I haven't gotten a serial cable hooked up yet, but I tried with
another AD7200 router that is running stock firmware version 1.0.10
and was not able to upload OpenWrt to it either. Its web interface
gives the error "Invalid file type." When started with the reset
button held down, it looks for a file named
ArcherC2600_1.0_tp_recovery.bin on TFTP, but again, the file transfers
and then the device simply reboots back into its stock firmware.
