Hello; I do have a BuzzTv XRS 4500 with the last update dating to february 2024 and i do have the option of changing the MAC address on the bottom page of server settings with the blue squre button and i can even change the device ID 1 & 2 which are an extremely long number but still i tried to change only the MAC address for one subscription but it didn't work and i guess i had to change the 2 device ID to really see if it works but i'll have to copy and paste those 2 large numbers and with an android box i'm not too familiar on how to do this ...Hope this helps!
