[Certified][A10] SW update - 10.0.2 for Teracube One

We have a new bug fix update for T1. This build fixes the following over 10.0.1

  1. WiFi Calling (WFC) feature for supported carriers
  2. AT&T Certification and compliance
  3. Fixes for various carriers, enables IMS for most supported carriers

** Existing Android 10 users, please note: **
Due to a few technical limitations, users already on Android 10 may need to factory reset in order to use WFC and other telephony fixes in this update. If you wish to not reset your device, you may want to wait for the next build (10.1.0) which is currently being tested for certification with August Security Patches.

Prerequisites: Make sure your phone is sufficiently charged.
