I recently tried to install the new marshmallow update which came up a while ago for T-Mobile, and during the reboot and installation, the screen turned into an error screen, and I ended up having to pull out the battery to restart the device because it was stuck on that screen. The phone is still in lollipop, and the version says 5.0.1, and when I check for update, it says I'm already at the latest version. Is there some way I can get the update again and reinstall? And what was possibly causing the error, and is there some way to fix it? Any help is appreciated! Thank you!
