Replaced lightening connector and now 4G and phone service unavailable
I recently replaced my lightening connector in my iPhone 7 plus along with the loud speaker, the new parts work fine as it charges and the speaker is much louder however I can no longer get a signal or 4G at all.
There is a lot of mixed information online but does anyone know which parts may have been damaged and what I should be looking to replace?
Additionally I have tried all the troubleshooting for no service issues such as resetting the phone etc, none of which have worked.
Any answers appreciated, thanks.
Is this a good question?
