Hi again. I tried this turtorial 2 times, and it don't seem to work. All the 'text' in the TFTP program (As shown in the last picture) doesn't show. It reboots but when i go to 192.168.1.1 it is still with LEDE on it.
Afterwards, I tried flashing the firmware 'online' with 192.168.1.1, but it says "The uploaded image file does not contain a supported format. Make sure that you choose the generic image format for your platform.".
I don't know if this is a part of the problem. I downloaded "Archer_C2600_V1_160902_1475196820201r.zip"
and extracted the files to the desktop and renamed the .bin file to "archerC2600v1_tp_recovery.bin".
Now I don't know what to do.
