Do not get your hopes up. I found this forum after my update. In my case my problems started after i udated to NRD90.T813XXS2BRI1 on my tab s2. After the update my battery life is terrible. Before it drained 2% leaving it overnight. Now it is about 15-18%. So i also stared looking for solutions and found this forum. Not really hopefull though.... I already managed to find the software for the prevoius build. But there does not seem to be a solid way to revert back to an older version is there? I mean i also read a lot about bricked tabs after an attempt to revert back to and older build. Could a custom firmware be a solution?
