News/release from Samhain;694755:

This is how I've downgraded my FAT PSP with CF 3.71M33 to 1.50 Original FW:

* Copy the entire content of the attached file to PSP\GAME folder.
* Rename Original FW 1.50 file to UPDATE.PBP and copy it to PSP\GAME\UPDATE folder.
* In the Game menu launch "Update to X.Y.Z."
* Follow the onscreen instruction and it's done in a while.

I got a FAT PSP with motherboard prior to TA082. I've no responsibility if you damage your PSP with the above procedure.

Works on TA-079 and TA-082

This release is for use with PSPs running custom firmware ONLY. If you PSP has not already been downgraded you cannot run this!

PANDORA IS YOUR ONLY OPTION, PEOPLE.

I was able to downgrade from 3.71m33 to 1.50 with this. Just another confirmation to any doubters. Follow the instructions completely and you shouldn't have any problems.
