I currently have a VZW D3 running MavROM 4 w/ Safestrap. How easy would it be to restore it to stock VZW? I've SBF'd before so I'm use to it but all the fastboot links I can find are dead. I think the factory rom is still in my non-safe but not sure. Could I just boot into non-safe, remove root and safestrap and be done?
