I have the original 60gb test/debug PS3 that had firmware 3.15 on it that I installed the 1.00 downgrade pup on. It really did downgrade the system to 1.00. Now I'm having this issue where no matter what debug firmware I try to upgrade to it doesn't install.
The 1.60 to 1.92 firmwares that I have will get to the install screen but then fail with invalid data type
Anything 2.00 or higher errors our during the copy process to the hard drive.
It still appears to be a debug system as the install packages is under the system settings and does work for debug packages.
What am I missing here to go to a higher firmware?
