I have recently bought the AVM FRITZ!Repeater 1200 and successfully installed the stable 21.02 according to the device page instructions (https://openwrt.org/toh/avm/avm_fritz_repeater_1200).
However I had issues with the performance when using mesh.
Therefore I wanted to check out if WDS might be better with my setup as of now.
WDS is broken with the stable 21.02 (WDS Configuration on 21.02 - #27 by chadneufeld) and I therefore decided to flash 21.02 rc3 and keep the data.
Afterwards the devide was responding very slowly (via webportal and sssh) and I decided to perform a soft reset.
Since then I can't access the device via ssh nor web gui and when pinging 192.168.1.1 I can see that some packages are dropped, while the higher percentage pings back.
I believe I might have run into this bug: https://github.com/openwrt/openwrt/commit/f9d18281051c894eacd40f10c10b430c6c9082ad
I have tried the following things: in failsafe it does not respons at all to pings to 192.168.1.1 (could it have a different ip?)
I can get it to boot the u-boot (first step of the instruction), but it then doesn't wait for the new image in tftp, but instead boots the broken image again.
I have additionally tried the AVM recovery tool, but that failed to detect the device every time.
How and when in the boot process can I get it to load another image from tftp in order to unbrick the device?
Thanks in advance
