Okay, first off, I guess I should say hi. So, hi. Now onto business. I have a psp with firmware version 1.5 which it has alwas had. Since I have had it I have used various homebrew applications, that besides what I as using them for I knew little about. I now want to undo all that, if at all possible. I think that some of the programs I've used (devhook, UMDloader, some others) need to change some of the psp's files to work, like eboot or whatever, and was wondering if there was any way to wipe all that clean, so that as far as my psp knows, it is once again a straight out of the box, unhacked, unaltered, 1.5 PSP. Does anyone think this is possible? Thanks alot for any help you can give me, ive been posting on psp forums for a while trying to find out, and they all seem pretty lifeless. You guys see to be a more responsive bunch, so hopefully I'll be able to get some help. Thanks again.
