Porting Firmware to TP-Link Archer C20 v5

I've followed this thread and tried out a bunch of the tp_recovery.bin files linked here, but they've all only lead to my Archer C20 V5 becoming non-responsive with just the power light on.

Here's a list of the images I tried:

Link What did it do
Official image Was downloaded, 30s later restart loop
Official image, EU version Was downloaded, 30s later restart loop
OpenWRT 19.07.03 - recovery ditto
OpenWRT 19.07.02 - recovery Was downloaded, 30s later restart loop
OpenWRT 18.06.05 - recovery Downloaded, power button on and unblinking, others off
Linaro's OpenWRT link Same as above

Can someone help me with either an OpenWRT image that I can try out to get it working, or a firmware image that I can use to return it to normal?
