Steps to install Android 5.1.1 Lollipop CM12.1 on Galaxy A5:

  • Depending upon your device model download the zip package files on your PC. Do not extract them.
  • Then using USB data cable connect your phone to PC, enable mass storage mode and transfer the zip files on your phones internal/external storage.
  • Safely disconnect your device from PC & switch it off completely until it vibrates. Now you need to boot your device into TWRP recovery mode. The same can be done by pressing & holding Volume up + Home button (middle button) + Power button together till you land into TWRP recovery.
  • Firstly, take Nandroid backup of your current ROM.
  • Next you need to wipe the data/cache present on your device. So press back button to return to main menu of TWRP recovery and select the Wipe option. On the next screen select the dalvik cache, system, data, cache and swipe to start the wiping process.
  • This step will clear all the data & caches from your phones memory. Hence, a backup of entire data must be done before implementing this step.
  • Let’s flash the Android 5.1.1 Lollipop based CM 12.1 ROM now.
  • Press back button to return to main menu and select the Install option. This will show you all the files present on your phones memory.
  • Just navigate to the Android 5.1.1 Lollipop based Cyanogenmod 12.1 custom ROM and select it. On the next screen just swipe to start the actual flashing process. Be patient and wait for the process to complete.
  • After completion, you’ll see a message saying successful on the screen.
  • Similarly, flash the Google Apps (containing Google Play Store, Maps, Gmail, etc.) and the SuperSU zip files as you’ve flashed this Cyanogenmod 12.1 custom ROM. Do not wipe anything after flashing it.
  • Everything completes here, just restart your Galaxy A5 by selecting the Reboot option present on the TWRP recovery mode itself. This first boot will take more time to start than usual.
  • If you want to restore back your previous Rom, then you can do that by going back to the TWRP recovery and selecting Restore option. Then select the saved ROM you want to restore.
