seriously? 500 just for downloading and flashing the firmware again. you can do it yourself by following this guide: [HOWTO] Flash original firmware on P690. for anything else PM me. i can help as i have flashed firmware 2-3 times in my Optimus One and procedure is same.
I'll second that.. You don't need to pay for something that we could help you out with.. And flashing firmware and rooting etc. is not that difficult as some people believe it.. Even on your own you can do a lot of troubleshooting with your phone software.. All you have to do is spend time for reading..
Easy step by step procedure is available in xda, home button fix it from him.
Go to settings, then security under screen lock check whether it is selected as none
Guys thanks to everyone for the suggestions out here. Strangely each day I seem to get piled up with new problem. I will list the issues again.
1. Phone is doing an auto dial after I get an incoming or outgoing call.
2. Home button is not working.
3. Phone is not getting auto lock
4. Battery is draining out much faster than before.
5. Date & Time settings are changing since I tried to remove battery and put it back. This was one of the suggestion in one of the sites I googled.
Last two problems started from yesterday.
I apologize for being noob but no Idea what does flashing and rooting mean. I mean haven't tried them before.
I'm Ok taking a back up of data from apps and doing a factory reset.
Not sure how to do back up of Contacts on my phone. Have a software using which I did a back up of SMS earlier.
Waiting from you all to get the next step.
