    I have a tmobile htc m9 with android 6 software number is 3.39.531.41.  The ota upgrade for nougat isn't showing up when checking for update. I also downloaded the software update for nougat from htc (http://www.htc.com/us/support/htc-one-m9-t-mobile/news/), but i get a error 132 signature error. Phone OS is not modified.
