Re: HP EliteBook 845 G7 BIOS Pass
hello again. today i finally managed to read both chips properly.
at first i tried to read and create backups without desoldering the chips with a selfmade probe made out of wires and pogo pins. but with no luck. everytime different results when comparing the backups. reason was that i´m a bit afraid of destroying the board/chips when de- and resoldering the chips over and over again. hope that someone can remove password from attached files and it works on first try.

@sharp
Thanks for your answer and sorry for the late reply, but i didnot have much time past weeks.
Having the second chip on the lower side of the board, i read on threads about other models but because of no time i wasn´t able to have a look at. today i took the time and unscrewed the board.
But as you can see on the pictures added, i have two winbonds (both 256Mbit) on my board. So how do you know that the MX25L25673G was the right one to chose on your board???

HP EliteBook 845 G7 BIOS Pass
Hi,
i have read many post on google and here about bios pass removal from various hp models but i couldn´t find any information about a HP Elitebook 845 G7
i found the bios chip on the board. it is a [B]winbond 25Q256JVEN[/B]
i don´t have a dump right now because i don´t have the correct programmer.
but before ordering a programmer i want to ask about the procedur.
at first i will have to order a TL866II PLUS and create a dump from the winbond.
but after that? will the HPUnlocker be able to remove the password?...Last edited by pnilip; 03-04-2021, 06:02 PM. -
