DESCRIPTION

CyanogenMod (pronounced sigh-AN-oh-jen-mod), is a customized, aftermarket firmware distribution for several Android devices. Based on the Android Open Source Project, CyanogenMod is designed to increase performance and reliability over Android-based ROMs released by vendors and carriers such as Google, T-Mobile, HTC, Lenovo, etc. CyanogenMod also offers a variety of features & enhancements that are not currently found in these versions of Android.

FAQ:

Q: How to enable Smart cover, Dual SIM or Double tap to wake support?

A: Open 'ROM Extra Settings' from settings and enable features you like.

Q: Where are performance modes?

A: Settings -> Battery or you can add it to notification drawer in settings.

Q: I can't find developer options and performance settings, why?

A: Settings -> About phone -> Click 'Build number' several times

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

A: Settings -> Developer options -> Advanced reboot

Q: Why power button does not wake device?

A: Yes it does! You're just covering proximity sensor. There's "prevent accidential wakeup" option enabled by default.

Reporting Bugs:

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)

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.

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.

If you like our work, please consider donating some money for a new porting equipments.

Or just

few bucks for team members to have a nice cold beer after long day of coding
