I've been trying to update my LG G3 to 47A for a few weeks now. I can download the update and go to install it. When it gets to 3% every time I am met with error 0x1125000 and then it restarts saying the update failed. Once its's rebooted I go to the system updates panel and see Error code: 402. I have tried to factory reset several times as well as cache wipes. What do I do?
