Downgrade OxygenOS from 3.5.2 to 3.2.6 with Root / Xposed / Debloat

So I downgraded my Oneplus 3 from 3.5.2 to 3.2.6 and this was kind of a painful process, so I decided to share my experience with you.
If you follow this guide you will successfully downgrade from the latest Community Build to the newly released stable.
Note: Just because this worked for me, doesn't mean that it will work for you! Use this guide on your own risk and always use backups!
You'll need:
- Oneplus with OOS 3.5.2 and modified TWRP
- OxygenOS 3.2.6 Full ROM
- Latest official TWRP
- AndroidSDKSlim (needs Oneplus 3 USB drivers installed)
- SuperSU 2.78 SR1
- Xposed Framework (optional)
- Debloat Script (optional)
Downgrade:
Before you start, please create a COMPLETE backup of all your data.
You will factory reset your phone during the process.
1. Copy OOS 3.2.6 Full ROM, SuperSU, Xposed, Debloat Script to your Oneplus
2. Flash modified TWRP if you haven't already
3. Boot into modified TWRP
4. Select Wipe -> Advanced Wipe -> Select all but internal storage -> Swipe to Wipe
5. Install OOS 3.2.6 Full ROM
6. Reboot into system and use the installation wizard to setup your phone (do not setup fingerprints, or any device PIN)
7. Reboot into bootloader
8. Connect your phone to a PC/Notebook
9. Extract AndroidSDKSlim to your Desktop and copy twrp-3.0.2-1-oneplus3.img into \AndroidSDKSlim\android-sdk-windows\platform-tools
10. Run CMD with admin rights and navigate to \AndroidSDKSlim\android-sdk-windows\platform-tools
11. Run "fastboot flash recovery twrp-3.0.2-1-oneplus3.img" to revert to official TWRP recovery
12. Disconnect your phone and boot into recovery
13. Dirty flash OOS 3.2.6 again (this might sound stupid but it's mandatory)
14. Still in recovery, flash SuperSU, Xposed and Debloat Script
15. Wipe Dalvik & Cache
16. Reboot into system and setup your phone

Thanks for your guide !
Can you just please detail how to revert back to a custom ROM like RR or Nuclear when we come from Oxygen OS 3.5.2 community build ?

You're welcome.
Unfortunately, I can't provide guides for procedures I never went through.
But I asume that you could just flash any Custom ROM after you completely wiped your phone in step 4. So instead of flashing OOS 3.2.6 afterwards, just flash a custom ROM. Be sure that you have all zips you need on your internal storage and a backup to revert back to, if anything goes wrong. Otherwise you will have to use ADB sideload to install a ROM.

Ok, so I have a Modified TWRP installed already. Question is If I want to flash other ROMS after wiping system,dalvik/cache,data etc. Do I have to Flash official TWRP first followed by firmware,ROM, etc?
or firmware first then ROM and lastly official TWRP?
it's quite confusing.

I made a mistake and I installed the modified recovery installed the 3.5.2 rom and before booting I decided to restore my nand backup so I flashed the official twrp recovery and now I can't go to recovery anymore and the phone doesn't boot.
I imagine I have to sideload the modified twrp again but how do I do that? How do I reboot to bootloader ?
This is the only sign of life

worked like magic. Thankyou for this education. it didnt work when i followed other folks. Much appreciated.

So it seems I have booted with 3.5.2 and modified recovery. Now my question is: can I reboot in recovery at step 7 and install the original twrp recovery? Or can I use flashify? As I don't have access to a pc

I did ok but cant use adaway do you have a fix for it?

I'm trying to return to 3.2.6 after trying 3.5.2.
However, after flashing and booting 3.2.6, I boot into fastboot mode and the official TWRP refuses to flash. It reports that it's failed and then I'm left with no recovery until I reflash the modified TWRP.
I could try restoring my Nandroid backup of 3.2.6 with the modified TWRP, but I'd prefer to return to the official TWRP before doing this.
Any suggestions?
Edit: Fixed it. I downloaded the official TWRP again and it flashed. The first download must have been corrupted.

