I have a Samsung Galaxy S7 edge with nougat, but Installers says I have an AOSP based rom and cannot find appropriate .zip
Edit: Can someone please link me to the unofficial thread for samsung devices?
By the way, I have tested the official version on my Pixel and the Genymotion emulator, @wanam tested on OP5 and Galaxy S7.
I should probably mention that we're using SuperSU, which disables dm-verity. Without that, modifications of the /system partition might lead to boot errors on some (many?) ROMs. I had started to work on official systemless a long time ago, but never finished it because the work on the "core business" of Xposed took all my time.
