One thread is enough however

Try performing a system repair using PC Companion as this will often fix issues - This will factory reset your phone and erase all data so best to backup before you begin

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 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

im sorry cause the one thread that I've posted to the other topic. ahmm. I dont have a Pc in my house. Can I factory reset my phone by itself? do you think its a good idea? Cause I don't have very important details on my phone. My phone is still have a warranty cause i bought it Last 9/12/14. Last Monday I went to the malls then they said bring my phone to the service Centre and thats a little far from my house.

Normally I would say perform a system repair especially if you have upgraded however a factory reset is the only other option you appear to have unless you can use someones Pc
