Connecting to a Linksys WRT160N router via USB (JTAG)?

Question

Iron

Good day. Thanks in advance for your time.
Equipment: Linksys WRT160N V3 - hereinafter referred to as a router.
The essence of the problem:
Preamble - I flashed the router from dd-wrt to a new firmware (Tomato), cut off the electricity during the installation of the update. The router stopped loading, from special signals - the power on lamp flashes 5-6 times and silence, but when connected via LAN (1,2,3,4), the corresponding indicator lights up. 30/30/30 recovery doesn't work. When connected to a computer, the router is not detected (there is no answer to the ping).
What was tried:
1. Completely read and tried all the information from ( mirwifi.org/index.php?option=com_fireboard&Itemid=...0 results, the topic discusses a router of a newer version.
2. I decided to connect via the JTAG interface ( https://wiki.openwrt.org/toh/linksys/wrt160n#jtag) took the wire from the old Sony, connected it to the corresponding elements. When connected via USB, it is defined as an unknown device, I installed drivers from sony, nokia, it does not show signs of life, the connection is impossible, as the com port is not detected.
Has anyone encountered this problem? Or does anyone have any ideas or suggestions on what to try?

Answer 1

took the wire from the old Sony

It's not JTAG, it's TTL. These are different interfaces. Your router must have Serial. This is the same COM, only TTL levels are used. Try connecting a cable to it. If the bootloader is not killed, then there is a chance.
