It's been a while but I have a PSP 1000 and I have been running Gen-D for a while, recently I upgraded to 5.50 Prometheus. However ever since then it's been acting up. So, I was wondering where can I get the files to install 6.20 Prometheus-4 (if that's the latest one). I tried to reset to go back to OFW but it kept failing and my old MMS went to shit so I don't have any of the old files I used.
