Bios HP 250 G7 need help

Hello everyone,

said NB recently tried a bios update (automatically?) said the owner. So I tried to flash the latest bios from HP using a repair stick.
However, it only starts during the flash process until "initialize"... - after a few seconds it switches off and stays on with pwr_led.

Bios backup file does not exist.
Serial Nr: CND93963RY

Screenshot of the label attached. Can someone help if possible with instructions or a link to it?

Thanks in advance

Re: hp 250 g7 corrupt bios

Thank you very much for the advice,
i can't write bios with with Win + b,

the tl866cs timer does not recognize me the main bios chip signed xmc qu64ah1g
but I managed to dump 8mb by checking the check id, I attach the dump,

the bid version 084AA

i think the tl866cs will give writing problems for this i am trying to use the WIN + B procedure,

I prepare the usb key and copy the bios to the current folder, I rename it 084AA.bin but it gives me error "Bios ID of Image does not match system"
you also need another 084AA.s12 file

thanks for the help

Hi, how do you manage to obtain the bid version from the bin file?? i made a dump file of my bios but i can't find the version inside.

Thanks!

Re: hp 250 g7 corrupt bios

sp100745 is a diagnostics app,that version does not include any bios. The recovery methods are listed in this HP document - https://support.hp.com/in-en/document/c02693833
There is no bios update listed on the 250 G7 drivers support page but a full bios is is included on the latest HP PC HARDWARE DIAGNOSTICS 4-IN-1 USB KEY - http://ftp.hp.com/pub/softpaq/sp1035...0/sp103655.exe
Make another key from that and run it, if you still can`t recover the bios then extract the 4-in-one key with winrar or 7zip.Look in the folder called Field,then open the BIOSCopy.csv to find your bios name in the list.All the full bios are in the BIOS folder.Flash the bios with your tl866,then you`ll need to run hp BCU bios config utility from windows, nbdmifit from UEFI or use wndmifit from windows.
HP DMI Tool NBDmiFit - https://www.badcaps.net/forum/showthread.php?t=69204

EDIT: The bios.bin isn`t in the BIOS folder even though its listed in the BIOSCopy.csv file. The bios is 084A8 ,check your bios backup to make sure its the right one. Strangely the bios is included with an earlier version of the 4-in-one key for other models but not listed in the .csv , thanks HP ! .

Bios 084A8.bin attached .
