problems with miui 11, downgrade to 10?

i have some issues with miui 11, as bluetooth, adaway, titanium backup stucks...
can i downgrade to miui10 or will i have brick problems?

What are the Bluetooth issues?

Mi-9, MIUI 11.0.5 Stable (QFAEUXM), Andoid 10, since the resent upgade the HotSpot data sharing feature does not work. Though previously i had my phone connected to my car system without any problems since the last upgrade my HotSpot is not regognized (found) even if i turn it as free (without any protection). I already tried to clear cache and reset all wifi, blutooth and Data settings but in no result so ever. I can connect my Samsung phone without any problem to the same of course car console.

@kok8 This is Mi 9 SE forum, not Mi 9.

Maybe it's a little late, but xiaomi has released a firmware to downgrade to miui 10. It is available from the telegram group "MIUI 11 Updates".
Has to be installed with "choose update package". I successfully downgraded mine, although you might not have eea version so I am not sure how much it affects the process.

Hi, I don't have telegram so I cant check it but does the firmware you talked about work on every device (I'm looking a way to rollback without unlocking bl on 9t pro) or is it specific to Mi 9/SE

Downgrade from android 10 and flash stock rom?

Hello.
I currently have PixelExperience ROM android 10 version installed on my phone. I have downloaded the india version of official fastboot image. How can I install it as Mi Flash tool shows "mismatching device name"
Kind regards
Ryuk

Redmi 6 pro has rollback protection so I don't know how it may end.

Why you want to go back to stock? Any particular issue?

your problem sounds more like data partition incompatibility
use CLEAN flash first (format data, not wipe) follow this tutorial
if it dosn't work, then start playing with FW
FW links
RN8 : https://xiaomifirmwareupdater.com/firmware/ginkgo/
RN8 T : https://xiaomifirmwareupdater.com/firmware/willow/
you can flash any region fw, (flash with recovery as normal zip)
just don't make mistake flashing ginkgo FW on willow or willow FW on ginkgo
you will break the phone !

Question HydrogenOS?

I have a Oneplus 9 pro which I bought from a chinese company in Hong Kong - Bludiode.com - I have been told it has Hydrogen OS on it but nothing says Hydrogen OS anywhere? It has just updated to Android 12 with a couple of updates recently. Is there any way I can check what it has on it. I always have been able to use Google and everything has worked well but the latest Android 12 has stopped the Amazon Alexa app working properly. Not fantastically worried but hey.
Where should I go from here? Some say change to OxygenOS but not sure if this is possible. Should I change to ColorOS and then OxygenOS? I'm in the UK.
Inspire me....

I'm a complete novice so please be gentle!! It says downgrade from OOS12 to OOS11. I don't have OOS12 - It's Hydrogen so is this the right file?

I have got as far as downloading the 2 files to the root BUT
The Local Upgrade as well as other system update options are not visible under the Update Settings page. So how do I install these? They don't install automatically and there is no way that I can see to install them?

OP 7T downgrade from stable Android 12 to Android 11 [EU version]?

Hi guys!
Just today, I updated my 7T [EU model] to the new, stable version of OxygenOS running on Android 12. However, I quickly realized that I much more prefer the old stable OxygenOS 11. Is there a way to downgrade to that version? I've tried scouting online, however, I only found downgrade links to Indian models.
Thanks very much!

Hi my friend!
Just check the official Oneplus forum (oneplus.net). There is a post OxygenOS 12 MP2 for Oneplus 7T/7TPRO that is pinned. There is a download link for all versions. Note that your cell phone will be erased!
Link: https://community.oneplus.com/thread?id=1181216999612088323&fromCircle=true

Thanks a lot, worked 100%

I just upgraded from 11 to 12, and i loose my connection every hour. Only thing that can bring back my signal is switch the phone into flightmode and back.
So will revert back to 11 as you did.
One questoin did the roll back wipe the phone or was apps and other settings still on the phone?

Is it possible to keep root through the rollback if I patch the boot image with Magisk before rebooting?
Edit: Just downgraded and had to root again after the downgrade (patched boot.img)

I am in the same situation. Upgraded to Android 12 and I'm having so many problems. I too am now downgrading. And actually moving away from OnePlus. Too many problems. Gonna try Carl's Nothing phone.

Hey there, Is it the original thread on offi OP site is not available anymore.
Do You guys remember the steps and what was needed to do the downgrade by chance ?
Help appreciated.
