mine did that at weekend, i flashed emmc which was normal, then root which only took a second to do (root) at this point i thought oh dear. so without turning on or disconnecting i flashed root again which then went through all the processors erasing cmt, etc. then phone restarted as normal just took longer on the dots screen.

I flashed mine again just to make sure everything was ok, because the apps were a bit sluggish. I had to flash the root twice.

I wonder why mine does this? Anyway, it doesn't matter as long as the device works!

Glad you got it working mate.
