Q: anew I phone 6 while go through setup seteps it restart by gives red screen

Hey almohdk,

Congratulations on the purchase of your new iPhone. I am sure it is upsetting to be having difficulty getting it set up for the first time.

If you are having an issue with your iPhone restarting unexpectedly during the setup, I would suggest that you troubleshoot using the steps in this article - 

If your iOS device restarts, displays the Apple logo, or powers off while you're using it - Apple Support

In particular, since you appear to already have the latest version of iOS installed -

 

If you still see this issue after updating, contact Apple Support.

Thanks for using Apple Support Communities.

Be well,

Brett L
