View Full Version : Custom Firmware 4.01 m33-2 to original firmware

July 12th, 2008, 04:04
Well, I installed the 1.50 add on for 4.01 m33-2 but when I went in to recovery and tried to install an original firmware I got the error (80020148) and it wouldn't install. Can I just update straight to the original 4.01 from 4.01 m33-2 or will it mess things up?'

Edit: well I read that firmware 3.71 m33+ will take any sony official firmware, but when I went to update it to 4.01 it says I already have it installed. Any help with the recovery error would be greatly appreciated. I need to change it to an original firmware to sell it.
