To begin, I have a psp fat that use to have cfw 3.40 OE-A. While flashing a custome theme, accidentally I left out a few files. After I was done flashing and exit the proccess, is when I realize that I had a problem on my hands. The psp became semi bricked. Having a pandora battery and a 1gb memory stick, already set up with cfw 3.71-m33 files, I went ahead and put in the battery and memory stick. Almost immediately, the psp became unbricked. At this point, I had no choice but to install cfw 3.71-m33 and continue with the proccess. The psp began to function normal again but I seriously would like to down graded back to cfw 3.40 OE-A. This is the way it was before the flashing. Would anybody tell what are my options or need to do. THANKS....
