RCUnlocker

[peste]

Hi, I tried HP Unlocker utilities, flashed it, put the chip back, now the charging indicator is blinking. I tried RCUnlocker, a window opens with the message "missing". Please help,
Model: HP Probook 450 G3
Board: DAX63CMB6C0 rev: C
Serial number: 5CD6228XLD

half the posted content is empty...
The bios chip must be unsoldered from the board before writing or reading..
do not use the clip, you may have errors..if you do not have anything to unsolder it with,
solder wires between the programmer and the bios chip..

here is a video for example..https://www.youtube.com/watch?v=DWWi...nnel=ThisIsHow

Can someone help me and tell me how to unlock the BIOS password for an HP 12th generation laptop, such as the 840g9?

Attach your original dump bios.

try it like this..

Hi . Thanks for the reply.

The program returned an error message but I still resoldered the unlock bios chip to the motherboard and it works without any issues.. Probably just a compatibility issues with Windows..
Anyway thanks again..

Hello, I've now desoldered the chip, read the firmware, created the unlocked.bin using RCUnlocker, and flashed it again. Unfortunately, the laptop won't boot anymore.

I then removed the chip and flashed the backup bin, and it works again. Can anyone tell me if the unlocked.bin is correct?

Or can you create a working .bin for me?

Thank you very much!

the unlocked file is ok...probably the solder joints on the bios chip were not ok...or the chip was written with errors...try again..

Hi, thanks for the quick reply. I noticed, I was just about to delete my request. The pliers don't want to stay on the IC properly...

The bios posted is blank, it's normal that you couldn't do anything.

The bios chip must be unsoldered from the board before writing or reading..

Re: RCUnlocker

Clear main bios VSS region and later add SN etc back in bios.
