So I just upgraded my PSP from 3.04 EO-C to M33 3.52 and through all the updates till 4. It went all nice and clean. Lacking a USB cord atm I decided to install PSP Wardrobe (the newest version) and put a couple themes on there. It workded all nice and shiny, so I proceeded to install the new IRSHELL. I installed the ....iso patch, it seemed to be working. I then quit IRShell and opened PSP Wardrobe again, this time testing out the "The Wheel" theme. The flashing bar went along as normal, but for some reason went from two "diamonds" to one then to three and four. It said installation was complete, but something is really messed up. It is impossible to start my PSP without going to the Recovery menu then pressing quit. I have restored my XMB in Wardrobe a million times and I still get the same problem. Anyone think they know what my problem is, and know how to fix it?
Go to recovery, advanced, activate USB flash1, and delete all the files.
edit: never mind thank you sir I saw what you did there. Working like a charm.
