Hi guys, I had the similar issue, as described here (Octavia 2021). I was able to solve it by myself. How it all started? I got notification on Monday that there is OTA 03A8 update that stated I should install it or some things might stop working in the future. I downloaded it in the evening while driving, and after I parked my car and clicked Install I waited 30 minutes but there was not any information that install is progressing. I turned off ignition, left the car, locked Then Unlocked, Ignition on, and Infotainment prompted me to login with my primary user account After providing username and password, hell broke loose with my infotainment Symptoms after update: After loading primary user profile, Infotainment gets stuck, and cockpit starts shining as Christmas tree Screen goes blank, but still on in the background eSIM icon was offline Force shut down, by extended holding of Power button doesn't help Unplugging and plugging infotainment fuse doesn't help Spent 1h trying to troubleshoot, but no luck After 24 hours, eSIM icon changed from Offline to Online (Tuesday evening) Workaround: I've discovered that if you force restart the infotainment (extended holding of Power button) and quickly enter the Guest profile, Infotainment starts working properly If you try to switch profile to primary owner, same issue above starts happening (so don't do it) Deleted Primary profile (only guest remained) Solution (in my case): I suspect that my profile got corrupted on Skoda servers, so when it starts download to Infotainment, corruption starts I used another email to create Skoda account, and signed into My Skoda app I used new email to login to Skoda infotainment, and VOILA - no issues. Infotainment worked perfectly since But I have Remote Access paid until end of August 2026, so I didn't had access to my car via new My Skoda app with new email Thankfully, when you choose and follow thru option to become primary user (via Infotainment + two keys need to be present in the car), exiting Remote Access subscription was transferred to new email. Since, Tuesday evening, everything is working perfectly. Hope it helps. Attached image shows info after fix.
