i Guys, I'm new here.
I have Samsung Galaxy Tab 4 8.0 3G (SMT331).
My os version now 4.4.2 kitkat.
I live in Indonesia (XSE).
I want to install my firmware from other country who have Lollipop version (Rusia, 5.5.1) that have same model SM T331 too.
Is it possible to change the firmware?
Any risks? Like no network connections?
I dont know my Tablet already unlocked or not, but I can change all sim card gsm model in my tablet, is it called unlocked?
Thanks for advance.
