Announcement from gekkehenkie11: Original Cm12 for the Note 4
CyanogenMod is a free, community built distribution of Android which greatly extends the capabilities of your phone.

#include <std_disclaimer.h>
 * Your warranty is now void.
 * I am not responsible for bricked devices, dead SD cards,
 * thermonuclear war, or you getting fired because the alarm app failed. Please
 * do some research if you have any concerns about features included in this ROM
 * before flashing it! YOU are choosing to make these modifications, and if
 * you point the finger at me for messing up your device, I will laugh at you.
I'm not associated with Cyanogenmod at all and most definitely not on their paylist. Just a hobbyist.


How to Install
* For 910F: Use TWRP for trltexx:
* For 910G: Use TRWPR for trltedt:
(I suggest to download the .img and flash that recovery image with the tool 'flashify' )

After that, flash the Gapps of your choice BUT MAKE SURE THEY ARE LOLLIPOP GAPPS !! And make sure the version is compatible with the Android version of the ROM (current version: Android 5.1.1)

If you come from Touchwiz, make sure to do a factory reset and wipe Dalvik cache.

The ROM is rooted already ! You just need to enable it, which can be done in the developer options. If you don't know how to see developer options:

Again, this is very important: it is rooted already DO NOT ROOT IT YOURSELF !!! If you re-root the ROM with for example chainfire, you can expect all kinds of issue's and problems.


Q: Help I can't install it, my recovery says "this is for trltexx but you are on trlte".
A: Use the correct recovery like pointed out above

Q: Do I need to factory reset/wipe everything when I flash a new nightly ?
A: If you were previously on CM12 I think you should be fine. However I suggest to always wipe cache and dalvik cache, if you only wipe the cache you ensure the system is not using old
stuff. If you however are experiencing problems that no one else seems to experience, a full factory reset might be an idea.

Q: Should I flash gapps every time I flash a new nightly ?
A: No, only the first time you need to flash gapps.

Q: Does this work for 910C, 910U, 910T or whatever other variant ?
A: No. This ROM is only for 910F and 910G. Some other Snapdragons like the 910T have a ROM out, but check those forums. Exynos users like 910C are still out of luck although someone is working on a very early alpha ROM for it:

Q: I want a cooler device (or more performance).
A: You can lower the throttle temp (cooler device) or increase it (more performance) with for example Faux clock or with this free app:

Q: Help my phone wont go into deepsleep.
A: This could be anything. To find out what's keeping your phone awake I wrote this small tutorial:

Q: My phone sleeps well but still is draining too much battery
A: In your wifi settings in the top right corner you can pull down a menu. Click advanced and mare sure you have 'scanning always available' disabled. And then there are the usual things like in settings/accounts disable syncing for your accounts, don't enable any hardware features you don't use etc.

Q: Can I use a custom kernel with CM12 ?
A: Some might work. However we optimize things in the CM12 kernel specifically for CM12, so flashing a custom kernel might cause problems. So if you are on a custom kernel and reporting a problem with CM12, at least ALWAYS report that you've flashed a custom kernel when posting about some problem you are experiencing !

Q: Does the S-pen work ?
A: Yes, the S-pen works right out of the box on Cm12, including hovering. If you're a heavy s-pen user and want functionality like for example making a cropped screenshot (just like in Touchwiz) you can enable that with a 3rd party app like:

Q: Can I control display parameters like Contrast and Saturation ?
A: Yes our kernel supports this app to do that:

Q: Can I set change the display modes, like in Touchwiz ?
A: Yes I wrote an app for that, MDNIE tuner:!uFwCAT7Z!qFzF9_...sKtLtWrazdQt5I

Q: How can I do 60/120 hz video recording ?

Q: What bootloader and/or modem should I be on ?
A: For 910F:Since the kernel is currently based on BOB4, I'd suggest to have both the bootloader and modem BOB4 too. You can download flashable odin files for those 2 here:
For 910G: Dont know exactly, probably a bootloader from december would be best.

*Known issue's:
* Google camera sometimes doenst close correctly on CM12-1 and then will yield a 'cant connect to camera', I'd suggest not to use Google camera. All other cam apps work fine.
* LTE can lose connection in some countries (Finland ?)

CM12 Known issue's (not specific to the note 4)
* Ringtones only work from internal SD card (not external sd card)
* Hardware encryption not functionally
* Fingerprint sensor not integrated just yet.

A special thank you to @slayher and @fattire, who not only were the pioneers for CM12 on the Note 4 but also helped me out countless times with problems I've ran into, both with the code and with GIT. Without their work and help we would be nowhere.

Enjoy !

So here we go on with official nightly's @gekkehenkie11. You made it possible to keep this phone longer than 2 months. That's almost a new record for me. So I did settle. And on cm. But with a better camera. Congratulations.
