1.) All water damage phones must be cleaned with isopropanol and get a new battery before anything else. Ideally, desolder the EMI shields, clean with ultrasonic cleaner, spot clean with brush. Assuming you've done the best you can on this, then if still a problem...

Hi Emil,
Thanks for your email.
Your troubleshooting looks like this:
1.) All water damage phones must be cleaned with isopropanol and get a new battery before anything else. Ideally, desolder the EMI shields, clean with ultrasonic cleaner, spot clean with brush. Assuming you've done the best you can on this, then if still a problem...
2.) Connect to WiFi and make sure time/date is current. Toggle airplane mode off/on--this will solve a software problem when phone is searching after battery connect/disconnect due to wrong time/date. If not solved
3.) Check in settings--general to see if phone is showing you its IMEI---if not, then you have a baseband problem....this is a board-level repair that requires desoldering of the SIM tray itself, and then a lot of time testing individual components for loss of continuity/shorts that are part of baseband circuit.

good luck, and post here with your update
