I am in need of help. I looked through the forum but I have not found an answer to my question yet.
I have a new PSP which I downgraded thanks to the great post on this forum. The PSP came with 3.11 . I got a lumines UMD and everything seems to have worked fine and then I upgraded the firmware to 3.40-oe. However, I am unable to play any of my .cso & .iso off the memory stick. I have an older psp with 3.03-oe-a' in which the same memory stick plays all the games. but, if I put the memory stick in the new PSP with 3.40-oe it does not work.
I can start the game but it freezez as it begins to load. then I have to turn off the PSP or pull out the battery. I tried re-flashing, I tried flasing the new psp to 3.03 oe-a' to be the same as my older psp but still no luck. the same problem always. I have tried putting different UMD's in the PSP and that did not work either. I can play the UMD's but not the ISO's off the flash disk. I also tried to reformat the memory stick but that did not work either.
Something else I noticed. If I go into the recovery console, I cannot access the "configuration" menu. all I get is a blank screen if I select it. again, this is only an issue on the new psp. All the other menues work but not the configuration menu...
I am sure this is something simple... but I can't put my finger on it ans I have been trying for the last 2 days.. Anyone can help?
