Same issue even i faced i tried almost all possible ways to fix it but no use and i spent around 4hrs time with apple agent as well finally she told me to visit apple authorised service center and they are now saying its hardware issue how could it will be an hardware issue post updating ios 14.6 this issue arises and now apple care executive told me to restore it over itunes and now its not able to activate and its keep looking Mobile signal.
Which is hurting a lot apple has to do an replacement programme for this issues if not we are going to waste around 300$ absolutely waste.
