Hello, I only have one bios on the board, it is 32mb, this is the original one.
hp probook 450 g8
Buildid:20wwr3BT601#SABE#DABE
27J69EA#ABE
BIOS: 25Q256JVEQ 3.3v
SN: 5CD0518SR5
I would like to have a clean bios or remove the password.
Thank you!!!

I have removed the bios attachment, you have already posted it twice in this thread, there is no need to post it again. There IS another chip on the board, and its 32MB, find it,look under the plastic ,look everywhere.look for SOP8 or WSON8 chips .

You were asked to post both files https://www.badcaps.net/forum/troubl...31#post3546731

You have only posted the main bios, there is another chip , not sure if thats also 32MB or 16MB, but there is one somewhere on the board, maybe on the other side, when you find it post the backup.

I have 3 Elitedesk 800 G6 SFF PC with password locked BIOS.

Product Number (same for all 3): 8YM57AV
Serial Numbers: CZC1239T57
CZC1239T5L
CZC1239T3X

The boards are all the same revision (Cersei Rev A)

There are two chips near the BIOS markings (Images Attached):

8 pin Giga Device 25B127DSIG
16 pin 25B256DFIG

I have a programmer on order, it only has 8 pin test leads.

Can you confirm the 8 pin 25B127DSIG is the chip of interest to RCUnlocker and that the tool works with this model of computer?

Thank you.

[GeminisK]

Try

I will try tomorrow, thanks!

Hello, I am trying to unlock an Elitebook 745 G6 with AMD cpu and dis not succeed si far. I know i missed one step may be, i dis not erase the 16mb chip before reprogramming it.

BUt i am wondering also on the quality of m'y reading because rcunlock works well on my file but doesn't display any information like model and serial number. Is that a potential issue ?

Here is attached m'y dumped file before patching.

It's not a problem if it doesn't show the DMI information.

hi. were you able to get the system to turn on in the end?

You dropped the bios in the program, you need to drag the bios over the RCUnlocker icon and release it there.

I am beginning to think it is impossible....

any solution please?

[GeminisK]

first boot press f10 apply factory defaults and restart 2nd boot reset security settings to defaults exit.
after following that flash back your original bios.
