I am running Liberty 2.0.1. Like many, I am very interested in trying the new official Gingerbread release from Verizon/Motorola. I understand and know it is not possible to upgrade on a rooted/ROMed phone. So, my question is... Is it possible to do a factory restore on a ROMed and rooted phone or do I really need to do an SBF? If an SBF is needed, can some one guide me to a viable and relevant link for doing so? I noticed a lot of SBF articles are not very current. Thanks for any help possible.
