ICYMI: HTC One M9 Getting Marshmallow on T-Mobile’s Network Starting Tuesday

In case you missed it, T-Mobile has announced in a tweet that they’ve received technical approval to begin to roll out Android Marshmallow 6.0 to HTC One M9 models locked on their network starting this Tuesday. This comes just under a week after Sprint began to do the same thing for their HTC One M9 units on their network.


We suggest having a least 80% battery before downloading the software upgrade, as these tend to be pretty heavy downloads and take a little while to install while using lots of energy. But while HTC hasn’t said any of this themselves or even officially announced how big the update package is, it’s safe to say it’s probably pretty big.
