWESOME NEWS!!!!! — Guest 2006-07-07 08:50

I was able to run 2.6 Monster Hunter Freedom US Version UMD with dev hook. I took the flash0 dump i got from the PSAR Dumper replaced all the files in there spots, then took all the new 2.6 .prx files and transfered them over deleted the two unneeded files mentioned above as well as added the new file to the 4 .txt files started devhook the memory light blinkin for a few seconds then stopped and nothing happend i was like crap didn't work but i heard the umd drive spinning and reading and about 1 minute later Monster Hunter started loading off the UMD. I then tried to go back but the minute i pressed the homekey it froze up so taht means the problem atm is devhook.prx neeeds to be updated. Or sumthing but hey it just shows its now possible.

# oh the joys of july — aguycalleddave 2006-07-07 09:26

Horaay! if you can extract prx's then there must be some tiny form of exploit. This could be used to make a 2.70 / 2.71 to 1.5 downgrader! horaay!

# ok 172. — Illegal Machine 2006-07-07 09:29

then what happens when nintendo wants to release their PAY service where users would download NES, SNES, and N64 roms for 5 bucks a piece?

Should Nintendo suffer loss in SALES on wii consoles, AND GBA sales, AND GBA game sales, AND DSL sales. AND the revenue they would otherwise collect for rom downloads?

Maybe they should just close thier doors, and sell thier assets off to sony and microsoft, because SONY could just run ads that advertise Nintendo wares all day long.

Just to increase your purchase incentive.

# Sony can't... — Guest 2006-07-07 09:37

I dont think that Sony is entirely anti-homebrew. Just think about it. If Sony released a firmware update that supported homebrew they would be swamped with bricked PSP that they would be responsible to repair because their firmware allows homebrew. Look at how many noods brick their PSP's, now picture this on a massive scale. As far as Sony advertising emus...just think about how many lawsuits they'd be hit with. Sony doesnt own the rights to any Nes, Atari, C64...etc titles. How could they advertise about something they dont own? At the end of the day, Sony isnt in business to do people favours or be nice to homebrewers. When a firmware gets cracked Sony has to upgrade it because the game publishers arent going to keep making games for the PSP if theyre not selling...no games, no PSP. Sony has to do what they have to do.

P.S. Great work Dark_Alex!!

# yea — Guest 2006-07-07 10:00

# @ 175.. — Dragoon 2006-07-07 10:10

Are you retarded? Sony wouldn't advertise the emulators, that'd be stupid. Sony could, however, mention that emulators have been developed by others and work on the PSP. Sony could also state that 'Using homebrew can be potentially dangerous and we can not be held responsible if you fudge up your PSP.'

GOOD GOING DARK_ALEX!!!!!! !!!!!!!!!!!! correct me if im wrong but didn't he also make the daxziso? the legendary stuff? but yeah.. he rock!!! i bet hes got some sort of secret exploit he found, thats why hes doing all these with TWO psps, but anyways as long as SOMEONE can do it, im happy!!!!!!!!!

# H — Guest 2006-07-07 16:57

MAN Dark_Alex is doing everything he has marked his spot in Psp Homebrew history Daxiso, downgraders, 2.7 Exploit it just gets better and better hes on a role he puts other Developers to shame with this many apps, cant wait until the new Devhook and N64 FULL SPEED!! WOOT!!

# 207 — lansingone 2006-07-07 17:07

but if thay do get it patched we will need to wait atleast 2 months for 3.0 to get hacked, and it may be like 2.1 and up that can,t run all hombrew and isin't as easy as just selecting the hombrew from the XMB. if thay don't get it patched then we may only have to wait 4 days for 3.0 to work with devhook. but i know what you meen i have been waiting to play daxter since it was released

# Emulation.. — Guest 2006-07-07 17:24

In responce to 205, no, it is not possible. The clock speed of the PSP is nowhere near high enough to emulate it. Putting aside the back that the PSP runs at 333, and that you'd need at least triple the power to even begin to emulate the proc, and that would be very *****tily. The only way you could do emulation for something almost as powerful would be through identical platforms, and none of those have it.

PS2 - I believe 300Mhz. Far different proc class.

PS1 - Although a different proc class, its weak enough to emulate

GC - Far higher than 333. Outta the question. Same for xbox.

N64 - Weak, and has a MIPS proc. Easier to emulate.

I hope this answers your question.

# Thank You — PSPMASTERBLASTERSTFU 2006-07-07 18:49

Finally someone has 2.7x decrypted. I hope i'm not being way too optimistic, but with that decrypted, can't people see what's exactly in 2.7x and figure out a way around it. And because kernel mode was unlocked after the 2.7/2.71 update, doesn't that mean sony didn't patch the kernel exploit? Meaning if DarkAlex can find a way to load homebrew, he can find a way to use kernel, AKA Downgrader??? I'm so damn happy, cause now we have a working GBA emu, I can scrap my SP, all my games, and buy some new stuff cause i'll have it all on my PSP.

Thank God for Dark Alex

You are the greatest.

