I'm running Nougat but I've not been happy with the battery life. I'd like to odin back down to the last MM update. I shouldn't have a problem because it uses version 4 of the BL. When I check TMO's support site for the S7 they call the Nougat update "manditory". So my question is has anyone been able to stay on MM unrooted and not been forced to take the update?
