My S9+ software update did not complete and every 15 minutes this pops up "firmware update could not be completed. Error: Internal error (407). This is very annoying pop up. Please help!
did a bit of research on your issue and found this thread. it has many confirmed fixes for many similar models to yours. I would give it a full read and try the one best suited to your model. I seen a s9+ fix and a note 9 fix both of which may work for you. Good luck!
Go to 'Settings' > 'Software update' and hit 'UICC Unlock' It loads for a moment, then says SIM Restricted... Hit 'OK' It takes you back to the 'Settings' > 'Software update screen'. Hit 'Download and install' It loads for a moment, then says Your software is up to date... Then open that notification saying the profile didn't update. It loads for a minute, then says Profile updated... Hit 'OK' It loads again for another minute and says something similarly. Hit 'OK'
