How to: Install Android 5.0 Lollipop on Samsung Galaxy Nexus I9205

Samsung Galaxy Nexus I9205

Samsung Galaxy Nexus users were disappointed with the news that they will not be getting the new Android 5.0 Lollipop because the drivers are not supported by the OS. Luckily, developers have found a way to provide Android 5.0 Lollipop for he device through FML AOSP 5.0 ROM. Since this is not an official version, the OS is not stable at first, but through updates, it slowly gets better.


This article provides a step by step guide for users to install the zip file for Android 5.0 Lollipop on Samsung Galaxy Nexus. Here are some things you need to know about this OS version:

  • The Stock Camera app does not work so you need to install a third part Camera app.
  • Users should Unmount /System from TWRP Recovery’s Mount menu so that the zip files will properly flash


Before beginning the installation process, here are some notes that you have to consider:

  • This step by step guide will only work for Samsung Galaxy Nexus I9205 GSM. If you are not sure about your device model, you may check it by going to your Settings menu and clicking ‘About Device’. Using this guide for another device model may cause bricking, so if you are not a Galaxy Nexus user, do not proceed.
  • Your remaining battery percentage should not be less than 60 percent. This will prevent you from having power issues while the installation is ongoing, and therefore will prevent soft bricking of your device.
  • Backup all of your data and files to avoid losing them, including your contacts, messages, call logs, and media files. This will ensure that you will always have a copy of your data and files. If your device is already rooted, you may use Titanium Backup. If you already have an installed TWRP or CWM custom recovery, you may use Nandroid Backup.
  • Also backup your mobile’s EFS
  • Your Samsung Galaxy Nexus should be rooted
  • You need to flash TWRP or CWM custom recovery
  • Download FML-AOSP-5.0
  • Download Google Apps


Note: The methods needed to flash custom recoveries, roms and to root your phone can result in bricking your device. Rooting your device will also void the warranty and it will no longer be eligible for free device services from manufacturers or warranty providers. Be responsible and keep these in mind before you decide to proceed on your own responsibility. In case a mishap occurs, we or the device manufacturers should never be held responsible.
