Hi guys, I just started to set up my new octagon sx988 4k from here and in the set up phase I stupidly chose tv resolution 2600 but my tv is only 1080p and now I can't complete setup or view tv setup and I can't go back to start to change the resolution as its just saying tv resolution not compable I should just kept it at 1080p
Do I have to reflash the box and if so where is the guide , I've looked on the guides on here don't see flashing guide. Any help appreciated 🙏
