So I recently bought an SPH D710 over ebay and when I first received it the micro usb needed to be plugged at a certain angle to work. I have yet to flash it because my current Verizon cycle has not ended yet. The problem is that the micro usb port condition has deteriorated, and requires extreme effort to be recognized as connected. If I go to a metro PCS flasher, will it be required for them to use the micro usb port, or will they be able to flash it simply by them adding my ESN and changing my PRL?
