I think my PSP just got upgraded

I was taking a crap and playing my psp :D and when i was done I exited SNES EMU and went back to my computer to do some crap. I turned on my PSP to see that dev hook was on so i was like " eh no big deal" so i run the Go back to version 1.50. When its done loading to go back to version 2.71. I try this a few more times and it doesnt work.

Things that could have affected it:

I used Theme PSP And kept switching back and forth between Final Fantasy Theme and Prince of Persia Theme.

I installed the themes on every single firmware because I couldn't figure out where to install it.

I deleted PSP set (by accident) from my memory stick

The plastic on my memory stick is kind of coming off now.

I can just downgrade again but i dont want to mess up my psp by constantly doing this if it gets upgraded again.

So you are saying its stuck on 2.71 do a hard reset,pull the battery out that should fix it

Nope its still stuck at 2.71. I think it got upgraded, but all the things for devhook are still there (wallpaper, nickname, etc)

Do you have custom firmware?
because that's probly your problem flick your wifi switch into the position it's not in and try again.

Thanks Kramer, it worked!

thats ok dude.
