So I got my HTC Thunderbolt, rooted it, then unrooted it. What I'm planning on doing is rerooting it, then installing an MR2 based ROM, most likely Plaine Jane. Trying to remain mostly stock, with root. What I need to know is, can I perform a factory reset after rooting? Will that make me lose root? Also, would I be able to perform a factory reset after installing said ROM and MR2 update? In addition, what is this MR2.5 update? Is this just a leaked future OTA update? Thanks in advance!
