When I try to load firmware 2.0-2.6 on devhook it will shut off my psp. I wanted to go to them because I wanted to use the cheat thing for GTA-LCS. I am using devhook 0.46. what should i do?

i do not know, but have you heard that devhook is messing with copyrighted files, that is unleagal

Perhaps you do not have all of the proper files? I believe that you need to actually get the reboot.bin file from the internet or something for firmwares 2.60 and 2.71. (Because the DevHook firmware installer does NOT make the reboot.bin for you) My suggestion to you would be to use firmware 2.5 instead. For some odd reason the DevHook firmware installer WILL make the reboot.bin for firmware 2.5. And If you just want to use the cheat device then 2.5 will work because GTA only requires 2.0.

then u should just get the full package of an older release
but u better start looking fast because they won't host them n e more because of the legal issues

I fixed it now. I just needed the reboot bin stuff. That sucks how it going to be illegal.
