Hello,

Also for your fmms problem, you should call your provider support and ask for setting, i had to do so with mine.

Another thing you can try is to lower the image size, i also had to lower to medium size, this may cause your issue.

For your software install issue, it looks a lot like repository issues, you should have a look around and gather information on how and which to use. Or maybe yes, connectivity issue as suggested above.

Hope it helped.
