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 ????

[ROM] OxygenOS Open Beta 9 (Nougat) Update and Installation!!

Hi everyone,
We appreciate everyone’s feedback from the OxygenOS Open Beta 8. With your help, we have optimized and improved several key areas.
The changes include:
Added Expanded Screenshots
Shelf Design Optimizations
General UI Optimizations
DPI Optimizations
Battery Performance Optimizations
Stability and Performance Optimizations
General bug fixes
Please visit the download page here:
http://downloads.oneplus.net/oneplus-3/oneplus_3_oxygenos_openbeta_9/
If you’ve already flashed a previous Open Beta build, you will receive this update via OTA. If you haven’t, you will need to flash this build by ADB sideload. Your data may transfer, but there is always a possibility of losing personal data, so be sure to backup all of your important data before flashing this build. As stated before, once you flash the Open Beta, you’ll continue getting Open Beta OTAs.
Please follow the link below for the UI/UX experience survey. We’d really appreciate a few minutes of your time, as it will help us make OxygenOS even better. One last thing: this is a limited program, so we may disable this download link once we receive enough feedback.
- Feedback on UI/UX: https://goo.gl/forms/hEqMPq9U9QNrxvhc2
Note: If you flash this Open Beta build, you’ll receive Open Beta OTAs (but not official OTAs). You’ll need to manually (clean) flash back to our official builds to continue receiving official OTAs. Rolling back to official OxygenOS versions require wiping data and cache.
Thank you for your patience and as always, we look forward to hearing your continued feedback in the bug reporting forum here: https://forums.oneplus.net/feedback/.
Thank you for helping us build a better OxygenOS.
Never settle.

Installation Methods
Before we start:This method is only for the OnePlus 3
Follow the steps correctly otherwise you may brick your device. I am not responsible for any damage to your device, please ensure that your device is at least 60% charged to prevent the accidental shutdown in-between the update process.
Downloads:
Beta 9 Full Zip Official Download
Compatible Stock Recovery
********************* For Stock Non Rooted Users with Stock Recovery *****************
1. Download the appropriate OTA/Full Zip from above link and place it in the root folder.
2. Navigate to Settings > System Updates > Settings Icon > Local Upgrade & Select the OTA File
3. Once selected system would prompt upgrade now
4. Select upgrade now and system would reboot in stock recovery and flash the OTA
5. The installer would itself flash the OTA and reboot the device.
The Device will reboot and your OnePlus 3 is now running on the latest OxygenOS firmware & OS.
PS: The first boot may take some time so keep calm and wait for it to boot.
* After flash is successful go back to recovery and a wipe of cache is recommended.
* If in any case flash is unsuccessful the system would prompt you to download the full 1.4GB zip. So download that and follow the same process as above.
************************ For Rooted Users with TWRP Recovery ************************
Download Beta 9 Full Zip
1. Download the Beta 9 Full Zip on your phone internal memory.
2. Download the Latest SuperSU SR5
4. Reboot To TWRP (Modified 28) & Take a Nandroid of your existing ROM
5. Go to Wipe > Advance Wipe > Select Dalvik & Cache & Swipe to Wipe
6. Install Menu > Select Beta 9 Rom Zip > Swipe to Flash
7. Wipe Dalvik & Cache
8. Flash SuperSU to maintain root
9. Reboot System and Enjoy the Beta 9 Update
* Do not flash Xposed as not compatible with 7.0 builds yet
If you come from a custom rom, i recommend a clean flash and make sure you use the modified TWRP 3.0.2-1.28 as the official one is incompatible with the CB firmware yet.
PS: The first boot may take some time so keep calm and wait for it to boot and the system would boot twice due to flash of supersu so keep calm
PS: Rooted users may either flash the full Beta 9 Zip or they need to flash the previous full zip beta 8 first to overwrite system partition followed by the relevant Beta 9 OTA zip for a successful flash else just the OTA flash would fail with error 7 in TWRP

I was on TWRP (modded) and rooted. Installed the update (OTA) and now my phone just reboots to TWRP no matter what I do (I have even made a factory reset and reinstalled Beta8)

You can't install the ota update on TWRP recovery. You need the stock one.
Try reflashing TWRP recovery via fastboot and then flash open beta 9(not the ota)

Download the recovery at the bottom of the page.
http://downloads.oneplus.net/oneplus-3/oneplus_3_oxygenos_openbeta_9/
Copy it onto your phone with the this Open Beta 9 package.
Start up TWRP, format /dalvik, /cache, /system, /data.
Flash the Open Beta and clean the caches if asked.
Flash the original recovery from TWRP as recovery image, and restart your phone afterwards.
Your phone may boot into the new recovery, then show "Update failed", then do another restart, but after that mine was working.

flashing with twrp will result in recovery booting loop. after downloading ota simply reboot to recovery, download oneolusrecovery from ob9 page. transfer it to phone. select install image in twrp, select reocover, flash as recovery and reboot to recovery. itll show updating.. takes about 20mins

Will modified twrp also not work?

