can someone help? I have a official firmware 3.8 and a Datel service mode battery ''SLIM'' and i want to downgrade but It won't. help!!

[dizzyrizz]

So I just got a PSP Slim-2001, and not knowing any better upgraded to official firmware 3.80.

Is there anything I can do to get to a custom firmware??

I have an extra battery and Memory stick I don't mind "parting with", to make a pandora battery and magic memory stick. (I've only done a few hours of reading, so know that I am relatively new to this).

I would really appreciate any guidance you can give!
Dont want to brick my new PSP my girlfriend would have my head..

ok it says it cant do a full nand restore, heres my question i have a psp i believe it was 3.03 oe c or something like that, well in a half hazzard attempt to change the fonts and make more space, i deleted both flash 0 and flash 1, has anyone sucessfully repaired a psp with a similar issue? if so i can have a psp by tomorrow, but i dont want to go rent one if its been proven not to work.

edit: btw its one of the phat early model psp's, never had any problems with it since this.
