System Details

  • Device: magister
  • OS: Linux
  • Firmware Type: UEFI Full ROM
  • Firmware Version: MrChromebox-2509.3 (11/08/2025)
  • Internal storage type: eMMC

Summary of the Issue

There is no issue, i just wanted to ask, do i have to bridge the jumper pins after UEFI has already been flashed and i want to flash stock firmware instead. Also, i lost the backup file the script generated when flashing UEFI, but just the recovery image should also have it, right?

no you do not.

using stock firmware extracted from a recovery USB isn’t quite as good, and not guaranteed to work

I just did it and the recovery media firmware works good enough to get it booting
