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
