mercedes w177 2019 ecm OTP cloning?

[+tomanycars]

I was asked if I can clone a w177 ecm afew weeks ago , i have asked many big name companies , KESS , FGTECH  to name a few 

 

i have done some minor research regarding the cloning of these ecu's , as it can be hit and miss , as it can't clone the OTP area , from how i understand it , the OTP is software locked not hardware. although i can't confirm. , has anyone had an success with complete clone with iprog?
