Are you ready for homebrew? 3.03 HEN and Downgrader released!

NOTE FROM AURI: We're currently testing everything, so expect us to upload the complete downgrader in a few days. Thanks!

Fanjita may have told you guys what to do with a non-homebrew capable PSP, but now it appears that everyone can get in on the homebrew fun! The "goofy exploit" which exists in firmwares 2.00 to 3.03 was found on Friday, January 25, 2007, a date which you'd think might go down in the PSP homebrew history. But it probably won't because despite their seven-day ETA, the Noobz team has once again fortified its position at the top of the homebrew coding ladder with a 3.03 downgrader - just three days after the exploit was found!

Some call it magic, others call it an act of god, but whatever the reason for it, PSP gamers all across the world can now downgrade their consoles to the magic of homebrew-capable 1.5, and then if they wish to do so, upgrading to homebrew-capable custom firmware. All you need is a PSP running firmware 3.03 (if not then update to 3.03 using the update EBOOT found here) the downgrader files and the 1.50 EBOOT as well as an unpatched version of Grand Theft Auto: Liberty City Stories.

Unpatched versions of Liberty City Stories contain the 2.0 update, whereas patched versions contain higher updates. If your copy of LCS has an update higher than 2.0 on it, then you will have to find an unpatched UMD to proceed. There's no need to worry if you have a TA-082 PSP as the downgrader will check your motherboard and patch it if necessary. Note the downgrader will not let you proceed without patching if your motherboard requires it.

Not only has Noobz released a 3.03 downgrader but they've also managed to release a 3.03 HEN (Homebrew Enabler) for the PSP. This means that those of you who aren't too sure that you want to downgrade can still play homebrew on 3.03. This does not flash your PSP, but 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. You run the HEN application just as you do the downgrader using Grand Theft Auto: Liberty City Stories.
