Xperia T Re-booting after upgrade

[JohnnyW]

I want to re-open this thread, since this topic is from my point of view far from being solved!

The problem is, that my XPERIA T keeps rebooting every now and then - multiple times per day, even multiple times per hour - sind I upgraded to 4.3 (9.2.A.1.205). Before the update, everything was find. No third party program was changed in that time period, so it can be ONLY due to the update.

First of all, sorry for the late reply. Does this problem still persist?

If it does, I suggest that you try to repair the phone software using PC Companion..

Before repairing your device you may want to backup your information first. Check out this topic for more information on how to.
How to backup?

If the issue should still remain I think that this needs to be examined and fixed at a repair center. For more information about how to submit your phone for repair and where, contact your local support team.

Hi! I had the same problem, i think... Besides, the phone did nor recognise the network, usually showed " Emergency calls only".

That problem was solved(rebooting and not recognising network card), by exchanging for a new sim card! The one i had before was 3g ready, not 4g, and vodafone p recently updated their services with 4g... whwn i made the update on the phone with android 3.4, phone got confused all the time and that happened! Now, with 4g new sim card everything is ok!

Hope i´ve helped
