Unable to Activate - An update is required to activate your iPhone

I updated to iOS 13.4 recently and after the update i was not getting any cellular signal on my phone.

I tried factory resetting the phone since resetting network settings was not helping.

Now after my iPhone boots up it still cannot get a signal and i cannot activate my iPhone.


I have tried restoring my iPhone using iTunes on my Windows PC but it's still the same.

iPhone 8
