About two three or four hours ago I used M33-4's Network Update feature to upgrade to the (apparently) latest firmware. I never checked which version it was updated to, but I'm guessing it was probably M33-6 since that's the latest version.
Anyway, after the update I decided I would format my memory stick to get a fresh stick to begin adding homebrew. After the format, I rebooted and nothing happened.
No M33, no recovery, nothing. Just the green light indicating there was power going through the PSP.
Since this isn't a flash problem, I was wondering what files of the memory stick let the PSP boot? I don't have any access to another PSP for about another week, so Pandora is out.
I'm hoping I can just get the files I need, put them onto the memory stick, and the PSP will boot. Any ideas what files I need and where I can get them?
