Just in case if the device is not rooted, with the help of below mentioned instructions you will have to root the device.

With the help of below mentioned steps, create a backup of all your precious data as in the due course of this procedure, the data will have to be wiped off. Don’t backup the data with the help of PC Companion as it won’t recognize the device in the custom ROM firmware.

SMS – Use “SMS Backup & Restore app”,
Contacts – Sync with the Gmail application,
Call Log – Call Log and Restore
Images, Songs, Videos, Files – Copy to internal / External SD Card,
APN and MMS Settings – Note down from the path “Applications > Settings > Wireless and Network > Mobile Networks > Access Point Names

Enable the USB Debugging in your SONY Xperia T from the path “Settings > Applications > Development > USB debugging”. The USB Debugging option should be ticked. Also, minimum charge left in your Xperia T should not be less than 40% as it may get turned off in the middle of firmware update.

If you are trying to apply this from the custom ROM firmware then, select “Wipe data/factory reset” & “Wipe Cache partition” so that this will clear the cache which is there in your device.
