Hello. I bought my ZC520TL around 4 years ago now, and I stayed in Marshmallow throughout my use. I want to update now to Nougat but system update doesn't do anything. If I try to manual update to any update applicable to my SKU, a no command error appears. I factory resetted my phone and it still persists. I saw a post saying that one can do this by downgrading to 13.1.0.51 but I cannot find that firmware on the ASUS website. None of the solutions in the internet has fixed my problem. Is there any solution to this that I don't know of? Even if the phone is not supported there should still be at least a way to get past this. Thanks
