Full wipe via TWRP recovery
Installed the .zip
booted up fine, no issues

Snappy and responsive

Found Issues:
app crash: Settings > Carbon Fibers > Device tunables > Vibrator intensity

Had it running for about 45 minutes now, no issues.
Texting fine
Made a call like stock Jellybean
Vibrations have made my right thigh a bit jealous of my left one

Going to flash gAPPS, test them out for a bit, then restore my data from Titanium Backup.

Thanks DM!
Will report on any other issues that come up

Very smooth no issues yet . have u found a way to incorporate hroark13 kernel with the working back cam ?...and maybe you can look Into an int2ext script for your rom to expand memory other than that super smooth and stable . good job

Its more than just the kernel.. The fixes are not stable yet, but when they are I will merge them into my kernel and tree

Yo DM, can we get an md5sum check up in here?
c971f34421225b0131282670ba9b640d Carbon-4.4.4-UNOFFICIAL.DM47021-f6mt.zip

Formatted 3 times, been having those black screens of death, etc.

I think the problem has to do with CPU frequency, as I was using Angablade's CM11 v9 for about a month now, and saw that raising the mincpu from like 384MHz to 468MHz (or something like that) virtually eliminated the black screen of dead issue (haven't had it since, can't say it's a fix, but it worked)

I was using the On Demand CPU governor, NOOP schedule for SD, 1536 cache

Flashed 2 different gApps on 3 different wipes (first 2 wipes were with a recent full gApps build from PA, last with the CM11 gApps)

Other issues that came up:
Switching to quicksettings from notification button was not functional
home and menu buttons were only functional until after gApps (Both tries)
back button acted like it was pressed twice

I think these issues are from a bad download, but I am on such a crap internet connection right now that I can't redownload.
It took me 10 minutes to even connect here!

I just tried usb. Seems to be working fine so far.


Never mind figured out the network. I just used this:

apn :fast.metropcs.com
mmsc : http://metropcs.mmsmvno.com/mms/wapenc
mcc :310
mnc :260
authentification type :None
apn type : default,mms,supl
apn protocol :ipv4

from viperdink's kk mini

The apns are present. Settings > mobile network > access point names > metropc lte
