Tutorial: How to boot FW 1.5 from your memory stick

Posted Aug 30, 2007 at 5:48PM by QJ Staff Listed in: How-To Tags: Mathieulh, memory stick, Noobz

One thing has led to another. Noobz and Team C+D's Pandora's Battery has opened a lot of doors for the PSP homebrew scene and it would seem that the possibilities are near endless. Flamingwolf from our forums posted a guide to running the golden firmware, 1.5, from the memory stick.

It is possible to boot firmware 1.5 from your memory stick and you'll find this nifty guide very helpful. The guide was originally written by Mathieulh. Need we say more? Here's the post ad verbatim:

Install the pandora firmware to the memory stick using the normal procedure.
Copy the files created on the memory stick somewhere on your computer
save your flash1 registry folder into your memory stick root
Extract 1.50 from a psar using psardumper.

extract it as encrypted and then once more as decrypted (save both dumps)

Copy the encrypted dump folders to the root of the MS, and get pspbtcnf.txt pspbtcnf_game.txt and pspbtcnf_updater.txt from the decrypted dump, and use those to replace the ones from the encrypted dump located at ms0:/kd/
Get the flashemu.prx and lfatfs_patched.prx from the pandora MS files you saved earlier (they are in the kd folder) and copy those into ms0:/kd/
open ms0:/kd/pspbtcnf.txt and ms0:/kd/pspbtcnf_game.txt and ms0:/kd/pspbtcnf_updater.txt files using a text editor and:

change /kd/lfatfs.prx to /kd/lfatfs_patched.prx

add /kd/flashemu.prx right after the /kd/fatmsmod.prx line.

save the files

Done, the 1.50 firmware will boot straight from the MS using the Pandora battery. Of course you may adapt this mod to another firmware such as M33.

Using Mathieulh's guide, you can basically boot any FW from your memory stick/s - that's in theory. If they find out how to do this with other FWs then it would be great for homebrew devs who want to test how their creations fare on different firmwares.

Though for now, we'll heed what Dark_AleX says about booting from the memory stick and custom firmwares. He said, "No CFW will work with this, because their kernel subset would need also a flashemu.prx. This method would only work to boot 1.50 from ms."

Well, let's hope for the best anyway. For more info, feel free to scurry over to the QJ PSP Hacks forums to discuss the tutorial.

this is great!!

# nice — Guest 2007-08-30 12:51

I,m glad you find a way to get attention, seems your mother never did...

# Dear QJIdiot — Guest 2007-08-30 13:07

Had you bothered to continue reading what Mathieulh and Dark_AleX have said about this, ONLY 1.50 WILL WORK.

# yo dude — Guest 2007-08-30 13:38

i dont see anywhere that it says dark alex said only 1.5 wuld work

# Cool — Guest 2007-08-30 13:46

Maybe now future cfws will be moded so you'll be able to sitch between them, like 3.40 OE-A and M33, all by booting it off the mem stick. No more needin to Downgrade. Holy Crap!!! I just thought that if you can modifly firmwares to boot off the mem stick w/ pandora, does this mean if pandora's battery doesnt work with the slim, that we could extract PSP Slim Firmware updates on our mem sticks, and modify to boot off the fat PSP!? That would be awesome!!

# sdf — Guest 2007-08-30 14:00

no u cant...the psp slim has features that make it different from the normal fat psp. so if u try to mix one hardware with another's software, u mite get f***ed.

but hey, i could be wrong. :)

# ... — Guest 2007-08-30 14:06

actually she did seem to find it some how because he's now here.

# .... — Guest 2007-08-30 14:10

$h!t....

I bet Snarg is going to pop up talking $h!t now.

What a weener.

# maybe... — Guest 2007-08-30 14:42

Booting 1.50 off the mem stck on a slim might just crash cuz sony probly changed the PSP's idstorage entirely so it workds differently. u never know

# . — Guest 2007-08-30 14:46

I don't fall for flame bait, but nice try.

# . — Guest 2007-08-30 14:52

I know that DA says that this will only work for 1.5, but his reasoning is because of the difference between 1.5 and CFW's

So would this not work for other official firmwares?

Yes I know you're going to ask why would you want to be on any other official firmware, but remember there are people out there who refuse to flash their PSPs, even now. (Some people like the fact that their PSPs have never been flashed), so if they could boot into 3.5x from the memory stick then they could at least play their favorite new games that they buy without having to upgrade.

Just a thought. But if it's not possible, it's no skin off my back, I have no issues with flashing my PSP.

# Go back to school — Guest 2007-08-30 15:07

Idiot.

They said IN THEORY it could be used with other firmwares, but not yet.

Nowhere did they claim it worked on any other FW yet.

# i dont get it — Guest 2007-08-30 15:27

cant u already go from cfw back to 1.5 so wats big about this i really dont understand

# . — Guest 2007-08-30 15:34

I seem to remember something else that allowed firmwares to be booted off the memory stick... oh yeah! devhook. Jebus, how easily has everyone forgotten one of the greatest programs of it's time?

