Yea only thing I can think of and adding to beldandy561 comments..the firmware/sd flashing are very temperamental...I also have the old version 2.1 and had various problems with crashing, standby not prompting back on with power button, emulators not running, black screening etc.. I found that the corruptions would eventuate while transferring roms or files from pc to device, either the USB might get slightly bumped or the drive is not thoroughly and properly ejected, files not transferring properly, then other times it seemed to be just the flashing itself. However by sheer persistence after maybe 3 or 4 image flash retries I can get it running smoothly, how? I dunno, temperamental I guess (not exactly top o the line quality hardware lol)....so possibly a reflash on next update or something like that...also don?t forget to save your game save folders somwer before reflashing....got to disk 3 of 4 in ff iv and well yea just don?t forget to save anything u wanna carry over...also try different rom set of gb?s as well maybe?
