I’m working on this phone and it appears that the only thing wrong with it is that it says “searching” or “no service” at the top. I have tried two working SIM cards and both do the same. At one point it had signal and worked, but as soon as I put the customers sim back in the phone it went back to saying “searching” What I’ve done: Reset network settings Reset all settings Checked for network update Put in recovery mode and restored Installed an antenna that I know works Any ideas on what else it could be?

What kind of repair have you done on the phone? Sounds like you might have messed up a component or two on the logic board. Take a good hard look around the antenna connector below the battery connector and see if anything looks scratched, damaged or missing.
