Instal Android 5 Lollipop on Galaxy S4 With the new release of Android 5.0.1 Lollipop, we wanted to explore its new features and security enhancements. However, since this version of Android is officially limited to Nexus phones, we had to install it on a device that we own – Samsung Galaxy S4.

In Odin, press PDA button and select “openrecovery-twrp-2.8.1.0-jfltexx.tar” file.
