Those screenshots confirm that Redmi K50 Ultra does not have an EID, and thus no eSIM capability. If we make a China ROM-based shared ROM for both Global and China models, we'll have to separate the eSIM feature to be exposed on the Global model only.
Value "diting" for ro.boot.hardware.sku on Redmi K50 Ultra is expected and known, what interests us is the value for Xiaomi 12T Pro (it can be either "diting" or "ditingp"), so we're only waiting for
@gogocar62 or any other Xiaomi 12T Pro user to check "getprop ro.boot.hardware.sku" on their device, then we'll know how we should continue.
