Well, I had custom firmware, and decided to downgrade myself back to 1.5 then go to legit firmware. I mistakenly upgraded at the 1.5 stage via a UMD game to 3.03. Can't go any higher, namely to 3.5, because I'm blocked from legit firmwares past 3.something cause I had custom firmware.
Trying to get to 3.5 so I can use lumines to go back to 1.5 and then go to 3.71M33 and then upgrade to legit from there.
Any ideas? Since I can't upgrade to 3.5, can I somehow downgrade directly from 3.03?
