See you donít have any other options except this. so you will have to decide what you need to do. for me I think the best option would be to do a factory reset. Before starting with that procedure I would like to say that keep a backup of all the data. because this procedure will involve deleting all the data in your phone. so thatís why always keep a backup and then only proceed ahead.
1) in the home screen go to the menu.
2) In the settings tap on privacy.
3) Tap on factory data reset option, then select reset option.
4) Enter the password of your phone and then tap on yes to confirm the option.
So thatís how it is done do give it a try and let me know what is the outcome. I am waiting to hear it from you. Hope thatís fine.
