This shows developers explicitly coded workarounds for this exact scenario. Device State : Bricked / boot loop
2. Problem Description
- Device State: Bricked / boot loop. No HDMI output, no LED activity (or solid LED without blinking).
- Flashing Tool Error: When using
allupgrade(Amlogic USB burning tool or custom upgrade script), the process halts at[0x30201004]or similar, with a log entry:
