CyanogenMod is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. You will need to provide your own Google Applications package (gapps). CyanogenMod does still include various hardware-specific code, which is also slowly being open-sourced anyway.

Steps to install:

(0. Install any 6.0 rom)
1. Factory reset
2. Make sure you format /system and /data to ext4 for the install
2. Install ROM zip, you will get a warning about partition size change of system if its the first time you flash, just flash it a second time to confirm the change, this will erase your data partition!
3. Please do NOT install Gapps (you can still do it, but at your risks)
4. Reboot
5. Wait for a long time

Known Bugs:
- First boot is slow
- RIL sudden crash (?)
- Webkit render issues with the latest cm14.1. It will be fixed in the next build.
- CM's FileManager is bugged

Features:
- Stock Cyanogenmod 14.0
- Dirty CoW patched kernel (anyone cares ?)
- kernel built with GCC 6.2.1 with -03
- F2fs support on /data but not on /system
- Bigmem enabled (no cma for now)
- sdcardfs support to come someday
- Zram enabled

Please note that this rom is not ready for daily usage yet, it's an alpha.

FAQ & tips :

Where is SuperSU ?

You don't need to flash SuperSU, just enable it under the Developer options.

How to change Bigmem modes ?

You can change it in advanced parameters>Bigmem

What are the best schedulers/governors/...

That's up to you, personaly, I like the combinaison of smartassV2 and bfq.

But ... how to change them ???

You can use Kernel Adiutor or any other app like that.

When will you release the next build ?

Don't ask for ETA ..... and wait.

Something isn't working, please fix it, please PLEASE

Logcat. No logcat == no fix.
If you don't know how to logcat properly, read this.

My phone is bootlooping ,what can I do ?

Pull battery and restart. Also don't forget to do a factory reset before flashing this rom.

Can you add X feature on your rom ?

No. I wont add additional features, this is stock cm. The only thing I might add is signature spoofing support.

Here are a few additional tips to get the most of this rom :
  • Format /data in f2fs in TWRP
  • OC your cpu if it can handle it
  • Use Bigmem
  • Don't install unnecessary apps
  • Remove apps from startup
  • (Wait for the next build)

Ok, just tested it. Was compared with AOSP 7 from x-racer99.
Seems CM14 more laggy in games. Not so smooth like an AOSP. But problem probably is not in the kernel. Cause i was also use x-racer99 kernel on your CM14 rom. Look at this videos with Mega Jump game:
https://youtu.be/ueyjuPu3BgA AOSP rom by x-racer99
https://youtu.be/FWbCNKZdAdE Cyanogenmod 14 rom with x-racer99 kernel.

Second video is not so smooth with a lot of jerks. May be problem in low memory killer settings, or GFX drivers, or V-Sync, or build.prop tweaks, i do not know.

Also i prefer CMC instead Voodoo Color. Because VoodooColor have two bugs since android 2.x.x. It is yellowish tint of all screen (CMC have more right white balance) and green bug on low backlight with high gamma settings, look at this video:

Thanks for the feedback, I guess that's related to various properties in build.prop. I will experiement a bit to see if I can improve this.

About CMC, you can tweak voodoo by yourself, but yeah if many people want me to switch to CMC, I will do it.

You can just download Subway Surfer from market or another place and try to make run this game more smoother. Some times Subway Surfer have bad responce on touch and can hung up after long play. Also can try this on Mega Jump or other dynamic game.
Thank you!

Ok, one question. I know it takes forever on the first boot, but, how long does it take? I've been waiting almost 45 minutes for it...
