Prolific mobile software developers Cyanogen team has released the much awaited official 5.0.1 Lollipop CM12 custom ROM to the LG's 2013 flagship smartphone Google Nexus 5 (Hammerhead) model.
Cyanogen team has confirmed that the new CM12 is Nightly version of AOSP (Android Open Project) 5.0.1 Lollipop.
Though it is the official custom ROM, 'Nightlies' version is unstable and there are some bugs, which are yet to be fixed. So, we advise our readers to go through the whole tutorial article first before going ahead with the installation.
Some features missing in the nightly version are:
- Theme Engine
- Quick Settings reorganisation and customisation
- Quick Settings Ribbon mode
- Navigation bar reorganisation and customisation
- Sound panel customisation
- Lock-screen quick unlock
Cyanogen have stated that they have completed 85% of development of stable update and promised to roll it out soon. Until then users can upgrade their device with nightly update to explore the new custom features.
Prerequisites (Things to remember before installing the CyanogenMod CM12 Nightly):
- Users are advised to update their third party add-ons to ensure compatibility
- The CM backupscript.sh in recovery will ignore and remove incompatible applications from your system partition (these are usually non-CM apps that users have opted to install). You must install a compatible app (or app pack) to regain that functionality
- You can flash CM12 nightlies directly from CM11 M12 or CM 11 nightlies (no need to wipe), provided you read and follow items 1 and 2.
- Once on CM12 nightlies, you cannot downgrade back to CM11 without wiping – if you are thinking of just exploring the release, then take a back-up of your existing installation if you want to go back to it.
- Users must install Lollipop OS compatible recovery before installing the new CM12 custom ROM.
- Though installing custom ROM improve the device's performance and UI experiences, it makes the company warranty void and they will no longer be liable to provide updates in future [users can restore warranty by flashing the device with stock-ROM].
- Make sure the device is rooted before going forward for custom ROM installation.
- Installation of custom ROM requires clearing of memory in the smartphone, so make sure to back all the data by installing Clockwork Mod (CWM) Recovery / TWRP in the smartphone.
- Users make sure they have installed USB drivers on the PC, or else your phone (Google Nexus 5) smartphone will not be recognised by the computer.
- Make sure your device has more than 80% battery, or else there is chance of smartphone getting temporarily bricked if the installation process is interrupted mid-way.
- This new CyanogenMod Android 5.0.1 Lollipop custom firmware has to be installed on the LG-Google Nexus 5 (aka Hammerhead) only; if tried on other devices, it might get bricked [To check your device model: Go to Settings >> About phone >> model number]
