See if you can flash this from settings. It used to allow you to downgrade from Pie Beta. I'm not sure if it will work for Pie Official. You will most likely lose your data if you successfully flash this. So backup your stuff even before attempting this.
Or you can use the unbrick method to completely reflash your phone to 5.1.5 using MsmDownload Tool.

Download the 5.1.11 fastboot rom. Extract it. Open the folder you extracted and run flash-all-partitions-fastboot.bat
You see some things that look like errors but they aren't!! You have to have patients and just wait!!! When it completed it will say press any key. Then unplug phone and boot. You'll be on latest 8.1
Here's the link.

I did that and gave me a Qualcomm crashdump so had to flash back to 9.0 doing the same thing using 9.0 fastboot

Run the downgrade zip from the Open Beta 1 page

Hello
I also want to go back to android 8.1
In the phone settings in the local upgrade section, the old version is still available but the message "to avoid the failure of the start-up phase, no downgrading is allowed", is there a solution for to work around this problem?
Thank you all

If you're unlocked, flash it trough TWRP and format your storage.
If you're not, on a Sticky thread somewhere on this forum, you can get a rollback build (it's an Oreo build, the latest if i remember correctly, it's clearly called "rollback")
Edit : it's on this page : https://forum.xda-developers.com/oneplus-6/how-to/oneplus-6-mirrors-official-oxygen-os-t3792244

What issues are you all having with 9? I was on the BETA build when I first got the phone and had several issues.. but after downgrading to the recent stable build.. I haven't really had any issues..

Android 11 Red Magic Rom [FLASHGUIDE]

Hello again!
I saw a post where leipnacht provides a link to the public beta of Android R. (I let you here a drive link to download it faster).
I flashed it and it's working properly on my device. There is some bugs, but the most part of the things works without problems (Personally, I didn't face any bug itself (only a low noise with the vibration by the moment), but there are some comments in the page of bbs nubia about some problems with other things.
The previous conditions from where I update to Android R Red Magic Rom were using a GSI in the Android 10 chinese version of the rom. So, the steps I followed are:
1. In the recovery, wipe data, cache and dalvik. Also, format data.
2. Flash in the Android 10 TWRP the Android R rom.
3. Flash this NikGapps Package , Magisk Debug and DFE (Encrypt disabler in order to be able decrypt data in the recovery). I also flashed Permissive_5 but I think there is no need to do it.
4. Boot and enjoy.
I will attach all the files and some screenshots for those who want to take a see to the rom. Personally, I feel no changes in this version, but, as always, the performance is great and it runs really smooth. It's a beta version, so I hope more changes in the future.
P.D. In order to get safetynet passing, I used HideProps Config magisk module. There is no big issues with it, and everything is fixable
P.d.2. This rom has antiroll-back active, so if you want to go back to previous version, you will have to use the unbrick tool

Thanks for the update.
I have been planning to upgrade my Red Magic 3 to Android 10 (CN rom) for quite a while now. And its good to know A11 beta has arrived too.
Have you tried fps games on this device like pubg mobile, cod etc? Do they work properly ?
Also, I haven't even unlocked bootloader on my device. Can you proivde a better guide, to completely switch from global rom (stock) to A11 (beta) or A10 CN rom (stable).
Need links / guide for following items -
- Unlock bootloader
- Link of working twrp and steps to flash (should I change recovery after installing this beta?)
- Gapps and Magisk link (As I can't run this device without Google services).
It will be a huge help for me to get started.
Take your time with it (no rush).
Thanks in advance!!!

Hey!
No problem at all. I let you here two guides to migrate to the cn rom and even a gsi
Be careful and aware about what you are going to do, It's not specially difficult but you have to get ready all the files and tools in case of brick or bootloops.
Enjoy the flashing!

Thanks for the links. I am planning to update to stable A10 version for now.
I have few questions it be a huge help you could clear some of my doubts -
1. After unlocking bootloader I have to install TWRP (for gapps to run). So should I install TWRP after flashing CN rom ? or before ?
I am asking this because I read in some guides that only CN rom is custom recovery capable.
2. If you have run A10 stables before, does OTA updates require to be installed via TWRP only ?
Will I loose Gapps and Root access if I updated the ota directly from settings? And will every rom flash with TWRP clear my installed apps ?
Thanks in advance for helping!!. ??

Well, I will go in order:
1. You have to flash first in the stock recovery the Android 10 CN rom and then flash the custom recovery. There is no twrp avaible for global rom. Once in the custom recovery, you can flash Gapps and Magisk (in android 10 there is no need of DFE file, the recovery is able to decrypt data properly.
2. You don't need to get worried about OTAs, there is no a constant software update work by nubia for this device, but in case of update, you would flash the rom from the offcial page, with magisk and gapps again and be sure you keep the custom recovery.

Oh! Didn't expect that. I just post this for Red Magic 3 device users. I don't know how RM3S actually works. Have you tried the unbrick tool from chinese version? Or just flashing the global rom from recovery is enough?

Wait is there a chinese unbrick tool cn. version for red magic can you provide me a link.. unbrick tool 3/3s.global by jerry is not working anymore if you got brick by android 11 beta rom...

Let's see. Here is a link for Red Magic 3S unbrick tool. Download the non-eu ones.
If you have a Red Magic 3 with Red Magic 3s software, I will provide you the link to the other unbrick tool.
Also, you can try flashing the global rom from the stock recovery included in the package of the A11 rom that you have download.

