Greetings. I tryed to switch from 6.20 TN to 6.20 B5. I started by putting all the necessary folders (excuding sdk) in PSP>GAME. I tryed running the installer from TN, but it said I needed to be on a version of PRO. I searched, but couldn't find a version of PRO for 6.20 previous to B5 before I found that I could run the firmware from the updater, which I did. I ran the installer. It asked to test something which I didn't know what it was, but I agreed. Then I ran the updater again to run the CFW,since I couldn't run the installer otherwise, but the PSP just turned off. After attempt 2, I decided to select 'uninstall'. Now I could run the firmware from the updater again. I ran the installer but this time disagreed to testing whatever it was asking me to test, it installed, and now my PSP Go won't turn on. Can I still use my PSP or am I stuck with a very expensive paper weight?
EDIT: This is a 5g model PSP. I can boot into the recovery menu. Please help? EDIT2: I just realized I can boot into OFW, but I can't run the updater to attempt uninstall nor can I run the recovery eboot.
