Dark_AleX has released version 4 of his Despertar del Cementerio universal unbricker. This, in conjunction with a Pandora battery, can be used to unbrick any PSP as well as flash custom firmware, no matter what firmware you’re on. Works on both fat and slim PSP’s.

Changes:

• Installer now checks if user has a custom theme installed, and ask him to disable it before running the program.
• the PSN DRM file in flash2 (act.dat) is now backed up during ms creation and restored in the unbrick.
• flash2 is now formatted too.
• Now installs 3.80 M33-5 instead of 3.71 M33-3.

Make sure you check out the readme for installation instructions. If you buy games from the PS Store, be sure to read the two notes at the bottom of the readme, too.