Really? The modified twrp doesnt work? I,ve read the thread in oneplus forum and some are saying it worked for them. :/
Edit: anyways, im on modified twrp, rooted, beta 8, can i dirty flash beta 9?

Using Modified TWRP

Dirty flashed over OB8, so far no issue's.
Did flash TWRP img after update in TWRP (just to be sure), first boot took a while tho.
Anyone tried supersu?

I have this from yesterday. I was on 3.2.8 from OnePlus site, dated 12.05.16.
Clean flash with TWRP 3.0.2-1.28, thanks to eng_stk. Flash the rom & SuperSU SR5 (if you want root). Refalsh recovery 3.0.2-1.28. Reboot to recovery. If it not works reflash recovery.
Then reboot to system.
I did not flash any mods. All it's ok.

Yep. Just make sure to have the full update and not the OTA one. Also, just in case make sure you have the TWRP img and super-su on your phone's memory to be able to flash them again

Any mirror for this? Full zip is downloading really slow and I've already stucked on twrp after OTA Need to dirty flash the full zip, but it is going to dowload around Christmas with that speed...

[Q] how to update after rooting (magisk) ?

Hello
I was on B180 (PRA-LX1C432) rooted with magisk
No updates available in settings/update firmware, but connecting to PC HiSuite B194 appeared (which seems to be for Honor 8 lite by the way). It downloaded it, pushed it to phe phone, but when rebooting it goes to twrp... so obviously I'm still on B180
I imagine we have to flash back stock recovery before updating ? And then twrp again, magisk flash, etc ?
Thanks !

About OTA over magisk I found that on P9 forum:
1) unroot by Magisk Uninstaller, find the download link in the post https://forum.xda-developers.com/sho...63&postcount=1
2) flash from TWRP original stock boot img
3) wipe Dalwik and Cache from TWRP
3) flash from fastboot original stock recovery
4) let it make OTA update but select in the System Update settings to use Full (not differential) update - it will not delete your apps and settings
maybe the safest way indeed...
But as I "catch" the full ota, maybe I can use fastboot to flash only system and boot, and the reflash magisk to patch new boot img ?
anyone ?

Nobody updated after root ??

Ok, this is what I did and happened:
- In TWRP, flash magisk uninstaller script: ERROR 1. After reboot magisk was still here. That was a bad start...
- So I opened magisk app, click Uninstall and then Complete Uninstall. After that I made a reboot as asked, and device rebooted twice.
- Then, went to download mode and flashed stock recovery. And reboot.
- Then went to settings/updates/download latest full ota. It downloaded but refused to start the install process claiming to free up more than 900MB... Nothing on my internal sdcard so I had to uninstall some apps... cool !
- Then it reboot and installed the update
- First boot took a while, I still have "this device cannot be trusted" on start, and OEM unlock in settings is grayed and ON, so I think the bootloader is still unlocked
- Theme and wallpapers were reset with the update
For now I don't have flashed back twrp neither magisk .

In the meantime have you flashed TRWP and Migistik ? And again: do you have still to update your signature or something went wrong in installing fw B194.
Lastly: what do you mean by "went to download mode and flashed"...

[SOLVED] TWRP bootloop after OTA update from Global V10.2.1.0 (PEAMIXM) with Magisk

Hello guys,
Yesterday I flashed my Mi 8 to get root permissions with Global V10.2.1.0 with Magisk 17.3, including Disable DM-Verity and Force Encrypt. Everything was working perfect, Magisk notified me about updating to v18, so I did, and MIUI notified me about an update (if I'm not mistaken, for 10.2.2.0).
MIUI downloaded the update and asked me to reboot to install it. It booted into TWRP and did the whole installation, apparently without issues, but then I restarted and it goes straight to TWRP.
I tried clearing cache/dalvik but nothing.
Every time I reboot and gets to TWRP, when I press the menu button to see the log, the last lines say:
Full SELinux support is present.
set_policy_failed:/datamisc
I don't know if this is relevant, but seeing a "failed" is not nice.
As an observation, the folder /data/system is full of folders, but the /system directly in root folder only has /usr/share/zoneinfo (I don't know if this is normal or not),
If the system updated to 10.2.2.0, would flashing to 10.2.1.0 set the ARB or it's safe for me to flash it again? Any ideas?
Thanks!

You need to flash Magisk again. Installing an OTA means you flash the stock boot.img so flash dm verity and magisk.

