Hi to everyone. I just got my brand new Xiaomi Mi2, but I have a big problem. I try to upgrade it to Multilang ROM from this site, but it doesn't let me copy the file in the path called "Internal Storage" in Windows Explorer. It stops somewhere in thw middle of copying the file and says "Cannot copy the file, this device has stopped working or has been disconnected". My Mi2 is still connected to my laptop and it's charging. And it still shows up normally in explorer but I cannot copy the file. What am I doing wrong?
