Try to flash sysupgrade from [[https://downloads.lede-project.org/releases/17.01.4/targets/ar71xx/generic/lede-17.01.4-ar71xx-generic-cpe210-220-squashfs-sysupgrade.bin|here]].

LuCI let this image pass but the device do not came back after reboot.
Only the Power-LED ist on, no blinking of RSSIHIGH during boot.
On LAN or WAN is no activity. Checked by tcpdump.

Expected behavior:
System reboot in LEDE-17.01.4    

Like described in this [[https://bugs.lede-project.org/index.php?do=details&task_id=902|bug]]
it is not possible to recover via TFTP the device. It pulls the firmware but do not flash anything.
Try to recover with LEDE but also with all stock-images from tp-link website.
