I bought a G4 LS991 Gizmo Arena. But I'm facing so called bootloop problem. I had 7 days replacement warranty but at the 8th day it went on bootloop. Everyone is saying to change mainboard . But LG is replacing all bootlooped phone. But I don't know where to or how to reach LG in Dhaka to submit my phone so that they could replace it for me. I have also talked to Gizmo Arena but they are nothing but money thieves. They won't do anything about it. Please help me out guys.
