    is your usb device formatted in FAT32 ? the two files comes into the root of the usb drive... z.b. k:\PS3UPDAT.pup K:\lvl2diag... put it in the rightest usb slot, to the bluray drive.

    You need to load the usb with ONLY the second Lv2diag.self to get it out of factory service mode.

    Same for me. Just bought a PS3 320GB 2500GB FW3.50 in Japan and also I cannot downgrade with this method (using Rockbox and a iPod Mini 2G). After getting into service mode and trying to apply the firmware of 3.41 modded, the HDD is active for 20 seconds then stops and the Green Light starts linking. Very sad, as I bought the PS3 2500 after reading everywhere that all FW3.50 and CECH 25XX systems could be downgraded.
