aymanelk06 , via OnePlus 7 , Sep 3, 2020 : I'm currently running version OP7_02_BETA_17 and I want to go back to stable on my phone. I factory reset my phone, and then I downloaded the latest version of Oxygen OS from the oneplus website. I then when I went to local upgrade to try to install it, I got an error message saying that the version of your selected package is lower than that of the current system. To avoid failure when booting up, downgrading is not allowed. What can I do to get back to stable?
