Is it possible to revive an Asus RT-N16 after a failed flashing?

Question

Good day!
After flashing the Asus RT-N16 using an auto-update from the web interface, the router became unavailable (it did not issue an address via DHCP, 0.1 and 0.0 are also unavailable). There was an attempt to enter recovery mode and use "Firmware Restoration" to upload the latest non-beta firmware (FW_RT_N16_30043763754). After the end, the utility wrote something similar to "the firmware was not completed if the indicators are lit", "Lan1" was lit and nothing more. After waiting, just in case, for about another 10 minutes, the router was rebooted. After that, it turned into a brick - when turned on, only the lan interface is lit, into which the patch cord is inserted and that's it. It does not enter the recovery mode, it does not download the firmware via tftp (tried different versions of ip-addresses). Googled, been on different forums,
Are there any ideas how to fix it, or has the device finally turned into a brick?

Answer 1

Solder a USB flash drive and sew on the programmer, or try to upload it via ttl if it is there and still working.

Answer 2

If they don’t change it under warranty, then connect to jtag via usb-ttl converter and see what’s wrong with it. Judging by the description of jtag there is https://wiki.openwrt.org/ru/toh/asus/rt-n16

Answer 3

Thanks to all.
They changed it under warranty with a comment that they can’t fix it in a timely manner :)
