    under the battery what number matches this list.
    PlatformName1=3577
    PlatformName2=3578
    PlatformName3=3579
    PlatformName4=357A
    ?

    then we determine which file we use by this number
    [MULTI_FD]
    Flag=1
    FD#01=PCI,0,1,0,2C,FFFFFFFF,3577103C,03577.BIN
    FD#02=PCI,0,1,0,2C,FFFFFFFF,3578103C,03577.BIN
    FD#03=PCI,0,0,0,2C,FFFFFFFF,3579103C,03579.BIN
    FD#04=PCI,0,0,0,2C,FFFFFFFF,357A103C,03579.BIN

    heres F.23 DECrypted (rename without .DEC so it says .BIN)

    use different bios version. .. take 1 ram stick out ( might be bad)

    or u have the "BGA needs reflow"]

    folder needs C capitalized and u have it in wrong place.
    (usbstick) \Hewlett-Packard\Bios\Current and Previous ( not current or previous)

    Try to the step you said but no result. i did not know what is "BGA needs reflow".

    Can anyone send me the right BIOS file and how it will recover my BIOS? i am using a USB flash disk from Transcend and capacity is 16GB.

    thanks.

    if PHOENIXTOOL DOESNT make a .dec THEN U LIKELY DONT NEED 0 IN FRONT of file name
