I downloaded the firmware (.img) of my Android device (Boyue T62D) just to have a backup of it. I'm in the Indian countryside with an extremely limited internet connection, so this is a huge file for me. The reasons I'm unsure are:
I can't extract the file (just to look at the contents) in any way on my computer (OS X 10.10.1). Is this to be expected with an Android image? I tried to unpack it using a variety of methods (like converting it to iso first). (none too fancy though).
I was out of the house when the file was downloading, and when I came back it looked like the file was done, but the Internet connection was broken. But the file seems to have the same size as it is supposed to have. So what got me wondering was the fact that I can't unpack it. If you guys could just tell me that this is standard, and that .img files are very hard/impossible to extract on OS X, that would be great.
