A problem that seems to occur frequently. I found out how to fix the problem here on this forum. Unfortunately, you have to separate the top and bottom shell apart. If you go to the search section of the forum and type in IMU not working,it will pull up past threads about the issue. There will be many step by step instructions on how to do it.
If you cannot find information,post again and I can find it for you.
I need to get to work now. I’ll check back later.
