if i were you i'd try flashing 3.02OE-A(update to B after) again and this time keep you fingers crossed. as the 3.02OE-B Rocks so good luck if you do try again
p.s. if you do you can save the contents of the oeflasher and if any more mishaps you can reflash the 3.02OE-Awith out going to 1.50 by copying the "oeflasher" folder contents to psp\game\recovery\ and run the recovery eboot again. best of luck

I've upgraded my psp w/ no problems was a v1.5 w/ a 2gig stick. I upgraded to 3.02OE-A then OE-B all is well! I tried my son's which was a v1.5 also with a new sandisk 4gig stick and I'm have big problems. It flashed 3.02OE-A no problem but I cannot upgrade to vOE-B, it just shuts down. So I figured I would just leave it be for now and let him play. Well the only iso that will play is NFScarbon, nothing else will play. So I figured I would go back to v1.5 and try again. Well no dice....every time I put the recovery files back into the game folder and exit out of usb mode all the files in the game folder change to this....

G:\PSP\GAME\RECOVERY\RECOVERY\RECOVERY\DATA.BIN, ICON0.PNG, PARAM.SFO

no matter what I do I can not seem to fix this. I tried pulling the ms stick out and it booted just fine, so I reformated the ms several times and when I went back into it there was a bunch of differed folders in there. So I deleted them and copied everything over the way it should look on my other stick and still no dice.

Can someone please help?????????????????????????
