"Hi, My Name.
Thank you for using our product.
Your model V2 was 3 years ago manufacture product.
The Android version was 4.0.
Now we use the 7.0 version of Android.
Kodi 17.6 services only work with Android version 5.1 and above.
Android box is like a smartphone.
Technology is changing too quickly.
Previous chipset does not allow upgrades.
This is not the issue of boxes, it's the chipset problem.
Existing boxes can only use different functions than using a server to watch live TV.
I'm sorry I couldn't help you."

Hope that Helps Others to Understand...!
