Got an AT&T HTC Vivid here, and a NET10 SIM card. I noticed there was a SIM Unlock option in the boot loader, but it just gives an SDcard error and asks if I want to reboot. I've already tried factory resetting the phone, and booting it fresh with the new SIM in, but I'm not sure what else is required or how to proceed.
That SDcard error, might it want to access an unlock code in a file I'm supposed to be putting on there or something? Or maybe create some .ini file to tell it at boot to connect to a different network?
