3.03v downgrader & HEN for v3.03 Released - Newest PSP Firmware Downgradeable

[fro]

On a EU PSP, can I upgrade to the 3.03 EU Firmware, then downgrade to the 1.50 EU Firmware ?

The ReadMe for the downgrader links to US downloads at QJ, I guess it wouldn't matter to use the EU versions but I'd like to be sure.

Thanks

The US, EU, JAP firmware updates are all the same.

It doesn't make ANY difference.

Thanks for the quick answer

Do you mean that the files are exactly the same or just that using them for downgrading doesn't change anything?

Because I thought there were a few differences between the files, like the X/O swap, or the available languages.

Fanjita and Ditlew have released a new downgrader for the latest version of PSP firmware, heres the latest release info below:

v3.03 Downgrader

After much work over the past few days, we finally succeeded - we have an easy-to-use downgrader for v3.03 PSPs!

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

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).

HEN for v3.03 (final release)

If you're not keen on the risk of downgrading your PSP, you might prefer to use a homebrew loader instead. Well, we've thought of you - we give to you "HEN 303 - the Duff release" (named in the eLoader tradition!).

HEN 303 (short for Homebrew ENabler) works in the same way as Dark_AleX's HEN for 2.71 firmwares. By running HEN, it installs a patch in your PSP's memory, that allows you to run homebrew almost as if you had a v1.5 PSP. This patch remains in place until you fully turn off your PSP - it will survive the PSP being placed into sleep mode.

The requirements for HEN are the same as for the downgrader - you need the unpatched GTA:LCS, and a v3.03 firmware PSP.

You can view the readme.txt file in the archive for more details about how to use it. Remember that not as much homebrew works with HEN as it does with eLoader or v1.5 firmware. But we hope to release an eLoader plugin for HEN soon, that would improve that situation - and remember that the amount of homebrew that works with HEN is increasing all the time.

Note: a pre-release version of this file was leaked on the internet. It is dangerous and could brick your PSP - do not run it or distribute it. The authentic version contains the text "This is the official final released version of 3.03 HEN" in the readme.txt file.

when is it going to be non gta downgrader?

[Shrygue]

As soon as another exploit is found, I guess.

[bam16]

i downloaded the files and it says they are corrupted. does anyone know why?

[Shrygue]

Maybe it's a broken download? Sometimes when you download stuff from DCEmu, the file you download prematurely quits, rendering it corrupt as I have experienced it before. If that's so, try it again.

[bam16]

cool thanks for the quick reply. i will try again.
