My PSP shows in system settings that I am running "3.03 OE-A" I bought a new PSP 2.71/TA-082 and downgraded it to 1.5 yesterday and then upgraded it to 3.03 OE-A using the DarkAlex technique and files. It looked OK to me but I'm a noobie.

Today I tried to upgrade further to 3.03 OE-B. I discovered that my PSP doesn't recognize /PSP/GAME150/... It does recognize /PSP/GAME/.. but could not run the upgrade game in the /PSP/GAME/.. folder (failed to load).

I am now suspicious that I simply managed to upgrade to plain jane 3.03. Is there a verification criterion for each upgrade version? How do I know what I've got. Am I missing something simple here?

After I got going in my supposed 3.03 OE-A, I reformatted the stick. Is that my problem?

Any help will be much appreciated!
