system boot failure, no valid image
Critical — Immediate action required
Symptoms
- Miner does not boot past initial LED sequence
- Web interface completely inaccessible
- Miner fans spin but no hashing activity

Step-by-Step Fix
Attempt SD card recovery: download correct firmware, write to FAT32 microSD, insert, power on.
Hold IP report button while powering on to force recovery mode.
If SD recovery does not work, connect via UART serial (3.3V TTL) to access the bootloader.
From serial console, use TFTP or NFS boot to reflash the NAND/eMMC.
If the eMMC chip is physically damaged, control board replacement may be necessary.
