Re: HP BIOS unlock tool

Hi
Hp850 G4
password missed
Tried to read 25Q128FV ( in-circui, without desoldering) and unblock with RCUnlocker.
After flashing unlocked bin system said that bios is updating...
After restart it said system locked, authentication failed
I tried to flash dump from here https://www.badcaps.net/forum/showpo...postcount=1008
System does not start; cooler gets up slowly, screen is black, and no reaction on pressing any buttons.
What is wrong?

Re: HP BIOS unlock tool

It starts on bios from previous post. It updated firmware of one component. And now it starts tooooo long and caps lock is blinking 5 times while starting. How to solve?

Re: HP BIOS unlock tool

I've managed. https://www.badcaps.net/forum/showpo...9&postcount=17 and https://www.badcaps.net/forum/showpo...5&postcount=22 were helpful.
In my case reflash only 25Q128FV was enough.
Thanks

Re: HP BIOS unlock tool

Hi guys!

Can uhelp me removing the bios password? After trying it myself, the laptop's data has been erased (sku, build id, etc..) and every time I turn it on I get a "system is booting in manufacturing program mode" message; after a second try, now I get an "HP Endpoint Security Controller Problem" message.

I attach the original bios and original ec bios (HP Elitebook 840 G5)

"Hello everyone,

I'm in need of assistance to unlock the BIOS password for my HP ZBook Studio G5 (Motherboard: DA0XW1MBAI1 Rev I). Unfortunately, the BIOS files I have are of sizes 32MB + 1MB, and RCunlocker doesn't seem to support the 32MB size. I would greatly appreciate any guidance or help provided.



Thank you in advance."
