I have a WNR3500L v1 netgear router
Last attempt to change the tomato firmware, no power.
The router does not respond to ping, it does not connect via a serial connection. Probably no cfe.
I have connected jtag and I have these symptoms.What to do next, how to upload cfe. What can anyone do to help?

You can try to send firmware file via serial cord and correct port on router motherboard. Debrick tutorial you have on youtube service. Probably is similar for wnr3500l v2. You must have tftp software for this operation and putty. Probably debrick v2 router is similar to v1. I have v2 one and I'm flash with serial cord with success
Thanks, I wrote that the serial connection or serial does not work. Probably the only chance by jtag but I don't know how? On the router only the green power LED is on and the wifi LED is on, I forgot to write about it.

If green led light I think your device is operating without network fumctions available. You can try to force tftp mode. Like that: https://www.youtube.com/watch?v=0K8sVuCrPt4 Alternate you can flash router with serial cord and correct software. Like that: https://www.youtube.com/watch?v=o5AOH3Jl7VA Your router is not totally bricked. I have many with bootloop and other problems and I can fully reactivation it. Your problem isn't big. You have small soft brick, because your device is operate (green led, wifi led...)

Fix procedure should be the same. Router haven't bootloop and other problems. Probably it work, but you haven't access to this device. Jtag method can be harder to use. Try two above methods to fix device.
