My Phone won't switch on, it seems to be stucked

[Denham]

I've got an Sony Xperia M and today which is the 8th of December 2014, I installed a Theme for my phone using Sony Select. After the download of the theme was complete, I set it up and I wanted to restart my phone cause there was a Minor Freeze. After I switched it off and powered it back on, It Firstly said Sony, then the Xperia Logo and then the Coloured lines which go across the screen appeared. I thought that it might come on, but unfortunately it didn't. Please Help me fix this. Thank You.

You may need to perform a software repair using PC companion.The process will erase all internal memory.You might need to charge your device for about 1-2 hours before so the device has at least 60% 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).

Open PC companion->support zone->phone/tablet software update->repair my phone/tablet blue highlighted.Follow the steps given,do not connect your phone until prompted to press volume down while plugging USB cable. If PC companion does not start the repair process, you might need to run it in compatibility mode with Windows 7 (in some cases XP).
