Hi
I have this HP Chromebook G5 EE with Developer mode locked no chance to disable it cause Admin has disabled it and enrolled to a foreign school. Is it possible to have a good backup for it with differing serial so that it is not enrolled, and I also have problems writing other BIOSes to this machine like earlier on a ASUS C302C. I am using a Revelprog programmer but I suspect that this programmer has problems, because the WP screw is removed and I wonder why I am not able to write other firmwares, just those that I made backup prior? The flashing goes until the end successfully, but just verification failed at the third stage (erasing, writing, verifying)
The flashchip is W25Q64FWSIG 8 MB , and the model DANL6CMB6F0 rev F

I can help, please wait and I will try to get you a clear bios as soon as possible

Hello,
any one who have this BIOS file?

Below I attach the BIOS readed with RT809H as it seems the Revelprog had some issues reading.
If you can also check and tell me if the backup was made successfully now with RT809H?

What Is Bios?
The BIOS is low-level software that is responsible for initializing the computer's hardware and providing basic instructions for the operating system to load.
The acronym BIOS means Basic Input and Output System. It is responsible for carrying out essential tasks, such as recognizing installed hardware, checking the time on the internal clock and initializing the operating system.
Without the BIOS, the computer would not be able to boot properly as it is the first software to run when the computer is turned on.

Mechanism Of BIOS In Computer Systems:
When using a notebook, you have most likely come across the word BIOS in the settings. This tool is responsible for performing a series of tasks on your computer.
The moment you turn on your PC, the BIOS identifies all the components connected to the motherboard, the information saved in the CMOS (which stores the board's configuration parameters, accessible through the Setup menu), such as which drive will be loaded first, changes the processor speed (overclock and underclock) and also checks the internal clock.
Once the BIOS confirms that everything is fine, it loads the boot from the first drive defined in the setup and then passes control to the operating system.
