I have to find a sweet spot for the charger plug on the phone's outlet (mini USB port) to be able to start charging. It seems that the plug is too loose and to make it charge, I have to apply some force so that the tip of the plug reaches a sweet spot inside and it works. If I release my hand, it doesn't charge. This is very weird. It started yesterday when I tried to charge the phone and a black screen with white characters saying "Bootloader" and some info about the phone. It did that for some time and later, the Motorola logo was showing up for some seconds but not charging. This is really very problematic. I can't normally charge my phone. Any idea of what can be happening?
