OP 7T Pro McLaren downgrade from android 12 - OnePlus 7T Pro (Regular & McLaren) Q & A

Hello guys, yesterday I made a huge mistake by updating my phone from android 11 to 12, the most important feature that I am missing and need so much is wifi calling, the network signal is very weak inside my house.
Is it possible to install back my old version of android 11? Tnx

It's still there on 12

Can i install android 6 or 7 or 8 on samsung a10s

Hey there I have rooted my android 10 to enable wps but unfortunately it is not working
So
I want to downgrade android version from 10 to any other version that supports wps connection
Can I and how ?
There is no way in how you could ever downgrade to a version, which was lower than the version the device was preshipped with. You cant downgrade a Galaxy S8 to 6.0.1 for example, as it was introduced with 7.0. Correct me if I am wrong but in my many years of experience, I have never seen something like that. I think the A10s was shipped with Android 9. There is no way how you can get Marshmallow/Nougat/Oreo on that Phone. Sorry!

Why NFC works only in Android 11?

I downgraded to android 9 and noticed that it isn't working. I have downgraded multiple times but it used to work.
If I update my phone to android 11 latest then it works again but I don't want to upgrade to 11.
what might be the issue? How do i fix it staying on Android 9?
NFC in settings cannot be toggled!
Thank you

If I flash any A11 Customized ROM it works.

Which custom rom!

Hi all,
I have a Huawei Honor 9. Recently replaced it's battery and still find that the phone in general has poor performance nowadays and not great battery life either.
The device currently runs android 9 on Huawei's EMUI v9.1.0 9.1.0.210 Android security patch 5 July 2019.
Please can you help me figure out if running a custom rom here makes sense, will get me any benefits and let's move from there?!

X96q Allwinner H313 Android 11 problems

Hi everyone,
I had good experience with X96q with Android 10, but yesterday i bought 2 X96q for others rooms in my house, but with Android 11, i had 2 problems :
-The play store stick with version 16, i did everything to update it to the last designed version (32) but no luck.
-We can't change launcher with this version, i installed the launcher, but it stays like an app. The system cannot detect the new launcher to ask us which launcher to choose.
If anyone faces these problems, is there any fix?
The last question, can i install Android 10 in this box which has already Android 11? Is there any risk to brick it?
Thanks for your help.

Question TWRP for those on Android 11 or downgraded + stable Gsi for use

Someone experienced could make a topic or a tutorial for those who want to get rid of One Ui on the A7 Lite, whether in the LTE or WIFI version, especially for those who have downgraded and are on Android 11 or have not yet updated. I would really appreciate it!
