Hi, i have a C425T that can't be recovered from USB DRIVE / SDCARD (it fails always after 20-30 minutes of writing the OS)
tried with different usbdrives and different sdcards... and also using different .BIN from google repository...

the laptop was perfectly working after the repair but customer lost the passwords ..

do you have successfullly installed GalliumOS or other things (MacOS) ? can you share a dump of your BIOS after installation of coreboot (or similar? )

or are you using chromeos with stock bios

can you provide a complete dump after coreboot modifications?

Re: ASUS Chromebook c425ta-aj0054 bios

For who can be interested , here the Coreboot BIOS flashable by a programmer directly on the EEPROm (in my case: W25Q128JVPxM )
this can allow to install Linux/Windows/MacOS losing ChromeOS (not starting anymore stock OS)
