Dearest all. I was able to screw up a firmware upgrade. I successfully updated to TD-W8961ND_V3_140305 and then tried to update to TD-W8961ND_V3_150707 which failed and stopped the modem from working and created an infinite boot loop.
I was able to ping 192.168.1.66 after setting the LAN to that static IP.
How do I use TFTP to send the default firmware and get my modem working again, please?
Thank you for any help,
