No service after cleaning
OK i have some iPhone 6 with all have the same issue they came in with no sim issues which i resolved by cleaning the sim port but a new issue has arose.
The phones either keep saying searching or no service but if i clean the connector the antenna connects to the little push on in between the battery & dock connectors on the board i get a signal with 4G.
I try different sims in them & they work great until i reset them back to factory settings they then go back to searching or no service.
Would it be worth warming the connecter up on the board essentially reflowing it?
Anyone else have this issue & did you resolve it if you did how please?
Any help or suggestions would be amazing.
Thanks guys in advance
