Zitat von Dark_AleX
Yeah, the "Service Mode".
This has been the work of the alliance of a lot of developers externally known as "C+D": Nem, joek, Fanjita, Chris, jim, psp250, ditlew, Skylark, Dark_AleX (Me), mathieulh, tyranid, adrahil and Booster.
The battery lets to downgrade any firmware version (including those that Sony releases in the future), and to unbrick bricked psp's (whatever bricked by software psp, not only the ones bricked by that retard of Serafin), in all current hardware. Of course, we cannot be sure about future hardware, but the Firmware Update game has finally come to the end for all current psp's.

USAGE
- Insert Memory Stick into the PSP
- Remove power cord and insert the JigKick Battery into the PSP.
- A menu appears when the PSP boots. Follow the onscreen information
and instructions.
NOTES AND RESTRICTIONS
- The firmware in the Memory Stick is not a full 1.50, but a minimal
subset. Therefore, not all applications (such as flashers, or
recovery apps) will load.
- Only Memory Stick Pro Duo are compatible. Memory Stick Duo
(e.g. 32MB sticks) are not supported.
- The IDStorage cannot be totally restored, as there is no known way
to regenerate it properly.
- It is strongly RECOMMENDED to make a flash dump of the PSP before
any downgrading operation.
- There might be a BSOD at the end of the downgrade. This is normal,
and happens on the standard downgraders.
- All hardware revisions known at this day are supported.
- This release contains no Sony-copyrighted material. All required
Sony data is generated from the v1.50 update files.
