I can confirm this bug to. Also CPE510 HW 1.1 the same problem.

On both, CPE210 HW 1.1 and CPE510 HW 1.1, we try the same:

LuCI
LuCI reject lede-17.01.4-ar71xx-generic-cpe210-220-squashfs-factory.bin also after chorting name to firmware.bin with red infobox:
"The uploaded image file does not contain a supported format. Make sure that you choose the generic image format for your plattform"

CLI
# sysupgrade -n /tmp/firmware.bin
Image metadata not found
Invalid image magic '00366d18'
Image check 'plattform_check_image' failed.

TFTPD
Recover via TFTPD like described [[http://forum.tp-link.com/showthread.php?81684-How-to-use-firmware-recovery-function-of-Pharos-CPE|here]]:

The CPE grab the firmware (see via journald and tcpdump) and reboot, but no new firmware was flashed. System came up (or not when bricked) with old firmware and settings.
