I'm using Karbonn Titanium Octane Plus. A few days ago I had a battery problem and my phone died. Afterwards, I charged the battery by taking it out and charging it in a multi-charger. After it was full, I put it back in the phone again.

The phone showed a Privacy Protection Password screen. I tried the default '1122' but it said 'wrong pin'. I took it to a local mobile dealer where he hard reset my phone but the password screen is still there after reboot.

Is there any way to find the password or repair it without flashing the phone?
