Reverse polarity damage I need help. I was using a generic usb charger to charge my android phone and it was charging fine but somehow the polarity was reversed. After being plugged in for some time, the phone became very hot and can't power on now. How badly is it damaged and how can it be fixed?
If really damaged - only by re-soldering broken components by new components.

But HOW? USB polarity is declared in standard, cable is impossible to insert at wrong position without break of connector.
