CyanogenMod is a free, community built, aftermarket firmware distribution of Android 5.1 (Lollipop), which is designed to increase performance and reliability over stock Android for your device.

* 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. Hard. A lot.

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. Linked below is a package that has come from another Android project that restore the Google parts. CyanogenMod does still include various hardware-specific code, which is also slowly being open-sourced anyway.

All the source code for CyanogenMod is available in the CyanogenMod Github repo. And if you would like to contribute to CyanogenMod, please visit out Gerrit Code Review. You can also view the Changelog for a full list of changes & features.


We'll not support users and answer questions from users which:
- are running a custom kernel
- have flashed mods
- modified system files
- didn't follow our instructions word by word
- are unfriendly

First time installing CyanogenMod 12.1 to your Lg G3 D855, or coming from another ROM:
- Read known issues ans FAQs
- Flash one of the recovery images (CWM, TWRP)
- Copy GApps and CM12.1 ZIPs to your SDCard
- Boot into Recovery
- Flash CM12.1 zip from SDCard
- Flash GApps zip from SDCard
- DO A DATA WIPE / FACTORY RESET (otherwise your device might be stuck at boot)
- Reboot
- Don't restore system data using Titanium Backup!
- Restoring Apps + Data might cause problems and is not recommended, avoid it if possible!

Upgrading from earlier version of CyanogenMod 12.1:
- Copy CM12.1 ZIP to your SDCard
- Boot into Recovery
- Flash CM12.1 zip from SDCard
- Reboot

3G & LTE
GPS (maybe)

Sometimes it does not want to wake up from sleep (like me)

after a couple of hours worked me everything without problem.

the only thing is that I slowly throughout the system, I think it is normal for being the first version, I hope to go slowly resolving this as and when updates or exit the official version

PD: Bluetooth work ok! GearManager
