Recently I installed the latest OpenWrt firmware (18.06.2 squashfs sysupgrade) onto my router, not keeping the settings. The previous firmware being OpenWrt Attitude Adjustment 19.02 I believe. I made sure the checksums matched and now I'm unable to access the web interface or the internet. I'm not sure whether it's bricked or not, or what I should do next.
The router still turns on, with a flashing power led. When trying to access the web interface, I briefly get a black screen with a luci link and after a few seconds I get redirected to 192.168.2.1/cgi-bin/luci, which is unavailable.
The LAN still works as I'm able to RDP to another computer on the same network. Pinging the router does not work, also trying to SSH using Putty does not work either. Trying to hard reset or failsafe using the reset button on the back of the router does not seem to do anything either.
I'm at a loss, any help would be appreciated!
(sorry if this is the wrong section for this kind of problem)
