All providers. Specifics please!

Hi folks,

I used to use Smart IPTV then my provider moved me to stbemu app which worked fantastically well. This recently went down and I am now without a supplier.
I’ve asked 2 providers on here for free trials and have been sent details in emails.
Neither provider seems able or wishes to provide a guide as to exactly what the step by step process is in regards to what to download.
I have 2 firesticks with both the smart IPTV and stbemu pro apps installed, neither of which currently work obviously.
I just need someone to give me some specific and succinct advice as to what I need to do to get up and running again rather than being sent these generic free trial emails which make no sense!!
