IT WORKS! What I did:
- Apply sysupgrade version thru Web GUI.
- Boot to TFTP.
- Rename the oldest firmware to ArcherC6v2_tp_recovery.bin
- Made sure it transferred.
- And Voila, it rebooted on it's own
- The version was 1.0.1, so you need to flash the latest firmware on ur own by uploading it thru the web interface
