Did you also try a factory reset?
For downgrading please use the msm download tool https://www.getdroidtips.com/unbrick-oneplus-nord/
And then install the 22.214.171.124 zip
what are you trying to flash?
Where did you download it from?
From OnePlus Nord official website.
But why do you want to install this? This version is older than your installed version. That’s why you are not able to flash it via System local upgrade method.
Actually I have found some bug like when I connect bluetooth device with phone. I can see it in my bluetooth settings but can't find it while changing between devices in volume settings.
And you want to downgrade to an older version?
A downgrade will wipe your data
I have already backed-up my data. Please share steps to downgrade.
But it should work😊.
Nope! I haven't tried resetting it.
You can give it a try
But hard reset for what? To downgrade or for this bug?
For the bug.
If you are still facing the issue after the reset, you can downgrade
Sure! Thanks. Will check.
Any recommendations for custom ROM?
On OnePlus devices the Downgrade or Upgrade proccess is very easy to understand : for OnePlus the policy (and not general Android policy) is only based on the date of the build and nothing else. So of course you cannot simply downgrade from OS 126.96.36.199 to OS 188.8.131.52.
To downgrade properly you must simply use a SPECIAL downgrade package such as this provided in Open Beta thread number 1 for OnePlus Nord which is a downgrade to OS 10.x.x.
When the downgrade is done any Official OnePlus release with a superior build is easy to achieve.
As usual the downgrade delete the datas, apps and parameters so a backup is recommended first on an external device (HDD, SSD, computer ...). Warning : it's only USB 2.0 transfer protocol !
Note : OxygenOS 184.108.40.206 is considered a very bad build and radical improvements have been made since OxygenOS 220.127.116.11 with major bugs now solved (notifications, battery drain and much more ...) and consolidated in OS 18.104.22.168. It's the reason why the version semantics has accordingly changed.