I followed a different method and successfully downgraded today to a former nandroid. I was rooted without xposed.
3.2.6 to 3.5.2 dirty flash
- installed modded twrp
- performed backup on 3.2.6
- installed modded 3.5.2 (the only that flashes in twrp)
- installed root SR1
- wiped caches only
- reboot
3.5.2 to 3.2.6 restore
- downloaded 3.2.6
- boot to modded twrp, wipe both caches, data, system
- flashed 3.2.6 stock and root SR1
- restored 3.2.6
- wiped caches
- reboot
- enjoying my LTE again
Without first installing stock, after a restore my phone was boot locking right after the oneplus white logo (capacitive buttons would light up, but it would not boot to red logo). Had to press vol down and power to force it to boot menu to select recovery and get back to twrp
Hope this helps someone, it's a bit easier than swapping twrps and no need to boot up/flash 3.2.x twice.

So if I am on the CB and want to go back to 3.2.6
I can flash 3.2.6 with the modded TWRP
Then flash Official TWRP and boot?

If I have official recovery, no root, and locked bootloader, can I downgrade from 3.5.3 to 3.2.6 without any problems, just by sideloading the zip in ADB? Thankss

I did it and it does work perfectly. Just make sure to wipe data from recovery after flashing.

I was on Comunity Build v.3.5.4. I want it back FreeDom v.1.6.
I did:
1. Flash Twrp-3.0.2-19-oneplus3.img.zip. Somebody sugested original twrp 3.0.2.1 from twrp site. For me did NOT work. Phone not booting in recovery with 3021.
2. Advanced wipe. Wipe dalvik cache/cache/system/data
3. Flash Freedom v.1.6. Clean Flash it's safer & better.
Done. System works. Recovery works.

1. If system don't boot. Reboot to fastboot.
- Flash recovery.img. If PC don't see youre phone option 2.
2. If system boots, open phone like normal.
- Extract recovery img. Put it on the TWRP file on phone sd card.
- Download Flashify from play. Open it, flash img of recovery. Open recovery to chech if it works.
Try with both recovery (3.0.2.0 or modified 3.0.2.-19). One of those will work.

Im getting system partition has unexpected contents after OTA update after installing step 5 ????

[ROOT] MediaPad M3 10 BAH-L09 Success!

First- I am NOT Responsible if you brick your Device! You do everything at your own Risk!
As I cannot find successfull thread here guiding to root this tablet I am posting the success with rooting with Magisk, all is seen on Russian forum 4pda,but the firmware I am on is not here ,it was little hard to find it(paid) but at the end it works, I have full root:
1 .You must have UNLOCKED BOOTLOADER!!! You can do it here are 2 threads guiding to it,mine was with DC_unlocker-4USD;
2. You must download Magisk from its original thread :Link
3.You must Look at which firmware you are,download the patched ones :С170B003
С170B253
C100B270
Or you can download you full Rom, extract it using Huawei Firmware Extractor extract the BOOT.img from UPDATE.APP file transfer it to your tablet and using Magisk--> install choose boot.img and patch it, then copy the patched_boot.img from folder "Downloads" in the internal memory back to PC,rename to boot.img.
4.You must have installed ADB and fastboot.
5.Using fastboot command on PC install the patched boot.img to tablet:
-First on your tablet enable Developer Options, thick Enable OEM Unlock,thick USB Debugging on,when connected to PC must ask for Fingerprint Security Rsa key,thick Always Trust to this PC"
-Second Tunoff Tablet, then hold volume Down button and connect to PC with USB Cable,Fastboot menu must appear: With green at bottom must be written that it is not FRP locked! If so -dont do proceed disable remove Huawei Account if you have one!
-Third-copy patched boot.img to folder where is located ADB and fastboot, then hold shift and right click mouse button and click Open Command Prompt here.
Now on fastboot menu enter following:
fastboot.exe flash boot boot.img
At the end everything must be OK!
Reboot with power button and check in Magisk !
Regards

I just wanted to confirm that this method works for my tablet. My Huawei Mediapad M3 10.1" BAH-L09 had bootloader unlocked. Emui5.1.2 and OS 7.0. Following these instructions, I extracted the BOOT.img from the stock ROM, then used Magisk Manager app (6.0.1) to create the patched-boot.img. Flashing this patched-boot.img using fastboot mode with command:
fastboot flash boot patched_boot.img
My tablet now is ROOTED without any problems (camera works normally). In short, just follow exactly these instructions and your tablet will be ROOTED

