Re: HP Elitebook 840 G5 W25Q256JV
I went ahead upon your confirmation. I have successfully regained access to BIOS.
Once again, thank you for your effort, knowledge and time.

Re: HP Elitebook 840 G5 W25Q256JV
Vesko356, I found the chip and got a good read, a W25Q128JV, 16MB chip hiding on the back side of the board. They really do the effort in making it as struggle as it can be.
Here is the read without any modification, and hopefully the dump containing the lock.

Here is my attempt to remove the lock, I would love to get you input whether or not I succeeded in this attempt.

And preferrable I would like to see your version of the read without my mod....Leave a comment:

Hi, I'm reaching out to seek help to unlock BIOS on my HP Elitebook 840 G5. The chip, as far as I'm concerned, and the one responsible for the BIOS password is the W25Q256JV. This is a 32MB chip. To my knowledge there are no 16MB chip on the board. If you happen to know otherwise, your comment on this is highly appriciated.

Re: HP zbook 15 g6 Bios Password
Thanks Vesko365. I was afraid that might be the case. I did compare your file against the unlock from the RCUnlocker, and they were different, allthough the RCUnlocker returned successfully as well, I have yet to actually test whether or not it would work. For the record, I'm no even close to being confident to manage what you did. Thanks again for your efforts and time providing a solution to my problem.Leave a comment:

Re: Unlock GD25B256D Gigabit serial flash
Worked like a charm. I'm curious to ask if I could have done it myself with the RCUnlocker tool, since this was a 16MB chip?
Thanks again for you effort and time.Leave a comment:

Zbook 15 G6 Unlock GD25B256D Gigabit serial flash
Hi,
I'm reaching out to seek help unlocking bios lock on my HP Zbook 15 G6. It has the GD25B256D serial flash chip from Gigabit which is a 32MB chip. Motherboard DAXW2EMBAE0 REV E.
Are there any other chips on the motherboard except from the one clearly marked "BIOS" needed in order to unlock bios?

Re: HP BIOS unlock tool
Yeah, I can imagine it might be tricky. I guess so too, relatively easiest way is to unsolder and place it in the jig.Leave a comment:

Re: HP BIOS unlock tool
Did you succeed in finding a 3d model for printing a case for wson8 chips? If not I will purchase one and copy the design and share the STL model with the forum. Feel free to share adapters that has a good reputation so we can copy something that likely will work
