It's from service manual for Samsung smart tv. You can find some of them here on forum. Use search box.

TV remote arrived, I changed BOM, Type and software in extended menu
Unluckly the problem is still there... selecting any HDMI the TV prompt that an update is occuring and reboot (loop) :(
Using a USB on the same one connect mini box, it works

Download service manual for your tv and check there for more info. Maybe some parts aren't compatible or need some adjustment. For now I'm out of ideas what you could try more.
I'm sorry

Check BOM and SW model in extanded service menu maybe you need to change that.
Thank you for your answer!

Entering the service menù, I'm not able to find SW Model and BOM Model, also I see "MODE: FAILURE" on top: the TV is not attached to antenna or satellite (see the attached image) :?
Change "Type" according to service mnaual it should be 48A1UU7WJ or check panel "type" on label on LCD panel and you have there 55A1UU8XJ
