I've tried Gargoyle, DD-WRT, and actual TP-Link firmware all named as `wdr4300v1_tp_recovery.bin` and noted in my ftpd logs that they are successfully downloaded after doing the reset-hold power on.
From what I can tell, it downloads it, waits 2-3 seconds and immediately reboots. Are we completely barred from firmware changes via even TFTP now?
Firmware Version: 3.14.3 Build 151104 Rel.45874n
