PSP Downgrader Released

A PSP haceker going by the name of Noobz has released a new downgrader for PSP that can wind back v3.03 PSPs to v1.5.

The downgrader doesn't work on other firmware versions, so you'd need to upgrade from v2.81 - v3.02 firmware 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).
