    So, i work at a repair shop, and i have with me here two slims. One is a CECH-2000 and the other is a CECH2500B.
    Both of these consoles displayed the wifi/bt error when attempting to update the OFW. So i first grabbed the 2000, opened it, asked my boss to solder the pins to downgrade, and flashed the console (first i made a dump and it turned out to be valid) with nofsm patches from @littlebalup 's github. After building a rebug pup with no wifi/bt patches i decided to update the console, and here's where it gets weird. The console asks for 2.76 or higher (NOT 4.82 or higher) and it ALWAYS throws error 8002F2C5 when i try to update. I have been searching online and nobody ever managed to get out of this error. what should i do? I have 2 dumps here (Before patching and after patching) and they both seem fine. If needed, i can dm the dumps for proper analysis.

    When tested with a blank HDD, the error comes different
    8002F2B5
    and sometimes
    8002F225

    haven't tried that yet. i'll probably try it tomorrow, since the console is assembled now and it's almost time to leave work

    What about simplest solutions like different USB stick, or different USB port?

    Did you rechecked dump after patching?

    ROS headers look ok? I can double check the dumps for you if u want.

    The PUP you built works on other PS3s? I've made some minvercheck pups by accident before, LOL.

    All those errors are "Error with installing Firmware update. The PUP is not recognised as valid update."
    The 8002F2C5 adds this also
    Error with installing Firmware update. The PUP is not recognised as valid update. (Can be generated by pulling the storage device with the PUP when it is still in checking stage. DANGEROUS!). Or when trying to install MinVerCheck.PUP inmediatly after an hdd replacement in PS3 models with a NOR flash

    My guess is one of the ROS is corrupted. If it was a ROS header, it would make sense why patching doesn't fix it for FW install.

    Did you try FSM Method yet? The UPDATER.log will give us a better detail of where and why it fails.

    rogero 3.7 and fsm used twice. then updated to rebug 4.82.2 no wifi/bt, to prevent hanging due to bad wifi/bt chip
