With this update, it looks like Sony wants to be done with updating all of its mainstream devices to the latest firmware as soon as possible and the Android 5.0 Lollipop Squad is coming to an end now. The new update brings a lot of changes on the Xperia T2 Ultra. The very first change atop of the list is the new UI, which Sony changed according to Google’s new Material Design UI. There are new multi-user and guest modes on the device now and new intelligent notifications on the lock screen. The new update carries the build number 19.3.A.0.470 and as mentioned, it is based on Android 5.0.2 Lollipop.

At the time of writing this post, only single SIM variant of the Xperia T2 Ultra is receiving this update, but we hope that the dual SIM variant’s update will follow it very soon now as well. This update has hit only few regions for now, and it sure will take quite a while to hit your region if you don’t happen to be that much lucky yet. You may want to find a different way to update your device for now, and that is what we are going to do in the on-going guide. As you move forward, you will come across a comprehensive guide that will help you to update your Xperia T2 Ultra D5303 to official Android 5.0.2 Lollipop 19.3.A.0.470 firmware. As soon as this update arrives for D5322, the same guide will help you to update your device. Let’s go through the guide now and get it done.

Early Preparations:

1. This is only for Sony Xperia T2 Ultra D5303/D5322

This ROM is only for the device mentioned above. Make sure that your model number matches the one listed above. To do so, go to Settings > About Device on your device and see your model number. Flashing this firmware on any other device will result in bricking it so make sure that you meet this requirement first of all.

2. Battery should be charged at least over 60%.

Make sure that your battery is charged enough to complete the flashing process. In case your battery is low and your device goes dead during the flashing process, you may end up soft bricking your device as it won’t complete the flashing process.

3. Backup everything!

Just to be on the safe side, you may consider backing up each and everything from your Android device. This is highly recommended so that in case anything goes wrong, you still have the access to all of your data and you can restore it immediately. You may backup everything as listed below.

• Backup SMS Messages
• Backup Call Logs
• Backup Contacts
• Backup Media – Copy your files manually to your PC or Laptop.
• Titanium Backup – If already rooted, use Titanium Backup to backup all of your apps, system data and other important content. If you haven’t rooted your device previously, skip this step.
• Backup Nandroid – If CWM  or TWRP installed previously, otherwise skip this step and perform this at the end of flashing.

4. Enable USB Debugging Mode on your device.

Enable USB debugging mode on your device. To do so, tap settings>developer options>USB debugging. If you can’t find developer options in settings, then tap settings > about device and tap “Build Number” for 7 times and you’ll get em’ activated under settings.

5. Install and setup Sony Flashtool.

You must have installed Sony Flashtool. Find the full guide here.