Thanks for replying my bro.. my device is rm3s i already use rm3 and rm3s unbrick tool.. downloading fire hose programmer and image was successfully but.. my phone is still corrupted... And one thingg i dont have twrp install in my rm3s thats why its hard for me to fix it.. can you please guide or teach me how to flash stock recovery using global rom i know how to use cmd and adb

So then, It's not a problem of the unbrick tool, that is actually working properly. The thing is that you didn't know how to do a correct process to migrate from cm rom to global...
The first thing you should do is reboot the phone into fastboot mode (power+vol. Down). Then, connect the phone to the PC and type the next commands in the cmd:
Code:
fastboot devices
in order to see if your device is being recognized
Code:
fastboot oem nubia_unlock NUBIA_NX629J
to unlock the bootloader
Code:
fastboot flashing unlock
in order to make your phone able to boot with a modified software. In the moment you will enter this command, you will see a screen advising you about your data (it'll be erased once you accept to unlock flashing).
After that, you can reboot your phone, that will show you an screen advising you that the bootloader is open. Accept and continue without problems.
Tell me if you have been able to make your phone boot.

Need help - oneplus 8t stuck in bootloop after flashing a wrong boot file

Hi all,
I tried to root my new oneplus 8t but stupidly enough i downloaded and used a wrong stock boot image (i need EU but used global).
Now my phone is stuck in bootloop, can someone assist please?
Or maybe someone can share with me a working patched file for EU (as i can't do that as my phone is not responsive anymore).
I tried to do so with magisk app.
Thanks in advance!

Have your tried flashing the correct boot image? If all you did was flash the incorrect boot image then that should fix the problem.

In order to flash the correct one, i need to transfer it to the device and use magisk.
The problem is that the device stuck in boot loop so i can't do that.
That's why i asked if someone has already patched Europe version to share with me or any other option for me to fix it

Here is a collection of stock boot images (if you don't trust them, just extract it using a payload dumper from the ota zip that can be found in other threads)

Download the stock boot image of all OxygenOS versions for the OnePlus 8T. Also learn how to flash a boot image on OnePlus 8T using Fastboot and TWRP.

There is no other tool or method that will resolve your issue.
If you follow the instructions correctly it will work.

Android 11 and OOS11 OnePlus 7 Pro

Hello,
I have scoured the forums ever since the update to try and get back to where I was, with TWRP, and a rooted phone. TWRP is not as important as root is.
I saw that there is a way to get root if following these instructions:
Rooting OP7 Pro OOS11
Where can i find instructions to root my phone having Android 11?
forum.xda-developers.com
However, are there any specifics or edge cases I need to be aware of? For example, if I am on the newest update versus the first beta update that rolled around a few months ago? At what point on Android 11 and OOS 11 do these instructions not work?
And I was wondering if someone can please provide some links to make it a bit easier for me (of the boot.img file and other things?), I actually leave the country in a week and so I really want to get this done before I leave, it would really make my life easier
Is there a way I can root without wiping my phone? And if I have to wipe, is there an app similar to Titanium Backup that's reliable that I would be able to use without root and restore some important data of apps?
Thank you!! Any help is appreciated

It's pretty simple. You just need to make sure you flash a patched boot image from the same build your device is on. The OP7 Pro forum is not very organized, and most of the available boot images are gdrive links buried in threads.
If you just so happen to be using the T-Mobile OP7 Pro, then I can help you. Otherwise you'll need to search around for a boot image for your device.
If you can get your hands on a stock boot image, you can copy it to your phone's SD card and use the Magisk Manager app to patch it. It will put the patched boot image in your phone's downloads folder. copy that to your PC and then use fastboot to flash it to your active boot partition

Yes it is. The boot image linked in this thread is exactly what you need. Flashing boot will not affect your system image or user data.

So after I download this boot image, I flash it using fastboot?
Because TWRP isn't available right?
Then after that, what do I do to root it?
Download the latest magisk?
Do I download the apk or flash that too using fastboot?

Question ROM on Samsung A12 (SM-A127M).

Hello, I have the SM-A127M.
I have been able to do the following:
1.Unlock the Bootloader.
2. Root with Magisk.
But I want to follow this Guide "Installing TWRP and LInageOS" and I have the following questions:
1. Is it possible to install LineageOS on SM-A127M?
2. Is there a version of TWRP for Android 11 on the SM-A127M? Download a version to install with Odin as AP from here: https://eu.dl.twrp.me/a12/
But the only thing it did was go into an infinite loop in Download mode. Lucky that I was able to unbrick it by flashing the full firmware.
3. Is the reason for switching to LineageOS to improve the phone's performance, do those who already have it really feel an improvement in performance or is it the same as using it with Stock Android from Samsung?
Thank you for your answers.

Don't bother bro, nobody responds to the A127M variant, I got the same phone and a few post before yours i wonder to a custom rom and no one reply.

I think so. Have you tried this model using the installation guides on the forum to install TWRP and/or LineageOS? Have they worked for you? Have they failed you? It does not matter if it is for this specific model.

no my mate, I don't do that for fear to brick the device 'cause it's my main phone and the backup phone have a issue with the battery. Thanks for the suggest.

I have the same phone, but i searched for a12s(sm-a127f) because the specs are the same

The physwizz dev have all on his channel. Twrp kernel etc... I've tried the twrp for this phone and it works well.

Twrp is fine but LineageOS no dont you cant call or text at all sometimes the sim isnt recognised even mention it in the sub reddit and everyone screams at you to download the official even though it happens on official builds

[ODIN] If you couldn't install it on AP, try to install it on BL.
