I am new to OpenWrt and ran into a boot loop with my Archer C7 v1.1 that was very well known, but not included in the device pages.
Following the recommended recovery behaviors I entered the failsafe mode.
But just because I asked in the IRC channel I found out, that one can scp other firmware images and perform
sysupgrade -n file.bin to flash them.
As a newbie I didn't manage to find a good article that told me that is possible and it seems to me that it should be mentioned in the failsafe mode page.
But since I am new to all this and the failsafe mode page is somehow 'critical infrastructure' I do not want to include that information my self.