This works for me on BAH-L09 with Build Number BAH-L09C100B270. My Tab ist now rooted with Magisk 17.1 installed. Next i do flash special version of TWRP from the TWRP Builder site. I took the version for the BAH-W09 (WIFI version of the tab) on my own risk. I KNOW thats not the correct version, so please dont criticize.
Installation via fastboot worked. I can boot into Huawei recovery (Power+Vol-up) and TWRP (Power + Vol-Up and Vol-down same time). System boots without problem too. Also i can flash back the original huawei rcovery.img in fastboot mode.
But there is an issue in this TWRP recovery version 3.2.1-0. It does not decrypt data. I tried to format data and flash "no-verity-opt-encrypt". But there is still an Huawei secure mechanism, that wants me to format data in Huawei recovery again. Without format data my tab do not boot into system.
Next step i tried to get TWRP for my device on TWRP-builder app. but no succes because the build queue ist full. So i have to wait...

Sorry but how did you unlock the bootloader?

My M3 10 lite was on latest frmware C100B270 as i used dc-unlocker. Unlock worked well for me.

Does rooting enable you to install Google Services on the tablet? Is so, how?
Is there an international ROM that can be used (with Google tools)

Thanks! Worked for my Mediapad M3 lite 10 (BAH-L09), but now... How can I update Magisk? The Magisk manager doesn't support the version installed.
Can't install twrp either

This is an old post. Development has going forward. Look here:
For a LineageOS rom
https://forum.xda-developers.com/mediapad-m3/development/rom-t3945684
For TWRP
https://forum.xda-developers.com/mediapad-m3/development/twrp-t3914531
For the first step use the 3.2.0 version of TWRP if you are in Huawei's stock Rom.
For me its the best for this moment. Only issue is, that camera dont work in this early lineage rom. But developer is working on it.

I'm not newbe I did a lot of flashing on my previus phones Nexus and others. But this time I feel lost. I sit on miui 10 global stable. When I try to to flash twrp I get reroll to mi recovery every single time. All guides I found in the Internet are dedicated to older android versions. Xiaomitool don't help too.
Can someone point me to the right direction? It is time to change rom on my Mi5 finally to give him boost b4 I buy something new.
Best regards

Your bootloader is unlocked, right?
Then you need reboot to fastboot mode and flash latest official twrp via fastboot.
Like
Code:
fastboot flash recovery <path to twrp.img>
Have you tried it that way?

Bootloader is unlocked.
I did it that way but after twrp is installed I reboot and there is no twrp available. Only mi recovery.
To make it easier...
I would like to:
Flash twrp
Flash magisk and root
Flash firmware (why i need this?) Havoc os asks to flash it but I don't know why.
Flash havock os and gapps
Flash some mods for camera and sound
I don't understeand why twrp can't be flashed and I have no idea what is modified firmware for? Do I need this?
Thanks for your time

Try the the xiaomi eu rom guide .
I think you may need its custom bootloader , not the actual rom.
Than flash the firmware required for your custom rom and reboot directly to recovery again from twrp than rom and gapps , I hope that helps

Hi, i had the same problem, try this:
1. Flash twrp as usual(fastboot flash recovery twrp.img and then fastboot reboot)
2. When rebooting, you have to enter at recovery (vol up + power) . Don't allow phone to boot! In TWRP official page, on installation instructions , they say after installation you must enter in recovery to allow TWRP patch recovery rom, because some Roms after boot reinstall original recovery.
3. Now you should have TWRP installed.

If you do
fastboot flash recovery twrp.img
and then do
fastboot boot twrp.img
It's simpler and it will boot to recovery and patch the ROM to be permanently installed.

First,fastboot flash recovery twrp.img
and then no reboot your phone, just to hold the key combo (vol up + power), and then you can enter the twrp mode once because the recovery will be changed when your phone has rebooted.
But you can use the only once twrp mode to install the zip .
If you just want to use MIUI 10, you will flashboot twrp everytime when you need twrp to do something.
PS: Forgive me pool English.

