The most popular developer community, CyanogenMod has released Android 7.1 Nougat based CyanogenMod 14.1 custom ROM (Nightly) for a new set of devices, which includes, BQ Aquaris M5, HTC One M8, LG G3 Beat, LG G3 S and Nexus 5. Very likely, these devices will not get the official Android Nougat update from manufactures, however users can still enjoy the latest Android versions on their device with CM14.1.
Android 7.1 Nougat based CyanogenMod 14.1 custom ROM has already been available for a wide range of devices, but the ROM status is still in nightly. It means, not all features, especially CyanogenMod specific features like Theme Engine, are not yet available. In addition, it contains several bugs that are not yet identified and you will face stability and performance issue.
Current set of devices getting CyanogenMod 14.1 custom ROM includes:
BQ Aquaris M5 (small)
HTC One M8 Dual SIM (M8D)
LG G3 Beat (jagnm)
LG G3 S (jag3gds)
Nexus 5 (hammerhead)
Interested, tech-savvy users can download the CM14.1 Nightly build and flash via TWRP custom recovery. Note that your TWRP recovery should be the latest version (version 3.0…) or else you may end up with errors.
After flashing CM14.1, you should also flash Gapps package (Google apps) to get full access to the Play store and other Google services. Because Google apps are not permitted to be distributed as part of custom ROMs like CyanogenMod, you need to download the compatible Gapps package separately and flash via custom recovery.
If you are facing issue finding a suitable Gapps package for your device’s architecture and Android version (here Android 7.1 Nougat), the ‘Open GApps’ app solves these problems by helping you find and update correct Gapps package.
