Can't flash Samsung S8 RMM: Prenormal

@Peeteey, you can see accurate “identifiers” at the top of the Android recovery screen. To see if you device might be the “Galaxy S8 Vodafone” you could check there to see if you see dreamlte, a variation of dreamlte and / or some secondary device codename. It is not uncommon to see more than one identifier at that location.

It should also be possible to make enquiries at how to identify a Galaxy S8 Vodafone model and whether there is any documented release procedure or if such is needed.
