Samsung Galaxy Nexus will no longer receive OTA updates due to hardware limitations. Thus, if you don’t want to get stuck on an older version of Android OS, I recommend you to start considering custom ROMs. Well, if you do want to try something new for your Galaxy Nexus, then I have something really great for you: a new custom ROM that is based on Android 5.1 Lollipop firmware. So, what do you say, are you ready to take your Nexus device to a higher level of performances and to latest Android built?
So, if you want to resume this step by step guide, then learn that those of xda-developers just released the new Euphoria OS, a custom ROM that has been customized and optimized for your Samsung Galaxy Nexus. The best is that Euphoria OS is based on AOSP Android 5.1 Lollipop firmware, which in a few words means that you can now easily and safely update your phone to latest Android software and enjoy the latest features, apps and capabilities that are available on the market.
However, the ROM is still under development so there might be issued bugs, lags and other software related problems. Up until now, users reported problems with the Ambient Display, with GPS, Touch control when phone is charging and several other minor issues. Anyway, the devs will soon resolve all these bugs and eventually you will be able to test a stable and smooth Android 5.1 Lollipop system on your own Samsung Galaxy Nexus – for further info don’t hesitate and check this page.
Now, if you still want to complete this update operation and flash Euphoria custom ROM on your Galaxy Nexus for enjoying Android 5.1 Lollipop OS, keep in mind that you are about to use an unofficial Android update that isn’t coming straight from Google. This is a ported Lollipop OS that has been modified in order to be able to embrace your Galaxy Nexus. Thus, due to same reasons, now you will lose the warranty of your device. Moreover, because of the same details, this custom ROM can be installed on your phone, only if you previously complete the following tasks:
Root your smartphone if you want to update to Android 5.1 Lollipop OS – the Euphoria custom ROM can be flashed only on an unlocked Samsung Galaxy Nexus (that’s happening when discussing about unofficial Android updates, so it is like a default operation). After ensuring root access, install a custom recovery image on your phone. It will be important to complete this task as the update process will be applied through the same software – I recommend you to use CWM or TWRP recovery.
Finally, before heading towards the guidelines from below, backup your Galaxy Nexus in order to save your personal data, info and accounts. Don’t skip this operation because during the installation process, a hard reset will be implied; also you will have to clear cache, thus you will basically lose everything that’s saved on the internal storage memory. Therefore, don’t hesitate and use backup and restore apps in order to temporarily save everything that you might use afterwards (you can use a cloud storage platform in order to ease your work).
Save the current ROM that is featured on your Galaxy Nexus. As mentioned, this Lollipop custom ROM is still coming with various software problems, so a backup solution should be ensured. Therefore, just complete a Nandroid backup for saving and restoring (if that’s needed) the stock Android OS that powers your device.
A computer must be used as the update package and other files must be downloaded on such a device. Also, in order to make things work without experiencing problems, you should temporarily disable or turn off any antivirus-like programs – the security tools can interfere with your work. Moreover, on your Nexus USB debugging must be enabled – for doing so you first have to gain developer rights (just tap several times on built number) and then you need to head towards “menu – settings – developer options”.
It is important to charge your smartphone before starting to apply the steps from below. You see, if your handset will get turned off while you try to flash the Android 5.1 Lollipop firmware, your phone might get bricked – if something similar happens, don’t hesitate and learn how to manually fix bricked Android devices.
