Still can't seem to get the phone to be detected by Windows or Ubuntu, can't see the phone listed on ADB connected devices.
I've tried several different USB leads including 2 genuine ones that I bought off of eBay which are identical, but still haven't had any luck .
I don't think the port has become damaged as I cleaned it carefully, the phone charges fine, but it still isn't displayed properly on Device Manager.
Also be sure that the USB cable is working perfectly fine. Yet, if all is correct and not even Ubuntu can recognize your phone, it is quite a bad sign....
