Settings ->  backup & reset ->factory data reset, asking for password which was never set. Please anybody would help?

I tried last four didgits of my mobile number, which did't work.

[vsbrt]

just use the password that u are using for screen lock

If the above does not work, the default code for all of our handsets has always been 0000.

Thanks Vsbrt and Sam.

Vsbrt: -I never set any passowrd for screen lock or any other fuctionality for this device.

Sam - 0000 is also not working.

It's new handset, just bought couple of days back.

After updation of software through update center, causes issue and device is affected by lock screen bypassed bug and it's showing emergency call screen.

I'm trying to reset device with factory settings , but it's asking for password.

Please advice.

Thanks.
