If you have one of these phones, you may have noticed the “unauthorized charger” error prevents you from charging your phone; in my daughter’s case, said charger was the OEM charger that came with the phone.
To work around this issue, put the phone in USB mass storage mode.
menu->settings & tools->tools->USB mass storage.
It should charge from any USB adapter at this point; this post is probably in violation of some hacking law.
