Advanced users may check out our following guide to manually installing TeamUB ROM featuring Android 5.1.1 on Galaxy S4. Note that this custom release is for the LTE model of Galaxy S4 I9505.

Points to remember

  • Before following the installation guide, create a backup of all important data on the phone using custom recovery.
  • Enable USB Debugging on the phone to connect it with the computer and use Android SDK with it. Navigate to Settings>> About phone. Tap on Build Number several times until a message appears saying 'You are now a Developer.' Now enable USB Debugging Mode by navigating to Settings>> Developer Options.
  • The Galaxy S4 should have above 80% battery charge to avoid power-off during the process, which could damage the device.
  • The phone should be rooted with the latest recovery system pre-installed.
  • As the TeamUB ROM is in the development stage, bugs are highly likely.
  • The TeamUB ROM works with Galaxy S4 LTE I9505 and applying this on any other variant might brick the device.
  • After flashing the ROM, if the device gets stuck on the booting animation or experiences boot loop then perform wipe cache partition and wipe dalvik cache for a few times before rebooting the device.
  • Once the ROM is installed, users are advised to give 10 minutes to the ROM after the device boots up for the first time for better user experience.
