Hacking Psp 3000 Stuck on a corrupted/unupgradable 6.20

[ColdForge]

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.

Why didn't you just use the infinity cfw? Hate to say it but you're more then likely bricked some how now.

I had the same trouble. Infinity worked well.

I wasn't aware of infinity CSW, I don't think it was mentioned in the guide that I found in the forums here. Any links for this?

Was there anything special you had to do to get out of the state I'm in? I'm going to try using Infinity CSW and hope that it works...

Yeah, I think I'm SOL, I tried to open 6.61 Infinity Firmware Builder after following the directions and it says it's corrupted... sigh. If someone could find me a way to restore other than buying a new PSP I'd be extremely grateful.

Try downgrade again and do the infinity process to see if change. Also try to downgrade to another low firm first.
Building have two options if I remember. Try the one you dont had bricked.

Using ChronoSwitch v7, it says my firmware isn't supported. Is there a different downgrader I should be using?
