Known issues/bugs:

- Camera HDR mode does not work
- DUALSIM: DO NOT DISABLE SIM2. If SIM2 disabled, enabling is almost impossible without factory reset.
- Phone filesystem encryption reported not working
- When disabling button backlights, reboot is needed to make'em stay off (work around crappy lenovo kernel)
- FM radio not working
- DUALSIM: When sub calls set to "Ask Always" dialer may cause phone freeze sometimes
- MMS not working
- SIM2 mobile data not working
- DUAL SIM: Renaming SIM cards may cause mobile data connection loss. So do not rename SIM cards for now
- DUAL SIM: Mobile data is not always enabled before go to "Settings -> Sim cards"
Installation issues:
Some users may not be able to install this ROM due to too small (1GB) system partition.
If in doubt, It is easy to find out size of system partition.
Open RootExplorer (file manager) on your phone, navigate to /proc, and open file "partitions" as text file. The 19th or 20th partition is for /system. if it is 1048676 then the system partition is 1G，if it is 1572864,then the system partition is 1.5G.
In case of 1GB partition, you have to download llaalways's repacked ROM with 1GB system partition.
1GB ROM Download: http://pan.baidu.com/s/1kTtHG27 password：9nsc
Fix partitions: you'll need to update your phone via stock sdfuse method with file: K910_SS_S_2_040_0109_131226.qsb and then install CM12.1

Q: I don't have reboot options in power menu, why?

Reporting Bugs:
Carefully describe how to reproduce the bug, if possible.
1) Grab a logcat right after/during the problem has occurred. (Please include at least a few pages of the log, not just the last few lines, unless you know what you're doing.)
in case of modem bugs, also "logcat -b radio" is needed. If possible log must be captured all way from boot.
2) If it is a random reboot, grab /proc/last_kmsg. (Do not bother getting a logcat unless you can get it just before the reboot. A logcat after a reboot is useless)
Look for /data/anr and /data/tombstones directories for crash logs to share.
Remember to provide as much info as possible. The more info you provide, the more changes there are we can reproduce bug and possible fix it. Please also do not report known issues. The following is a useful format to follow:
What is your phone model (K910, K910L, K910e, etc..)
- ROM Version
Are you using:
- Any kind of task killer.
- Xposed
- Dual SIM.
- other modifications; Provide any additional information (observations/frequency of problem/last version it worked on/etc) as needed.
Upload logs to for example pastebin or any filesharing service and sends logs to me. With PM or email: morphic.ts@gmail.com
We have spent ernomous amount of time for porting this ROM.
All work is done in our spare time. We give this for you as free of charge.

Or just few bucks for team members to have a nice cold beer after long day of coding ![;)]()
NOTE: This is nightly beta, there might be some bugs!
ENJOY!
