Hello all, I have a psp with a 2.60 firmware on it. I have read that you need gta to downgrade. Is there any other option at this point that I can use to downgrade without the gta game umd? I don't have this game and I am anxious to downgrade. I was looking to downgrade to 1.50 or whatever version that lets' me play homebrews and iso of my backups. Is it possible to update the firmware to a higher revision and then downgrade without the need of gta? thanks in advance!
