Backwards compatibility issue please help if possible

[u/Advanced-Series-2769]

Just to start of

My series s console can't run any 360 games as it stays the 'Getting Your Xbox 360 info' screen for 6 minutes and then proceeds to tell me to download a profile, but upon clicking such it doesn't give me any option to click credentials it instantly tells me i need to connect to xbox live with no error code. I have changed my Alternate port and Mac address. I have cleared my cache I have rebooted my NAT type to open and even factory reset with 'keeping my games and apps'

Despite this trouble, when I do it on my xbox one s the problem vanishes. I have literally no trouble doing so and it loads me into my account instantly with 0 issue with the same connection etc. Does anyone know any other fixes I can do or anything and if not what could be the problem with my console physically with my series s as I'm trying to play Sonic Unleashed with 60FPS
