Need help unbrick my PSP 2001 with official firmware as 4.01

Can anybody PLEASE PLEASE help me unbrick my PSP 2001 (slim) which has 4.01 as official firmware???

I bought a Pandora Battery from "dealextreme" http://www.dealextreme.com/details.dx/sku.12472
which actually does not fit my PSP properly....But when I insert my Pandora Battery it shows "green light" ... I have used Rain MMS to load 4.01 and other CFW...but of no use...When I insert Pandora Battery on my PSP it shows a black screen... with green light under power...I tried pressing L trigger etc...

Please help...It's driving me nuts....Is is possible to upgrade/downgrade an official 4.01 formware???

THANKS A LOT IN ADVANCE....

SK

so your psps bricked

the rains siple mms maker you need to install desparter del cementreio using your psp which would require a cfw psp

i say.....

try finding someone who already has hacked there psp or try manually putting desparter del cemnterio files on to your psp

find a god guide on google

A BIG "THANK YOU" to you my friend for pointing out to the right direction...I am going to give it a try today...

No Problem Thank You For the THANK YOU

If nothing works you have to buy a magic memory stick http://www.pandorasales.com/magic-memory-stick.html
This is the only choice!
Or you could watch this http://www.youtube.com/watch?v=GTWlW...eature=related if you have a recovery menu, watch it and you can unbrick it without a pandora's battery!!

Since you have a "Tool" batery, all that you need to do is get a prepared memory stick to boot it with the batery.
You can find programs like PandoraBox , or Easy Pandora Installer (i guess that it is the name), and such things which installs the necessary files within the Memory Stick without the need of a PSP with CFW. I used it to save a old PSP of me, for sure there is newer versions suitable from Slim PSP.

Hey, i got psp 2001 4.O1 too, but i cant unbrick. p.s. my psp is -2004is, friend said that this one is unbricible ewen with pandora, becouse i cant turn on recovery menu. I know that those psp models wich are yunger(like 2OO8) can be bricible.
