Samsung Update - no service

[Tanktheram]

Note 20 Ultra. Just did the Samsung pushed update. Immediately left with no data / cellular service.

Airplane mode button is half illuminated.  Used the Samsung Members app, did a test for networks - shows "no errors". Have reset network settings. Have tried someone elses SIM.  Nothing. 

Anyone else experiencing this?

I have the same problem… any update?

I wonder if using safe mode would let you change the network. And then whether it would stay set.

-IMEI is not blacklisted

-Phone will not let me change network signal/configuration. Its stuck on 5G. 

-Searched the internet, no similar issues which I've found. Off to the phone repair store again I guess? 

[Tanktheram]

Thank you all for the suggestions and feedback. 

-It is a phone I've had for a year. I bought it off of a phone reselling retail store. 

-My sim works perfectly in my old "backup phone" Galaxy S8. 

-I Will check the network settings and try the 4G setting. I do only subscribe to 4G public mobile. 

-I've ignored the update for days, but it was getting annoying so I did it today with time to kill.

-I chatted online with a Samsung rep. He asked me to send it in for service. I said it was Samsungs update? Why should I send it away? 

-I will check the IMEI and respond. Thank you. 

Bad that my backup S8 is becoming as regularly used as my Note20 Ultra.

@Tanktheram 

this seems to be a common issue with oneui 5.1. if, your device has 5g ability, change the preferred network to LTE/4g and see if that helps. the update seems to have broken the 5g antenna. if, you are still experiencing issues, it's possible you will need to learn how to use ODIN software and revert back to a previous software version

hi @Tanktheram 

maybe check if your phone is blacklisted

Is this a new Samsung Note 20 you just purchased or is it an old device you had for awhile?

Maybe Samsung's update bricked your phone?
Search Internet for similar issues. Maybe there is a solution. Can you reverse update?

I never rush for any update on phone or my computers. Always some bugs, untested features and similar crap.

Seems a chat with Samsung is on tap. Does your sim work in another phone?
