"Downgrader" for 1.0 PSP Users! Go back to 1.0 after using 1.50 Firmware!

Fw1.0 Backup and Restore Tools

That mad scientist 0okm is at it again. And this time, it's something pretty revolutionary. He has just managed to write a program which can flash your 1.5 PSPs to 1.0, provided that you've backed it up using his tool. This isn't a true downgrader since you can't actually downgrade your original 1.5 PSPs, or even the 1.0s unless you've backed up your firmware with it. But if you're one of those lucky people to still have a 1.0 PSP, rejoice! You can actually take a trip to the 1.5 firmware, and come back home to 1.0!

How is it possible? Well, in simple words, it's just copying the firmware to the memory stick and later, just re-flashing it again. But then, why wouldn't a normal firmware file work, like in the 2.0 downgrader? Under the circumstances, I'll assume that all the files in the flash are somehow encrypted differently for every PSP. That's why it isn't accepting files from a different PSP. It will only restore your firmware if the backup is taken on your own PSP.

And this comes from the guy with the multiple firmware hack which we covered some time back. Seeing all his wacky projects, I'm pretty much sure he has a bunch of stuff up his sleeve. What exactly, I can't tell you because I myself don't know. But whatever it is, I'm waiting with bated breath. For now, enjoy this backup and restore tool for your 1.0 PSP.

The download file is locked by a password. You should open the attached README and find it out yourself since it carries an important message. Please make sure to read the README because it also mentions a lot of info which you should be aware of before embarking on this adventure. And as with every firmware tool, it is risky. Make sure you know what you're doing. Neither 0okm, or QJ.NET accepts any responsibility if you burn your hands badly with it.

But if you're still dying to try it, download it using the link below. And thanks for the tip i386!

# waw — Guest 2006-05-23 06:38

so this means if i back up my 1.5 firmware now, if a future kernel mode hack comes for 2.01+ i can upgrade and downgrade at will?

# w0w! — Guest 2006-05-23 06:39

post #1!

This is great news for 1.0 users! and you're right, this is revolutionary!

WELL DONE!

# whats the advantage? — taemo 2006-05-23 06:40

sorry, n00b question but..

whats the advantage of 1.0 vs 1.5?

# #1 — DiabloTerrorGF 2006-05-23 06:40

Quite possible, but first we need to get more than the limited usermode that's available for 2.01+.

I wouldn't risk it right now though.

# hmm intresting — Guest 2006-05-23 06:40

looks like we have some good progess here. slowly sony, we inch closer to the ultimate goal of ultimate downgrading for iso capability! mwhaha!

# - — Pranav T 2006-05-23 06:41

Please don't upgrade upwards of 2.0.

And if possible, not even above 1.5. Nobody can guarantee the results of this tool if you go over 1.5

# this is raw — Guest 2006-05-23 06:41

props to this guy. made it easy for all those 1.0'ers that never wanted to update. 1.0 & 1.5 oooo !!!

# It's good but... — Guest 2006-05-23 06:49

there's not much point in upgrading to 1.0, there's only a few extra games that work with it. Most games now need 2.0+ so you're knackered whichever firmware you use (at least until a new loader is released anyway)

# upgrading to 1.00 — zodionic 2006-05-23 07:02

You'r not realy upgrading or downgrading to 1.00, you'r just restoring your flash from you'r origional 1.00 firmware

the only reason anyone would do this is so they can upgrade to 1.50 in the knowlage that if any custom firmware comes out (most likely any custom firmware will only be usable on 1.00)

they can replace the origional flash.

1.00 isnt better than 1.50, the best way to describe it is 2.00 without the webbrowser and any new game support etc. but homebrew is accessable through game menu without any exploit.

# Is this possible? — dylr91 2006-05-23 07:28

Isn't it possible if someone backed up their 1.0 files and hosted it on the internet so a person with 1.5 PSP could copy the 1.0 files to the memory stick and downgrade?

# induvidual to each psp — Guest 2006-05-23 07:34

no, read the post

did you not read the full article?

