    hi guys,
    I need really your help!

    my notebook HP G62 -B35SG .
    issue: wrote wrong BIOS, now after start there is only black screen.
    after remove the battery of the BOIS for 1 hour, it shows bios error 502, and black screen again.

    i tried with key win+B, but it does not work.

    how should i do to write the original BIOS?

    Again: I really don't know much about BIOS or your notebook so I'm sorry if I cannot be of more help to you.

    what i done:
    1 download the HP Unified Extensible Firmware Interface (UEFI) Support Environment ----yes done
    2 Execute this under windows and create a HP_TOOLS UEFI boot usb stick -------yes done
    3 download the BIOS for my laptop from HP, it is a exe file, extracted it, there is a 01439.fd file,
    i copy it into Hewlett-Packard/Bios/Current, and rename it as 01439.bin, and 01439.SIG
    4 Shut down the laptop, plug the USB stick, hold win + B and power on

    nothing happend , did i do anything wrong?
