So, my *rooted* LG G Stylo (MS631) on Marshmallow has a new "update" from MetroPCS. I searched on Google for an update, and T-Mobile's website still says that the latest version is 20b (since I would believe the latest version would come to the T-Mobile variant, first). As you can see in the screenshot, it doesn't have any actual specifics in the description other than the fact that it weighs in at about 68mb. I tried to use FlashFire to flash the update, while keeping root access and TWRP. The notification to update still sticks around, despite pressing "Later." Anybody sure what this is?