# Awesome — Guest 2006-05-23 07:44

That's neat...but if only it worked on ALL 1.50 firwares to downgrade to 1.00 firmware... Either way though, eXcellent WORK!!!

# fdsa — Guest 2006-05-23 07:44

There is a Backup of a 1.00 somewhere just have to find it (dont google go to other psp news sites)

# nice progress — Illegal Machine 2006-05-23 07:54

But Pretty much useless to like 97% of the people who are lookin at this..

I suppose theoreticly, one could go all the way up to 2.0 with this.. Backup, upgrade to 2.0, downgrade to 1.5, restore with restore tools.

but then again, if its only good for 1.0 users who cares I guess...

at least this gets people one step closer to being able to downgrade to 1.0

# workaround — Guest 2006-05-23 07:58

what if somebody made a generator that you put ur mac address in or sumthin and it will make a personal 1.0 backup

# Good Idea — Guest 2006-05-23 08:03

nocomment

# Good Idea — Guest 2006-05-23 08:04

Good Idea but only if it came out like a year ago, I think most people who had 1.0 psp's is already at 1.5, but its better late than never ;)

# Question — Guest 2006-05-23 08:09

If you have a 1.0 PSP, is it possible to upgrade any further past 1.5 and then back down, or is 1.5 the limit?

Also I thought that when you use the 2.0 downgrader, your PSP becomes 1.0 until you upgrade to 1.5. Is this not true 1.0 or something? Did Sony ever release 1.0 PSP's in the U.S.?

# He is working on downgraders like this — Guest 2006-05-23 08:57

I remember he is going to make a downgrader by using the mobo board.

# tight — Guest 2006-05-23 09:07

this is cool. You should compile this one and the 2.0-1.5 downgrader all in 1.

# .... — soopergooman 2006-05-23 09:15

i really really really hope that he does what is on alot of peeps minds. that is to find a way to downgrade from 2.7. hopeless wish i know, but a valid one. luckily I have a 1.5 also...

Keep them Hacks a-coming doob!!!

# Dam — Guest 2006-05-23 09:17

if i only my psp was still a 1.00...

2. I *****ing love 0okm!

3. Start work on 2.6!

Go you *****ing Genius!

# I like the idea — Dragon Claw 2006-05-23 09:48

This is somewhat of a good idea but I kinda see it pointless. I mean both 1.5 and 1.0 can play homebrew right so why upgrade and downgrade. Maybe just to play some iso's or homebrew then yeah I get the idea but still.

does this run gta ?

# What about higher firmwares? — Guest 2006-05-23 10:37

Could something like this be done for 2.x firmware? For example, 2.0 > 2.60 > 2.0?

# i dont see the point of this... — Guest 2006-05-23 11:11

wat r advantages of 1.5 and 1.0?

besides not using kxploit?

# crap — Guest 2006-05-23 11:19

i thought that i might be able to downgrade to 1.0 to just see how much better it is that 1.5 cause my freind wishes he had a 1.0 but idk what is so great

# remove my post? — Guest 2006-05-23 11:19

Remove my post? Because you know I'm right. Completely useless. The next time i see downgrader the words 2.xx better appear next to it.

# cool... — Guest 2006-05-23 11:38

It's nice to know that some of the devs out there still consider us 1.0 owners...But I can't for the life of me think of one reason why I would upgrade my psp...

# 36 — Guest 2006-05-23 12:01

I'm sure he and everyone else on this site is very intimidated by you and will be sure to have your statement in the back of their head before making another downgrader post. =)

# Q? — Guest 2006-05-23 12:08

I got a 1.00 but am quite afraid to use this tool since i haven't read about ANY succesful reports or any reports at all for that matter.

Did anyone with a 1.00 actually tried this?

# FW 1.0 — Hazror 2006-05-23 12:08

Like someone said above but no one answered; doesn't the 2.0 downgrader bring your psp to 1.0 then you upgrade yours to 1.5?

