Noobz has released a new downgrader for PSP, this time v3.03 PSPs can be downgraded to v1.5. The downgrader doesn't work on other firmware versions, but if one has v2.81 - v3.02 firmware, he can upgrade it to v3.03 and then use the downgrader. Ultimately this means that all the PSPs out there can run homebrew and according to Noobz the downgrader is easy to use. Here are the details:

Some ground-rules:

* This downgrader is for v3.03 firmware only. But if you have v2.81 - v3.02, no problem - you can just upgrade to v3.03 to use the downgrader.

* You need a copy of the unpatched GTA:Liberty City Stories UMD. No ISOs, no patched UMDs, not Vice City Stories. See here for some info on how to check if your version is patched. The most reliable way : the unpatched disks have the v2.0 firmware update on them.

* This downgrader is intended to enable homebrew. Homebrew is NOT the same as piracy. Don't be a thieving loser - buy the games you play.

* The downgrader will work on all current PSP hardware (TA-079 - TA-086). Patching of TA-082+ is automatic in the downgrader.

* You downgrade at your own risk. There is always a chance of bricking, although we have done everything we can think of to make this process safe.

Full instructions for downgrading are included in the Downgrader_HOWTO.txt file in the ZIP file. Read them carefully! You will need:

* The 3.03 downgrader package

* Official v1.50 Firmware Update EBOOT

* Official v3.03 Firmware Update EBOOT (only if your PSP is not 3.03 already)

Warning: After downgrading from 3.03 to 1.5, there are some remnants of 3.03 left in flash. If you later try to re-upgrade to 3.03 and repeat the downgrade, things will break. At some later point, we will work on a cleaner that will remove these extra files. Until then, enjoy! (Don't worry, upgrading to 3.03 OE firmwares still works fine).

Hey, I agree with the noobees out there. The 3.03 downgrader is not quite 100% clear. I had the same problems as a couple of the earlier posts. The how to says :

"Unzip the 1.50 update to a temporary folder. Rename the EBOOT.PBP to UPDATE.PBP" but I found this did not work. But it worked if I just renamed the file to "UPDATE" without the ".PBP" extension.

I hope this helps some of the guys just starting out like me.

Sweet. I might just upgrade to 3.03 now since the downgrader & Hen are out now on that firmware.

does any1 know if there is any way i can downgrade my psp with liberty city stories even though it has a 2.60 upgrade on it?

Comment by: junaidrq (Feb 12, 2007 18:05)

Does this method work with all psp motherboards??
And how can you identify if the gta lcs UMD has a ver 2.0 or is unpatched??
Thanks for your help

Comment by: chaos2469 (Feb 12, 2007 20:30)

yes and if the update on the gta:lcs umd is 2.0 its probably unpatched, if its above 2.0, its patched.
hope that helps.
btw the downgrader will automatically patch your motherboard if it needs it, it will prompt you before it patches it, you dont have to anything other than what the read me tells you to, it pretty much is automatic.

Comment by: junaidrq (Feb 12, 2007 20:40)

my last question is that if i buy a new gta lcs i wont be unpatched or i wont has any way of knowing if it has version 2.0 or not.

For those who say that the 3.03-1.50 downgrader doesn't work,

I was stuck on 2.81 for 3 months and I had nothing to do but, as a gift, I got Grand Theft Auto: Liberty City Stories so I used for the downgrader and it worked! I upgraded from 2.81 to 3.03 and then downgraded to 1.50! So I'll explain the process:

You need:

1) A 1.50 EBOOT.PBP file from Sony (a website is given within the README.txt).
2) a 3.03 EBOOT.PBP file from Sony (a website is given within the README.txt).
3) Any Grand Theft Auto: Liberty City Stories (North America).

Instructions:

1) Update to 3.03 by putting the EBOOT.PBP (the 3.03 one) in the UPDATE folder within the GAME folder in the PSP folder (PSP>GAME>UPDATE)

2) Load it from your PSP in the Game menu, in the memory stick and update.

3) Once you've updated, delete the EBOOT.PBP from the UPDATE folder.

4) Copy the contents of MS_ROOT to the root of your memory stick.

5) Rename the EBOOT.PBP (the 1.50 one) to UPDATE.PBP (do not overwrite the EBOOT.PBP that will already be in the UPDATE file).

6) Load Grand Theft Auto: Liberty City Stories. When it loads, a light blue screen will appear and the PSP will reset itself.

7) Open your PSP, go to Settings, System Setting and in System Information, it should say 3.03 HEN.

8) Go to the Game menu in your memory stick and load the x.yz program.

9) It will ask you to press X if you want to downgrade and if you want to cancel, press R.

10) Wait patiently until the PSP will reset itself and hopefully, you will be in 1.50!

Download the downgrader from www.noobz.eu/download.html

Comment by: junaidrq (Feb 12, 2007 22:43)

does any GTA LCS work in north america
if not
how would you know if the game is unpatched or has ver 2.0 if it is packed since you cant open the case before buying it.

At some later point, we will work on a cleaner that will remove these extra files. Until then, enjoy! (Don't worry, upgrading to 3.03 OE firmwares still works fine). "

Does anyone know if this could affect the function of certain ISOs? I ask because I have two PSP's, on my old one I can use a backup of xmen w/ no issues but on the one I used the 3.03 downgrader on, the thing skips and stutters during the intro and during gameplay? Really strange. I know the ISO itself is fine because it works on the other PSP, I've tried formatting different memory sticks but it only happens on the 3.03 downgraded PSP.

Anyone have any ideas whats going on here? My homebrew and other backed up ISO's I have work fine. Ironically, the only reason I use the above ISO is because the UMD lags too much. scratching my head. . . .

nads, if you follow the step by step instructions posted here and in the readme, you will be fine. Just take time to read them, make sure you have the three needed files and you'll be straight. Its really not that hard bro.

You need GTA: LCS with 2.00 upgrade! you guys are morons and should of searched google long ago! I bought Five different kinds of GTA and the ones with 2.00 updates worked ONLY! I will send you free betas of downgraders for 3.30 if you are nice;) I will even send it in a nice easy install program! it's a beta so BE CAREFUL IT MIGHT BRICK YOUR PSP IF YOU RE-UPDATE TO 3.03 AGAIN. YOU ALSO TAKE THE RISK OF BRICKING BY USING ANY DOWNGRADERS SO IT'S BY YOUR OWN RISK! Buttttttttttt, the people who made the downgraders made sure you had a small bricking chance

DO NOT COPY THIS (Ha they'll never figure out this one!)

i downgraded my psp from 3.03 to the 1.5 with the easy downgrade software.worked great as far as i know.but my question is mostly because i don't understand why a few of my functions have stopped.i can't listen to music or look at photo.granted they are not the best features but i likes them.now i just want to know is now that i downgraded with this program is it possible to go back to a newer version of firmware,maybe i'm not looking at everything.but i would rather not be stuck in this situation but here is my bed and i gotta lye in it.
