Google's Nexus 6 is the first Nexus smartphone to come pre-loaded with Android 5.0 Lollipop. While Google has already issued the first update to Lollipop software incorporating the Android version 5.0.1, the next update, Android 5.0.2, which is already available for Nexus 7 2012 Wi-Fi, is yet to make its way through the new Nexus smartphone.
Interested users can still update their Nexus 6 to the latest Android software 5.0.2 ahead of the official roll-out, using the customised official CyanogenMod 12 nightly, launched recently. Needless to say the CyanogenMod operating system carries the features and customisations which are unavailable in the stock Android firmware.
So if you want to try out the new CyanogenMod 12 nightly build on your Nexus 6, head over to the following installation guide.
- As the tutorial might wipe out all data of the phone, create a backup using any custom recovery.
- Enable USB Debugging Mode on the phone to connect it with the computer and use Android SDK with it. [Go to Settings>> About phone. Scroll down to Build number, Tap seven times on the build number. The Developer options under Settings should appear now. You can now enable USB debugging mode.]
- Your Nexus 6 should have above 80% of battery charge.
- The phone should be rooted and have latest version of recovery installed.
- The bootloader of the phone should be unlocked.
- The CyanogenMod 12 nightly works only with Nexus 6 codenamed Shamu. Applying these on any incorrect variant might brick the device. Verify the model number of the smartphone by navigating to Settings>> About phone>> Model number and install firmware accordingly.
- Since this is a nightly release, you might not get all the features working.
- IBTimes UK will not be held liable for any damage to the device. Installation will be completely at your risk.
How to install Android 5.0.2 on Nexus 6 using CyanogenMod 12 official ROM
