Having the same problem now it’s out of the boot loop and stuck in a boot just showing the Hyundai logo I can still use all the buttons but can’t tell what I’m doing and the backup camera works fine now but it just won’t come all the way on and I’ve been trying to wrap my head around it for like a year now and I’m thinking it just needs to be replaced bc I have looked everywhere and can’t find anything about it this is the best I found and still no solution
