The only thing you can do is to perform a system repair and see if that fixes the issue

Switch off your phone and unplug from Pc (Hold volume up and power for around 10 seconds)

Start PC Companion and select Support zone then Update my phone/tablet then in Blue Repair my phone/tablet and follow the onscreen instructions - When prompted connect your phone still switched off holding volume down - 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

Its not working. Tried several times. A red light blinking near front camera.

Then you either haven't got the drivers installed or as said are running the above operating systems or you aren't doing it correctly

I am using windows 7 64 bit. I found a message that the driver software not installed properly. Now the mobile is not opening. I will try again in a 32 bit machine. And after that I will inform you the update.

Thank you so much
