I think I may have bought the wrong sop8 chip socket as attached because it's the 150mil version but my bios chip doesn't seem to fit in it causing my ch341a to produce ff and ffff when trying to detec. do I need the 200mil? also the chip I have is 25q128a 13eco 99chn 42005 and is 8 pin what is the more reliable software that will have this chip number in its database that actually works or confirmed working with a hp 850 g1? I have about 300 of these laptops to work on.
yes you need 200 mil, and use one of these two software.

No, it's not. Use 7-Zip.

Use uefitool NE alpha 56. There will be EfiSystemNvDataFvGuid under BIOS region. There you will find VSS2 store.

Since 840G3 needs soldering to read/write, I still think there might have been a problem with your soldering.

And when you use dumps from other people and there is no display right away, you need to wait 15 seconds or maybe up to a minute. Dirty ME region causes this wait time.
Is there any solution to decrease the wait time ?
I have the same problem
and what is the VSS2
with editing this section can I remove the password from hp zbook bios

hi everyone, can someone make me a clean new bios for my hp 850 g1.

I have attached the serial number and a short video of my issue.

I do not have a valid copy of my original dump so hopefully someone can post back with a new bios bin file I can flash back into this bios chip. 🙏

Default Re: HP BIOS unlock tool

this is the serial number and part number detected using the hp manufacturing software for my hp elitebook 850 g1

serial number is 5CG44240HY
part number is GS267UP

if someone can help me with a new bios file that i can flash back to my bios that would be amazing and very much appreciated.

i have taken the chip 25aq128a eco13 off the motherboard no problem and i plan to erase, confirm erase and then flash the new bios once i have it.

initially the laptop had administrator password which was unknown and the guy who has it before me corrupted the bios with a bad flash and did not keep good dumps of the old bios so now i have no bios to work with.

Use the forum search ,look for a 850 G1 with clean ME firmware, flash it ,then use HP BCU/Wndmifit to enter the DMI information.

@peste @SMDFlea would any be able to help with the hp elitebook 850 g1 ?

firstly I do not have any backups of my dump bin file because I had no choice but to flash a cleanme bin file and the laptop boots fine apart from the mud data is not valid while mpm is locked.

I do not know how to get rid of this error message but at least I am now making progress can anyone assist with step by step what to do now?

thank you in advance.

I have an 8570w with, apparently, a write protected BIOS and password.
It appears that the only way to reset the BIOS is by desoldering the BIOS chip from the motherboard, reprogramming it and then resoldering it ?

Hi, do you know if you need to unlock both BIOS on a 1040 G2? I am not getting any display and flashing Cap and Scroll keys when I only unlocked the 25q128fvsq BIOS chip. Thank you for all your time and support.
