I was messing with my PSP the other day, after having not touched it for about a year, and completely forgot about flash0 and deleted pretty much everything there. Stupid mistake, I know. I now have a bricked PSP, and cannot access the recovery menu. When I turn on the PSP, the power light turns on for about 10 seconds, and then shuts down again. I am borrowing a friends PSP with 5.00 M33-4, and kernel's 1.5x and 5.xx. Every unbricking guide I have found requires 2.xx or 3.xx. I have a battery I would be willing to softmod into a pandora battery, at least temporarily, but have not been able to figure out a way to do it with the existing CFW on the working PSP. I also have a spare memory stick I would be willing to convert into an MMS (Temporarily preferred) Any help would be greatly appreciated.
