Hi guru's, hope you can help me,
I have here devices (RMAs) based on a HLK 7628N, running OpenWRT19.07 (custom image).
They appear to be having boot issues: when connected to the serial console, trying to access the response is "Failed to execut". (full output below)
I am able to enter fail-safe mode but trying to recover following instructions (https://openwrt.org/docs/guide-ser/troubleshooting/failsafe_and_factory_reset) are futile:
- Soft factory reset: firstboot && reboot now → No effect
- Hard factory reset: umount /overlay && jffs2reset && reboot now → no effect
- Hard factory reset: dd if=/dev/zero of=/dev/loop0 bs=1M; reboot → no effect
Basically I have two questions:
- Is it possible to recover (and how)?
- What could have caused this? (the RMAs did pass all the factory tests)
With kind regards,
Output from the console:
