Hello, unfortunately my original bios backup seems to be corrupted as I no longer can boot the device, Asus C433/C434 (Shyvana).
Can someone provide a bios backup of this device? (serial or codes can be removed).
Thanks.
I can get one tomorrow

Or you can extract it from a recovery image
Could you please explain how this can be done?
I downloaded recovery image 133 from the following site: https://cros.tech/device/shyvana/
Opening the binary file with 7zip shows the different partitions, but I cannot say which one might include the bios.
Use this script coreboot/util/chromeos/crosfirmware.sh at MrChromebox-2408 · MrChromebox/coreboot · GitHub
what exactly did you do / what makes you think your backup is corrupted?
flashing a generic recovery image firmware (aka shellball) should be a last resort
When initially flashing the orignal bios the device was no longer booting as expected (black screen, no visible reaction).
Today I made another try and it suddenly showed up after 10minutes of waiting, when starting again it takes around 30-60seconds to show.
There is no such delay the on the coreboot bios.

Thank you, that seemed to work. System is working correctly and booting within a few seconds now.
