Xperia Pro MK16i stuck in boot-loop (showing Xperia logo only)

[Ryoushi]

I owned an Xperia Pro bought on Feb 2012, and running ICS updated by PC Companion.

It keeps restarting/rebooting (symptom very similar to http://talk.sonymobile.com/thread/51181) after turning on bluetooth today, showing repeatedly only the Sony logo and the animated Xperia screen.

This phone has NOT been rooted, NOR unlocked the boot loader.  It is using the latest firmware available in my region as of today (4.1.B.0.587).

I tried starting the phone with/without the SIM card and/or SD card with/without USB cable but NONE of the combinations helps...

It was set to Mass Storage Mode, so it could NOT be connected to PC Companion for software update.

I am wondering if it is still possible to rescue the data inside (contacts, SMS, etc.), by for example, flashing newer firmware from uliwooly, or send to Sony for recovering.

Thanks in advance for any suggestion.

Here's the ADB log when booting until it restarts automatically and re-enters the boot-loop:

Try using 'Bluetooth file transfer' from the market, and see if it solves your problem

The phone just rebooting continuously and never even gets to the home screen.

I suggest that you try to run a software reinstall using SUS.

If the problem still remains you should contact your local support team, to have the phone examined and fixed at an repair center.
