Why is my Nokia 635 switching to airplane mode while trying to install Windows Phone 10?

[Windows Central Question]

While trying to install Windows phone 10 my phone turns on airplane mode right before it reboots to get ready to install Windows Phone 10.

I think its normal.. Whenever the phone restarts it first goes to airplane mode

It does if right here but when it gets to the count down 1. Then when I check for updates none are there. I think it isn't doing anything because it turns on airplane mode.
