I followed the instructions at http://forums.maxconsole.net/archive/index.php/t-43396.html for a TA-802 @ FW==2.71 and it worked! However, I thought it was bricked. The AC adapter was plugged in the entire time, then after the downgrade, the PSP rebooted. I heard the boot-up jingle but saw no picture! I kept messing with buttons and hearing audio but seeing no image. Then the AC adapter fell out and the picture returned. Restored default settings, rebooted, verified FW 1.50, everything's cool. But that blank screen - DAMN THAT SCARED ME!!! Could I ask a few more newbie questions? Aside from the ISO loader, what are the benefits of upgrading to Dark_Alex's 3.10 OAE? Can the built-in loader handle CSO's or do I need Devhook for that? Also, will GTA:LCS, Gun Showdown, or LOTR Tactics force a firmware upgrade on first run? Thanks!
