Update Nexus 5 to Android 5.1.1 OptiPop Lollipop Custom ROM

Nexus 5 recently got updated to Android 5.1.1 and here is a custom rom for this device that supports Android 5.1.1 Lollipop. OptiPop is based on official LMY48B factory image. With this custom firmware you get pure AOSP experience with some custom aftermarket features like Statusbar Brightness Control and Double-Tap to Sleep. A lot of under-the-hood optimisations have also been made to make sure that the firmware stays stable, fast and smooth. If interested in Android 5.1.1 for other phones, check out our new Custom ROMs section. Stock and official firmware are always good, but custom ROMs make them better with new features and lots of system tweaks that are not otherwise possible.


This is clearly one of the advantages of rooting your Android phone (read: Benefits of Rooting an Android Device). You can update Nexus 5 to Android 5.1.1 OptiPop Lollipop custom firmware using the tutorial below.

Few more important things that you must remember before installing any custom ROMs or Official Firmwares:

  • You might face some problems in connecting your Android device to the computer. How to fix? You need to enable USB debugging mode. See here: How to Enable USB Debugging — for Gingerbread, Ice Cream Sandwich and KitKat.
  •  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?
  • Most of the tutorials and how-to guides on iDroid Horizon 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.
