I received and installed a firmware update two days ago. I noticed cell signal icon was replaced by a crossed circle; 🚫. Also, the options for 4G and 5G are nonresponsive, the menu options are not greyed out but they are unresponsive when pressed. So I can't connect to my cell service provider. Tried lurking around the web for a day with no success.
What I've tried:
-Restart
-Flight mode on/off
-Reinstall sim card in both slot 1 & 2 - !There's not even any prompt for entering SIM-card! The phone doesn't even seem to be looking for a SIM-card.
-Confirmed SIM to be working on another phone
-Factory reset
Hardware: SM-G9810, Snapdragon Korea version 5G
Firmware: One UI 3.1, security patch September 1, G9810ZHS3DUI1 / G9810OZS3DUI1 / G9810ZCS3DUI1
Right now I'm torn between trying to downgrade or await the next update hoping it magically solves the problem.
I would be glad to know if you've heard about any similar cases and welcome any creative attempt of solving the issue!
