OK peeps. I have two PSPs. Both were running firmware version 2.71. I used Dark Alex's downgrader to take them down to 1.5 f/w and up to Dark Alex's 3.10 OE-A firmware. The first PSP was successful!! The second read below... On the second unit..when I got started the battery was 50% charged. So I connected it to the charger and let it charge for a bit. I checked the charge about 30 minutes later. It was at 87% so I figured I was ok to start the downgrade to 1.5 and connected the charger just in case it ran low on juice. I started the downgrade. It was looking good..then the I noticed the screen was blank. After flipping the power I noticed the the downgrade appeared successful even though the screen was flashing in and out. I disconnected the power cord. The screen lit up. SO I checked and it said I was running 1.5 firmware. So I put in the flash with 3.10 f/w and started upgrade. After it appeared to have started the upgrade the screen went dark. So I figured maybe the power was low. So I connected the power. Still the screen was dark. So I didn't know what had happened. So I pulled the power cord...ntohging happened...tried holding the power button...still nothing. So I finally removed the battery to be able to shut down the PSP. Now when I turn it on. All I get is a green light...the memory stick flashes as if it is trying to be read...the screen appears to want to light up and that's it! :-( The only way I can turn the green power light off is to remove the battery. HELP ME OUT SOMEBODY!! Is it permanently gone? It is a partial brick? Recoverable brick? If it is bricked...how can I recover it? If it is only the flash memory on the MOBO that is bad...could I just replace that part on my motherboard as oppose to replacing the whole motherboard? Anyone know the exact flash part and part#? PLZ REPLY!! Thanks. I need it fixed ASAP.
