I have an s9+ that says registering device then, processing failed whenever I try to update it! The current android version is 8, Samsung experience version 9, model number SM-G965U. PLEASE HELP
I can understand wanting to update your device. How are you doing the update? Is it through the phone or are you plugged up to a computer using smart switch?
I can recommend trying to download the update while in safe mode. You can get your device in safe mode following these steps.
Let me know if you were able to download it while in safe mode!
