Past monday I've made one version based on AOSP 6.0.1 from xda
I can't test it yet, because I've only one nexus 4 and it's used on my work.
I've tried to flash but, I can't, get stuck on the begining of updater script. I think it was because I'm on TWRP and I need to change to Clock Work Recovery.
I have no time to flash it beacuse I need to travel out from home this week. All rejects should be repaired.
If some want to test, i'll put a link to my drive. It's a heavy zip about 650 Mb, I think some apk's should be removed like FM that will not work on our nexus 4 but I can't do it today..
