I follow the softmod guide here: https://gbatemp.net/threads/how-to-softmod-hack-your-psp.293978/ in an attempt to be able to run homebrew on my psp 3000. I was originally at 6.60 and used ChronoSwitch to downgrade to 6.20 but I wasn't able to get 6.20 PROC2 to install, I just got a perpetual black screen, so I wanted to try and restore it back to 6.60 I now believe that I'm stuck as when I try to upgrade back to 6.60, it says the data is corrupted. I tried running Frostgater's TA-095 Upgrader and it says it's corrupted. I tried re-running 6.20 PROC2 and I just get a black screen. Can't get online, can't run homebrew, can't upgrade/restore back to the original state, it seems like my psp is now sort of soft bricked. If it helps, when I go into System Settings, it says I'm on 6.20. I can't run PSPident 0.74 either, it says the data is corrupted. Any help or suggestions would be greatly appreciated. Thanks for your time.
