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 ????

Downgrade from OOS 4.1.5 to 3.5.x

I am having serious battery drain on any OOS 4.x.x rom. I used to have very good battery life in 3.5.2. can anyone give me a proper step by step guide to downgrade? Battery is a huge issue for me.

i have my own steps that i found it by my self but it will earse all ur data so backup ur data to pc.
here are the steps :
1. make sure u have unlocked bootloader, custom recovery (twrp) i prefer use blu_spark twrp latest version
2. pur ur 3.5.x firmware in internal storage
3. boot to twrp recovery and do a clean wipe(dalvik, data, internal, system, cache)
4. flash ur 3.5.x firmware. it will take a long time just wait it
5. reboot to system, ull get a no os installed warning in twrp just reboot it(swipe)
6. when the devices boot up ull get a enter password for decrypt data. just reboot to bootloader
7. when u in fastboot mode connect ur devices to pc
8. use op3/op3t toolkit to flash twrp from fastboot u can find the toolkit here: https://forum.xda-developers.com/oneplus-3t/development/toolkit-oneplus-3t-toolkit-unlock-t3507729
9. then wait when it boot to twrp and when it boot up wipe data, internal storage only
10. reboot to system. done
sorry for my bad english. i hope it works

Ok that sounds easy. Reboot to recovery after flashing ROM retains the recovery I guess. Do you have any suggestion of custom kernel for 3.5.x ? Also i have the latest twrp. Will is allow me to flash 3.5?

Thank you guys. It wasn't really tough. Flashed OOS 3.5.4 full zip. Rebooted to recovery then rebooted to system. However it was bootloop at the start then I restarted and flashed SuperSU zip, it booted up. Don't know why SuperSU is required to boot up. However I am not getting the support for Magisk. I tried cleaning up SuperSU and then flashing the Magisk zip but it didn't work. Any advice ?

[Guide] Decrypt OnePlus 7 Pro

In this guide I will show you how to decrypt this phone
You might be asking:
(What are the advantages of decrypting?)
Well, it is much easier to switch between custom roms when you are decrypted and you don't have to wipe internal storage everytime you flash a new rom and there may be a performance increase (Maybe).
(What are the disadvantages of decrypting?)
If your phone gets stolen.. The stealer can access all of your data and can even remove the pattern by just rebooting to twrp and deleting a few files so your phone will not have any protection whatsoever.
Downloads:
Disable Dm-Verity
Magisk
Instructions:
1- You have to be on clean oos without any mods or kernels.
2- Reboot Recovery
3- Format data (Go to wipe - Format data and click yes)
4- Reboot Recovery
4- Flash No Verity Mod
5- Flash Magisk
6- Reboot System
Now you are decrypted!!
Keep Decrypt between OS updates:
-Reboot Recovery
-Flash FULL ZIP in TWRP
-Without booting the OS: Flash TWRP Recovery, reboot recovery, Flash No Verity Mod, Flash Magisk, Reboot System.
Keep Decrypt between Roms:
-Wipe Data only in twrp!!! (NEVER WIPE SYSTEM OR - VENDOR ON OP7P)
-Flash Rom
-Flash TWRP
-Reboot Recovery
-Flash any other zips you want like Gapps-Kernels- ex.....

Settings, security, down towards the bottom it tells you

OK so I'm encrypted... Am I secured somewhat from theft correct? And yes I know it's not 100% but it is safer than decrypted?
Another question let's say I don't mind being encrypted because I have a flash drive with otg and all that... Is that good enough? Or should I go decrypted all the way so I can start backing up on twrp and restoring twrp without errors which would mean no use for flash drive...
I know it's my choice just trying to make things easier and to understand a little more

If you are really concerned about your data and you are OK with wiping internal storage, then I don't recommend decrypting and just leave it encrypted.

I have oos decrypted via disable force encrypt!
Today I went through the following process to update to the latest version of OOS.
1. Flash full oos & twrp
2. reboot to recovery
3. Flash magisk
4. flash disable force encrypt
5. reboot
rebooted, but back to TWRP,,,
there was a "0" directory in sdcard and inside it my data was in it.
Do you know the solution?
thx

DFE is Disable Force Encryption also known as dmverity in some cases.
And yea you can reencrypt without losing data but it takes time depending on the size of files you have.

can we use this method for boot dual os (oos+custom) , when we install dual os twrp by @Zackptg5 we face problem with encryption and password protection on one of the os.
is it possible this method help this problem???

This does not work for my OP7Pro, when you say boot into Recovery and wipe data. Is that the stock recovery or TWRP? When I try decrypting using the instructions using TWRP, when I reboot the phone, it boots into the boot animation. But the animation is slow and the phone just gets stuck there and won't boot any further. Trying to decrypt so it's easier to get LineageOS installed. My phone seems to have problems when on the B partition reading the internal storage.

Are you running an open beta build? OnePlus did something dumb with the beta builds where this no longer works. I've been racking my brain trying to find a way to decrypt a beta too. For now, only the main builds of OOS are decryptable.

No, my phone was on a main build. Just wasn't having any luck and gave up. I'm on LineageOS now but spent an entire day trying to get that installed and working properly. Something was weird, slot A could read my internal storage, but when I switched to slot B the internal storage just disappeared. Once I got TWRP and LOS installed on both slots, the problem disappeared. But I still haven't attempted to decyrpt for fear of messing up my current setup.

I'm on OOS 11 Beta 1 and decryption works fine for me. I was on 10.3.7 (decrypted) before.

Do you have to be on OOS? Or could any clean flashed rom work?

who can help. i cant decrypt my op7t pro. Well, let's start with the fact that when formatting dalvik cache and data, I have an error and nothing is formatted. as with (Go to wipe - Format data and click yes). Formatted this data via adb, installed No Verity Mod and now I have bootloop

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.

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 just used the stock firmware .img file via fastboot. I restored 9.5.7 with no issues. Of course you'll lose all your data.

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.

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
Info for TMobile gm1915 on 9.5.11
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! ?

Just flash system.img via twrp. Don't need wipe system partition

update your magisk on stock to v25.2 to avoid a bootloop. only bother to install phh patched GSIs if they're A12 ones.
backup up apps and files, boot twrp and format data (not wipe). use reboot option in twrp to reboot recovery... don't skip this stage!! wipe cache and dalvik/art. flash extract image to system partition.
