    Hi all,

    Is it possible to recover the bios after a bad bios flash ?

    I installed sp51315 from HP and something went wrong,the lights goes on but only black screen.

    Can i recover the bios ?

    thanks in advance

    UPDATE:I read the forum to recover the bios,i extract sp51315 and put this on a usb stick,renamed the stick in HP_TOOLS,and did the WIN + B, but nothing happend only the light on the stick blink a fewtimes.i think i do something wrong?

    there is 3 bios in this update depending on board with graphics.. UMA or DIScrete.
    yours being NVIDIA GeForce 9600M GT - 512 MB
    http://www.cnet.com/products/hp-pav...vista-home-premium-4-gb-ram-320-gb-hdd/specs/

    is Discrete..
    now which of the 2 files D0 or D1?.. further research. right click winflash.bat and edit.. to read the function of selecting

    also i think this one works with file sometimes in root of USB or is it hp tool special folder? (researching).. unplug hdd and dvd.

    also try older version bios.

    I think the D1 file.
    Have no special folder i only renamee my usb stick,but readed that that only works when you have the tool folder on your hdd ?

    Can you tell me what files i must put onto my usb stick ?

    sorry for my questions , but this would be the first time to try to recover a bios.

    Thanks in advance

    u got wrong files ??
    sp51315 contains
    30F3F2D.FD
    30F4F2D0.FD
    30F4F2D1.FD

    FileName=30F3F2D1.FD

    you have http://ftp.hp.com/pub/softpaq/sp45001-45500/sp45082.exe

    basically try all versions with the 0 or 1 ending filename as F4.bin

    while the other model board is F3.bin with the file ending with NO 0 or 1 which i think its the UMA not DIScrete

    ok so you are trying all files (bad).
    if you have nvidia only try D0 or D1.. not sure.. but the plain no number 30F3F2D.FD is not for the nvidia type.
    that one is for other model board as F3.bin..

    yours is 30F3F2D1or0.FD rename to just F4.bin

    as soon as u boot go F10 and load defaults.. also did u try 1 memory stick at time ?? i think a mem stick might be dirty connection or bad.

    reset cmos battery didnt help after each ?
    memory sticks 1 not 2 ?

    different usb ?
    make proper folders in it and put files in current and previous?

    why change.. get ch341a and sop8 clip to flash.. find the dump of bios and ec but first make copies of yours.

    (OP)
    @LatinMcG:

    Again thank you for you time, i really appreciate.

    RESET cmos after each ? Yes
    Only one ram bank.
    Tried several usb sticks(even one i install win from)

    make proper folders in it and put files in current and previous? you mean the renaming ?

    why change.. get ch341a and sop8 clip to flash.. find the dump of bios and ec but first make copies of yours.
    No idea was this means,just check internet ch341a is a sort of usb with a holder, and sop8 clip some black plastic clip ?

    Do you have the time and the wish ofcourse, what kind of stuf i need and how to do this ?
    I completely unknown with this way of bios recovery.

    Is it not better to change the chip from the same mainbord (with a broken videocard) what i found second hand. ?
    Or is it to do (ch341a and sop8 clip to flash),for somebody who never did that before (like me)


    This is what i found
    ch341a

    Ofcourse will read the links what you gave me.
    Now for a few days out of town.
    Will let know what happens.

    Thanks again for all the help and info you gave me.

    keep the old chip or have them take a dump of bios chip.. in case serial number and such goes missing. you can read the dump from it and use nbdmitool

    EDIT: i had just done recovery on one due to screen flashing (switching to external ports on its own)
    seems board is one of those amd piece of junks.
