#16 rootkings, Jul 12, 2015
Two bugs I caught battery and lte disappear
#17 rootkings, Jul 12, 2015
No bugs here at all.
#18 antonioblee1, Jul 12, 2015
I have it on my side I flash it correctly the battery stays on zero why is that
#19 rootkings, Jul 12, 2015
Battery stats will be fixed in next build. Not entirely sure about lte why calling.
#20 Noobified, Jul 12, 2015
What should I do about the battery problem keep it plug in or what
#21 rootkings, Jul 12, 2015
There is no problem it's just reporting zero. Go into recovery if you want to see the actual battery percent or just wait till build is finished.
#22 Noobified, Jul 12, 2015
BC if I unplug my phone it shuts down like is empty but u did a great job just little bugs
#23 rootkings, Jul 12, 2015
Went into recovery, made a backup. Flashed the zip booted but kept rebooting in start up phase.
#24 Rondeau7, Jul 12, 2015
