Yeah. I want to downgrade to a10 too. Is there a way to do it with or without losing data?

You need to, search for the roll back zip on the oneplus Community site. No way to save data,

Downgrade Android 9 to 8.1

Hello everyone,
It is possible to downgrade to Android 8.1 from Android 9 on Samsung A9 ?
I updated it to version 9 and it is very confusing to use as design changes are looking really bad.
If i restore original samsung 8.1 version what program do you recommend for full data backup so i don't loose any data/applications/pictures on my phone ?
Thanks.
Apps are linked to google account, they can be re-downloaded. As for data from the applications you'd afaik need elevated permissions to access that data or a custom recovery. Pictures you should be able to easily back them up to your PC. Generally you can always downgrade but you may be nagged about updating. Also if you had a custom recovery and restored data to an older version, it may or may not cause issues.
I can't give you full insight because the last device I've used relating to samsung was their note/note pro, and the s6. I just thought I'd toss what I do know here.

How can I update my phone to the latest oxygen os without losing root and most import

I am on a 10.3.0 oxygen , I have rooted my device, unlocked bootloader etc.
My phone is currently very unstable, I get FC and phone freezes often.
There is a new firmware update which is over 1 gb.
Is there any way I can install latest update / oxygen firmware, without losing data and without losing root?
I can't wipe / format the phone as I have few work related apps which simply can't be reinstalled.
Kindly assist.

Question [TB-J606L] Downgrade from Android 11

Hello. Yesterday i installed latest OTA Android version (TB-J606L_S320030_210923_ROW) and noticed that it is really slow and it has even more bloatware that i don't want. I don't need to root it (because of bloatware removal) as i also need to revert it to default state as it was before update.
1. It is possible to find which version i had before this upgrade?
2. How could i downgrade system to previous version (i think it was Android 10 but i'm not sure)
PS: I successfully downgraded/rooted some devices but as every brand has it's specific way to perform downgrade, i'm asking here. Any advice would help and i'm aware of dangers of downgrading/rooting devices (bricking). In any case, it would be awesome to also link unbricking guide for TB-J606L, just in case It's always better to have plan B.
Update: I found source of roms for my device but i can't recognize which versions are old Android 10 and which are the new Android 11.

Question OnePlus 9 Pro rooting. Can I use normal OxygenOS after root and couple other questions.

Hi. I am new on XDA-Developers forum and I am also trying root my phone first time and have some questions about it what maybe all have been here in forum already but asking still.
So I want root my phone (OnePlus 9 Pro, LE2121_11_C.61) and I want continue using OnePlus own OxygenOS. Is it possible?
If I have understand right I can continue use OxygenOS and there is no need for updating to use custom ROM after root. But when coming new updates for OxygenOS from OnePlus, then I need download and update it manually every time or have some kind of auto update feature or app?
If I want update to global version my 9Pro how it can do? Lose I all data in process? This is some Saudi Arabian version and I want Global or EU version or what ever else than Saudi.
This guide maybe best what is available and Magisk method is easiest for first timer?
How to Root OnePlus 9 Pro – Four Different METHODS!
Hello, today, in this article, I will show you how to Root OnePlus 9 Pro. This guide is very straightforward. You just have to follow the steps carefully.

1. Yes. I'm doing it now.
2. You will have to download the whole ROM and do a local update, then patch it with Magisk before rebooting to keep root. You'll patch the inactive slot. It'll change to that when it reboots.
3. It looks like you're using an A12 slot. I'm not familiar with your version. Under A11, you could use Oxygen Updater, download the version you want and flash it. Your data would remain. If you were on A12 and you downgraded to A11, you would lose your data.

Question I wish downgrade to Android 12 without root

Hello. I installed Android 13 and I am not satisfied. I would like to return to Android 12. I understood that it is possible to downgrade by downloading the related file for Android 12 which will be placed in the root directory of the phone and then downgrade from the local installation. Oneplus support told me that they are not allowed to help me... Can you help me with a link where I can download the official, stock version of Oxygen 12? Has anyone successfully done this before? Thank you.
