Restore signal bars from numeric DB value

[kecinzer]

I have problem with restore default signal indicator in my iPhone 7 Plus.
When I was on iPhone 7 I was able to enter Field Test Mode and switch to numeric DB signal. Then I switch to iPhone 7 Plus with Intel modem and I have numeric signal because of my backup. But on iPhone 7 Plus I can't enter Field test mode and can't restore signal indicator back to default.

Can you please give me some advice how to do it? If it's possible?

Thanks .

hard reset of the phone and try it again? i just tested on my iP6 and was able to put it in DB and then back to stock dots.

I don't want to lose all of my data. If you mean reset phone to stock. I already contacted Apple Support and engineers working on it .

@yanki01 is just saying to hold the power button and volume down button at the same time until the Apple logo appears. You won't lose any data or back-up's.
