Random reboot - Sony Xperia M2

[Setob]

My Xperia M2 is almost a year old. For the last month or so, I have been experiencing a random reboot issue. I have made a sim swop to no effect. I have upgrade to the latest firmware. I have factory reset my phone, also to no effect. Returning to the store is not an option as I don't have a spare phone and I'm told it will take 6 weeks to get the phone back. Any suggestions would be appreciated. As my warranty seems pretty worthless, I am contemplating rooting the phone to see if it might make a difference.

I'm sorry to hear that.
I suggest that you raise this with your local support team to proceed with this in the best possible way.

Hi @Setob

I suggest trying to perform a system repair using PC Companion. This will factory reset your phone and erase all data. You might need to charge your device for about 1-2 hours before so the device has at least 80% battery. Make sure the device is not connected to computer or laptop and turned off (sometimes you have to press power button and volume up until the device vibrates 3 times or on some devices you have to press the small button near the SIM tray or on the back of the device). Start PC
Companion and select Support zone then Update my phone/tablet then in Blue Repair my phone/tablet and follow the on screen
instructions - When prompted connect your phone still switched off holding volume down or back button - This should start the
repair or reformat process.

If you are using Windows 8/8.1 or a 64bit operating system then adjust the settings for PC Companion and run in compatibility mode and chose Windows 7 or XP.