# only one psp — Guest 2006-07-07 20:14

hello, guys, I have only 1 psp so can you put a link with the decrypted 2.70 or 2.60 files??

thanks^^

# uhm.... — Sackavelli 2006-07-07 21:10

All due respect to the programmers and coders, but arent you kinda screwing the pooch by releasing all these releases one after another, shouldnt you wait and let sony make the same firmware mistakes over again? Wont $ony just use the progs you guys release to find the holes in their software and patch it up with their next firmware release ? As it is 3.0 isn't finished, and sony hires people to monitor these and dev's sites to wait for the populous to break their coding, then they just fix the exploit

On the other hand, I thought my shlt didn't stink when I had my 2.0 with eLoader, but now I downgraded my 2.0 to a 1.5 (the downgraders been out forever, but the fear of bricking my psp wouldn't let me dowgrade) and do not miss the hit or miss running of apps under eloader (no diss to fanjita or ditlew). Now I know why 1.5 users were elitist turd burglars. Kernal access really is the way....

no jonathan no one can send you the folders for a 2.7 psp because they decrypted 2.71 and yuo cant get an easy version of setting it up on your 2.7 psp because its not for 2.7 all it is is a firmware decrypted which basically means they took the 2.7 operating system and made it readable for coders and hackers hope that helped explain this for you

Actually Xbox runs a 733mhz, but hey, just saying. There is no possible way that xbox or gc could ever be emulated on the psp. Now what would be sweet is psp emulation on the xbox ;)

# ... — Guest 2006-07-08 06:38

Maybe I missed something, but from what I can tell.. this allows 1.5 users to have the perks of 2.7 through devhook, without upgrading. My question is...exactly how does this help 2.7 users?

# ... — Guest 2006-07-08 07:40

-236-

It doesn't, they can't downgrade either so they're screw.

# help — Guest 2006-07-08 07:43

how exactly di i put these files on my psp

# bah — h37 2006-07-08 07:55

It doesn't help 2.7 users... all the 2.7 users in here (tons) that think this is directed at them are getting up false hope... This benefits those who can run and effectively use devhook (1.5 users).

All this means for now is that 1.5 users could use the features of 2.7x firmware without upgrading. That's all. Nothing else. Damn, all these ill thought questions. If you read the original post, it isn't hard to understand what it's about. Seriously.

# I don't think so — Guest 2006-07-08 09:59

I don't think you could emulate a DS because they use dual screen and touch screen for games which the psp doesn't have.

# uh, yeah it does — Guest 2006-07-08 10:34

>>239

How can you say that, once the firmware is FULLY decrypted, it will allow devs to explore through the new functions and look for another exploit to enable downgrades, AND the possibilities of using devhook with the decrypted firmware are obvious as you stated.

# Full Decryption Done — Guest 2006-07-08 10:41

Dark_AleX has announced that he's been able to decompress the reboot.bin so that means you'll actually be able to emulate 2.71 fw on future devhooks

# 2 > borgamix — Sackavelli 2006-07-08 19:17

You stupid c*cks*cker, go purchase a vocabulary so you could understand 1/10 of what I typed. To all you ignorant bastards like borgamix who can't understand the concept of timed releases, all I'm saying is when you let sony release another firmware, you let them repeat some security holes in their firmwares because they dont know of them yet.

"dotn u see the best things is to release everyting quick so that people acn have fun.... " ...priceless

By releasing things so that people "acn" have fun, we're letting sony know the exploits to soon, and eventually, a firmware will be released that will be hack proof.

# from BOOSTER... — Guest 2006-07-08 22:24

BOOSTER is working on a new version of devhook which will support 2.6 ONLY. 2.71 emulation is on its way but the 2.6 version had already been almost completed before Dark_Al' managed to decompress the 2.71 reboot.bin file. Expect a devhook 0.43 with 2.6 support soon, and then devhook 0.44 with 2.7 support a week or so later. He also asked for people to stop uploading the decrypted 2.6/2.7 fw's to pspsoftware otherwise it will get shut down, he has all he needs to finish the 2.6/7 support. thanks.

# to #251 — Guest 2006-07-08 22:32

# Wow! — Guest 2006-07-09 06:18

245. >> WOW! You have a 27.1!?!?!?!? Teh haxx0rz!!!

No, just kidding. But also at 245 this doesnt lead to 2.7 or 2.71 downgrader, devs need to find an exploit that will let them access the kernal...

I will NEVER upgrade my PSP again! The day I figured its gonna be a loooonnnggg while before devs find a way to access the kernal on 2.6 was the day before they did....

That has happened to me so many times, that ive never run homebrew on my PSP...

But i'm lucky that my friend has a 1.5 psp, and he lets me use it for a month or so every once in a while...

Dark_Alex, great job, and keep it up!!!

Does this mean the E-loader will be able to function on 2.71 cos i really regret updating my PSP this time

# to #260 — Guest 2006-07-09 10:52

no, and yes, we will now be able to use devhook to reboot to 2.6/71 fimware, and this also opens up the possibility of us being able to examine the newly decryted firmware and find possible flaws in it to use for a downgrader this securit hole may also open up the possibility to run homebrew on 2.7 but dev's will primarily focus on finding the security holes for a downgrader rather than running brew. Because if you can downgrade you can run brew anyway.

Ya know, I would really love for this to be him, but it's just too damn easy to post as someone on these comment boards.

If it were DA. he should/would just post the news on his site, and he would be flooded with volunteers. Sorry to be a skeptic, but its the way the government made me ;)

# O.O Crazy — Guest 2006-08-07 20:41

For quite some time I just left my PSP sit because there isn't really anything to play, then I recently found out you can play ROMs on it and I was excited to be able to play them hand-held. I searched around for how, and soon found out the only way to play them is have 1.5 and GTA or w/e and that ruined everything since I have 2.71, don't want to downgrade, and won't waste 40$ buying GTA just from some ROMs.

I googled this site and noticed that 2.7x might be the new exploited firmware which would pwn. I'd finally be able to ROM WORLD-WIDE ZOMG =D. Dark Alex, no need to rush yourself but we all are waiting ^^ Jk.

Hope to see a release soon and keep up the good work.
