psp slim brick

my psp turned off while pandorizing my battery for friend, but it turned off during the process so my psp slim is now bricked. i have a phat and its battery. i have a 2gig memory stick. i have been trying to fix my slim with CWF 3.90 m33, but it is not working. can someone please help me.

try to look for a despertar del cementerio autoinstaller, i think it is called despertar del cementerio v4 by Mr dune, it doesn't require you to have a CFW PSP

And plug in the AC cord next time you're doing anything like that
