Hi Dusun Team,
We attempted to upgrade the U-Boot on the device from version 2017 to the mainline U-Boot (2025). Unfortunately, the device got bricked during the process and is no longer entering MaskROM mode, which is preventing us from flashing a new image.
Could you please advise if there’s a method to boot the device using an SD card in this situation? Also, is there any known way to force the device back into MaskROM mode so we can proceed with recovery?
Appreciate any guidance you can provide.
