I tried to upgrade dd-wrt on my AC 1900 C9 V1 router and accidentally picked wrong upgrade firmware for another router. Upgrade dis go through, got the success message on the screen and then nothing. Right now router boots up and two LEDs blink very slow (Ethernet and wps). These two LEDs stay lit for few seconds and then turn off for a few and then light up again.

I tried to unbrick it using tftpd and original tp link firmware multiple times, but nothing worked. Router did ask for the firmware file, downloaded the file successfully, but didn't really do anything beyond that. The two LEDs are still slow blinking.

Any ideas?

Worst case, serial connection required, but shouldn't be necessary unless you really b0rked it.

P.S. All supported "AC1900" TP-Links are Broadcom, so I moved your topic.
