AVM Fritz!Box Fon WLAN 7170 support/working image

Hi all,
I recently found my old Fritz!Box 7170 in a dusty corner of my flat. I'm wondering if I can get some help to get LEDE up and running on this router.

I've set up a github to collect all information to set it up. So far there are some very old, but working OpenWRT images on their wiki. As well as old installation guides and patches.

The images for ar7 with kernel 4.9 build fine in a virtual build environment. Unfortunately the EVA image isn't running with the Fritz!Box. Maybe someone else had better luck after all or got some tips.

Anyway, since this old router was at his time quite popular in Germany, maybe there are some more of you interested in getting this device up and running with latest LEDE.

I have tons of 7170 boxes and I'm very interested in this too.
Did you manage to get it working?

Please add any relevant findings to the devicepage https://openwrt.org/toh/avm/fritz.box.wlan.7170

Thanks!
