I am having trouble and think I know the problem but just want to cover everything.
I have done a mj5 restore then a factory reset to make sure it was clean.
Still could not get a solid lock standing in my backyard.
Went to Best Buy and let them flash it. BIG mistake they had nc2, not what I wanted to do.
If it worked right I could live with it, but it doesn't.
The big question to you guys is if you use these apps do they show satellites?
