I recently installed OpenWrt on my Archer C50 router and when an error occurred with the firmware i tried to recover the router via TFTPD methods. However following the guide i was using recovered the router using the stock firmware from TP-Links website without any modifications to it, just renaming the file, as the guide suggested.
However now the router is unresponsive and i am not able to get the router to enter recovery mode at all and only a light flashes on briefly before no lights turning on on the router. since reading more about TFTPD other guides for recovery suggested using a modified firmware file, whereby the first 512bytes of the latest firmware are removed from the file before flashing.
If this is the case, is there a way to unbrick my router now with me attempting to recovery flash the unmodified firmware on it, or is it well and truly bricked?
I've never done this, but here there is a way to do it via ssh - worth a try: Login as root via SSH on 192.168.1.1, then enter the following commands: cd /tmp wget http://http://downloads.openwrt.org/snapshots/trunk/XXX/xxx.abc sysupgrade /tmp/xxx.abc
However it appears in this case the user was still able to use the recovery mode via TFTP, something i currently cannot do anymore after trying to initaillty do it. They login to the router vias SSH after they have flashed back to factory firmware, which i cannot do via TFTP at the moment.
I was playing around with the Archer c50v3(which version do you have?) a many times and bricked it as well and its quite robust. Yours is unable to unzip the kernel i think. Can you use serial connection via the serial port directly from the pcb?
I'll be online each day to answer your questions.
