downgrade 3.52 M33

I currently have 3.52 M33 FW. I screwed up and deleted the updater file before I installed the M33-4 update. Now it wont let me update to M33-4 So I am wondering how to just downgrade back to 1.50 so I can just start over.

Uhh you could just reflash your psp to 3.40oe-a and work your way back up. (worked for me when I made screw ups)

or pandora battery

thats weird that it wont let you update now.

No no, once at 3.52 M33 you can update to 3.52 M33-4 with this file Just copy/paste the update file over to PSP. You might not be able to run the update file since the update file is in your 'GAME' folder, and when you install 3.52 M33, your kernel mode for the 'GAME' folder is set at 3.52, so you'll either have to change that to 1.50 or set the update file in your GAME150 folder.

o i see what u mean, i thought he was saying that he couldnt update now because he messed it up during the process of upgrading...

ya adventwolf is right
