Problem with TP-LINK WR941ND router on DD-WRT?

Question

linux

Good day.
Looks like I just bricked my router with a firmware not of its generation - I have v3.5, and I rounded up to 4 and put the firmware for v4.
Now my router does not respond to pings, I can not connect to it via TFTP, as advised on the dd-wrt wiki .
How else can I try to bring my piece of iron back to life?
Thanks in advance for your replies.

Answer 1

Try pressing the reset button, hold for 30 seconds, turn off the power, wait 10 seconds and, without stopping holding the reset, wait another 30 seconds. After that, you can try to push the firmware via TFTP (to be sure, you can first upload the firmware with a mark like "clear nvram")
LinkSys and Asus's come to life in this way. Of the ~ 20 routers, not a single one managed to kick to death.
In the case of a brick, it was revived in the above way.

Answer 2

By the way, check if the bootloader is alive on the router by connecting to it with a console cable. I know about a case when a person restored a router by feeding it the correct firmware through the bootloader console, converting it into HEX codes and uploading them through Hyperterminal
