W205 Hitch (Code550) Programming

[novembro]

I recently got into coding vehicles (gathering info for now). In the next few days I'd like to unlock SA code 550 for my W205 T Model (2015). So now the questions:

1. What program would you use to get this done? Xentry / DTS / Vediamo?
2. What hardware would I need? (purchased an open port recently)
3. What would the process be like for dummies?
4. Is there anything I forgot?

Thank you in advance! I like how many people are here with great knowledge!

A detailed description of all four points will take several pages in A4 format.
