Users of the older Google Nexus 5 smartphones can now flash a new VanillaAOSP custom ROM based on the Android 5.1.1 (Lollipop) OS update, on the device.
VanillaAOSP does not incorporate Google's apps and services, like the official Android 5.1.1 build, which boosts its performance in terms of multi-tasking and allows webpages to load faster.
Points to remember before flashing VanillaAOSP custom ROM on Nexus 5:
- LG-Google Nexus 5 Hammerhead should be rooted before installation of custom ROM along with having ClockworkMod Recovery.
- Back up all stored data by installing TWRP on the smartphone, as custom ROM installation clears storage.
- USB drivers need to be installed on the computer, so that the Nexus 5 is detected.
- Ensure that the handset has at least 80% battery charge to avoid bricking the device during installation.
- Installation of custom ROM nullifies warranty provided by your smartphone manufacturer. However, you can flash stock-ROM to restore warranty.
