Update LG Nexus 5 to Android 5.0.2 Lollipop with CM12 Nightly ROM

CyanogenMod have recently announced the availability of official nightlies for the Nexus 5 while also providing an exceptional and enhanced experience over the stock firmware. CM12 Nightly can be easily installed on your LG Nexus 5 via our easy tutorial. The version you will install from our guide is set to automatically receive OTA(Over-the-air) updates.

If interested in Android 5.0.2 for other phones, check out our new Custom ROMs section. Stock has it’s reliability but we think the official CM12 Nightly proves a strong contender with added functionality.

Android 5.0.2 CM12 Nightly Lollipop ROM Details:

For those who are new to CyanogenMod, please read the following:

CyanogenMod (pronounced sigh-AN-oh-jen-mod), is a customized, aftermarket firmware distribution for several Android devices (See above for supported devices & how to install CyanogenMod on said devices). Based on the Android Open Source Project, CyanogenMod is designed to increase performance and reliability over Android-based ROMs released by vendors and carriers such as Google, T-Mobile, HTC, etc. CyanogenMod also offers a variety of features & enhancements that are not currently found in these versions of Android.

Here is a quick note for those who are going to install this release of CM12 for the very first time:

NOTE: Since this is not a final build, make sure you know that after installing this firmware update, your Android device can get FC errors, boot loops, several other bugs, apps might not work or worse, your phone might not boot. To fix, you will have to reinstall stock firmware or any other stable custom ROM.

Remember, this is not an official firmware update. This is a custom ROM, based on AOSP release of the Android 5.0.2 Lollipop.

We haven’t really found any major issues or apps that do not work with this Android 5.0.2 CM12 custom firmware.

Backup and Other Important Tips

Done with the USB drivers? Perfect. The tutorial is on the next page, but first, please take a look at the following tips and important points you need to take care of. These are important, as we don’t want anyone losing their personal data or apps:

Always backup your important data that you might need after you install a new custom ROM, an official software update or anything else. Make a backup for just in case, you never know when anything might go wrong. See below for some tips on how to backup data:

Samsung users can also back up data using Samsung KIES. If you backup data manually, you get more options what to choose from and it is very easy to move data across Android devices from different manufacturers, i.e moving Samsung Galaxy Nexus backup data to HTC One X.

If you already have a custom recovery (ClockworkMod, TWRP etc.) installed on your phone, we strongly recommend a backup using that as it creates a complete image of your existing phone set up.

A few more optional tips that you should remember:

1. Having problems connecting your Android phone to the computer? You need to enable USB debugging mode. See here: How to Enable USB Debugging — for Gingerbread, Ice Cream Sandwich, Jelly Bean and KitKat.

2. Make sure your Android device is charged up to 80-85% battery level. This might help you: How to Check Battery Percentage. Why? Because, if your phone goes off suddenly while installing a custom ROM, flashing an official firmware update or installing mods etc. — your phone might get bricked or go dead permanently. No one wants that, right?

4. Most of the tutorials and how-to guides on Team Android are for factory unlocked Android phones and tablets. We recommend NOT to try our guides if your phone is locked to a carrier, unless we have specified the carrier name or device model.

All set and ready? Good. Now, let’s proceed with the tutorial on the next page and update Nexus 5 to Android 5.0.2 CM12 Nightly Lollipop custom firmware.

  • I didn’t have any problems but want to report some issues for others who are going to follow this guide: In my CM version (Nightly 20150115) on the Nexus 5, I have the following issues:
    Camera doesn’t have HDR mode
    DIalling history shows numbers instead of the names of my contacts
    View of all open programs crashes when one program is closed

  • It might be worth noting that since the Nexus 5 doesn’t have an SD card when you wipe the data / factory reset in step 7 you will delete the install files that have been loaded onto the device.

    I got around this by sideloading the files using adb, but I was a little worried about it for a second there.
