Xperia T / LT30p keeps crashing after battery replacement

[kArEkA]

Hey everyone,
I was using my Xperia T for a long period playing some games, then the phone became SO HOT near the back-camera and crashed.
It doesn't turning on for a few minutes and after this, the smartphone wasn't the same.

On first weeks my phone became full time on when connect to the power, but on battery it crash.
I did the soft and hard reset and firmware update. Nothing worked, so I decided to do a battery replacement (DIY mode).

Now, with the new battery, I tried to stress the phone again AND the problem persists. When I try to use any light or heavy app, it crash.
This occurs with/without SIM, SDCard, on power or on battery.

Any idea? Solution? Ty in advance!

How about if you use the phone in safe mode?

Hi, suggest performing a software repair. Hopefully it is just a software issue.

Try either PC Companion and Update Service,

Be aware that this process will erase phone data completely, backup if necessary.

Good luck and fingers crossed.

Same problem with safe mode and soft repair with PC Companion =(

In the beginning I noticed when I activate the "Tethering & portable hotspot" I got the following message: "Tethering error - Error occorred during tethering"

This could be a hardware related problem? Maybe the mainboard? I hope not!

You should visit a sony service:

I agree, but none of the Sony services in Brazil can solve this (my Xperia T comes from United Kingdom and they can't import any part).

That´s why I'm trying do it myself 😃

I'm suffering exactly the same 😞
