    i just dumped my 4.11 ps3 using a teensy++ 2.0. My question is how do i downgrade the dump to rewrite it to the console. I tried the venix downgrade program but the file fails to write to the console.

    after making sure you have valid dump OFW411 to patch OFW dump with 355 coreos, no need for any hassle anymore

    Grab NOR/NAND patches from
    • Open Flowrebuilder
    • Choose option: Patch a bytereversed NOR dump or an interleaved...
    • Load the ofw411.bin under "Select the input dump"
    • Load the "Progskeet_patch.txt into box "Patch file" (NOTE! for nand don't use norpatches.. recheck just in case)
    • Hit Execute operation
    • Flash back patched 355 coreos dump using Teensy ( COMx write 355mod.bin)
    • Release the NOR
    • Power down system the normal way
    • Reboot and it ask for "controller" UNPLUG power - insert FSM dongle etc...