# no hazror — Guest 2006-05-23 12:21

the mph downgrader only brings u down to 1.5. Theoretically, you could back up your 1.0 upgrade to 2.0, downgrade to 1.5 and then downgrade to 1.0. The only reason to have 1.0 is the ability to install custom firmware onto psps, which is impoosible on 1.5+. Imagine having 2.7 capabilities with homebrew capabilities, and that is the idea of a custom firmware

# Frustration!! — Guest 2006-05-23 12:44

"Remove my post? Because you know I'm right. Completely useless. The next time i see downgrader the words 2.xx better appear next to it."

I posted this comment earlier. Just one month ago I had a version 1.5 psp until it got wet and it died. Retuned it with the warranty i bought and now i have a version 2.01 psp. All i want is streaming video on my psp. I would get the location free player but i bet the sound volume sucks just like the volume on UMD movies suck. I could care less about ISO loaders. When i saw downgrader and learned i could not use it i simply snapped. I apologize to all in here and all that try to get stuff working.

# Blah. — Guest 2006-05-23 12:52

I have a 1.50 that I updated from 1.00, do I need to find another one on the internets that has a backup of it?

# huh? — Guest 2006-05-23 13:08

No, if you upgraded to 1.50 without using this tool, it stays that way.

You needed to use this tool for the upgrade.

MPH downgrader is a version tricker to 1.0, not an actual downgrader.

The 1.0 version tricker allows the 1.50 updater to work,

but it's never really a 1.0.

# YEAH!!!! — Guest 2006-05-23 20:00

It DOES WORK. I was a bit scared at first, but I've successfully upgraded to 1.5 and gone back to 1.0 with no problems whatsoever. Now I can have the comfortable 1.0 firmware without two folders per app AND 1.5 when I just want to play some backups.

Man, this is great. Thank you, 0okm.

quick question, can someone direct me a link on which files to use for the mph firmware downgrader, im trying to run some umd movies on 2.5, but for some reason , its frezzes on menu screen. you cant even see the menu just a blue screen. plz , thanks. i didnt get any 2.5 flash 1 files when i used the firmware dump from the psar file. thanks

# Backup your FLASH now!!! — Guest 2006-05-24 22:16

Everyone on 1.5 or 2.0 firmware should now back up THEIR flash, so when we find flash write access on 2.01++ we will still be able to downgrade! regardless of the index.dat being encrypted.

Onequestion i got for the developer of this, when the 1.0 Firmware is backup, do you just copy all files on the flash to the memory stick or is there hidden data on the flash not accessible via sceIoOpen??

# #20 — Guest 2006-05-25 15:21

Yes. I asked 0okm on MPH's forums and he said it's possible.

Still, other than "Mike"s quick claim in an unregistered post, no-one seems to have tried this yet... I've looked on multiple forums too.

I'm sticking with 1.00 till I know this works.

For people that asked what's better about 1.0 compared to 1.5?

- No KXploit (tidier Game folder)

- Initial loading time of homebrew is a lot quicker.

- Possibility of future custom 1.5 upgrade, but that could probably be acheived by 1.5 users tricking their psp to think it is 1.0 first.

For people that ask why this is good news for them if they don't have 1.0 firmware?

The hardcore people that have stuck with just one firmware 1.00 psp, who may be knowledgeable coders, may now be able to help with things like:

- improving umd/firmware loaders

- developing downgraders

- finding security holes like the gta one (which us 1.0 fw users could not find as good umd loaders don't work yet on 1.0)

But we still need a bit of confirmation/evidence of this program working...

# not working... BadBlock found — Guest 2006-05-27 22:09

I just tried with my PSP with FW1.0. The program terminated because a BadBlock found. Just wondering how many people really succeeded backup their FW1.0?

# . — Guest 2006-05-28 15:41

DOWNLOAD LINK DOES NOT WORK

It wants you to pay $0.00, add to your cart and buy it

wtf?

# A few more success stories — Guest 2006-05-29 03:51

More people have gotten this to work properly - I know these guys so we can call this confirmed. 1.0 users rejoice (all ten of us, heh)!
