step by step method is straight that put latest oscam in your receiver' put credentials and that's it.
i am currently using only enigma2 based receivers. if you cant be able to locate exact oscam cardserver for spark os then put enigma2 os as secondary option in your 2020HD. then put latest mipsel oscam and enjoy watching media just for educational purposes
i also have a 2020HD box with me but it is still in packed position since 8-10 months.