Not sure if that will do the trick tho.
How are you installing magisk without any official or unofficial twrp???

Sorry i try to take link in here but this stupid server rules... "To prevent spam on the XDA forums, ALL new users prevented from posting outside links in their messages. After approximately 10 posts, you will be able to post outside links. Thank you for understanding!"
Go to miuios.cz to section redmi 8/8A, post MIUI CZ SK ROM + TWRP, you must be loged and in VMach3 post is this link.

I have only tried to boot mentioned recovery, but it was not working for me.

downloading 'boot.img'...
OKAY [ 2.107s]
booting...

After automatic reboot started system. When manualy restarted phone booted to vendor recovery mode. No adb was available and any try to boot to system was failure - phone always booted to recovery mode. To boot to system I needed to select "wipe data" and then reboot to phone (but all previous data/configuration was deleted).

One more try with this Unofficial TWRP 3.3.1-1127 for REDMI 8 by wzsx150, this time it was success, everything was working smoothly.

TWRP is language and version (global, china etc.) neutral. You have on first screen by first run button on right side at the bottom where you can select english language.

If you want root your phone with magisk, go directly to canary version. By stable version I got root only by adb, other apps were denied root access and freeze for a short time (for ex. Total commander beta).
On the other hand I was not able to use phone with not encrypted data with none of magisk version (stable or canary) even if I had "Preserve forced Encryption" unticked.
Code:
~$ adb shell getprop ro.crypto.state
encrypted
Tested on MIUI 11.0.4 by xiaomi.eu.

Unable to install official TWRP in Redmi 8, Miui 11.0.7. It installed. and then vanished when rebooted. and then boot looped. Had to flash original recovery and boot img to reboot.
Had made sure that I didn't boot to system after flashing TWRP. and boot to recovery instead. It flashed okay. Could use the root after installing Magisk. But on reboot, all was gone. Boot looped.

Hello,
Did you reboot via button combo or fastboot reboot?
I read somewhere that Magisk is to be flashed before reboot.
Anyway, you will succeed.
I follow you because I am at 100 h to unlock.

Remember I am not a developer, if you are presenting any bugs let us know and you can contact the Havoc team on Telegram
I am not responsible for any damage caused to your device by not following the steps or negligence at the time of this process, All the steps were carried out and tested on my personal device and are confirmed, My device Redmi 8 3/32, the version that i tested Havoc-OS-v4.5-20210208-Official-arm64-ab.img.xz
Bugs
videos recorded with the default camera do not play
Update: Install the NGCam_7.4.104-v1.8-fix.apk Once the application is installed open it take a photo close the application, this will create a folder in the SD called Gcam, inside the Gcam folder create a folder and call it Config7 and inside this place the XML file Redmi 8 GCam 7.4.104.314953318 G_Modder.xml restart the application and you're done
the only bugs that have is slow motion record not work for now
Automatic brightness does not work
Update: to fix the automatic brightness on your device, after installing the ROM, put in the folder SYSTEM-OVERLAY the treble-overlay-xiaomi-redmi 8.apk and set the permission for the apk on 644 ( use root explorer ) and reboot ..... problem solved
the necessary files are at the end of the tutorial
Steps
Note: I did the installation coming from Mui 12.EU, and there was no problem in the installation process or in the boot process
If you come from Miui12 .EU or any other GSI Rom go to step 4, if you come from the Rom stock follow the this steps
1- First make a backup of all the necessary information in case something goes wrong you can easily recover, Charge the battery at least 80%
All your data will be deleted during the process
2- Unlock the Bootloader if you have not already done it or do not know how to, follow this post: http://en.miui.com/unlock/
3- Install a custon recovery, if you dont know how to, follow this post: https://c.mi.com/thread-2850424-1-0.html
4- Make wipe only to Cache, Dalvik, System, Data and Internal SD
5- Format data,( if it doesn't format the data you will have bootloop) then Reboot into Recovery
6- Copy all the files to the phone (Havoc-OS-v4.X-20200522-Official-arm64-ab.img you can find it by unpacking the zip), Magisk,Magisk Path Fix, Permisiver, Certification Patch.zip, opengapp (recommended nano or pico)
7- Install system image to system partition (on TWRP go to install-Install image-System) .
8- Flash Permisiver v5 (on TWRP go to install selec permisver_v5.zip)
9- Resize system partition to flash opengapps (on TWRP go to Wipe-Advanced Wipe-Select System on the list-Repair or Change File System-Resize)
To Root
once you have installed an resized the system
10- Flash the Magisk path fix (on TWRP go to install selec MagiskA11_PATH_fix.zip)
11- Flash Magisk (on TWRP go to install selec Magisk-v23.0.zip)
12- Flash Opengapps
1-Flash Certification Patch
1 - Make a wipe to Cache and Dalvik
1- Reboot
The boot process takes 5 to 10 minutes the first boot, in case of any problem in any of the stages you can reinstall Miui version fastboot with Mi flash tool and start again