Update to DP4 from Official 9.5.11 with root and without data loss

Tried and tested method to update to DP4 with twrp and root working.
If you update to DP4 directly before installing twrp you will be stuck without twrp.
You need USB pendrive and otg for it.
Steps
1. Update your phone to latest available official version.
2. Boot to fastboot and install TWRP (of course you need boot loader unlocked)
3. Flash DP4 from Thumbrive (keep it in external storage only)
4. Flash Recivery TWRP.zip from thumb drive
5. Reboot recovery
5. Flash DP4 again followed by Twrp.zip
6. Reboot recovery and flash magisk and any other mods you need.
7. Reboot
If you followed every steps correctly you will have working TWRP and root on DP4.
I am using it since DP2 and never had issues.
Note. Since Q diesnt allow twrp to read internal storage you will need usb drive for flashing mod also.
I have uploaded a video with DP4 Features if you want to know about its features.
New features
1. Volte working
2. Names of themes changed
3. System UI settings changed
4. Fingerprint faster
5. Overall phone is faster now.
Removed google assistant swipe shortcut.

Too late for me I currently stuck with DP4 with no TWRP. any idea how can I get TWRP again. The fastboot command isn't working anymore.

You need to use msm tool for reverting to stock
Or Stock reset rom for downgrade.
Then follow my steps

Is there any way to downgrade without MSM tool? I have a Mac. Local update doesn't work. Thanks for the reply.

Try MP version from DP Version package via local upgrade.
This will be available once the official thread is created by oneplus.
Or you may try DP to MP version for DP3

I was able to install twrp and magisk on dp3, i think you can do it with dp4 aswell.
I just fastboot flash boot twrp.img , it says slot a ok, slot b fail.
So i switched active slots and reboot, which boots to twrp installed on other slot. While in twrp (which cannot access data) i installed twrp through adb, switched active slot and installed twrp again. Same for magisk 19.4 installer.
After installing twrp and magisk to both slots i switched active to B and rebooted, which took me to rooted dp4.
Hope that made any sense
Oh and while in twrp, i used twrp installer (latest) to install twrp to both slots.

why do you possibly need to flash the rom and twrp TWICE? shouldn't the usual upgrade process for a rom if you are already rooted still work?
Flash the Q rom
flash twrp
reboot to recovery
flash magisk?
don't understand the reason to flash both twrp and the rom 2 times as posted in the instructions
regardless, i followed the exact steps and it didn't work for me. i boot to a plain black screen and can't get past it. any ideas?

Can you elaborate on step 2? Do we flash twrp.zip the same as the other steps? or do we flash the twrp-installer?

1. Downloaded the 9.5.11 update from Oxygen Updater (DONT REBOOT)
2. Went to Settings\System\System Update and click on the wheel on upper right corner.
3. Select Local Upgrade, then install the update (DONT REBOOT)
*DO NOT REBOOT after applying the update.
4. Remove Magisk modules that may cause problems (Call Recording is one of them)
5. Launch Magisk, and click the first "install"
6. Choose the "Install to inactive slot (OTA)" option
7. Reboot once completed
8. Download TWRP (from another location) and then go into Magisk and install it, but ***DO NOT REBOOT!!***
9. Install Magisk again. Click Install, then select "Direct Install" option.
10. Reboot
Will this work for DP4 as well????

Downgrade using the rollback package, when I did it on Beta 3 it did not relock my bootloader.

1. Downloaded the 9.5.11 update from Oxygen Updater (DONT REBOOT)
2. Went to Settings\System\System Update and click on the wheel on upper right corner.
3. Select Local Upgrade, then install the update (DONT REBOOT)
*DO NOT REBOOT after applying the update.
4. Remove Magisk modules that may cause problems (Call Recording is one of them)
5. Launch Magisk, and click the first "install"
6. Choose the "Install to inactive slot (OTA)" option
7. Reboot once completed
8. Download TWRP (from another location) and then go into Magisk and install it, but ***DO NOT REBOOT!!***
9. Install Magisk again. Click Install, then select "Direct Install" option.
10. Reboot
Will this work for DP4 as well????

I don't think so - what I've read on Oneplus page, when you hit restart (after installing magisk) it will reboot and during that erase all data. then reboot again to system. So you cannot restart via system updater,, you need use TWRP to flash it, so i would stick to the 1st post instructions (including 2-times install t ocover both slots). But hey, ican be wrong, you can try and let us know, it would be easier for sure

Is this the only way to get root on DP4?

Simple way

You must have magisk installed.
Update through local upgrade method and don't reboot. Then go to magisk select modules hit + and find twrp installer install twrp and then choose install magisk choose install to inactive slot. Then reboot.
Data does not get wiped but fingerprints need to be added again.
Also twrp decryption does not work so best to keep otg USB with you with whatever you may want to flash.
You don't have to flash to both slots it's not necessary but do as you wish.

Yes

Hi, I followed all the steps in OP and didnt. using latest twrp and magisk 19.3 (stable)
Now my phone is still starting its first boot about 15 minutes.
Update:
Probably the problem: installed magisk modules.
Anyway after some research default twrp is'nt mounfing local storage. The latest custom TWRP is! So no issues with USB Anymore, just use local storage like u used to do! This is actualy the only way to use the Magisk uninstaller because you need to mount data for uninstalling magisk modules.

Anyway it took me a view hours of testing but now it works smooth! ?
