I've already downgraded and upgraded 1 PSP before. Both from 3.50 to 1.50 to 3.52M33.

On the new one (IC1003 TA-82, I don't think this matters tho), I have M33 installed, and when I go to try to run an ISO (legally ripped) with a UMD, it will load to a black screen. I went to recovery, turned ON no umd, and the game works, but when I go back to the XMB, it turns off.
All other settings have not been altered.
I had a similar problem with my other one, and I downgraded back to 1.50, then reupgraded to 3.52M33, and fixed it fine. On the new one, the same problem persists.
Any suggestions?
Thanks

I wish I had suggestions...only confirmation. I too have a T-82, and when I upgraded to 3.52M33 - the "Execute BOOT.BIN in UMD mode" would reset itself automatically. I thought it might be due to my use of a custom .jpg background, but who knows. I went back to 3.40 OE-A as no-one had suggestions. Hope someone has some answers...
