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?

nihalali , via OnePlus 7 Mirror Gray , Sep 3, 2020 : Hi there, https://forums.oneplus.com/threads/...-for-the-oneplus-7-and-oneplus-7-pro.1099154/ Go to the above link. This is the Open Beta 1 thread. Download the rollback package to Android 9 and install. After installing, u will be on Android 9. Then download and install 10.0.1 or 10.0.2 or 10.0.3 (any 10.0 version). After that download and install 10.3.4.
th0mash , Dec 1, 2020 : I would like to change from Hydrogen OS to Oxygen OS, but I downloaded the last version for my phone, put it in root, but when I tried to install it, it says "The version of your selected packages is lower than that of the current system. To avoid booting up failure, downgrading is not allowed." Therefore, I guess that I want to do the same operation as aymanelk. Is it safe to use the rollback of nihalali on my version of Hydrogen (10.0.10GM21) ? Or should I use an other rollback version ? The file used is : OnePlus7ProOxygen_21.P.31_OTA_031_all_2011052258_42a665d7dc95490e My Smartphone has : Hydrogen OS 10.0.10GM21
