CM11 M7 works flawlessly... but:
- there is no default ringtone so if u wiped your /data you will hear silence when someone calls u
- there is no kernel with working usb-otg nor usb-hdmi around for this release, but DorimanX team is looking on to that.
- CM's gapps not working (not ready for 4.4.3 obviously), use pa_gapps (http://forum.xda-developers.com/show....php?t=2397942
) - in my case only micro was small enough to fit with that new huge CM
- that kitkat /storage/sdcard0 read-only issue makes lot of apps to just crash !!
Besides above it works pretty well. Wifi stable, hsdpa stable, calls/sms fine, browser fine. Can't find anything more not WAI.
At this time I'd suggest NOT flashing DorimanX on newest CM 11 M7.
If u wiped /data partition you have to recreate some default structures (eg. DCIM or camera and gallery won't work).
