I doubt this will get answered since the PSP scene is a little dead but, here goes nothing. I bought this PSP 2001 and it came with 3.80 M33-5 installed. I tried updating to 6.60PRO-C but everytime I ran the installer, it would just hang on the white PSP screen and after a few seconds it would turn on the green memory stick light for half a second and then it would shut off completely. So after attempting to update to Pro-C, Pro-C2, ME-2.3, LME-2.3 and even Infinity, the console would just do the same thing, hang on the white PSP screen and turn off after a few seconds. So I read the PSP must be in 6.60 or 6.61 OFW to install the 6.6X temporary or permanent CFW, so I decided to download the update and place it on the memory stick UPDATE folder, but even trying to run that OFW would just hang on the PSP screen aswell and then shut off. I decided to try through the PSP's System Update option, I thought for sure it wouldn't work, but it actually did. It downloaded the 6.61 firmware and it seemed to have been installing just fine, until it reached 99% and an error came up, the error code was "Update error (LPTFFFFFFFE)", so I pressed X and the system shut down. Upon starting it up, I went to check the system version and it now says 6.61! So it did install however it now has issues. Whenever I try to install ANY CFW it just hangs on the white PSP screen again! I even tried to use chronoswitch downgrader and it still does the same thing. I formatted my memory stick (I've tried with 2 different sticks) and also restored default settings on the PSP (it also hangs/freezes as soon as it finishes restoring default settings and then turns off). I do have another PSP 2001 that does have 6.60ME-1.8 installed and working fine. Is there anything I can do here or am I SOL?? Thanks in advance, anyone!!
