So I recently puchased a TP-link MR6400 for using OpenWRT.
the hardware is apparently at v3, while v1 is supported, v3 is not. i tried flashing the version for the v1, but that did not work. now the unit is "flashing on all led's".
I can still trigger u-boot tftp recovery. but i do not have the recovery image for this device. does anyone know how to get this from the tp-link firmware file?
FYI, the device will try to download "tp_recovery.bin" via tftp from 192.168.0.225, when holding the reset button for at least 5sec while powering on.
