How to downgrade your Xperia T2 Ultra Lolipop to Android Kitkat

I was facing very bad experience in using my Sony Xperia T2 ultra phone after i upgraded it to Lolipop version.

The phone was pathetically working slow. I wanted to go back to factory version of this.

If you wish to do the same, here are the below steps and then a you tube video from external source to show how these steps can be followed.

1. Download Flashtool from

2. Download Kitkat 4.4.3 from
https://drive.google.com/file/d/0B1oU02TyhZkAVTBvUU9MamRQZzg/edit

3. Copy above downloaded kitkat 4.4.3 file to C:\users\<username>\.flashtools\firmwares

4. Start Flash Tool.

5. Wait for any pending things to be completed in flash tool.

6. Click on left most button (which looks like zigzag spike). This will start the flash mode.

7. Now select the file which would be the one we just copied to flashtool directory.

8. Start the flashing. Wait for some time. Follow the onscreen instructions. When asked to press the back button, press the volume down key.

9. Wait for flashing to complete.

10. Disconnect and restart the phone.

Below is the youtube video to explain the above process
