Re: HP Elitebook 820 G1 - Still BIOS password after flash

Here is the main board. The bios is the one upper mid left of the copper ring. There is a chip with same package just below the battery connector.

But even if i identify the ec i dont have a dump for that :/

What can i do?

I reflashed the Winbond chip using the HP Elitebook 820 G1 file.

Flashing was no problem but it still tells me:

"USER ID: BIOS Administrator
Enter Password"

I cant get in

Try it https://bios-pw.org/

U365: W25Q128 = 16MB
U366: W25Q16 = 2MB

U365: Detected as "M25P20S" by the CH341A software.
I suspect its fried since i accidently put it in the wrong direction in the programmer...There was a green dot in the corner which i was thinking was the direction mark...
But its marked 25Q12...cant read it completely because of the green dot...

Now i need to scavenge a W25Q128 chip, i guess i just order one

On top of that when i cleaned of the flux from the board a microscopic smd resistor/diode just popped of the board... cold solder...
I managed to solder it back by using hot air but its so small that i cant even see if the solder is ok or not.

When it goes wrong it really goes wrong

Re: HP Elitebook 820 G1 - Still BIOS password after flash

Well i took a W25Q128 from another defect board i have.

So flashing both U365 and U366 was done using the files from "rioreno".

Now the computer wont even boot and i dont know if its the wrong programming to the chips or if i could not resolder the smd resistor/diode.
(i guess its a 0402, really small)

Thank you all for the help i really wanted this to work.

Even bought a new screen for it since the old one was broken :/

To program this chip you use a clamp or desolder it and put them on programmer adaptor ? checks if all components ,around those chips, are in place.

Re: HP Elitebook 820 G1 - Still BIOS password after flash

Hi, I have Elitebook 820 G1 acting weird, it shuts off after few seconds, sometimes I managed to enter BIOS and reset it to defaults, but after restart again it turns off.
Thinking maybe it's BIOS problem, can anyone could help fix my BIOS dump.

Re: HP Elitebook 820 G1 - Still BIOS password after flash

Just wondering, how are you dumping and restoring the SPI? Mazzif over at MDL has a nice thread on these systems. Using a pi and flashrom one could obtain a dump, download a clean bios update and compare the two. Flashing only the VSS styles area will retain the mac address of the nic. Im actually going to be doing this later today.
