The system is stable and comes without major bugs or issues so you can flash the ROM for a daily use. If you have decided to do so, first of all complete the pre requisites from below and then take care of the proper update procedure.

  • First of all you need to unlock the bootloader of your Xperia Ion. The bootloader must be unlocked because the operations mentioned below can’t be completed on a locked Android device. Make sure to use a compatible tutorial for your Sony smartphone because unlocking the bootloader isn’t an official operation.
  • Then, root your Xperia Ion. Also gaining root access is essential for us as PureSlim Android 4.4 KitKat OS can be flashed only on a rooted Android device.
  • Finally, install a custom recovery image on your phone. Make sure you are flashing the latest version of CWM or TWRP recovery because the present ROM can be applied only by using the same.

  • A backup is strongly recommended because a wipe must be performed before flashing the update on your device. So, before doing anything else save everything that’s important from you – take care only of the data that is saved on the internal storage memory of your Xperia Ion. Don’t forget to make a Nandroid backup on your way as it is quite important to save the current ROM when dealing with a custom firmware.
  • Also, this is a manual installation procedure; in order to apply the steps from below you will have to use a computer, your smartphone and its USB cable.
