Hi friend... Iīm from Brazil too and I have a g7102t. When you rooted the phone, the TV stay works?
I have some issues on my smartphone. The battery is very hot and terminate so fast. The GPS is very slow to connect.
I need to upgrade to 4.4.4 or 5.0 (CM12). But I canīt lose TV function.
Can you help me?
Everything works fine after rooting, including embedded TV. Unfortunately my phone broke some months ago, and I've changed to other model. So I think I can't help you with the other issues.
