HP EliteBook 845 G7 BIOS Pass

Re: HP EliteBook 845 G7 BIOS Pass

I programmed just the second BIOS chip with updated Bin files you send me, but no luck. Now what happens is the LED on the power jack blinks 5 times fast & stops & then again blinks 5 times & stops & this keeps on going in a loop till I remove the power cord. It does not turn on at all even after pressing the power ON/OFF button on the keyboard. Kindly re-check please. Before this all was working fine except for the ADMIN BIOS Password. Thanks

Check the content of the chip, did you use verification? Also check the soldering of the chip and nearby components, make sure you didn't knock of resistor or something else at the surrounding area.
Edit: also check the soldering of the other chip.

Program only this (second) chip with the attached file, the other stays as is.

Re: HP EliteBook 845 G7 BIOS Pass

if you modify the main bin (unlock) and then write it back, the ec chip sees that it has been played with, then it puts the old backup back with password back in, the newer hp you should not do the old way, this gives these problems and many errors

Re: HP EliteBook 845 G7 BIOS Pass

Hello, sorry for my english. I soldered the chips back to the board, the laptop did not start, I looked at the board again and found that the sixth pin was soldered on one of the chips. After the soldering, everything started and, lo and behold, the admin password disappeared, but the Endpoint Security Controller inscription appeared. In any case, it's better than not having access to BIOS settings. Now everything works except this warning at startup.

Re: HP EliteBook 845 G7 BIOS Pass

Today i updated my CH341A programmer (3.3v FIX). I'm using other software for read BIOS chip, but reading data absolutely identical with files read earlier.

Re: RCUnlocker

@Mijgan
Take the reading again with all batteries disconnected, including the (CMOS) and post again.

I soldered both chips and read them on CH341. Read and verify 2-3 times. All read data is identical.

Re: RCUnlocker

Hello everyone, I have an HP EliteBook 845 G7
The bios has an admin password. On the board 2 bios WINBOND 25Q256JVEN, both chips are the same in 32MB. I apply 2 bios 32mb each (under the board) + 32mb (under the cover)
Can someone help me remove the admin password?

Re: HP EliteBook 845 G7 BIOS Pass

It's confusing, so we don't need to delete the Admin password in the remaining file?

@hoaca388
There are at least three variants for the new models with EC and SPI, 32 + 32Mb.
Although the EC is usually on the top side of the board requiring removal of the PCB, unlocking by EC will always be the best option.
