Hi, is it possible to delete the entire software (os) on my phone (virus infected) and install back a new software; as in reprogram with a new os? Factory reset doesn't help. I think i have some major viruses in my phone, these porn apps keep popping up with new ads, opening automatically, sometimes turning on my wifi & data automatically, sometimes restarting my phone and stuff.. the phone is literally freaking out, can't use it at all. I factory re-setted it quite a few times, doesn't help. Anyone know what to do here?
