  SONY XPERIA ION KITKAT UPDATE INSTALLATION

Before you begin with guide instructions below, make sure your android device is adequately charged — at least 50% battery of the device.

  STEP 0: CHECK DEVICE MODEL NO.

To make sure your device is eligible with this, you must first confirm its model no. in ‘About device’ option under Settings. Another way to confirm model no. is by looking for it on the packaging box of your device. It must be LT28I/LT28H/LT28AT!

  3. Perform a full clean-up of the device (This will delete all apps and their settings and game progress). For this:
    • Select Wipe data/Factory reset, then select Yes on the next screen to confirm factory reset (screenshot).
    • Select Wipe Cache Partition, then select Yes on the next screen to confirm wiping cache.
  4. First Install the ROM file:
    • Select Install zip » Choose zip from sdcard (or external sdcard, you know where your files are) » browse to the location where you saved the file and select the ROM file. How to Flash File in CWM Recovery
  5. Now similarly flash the Gapps file.
    └ Make sure to first flash the ROM file and then the Gapps file.
  6. Reboot your device. For this, go back to the main menu of recovery and select reboot system now.

That’s all. Your phone will now reboot and it will take some time as it’ll be phone’s first boot after installing Android 4.4, be extremely excited for this!

 Note: In case your device gets bootloop (stuck at logo while rebooting), just do a factory reset (step 3) and you will be fine.

    LT28at has a locked bootloader that can’t be unlocked, so this system can’t be used with this model , please correct me if I’m wrong. I’m stuck in 4.04!!!

      Me too! At&t should let us unlock the bootloader now that it’s been such a long time.

    Works great! Fast! Three problems I’ve been facing (LT28h)
    1. BBM messenger crashes or becomes unresponsive when on network data but OK when on Wi-Fi.
    2. When I reboot the phone it says “Sim Card added – Restart your device to access mobile network”. Every time I restart I get this msg even though the sim is present. I just press back and its Ok.
    3. Once restart the data/time does not syn with network provider even though the option is selected so Whatsapp throws an error telling me to correct data/time.
    Hope to get a new rev soon that address these issues. Thanks guys. Great work! Very much appreciated.
