I've forgotten the unlock pattern for my Qmobile i7i and it does not provide me with the option to enter my email, backup pin, etc. Factory restore is not an option as there is important data on the device.
How can I bypass the pattern lock?
Well, first you can do is to make the backup of all the files which you can do so by copying all the files from the phone to your PC via USB connection.
The files you copied will include the contacts, media, system related file. Once you have copied all files then you can later copied back to your phone after phone reset.
Here is the link to reset your phone:
