How to re-format my mobile phone using my computer because I forgot my phone’s code that I installed
Firstly, in case of an android phone, you should try to change the code by entering your valid gmail id and password. The thing can save your data from wiping after the format. If the device is not a smartphone, then you have to contact its service center for the formatting as they have the software and rights to format a locked device. You need to bring your bill with you at the center and they will give you a formatted device, without violating its warranty.
