Install Android 5.0 Lollipop CyanogenMod 12 on Nexus 5

Nexus 5 has recently received the factory images of Android 5.0 Lollipop along with Nexus 4, Nexus 10 and Nexus 7, although I had a really bad experience with Nexus 4 running the Android 5.0 Lollipop, there was no Gallery app and man that was stupid, not a big reason to worry, one can always get the 3rd party apps, but seriously that was stupid.The Nexus 5, on the other hand, has a little different something in the Stock Images, you have almost all the necessary apps and stuff and the best part, that Official ROM is quite stable, fast and smooth and now CM 12 is also available for this device, like dozen of other ones. Although this is an un-official build of CyanogenMod custom ROM and contains a lot of bugs at the moment, but we hope that it will get better in the future builds.

However, the ROM is stated as a Daily Driver, but still in its beta stage, which means there will be problems in it, if you don’t want to install the Factory images but a custom ROM based on Android 5.0, why not give this one a try. In this article, we will show you How to Install Android 5.0 Lollipop CyanogenMod 12 on Nexus 5, however, if you are interested in Other ROMs, you can Visit our Custom ROMs section or you can install this ROM on your Nexus 5 by following our tutorial below. This is not an official release from anyone but a Custom ROM, you need to install a Custom Recovery on your device to install this and also your device must be rooted.Let’s go through the ROM features and early preparations and then flash this ROM.
