I'm using HavocOS now. Works great.
I got mine working. I flashed the FullStock ROM from
here (bootloader only caused bootloop) and followed the rest of the instructions here.
I have noticed two problems though.
1. 'Ok Google" doesn't work, it will not stay turned on. I read earlier in the thread that this was not working for most custom ROMs. Is this still broken?
2. When using the Dialer i get mixed results with incoming/outgoing phonecalls. 80% of the time the entire GUI lags and i end up getting an error: "process system not responding". usually takes a minute or two for the dialer to initiate the phonecall. Sometimes it doesn't work at all. Incoming calls sometimes work. Other times i notice the network switch from LTE+ to H during an incoming call but nothing else happens, the dialer never pops up.
I've tried quite a few fixes. I'm either going to try a factory reset or do another clean flash. Maybe i screwed something up the first time.
Edit: This is on H872 with Gapps Full.
Edit2: I did a clean install with Gapps Full and the dialer issue was still there. Wiped and installed Gapps pico and the issue seems to be resolved. I'll install the rest of the Gapps manually and test after each to try and determine which one is causing the dialer issue.