# Dip Sh1t! — Guest 2007-08-30 15:40

I hope you feel like a real dip sh1t. Not only are you a retard for typing "first", but your not even first. Haha. Repeat after me. I am we todd did.

# . — Guest 2007-08-30 15:43

Right, and who was arguing against that?

Your flame makes no sense. But then maybe that's the whole point.

# well wait. — Guest 2007-08-30 15:54

Could you possibly run the PSP this way, booting 1.5 with the Pandora's memstick trick, then trying to install a custom firmware after that?

Then this hack is ungodly, rather then having to try to brick a psp and install the firmware, insted, You get to DevHook it (Pretty much) and installing a new *firmware over an old one. (*Being the only time you had to mess with the BIOS. Multiple flashings is not something I like.) 1 flash vs 2 flashes (at min.)

# from 3.52? — Guest 2007-08-30 16:36

Can anyone tell me if this would work from the newest official firmware or do I have to get a 1.5 unit to do the battery update (the pandora magick sh*t) and then use that? I just don't want to screw up a perfectly functional unit since I just had to replace my last one after getting stuck @ official 3.11 (I only use it for tunes and Tekken now - stupid Namco anti cheat nonsense)

# . — Guest 2007-08-30 17:30

This still requires an altered battery. So yes you would need a PSP that's already homebrew capable (1.5 or any CFW) in order to alter a battery for use.

# hey — Guest 2007-08-30 18:17

can't this fix bricked psps

# oh yea — Guest 2007-08-30 18:42

i did his mom. actually, he might be my kid. and if he is, he's grounded for being a lame first guy.

# only if — Guest 2007-08-30 20:08

only if you have a hb capable psp to create a pandoras battery, or a friend with one.

# i think — Guest 2007-08-30 20:56

i think he was referring to FreePlays comment?!

maybe not tho

# yes — Guest 2007-08-30 23:05

Pandora's Box/Battery can, but you'll have to check this article for it: http://pspupdates.qj.net/Noobz-C-D-release-Pandora-s-Battery-unbricker-for-all-PSPs/pg/49/aid/100579

Uhm... you don't have to "brick" your psp to downgrade it with the *normal* Pandora process.

# nope — Guest 2007-08-31 03:23

$ony wouldn't risk it. It's probably auto-detecting.

# . — Guest 2007-08-31 03:55

"Game, set, and match."

would actually make sense, if I was actually trying to argue something. I asked a question. That post answers the question. The comment accompanying the link makes no sense, as we weren't playing a game, or debating anything.

Like I said, I don't fall for flame bait. But nice try on you also.

# this *****ing idiot above — Guest 2007-08-31 03:58

jesus christ! he DOES effing mention it - second to last paragraph. *****sucker. Try reading the whole article before showing off how small your ***** is - what kind of a moron posts like that? ARE YOU *****ING BLIND!!!! geeeez....

# free play — Guest 2007-08-31 04:04

ok *****wit but please, read the whole damn article - the "qjidiot" included that information in the second to last paragraph so WHAT THE ***** ARE YOU WHINING ABOUT!!!!!!!!!! ! i quote from the article " the method will only work to boot 150" and what are you claiming they didn't mention - !!!only being able to boot 150!!!!!! YOU BLIND *****ING IDIOT.

# freeplay — Guest 2007-08-31 04:07

comment above refers to freeplays original comment not the reply above.

# ... — Guest 2007-08-31 04:08

People that write Sony with an "$" deserve to be shot...

# ***** — Guest 2007-08-31 04:15

***** ADVERTISERS

# ... — Guest 2007-08-31 07:19

Yes, i was referring to FreePlay's half-assed claim.

FreePlay - "Had you bothered to continue reading what Mathieulh and Dark_AleX have said about this, ONLY 1.50 WILL WORK."

But QJ DID say - in theory. FreePlay is just being his usual flame-first-then-read self. Nothing new here.

# . — Guest 2007-08-31 07:54

Ah yes, in that case, then yes it does make sense. ;)

# using it again — Guest 2007-08-31 09:56

my friend is on a 2.82 firmware psp. if he uses the pandora battery/this, will he be able to use the battery as sony intended (just powering up the psp)

i know he can just upgrade and use gta/lumines but please answer my question.

# FIRST — Guest 2007-08-31 12:41

what's the big deal of being first??!?!?

# . — Guest 2007-08-31 16:31

Sometimes when your life is so empty and meaningless, even something as simple as being first poster can be exciting, because that's the only thing that they'll ever be first at in life, unless you count failing.

# -_- — Guest 2007-09-01 09:07

Testicles. Plain and simple.

# Dear QJSpammers — Guest 2007-09-03 04:28

The article was EDITED to mention that it only boots 1.50. It previously said you could use this with ANY firmware.

Try again, **********s.

# Y'see, here's the thing kiddo — Guest 2007-09-03 04:31

"They said IN THEORY it could be used with other firmwares, but not yet."

But that information was KNOWN TO BE WRONG WHEN THEY WROTE IT.

That's why QJ's writers are idiots :)