Hey !
I have a stupid question. Do you upload the GSI ROM and the other files on a SD card or on the internal storage ? I was searching this guide on the morning but I was wondering about that...
Thanks for your answer

You can place it in either of the two, as long as you can access the storage where you placed them from the recovery

Hi, I need to know some things to help you, what ROM did you have before flashing Havoc? do you have the bootloader unlocked? When did you use My flashtool, what method did you use?

In my particular case it was not necessary to flash vbmmeta as I comment in the OP I come from Miui12.eu, but it is necessary to avoid problems whatever the ROM you have before installing Havoc is to have the latest version of TWRP and have configured a lock pattern security in ROM access and in the flashing process I didn´t have problems

Hey!
I was on the stock ROM when i started to flash HavocOs.
I unbricked my phone with the MIUnlockTool V2 and my phone's still alive.
I booted on TWRP with fastboot boot TWRP.img 'cuz I can't boot to TWRP with volume up and power...
How can I flash HavocOs in the good way ?
I have Redmi 8 3/32 like you...

Ok the first thing is that you have the bootloader unlocked, if it is that way regardless of the stock version of the rom you have when installing twrp you must install magisk to ensure that the Recovery remains fixed in this link is a tutorial on how to install it, that tutorial was made by me and approved by Xiaomi https://c.mi.com/thread-2850424-1-0.html ,
install the latest version of TWRP and as it says in the tutorial then flash magisk, once you have everything ready install miui 12.eu do not do many settings except create a blocking pattern when starting the rom this is used by TWRP to be able to decrypt the internal memory
All ready do the steps as indicated in this tutorial (If you come from Miui12 .EU or any other GSI Rom go to step 4)
If for some reason you have a problem, use MI flashtool to return to the stock rom, but make sure to use the snapdragon method, select MIflash and when opening the screen at the bottom select clean all, this will prevent you from blocking the bootloader and you can start again without problems (note when selecting clean all at the end it will give you an error for not being able to block the bootloader and the device will restart, do not worry it will restart normally without problems)

Hey!
I thought about something this afternoon : if I flash HavocOS with adb and fastboot, we also haven't any problems with TWRP installation ! But the problem is that I haven't found any wiki to do that and i won't transform my phone to a beta tester....
Thanks a lot for your help but I think i will wait until a custom rom of LineageOs or HavocOs...

Hi . I am currently running havoc is 3.12 on my device I tried multiple times to flash this ROM without any success. Is not installing open gapps a problem ? Anyways when I flash this rom without flashing the certification patch I get a no os installed warning before rebooting from orange fox recovery but when I flash the certification I no longer get this message. Etherway I am getting stuck on a bootloop . How can I solve this issue? I did all the steps correctly wiping the correct partitions and formating data . Edit I wiped cache and dalvik after the bootloop without any success .

Hey !
I had the same bug before installing the v3.12 version.
I think it goes from the Permissiver v5. I think we should flash it to have the Havoc v4.
I'll test later if I have the time to do this and I'll inform you about the possibilities.
Hope I can help.

Thanks for replying and trying to help but last night I managed to get havoc 4.1 is installed by flashing lineage first (using another guide from this category). I will try again to get havoc 4.1 working without flashing lineage as soon as posible because I am curious .

Finally managed to flash Magisk on Havoc 4.1 with the help of youtuberking (telegram and YouTube).
How: just flash Magisk path fix before magisk and it's good to go.
