Re: HP Pro x2 612 G2. Flashrom new file to MX25L12873F BIOS

I did another test, before I wrote the file I did a checksum test.
Then I wrote the file to the BIOS, and immediately read the file back from the BIOS and did another checksum test. The checksums were identical.
Then I did a power on and saw the seven flashes again, I then powered of and did another read from the BIOS and did another checksum test. This time the checksum was different, can this be a problem, or is it normal that the checksum changes when you power on the computer, guess som writing to the...

Re: HP Pro x2 612 G2. Flashrom new file to MX25L12873F BIOS



I just realized that the serial number I gave you was the one from the back cover, but I just saw that there are also a serial number inside the computer
You got it correct, it's 5CG7372JZ3
I also realized that the serial number will be in the original BIOS file as well....

Re: HP Pro x2 612 G2. Flashrom new file to MX25L12873F BIOS

How did you get that serial number?
Is all of the downloadable BIOS files from HP only updates, and how did you get the attached file?

But it's still the same thing after writing the file that you sent to me, the Num Lock and Caps Lock flashing seven times when power on. But writing the BIOS file isn't any problem.

Re: HP Pro X2. Flashrom new file to MX25L12873F BIOS

This is the serial number: BDAO0100CTH8X0ABFH.
I add the backup of the original BIOS file.
This is the flashrom command that I used to write the BIOS file,
sudo ./flashrom -c "MX25L12833F/MX25L12835F/MX25L12845E/MX25L12865E/MX25L12873F" -p linux_spiev=/dev/spidev0.0,spispeed=1000 -w P86_0140.bin...

I have a problem with the BIOS for a HP Pro X2.
What I try to do is to load a new file to the MX25L12873F chip.
I'm using the RaspberryPi to read/write to the BIOS.
I connect the BIOS to the RPI as below, I have succesfully used this setup many times before.
Before I started I saved the current BIOS three times and compare the checksum, without any problems. Then I downloaded and extracted the new BIOS bin file. But the new file was smaller than the original one.
Error: Image size (9437184 B) doesn't match the expected size (16777216 B)! So i added some...

Thank you, I could flash my password locked BIOS and get it working with this one.
