hi mate
it's a hardware pairing
providers is conax 0b00:00000 (mytv africa)
box is SRT4675A with processor cpu STI5211
African satellite tv mostly uses irdeto encryption which within itself is also a nightmare regarding cs due to surflock and pairing/security..i have not heard of your provider or stb but conax cards share really well and are doable.
Your rsa key that you need will more than likely be stored on a bga chip within the motherboard of your reciever although i,m uncertain about that.
Your best bet is to take several close up pictures of the motherboard and post them on here and similar forums to seek advice.
It gets really technical however... the chip has to be located/confirmed for rsa location and then removed,, specific programmers like up2008 are required too to dump the chip and then other works to decipher the dump to extract the key is required which is not supported here as discussion(so be careful what you ask for)... bga chips are the most difficult i have came across to re-solder back onto boards unless you possess an rework infrared bga station with correct stencils for bga chip sizes... but it is very easy to remove the chips..if this is the case of bga it wont really matter as you will only require the rsa from the chip anyway.
So in other words the chip would only have to be returned to the motherboard if
A : you had engineers visiting your home
B : you required some sort of ppv event you could not purchase
C : You wanted to cancel and return the stb.
Also best to send oscam logs and configs...they do help sometimes
