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 ????
I flashed TWRP with succes according to cmd. But when booting to recovery it gives me the stock recovery. I had the same problem with my OPX. Someone on here said that MM had a new bootloader so i had a TWRP that was compatible with that bootloader. Is this the same for OP3T? If so can anyone link this

flash twrp 3.0.4.0 (in OP3 forums, now unified), from fastboot boot immediately to recovery it should boot TWRP, flash SuperSU or similar (or kernel that will rename stock recovery) to keep TWRP, reboot recovery from TWRP to check it works, reboot to system and profit.
if you don't root, stock recovery will keep coming back.
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 ?

You have to reflash stock boot image to get Magisk to work
My phone M2102K1G came with IN ROM as I bought the phone in India during launch.
I unlocked bootloader and flashed Xiaomi.eu's fastboot ROM which is based on CN ROM and my model was then M2102M1C. I didn't like the Xiaomi.eu ROM and switched to Global MI fastboot Rom. Rooted as well. Very happy with this
I did not fastboot flash TWRP and left my phone on stock recovery. I have tested fastboot boot TWRP and that works well though the initial language (TWRP) is Chinese and you have to first switch the language to English. I haven't flashed anything via TWRP as yet.
My question is:
OTA zip file (Global MI Rom)
Can i flash it via TWRP?
Even though my phone is for the India IN region?
And if I can flash it via TWRP, then do I immediately flash with Magisk zip as well to keep root?
Thanks to anyone who had the patience to read through this and can hopefully reply.
In case you want update a stock ROM without TWRP and keep root throughout the updates here is my guide to do so.
Download on your phone latest recovery package manually from trusted websites. You can find the ROMs and firmware specific for your device on here https://xiaomifirmwareupdater.com/miui/star/ remember to download the recovery version
Disable magisk modules and reboot
Upon reboot go to settings->system version->Miui(top left button)-> in the updater click several times on the main icon to unlock hidden settings->once unlocked tap on the three dots on the top right and select "choose update package"->browse your folder to find the downloaded recovery package,select it and press the V button on the bottom->update will start->wait until completion and reboot
Once rebooted follow the procedure to flash magisk.zip
Reboot the phone into fastboot
Connect phone to the pc
Boot into twrp
Once in twrp flash dalvik and cache
Flash magisk.zip and rewipe dalvik and cache
Reboot system and voila

Ok thanks.
I'm definitely gonna follow these steps the next time I get an OTA update.
Don't need to be rooted to flash boot TWRP is it?
No, you don't need,but you don't flash twrp, you just boot into twrp
If I have a unlocked and rooted phone with stock recovery, what happens if I just update normally via the stock update procedure? Will it not work?
Without disabling Magisk or anything and just updating.
Honestly I don't know but I can say that magisk wasn't fully working after updating without reflashing it
Okay.
So I cannot flash the OTA zip.
But have to update using the full recovery ROM for the updated version.
And then flash Magisk via fastboot boot TWRP

How will I get boot.img from the recovery ROM?
Only fastboot ROM will have boot.img
I think you have a bit of confusion, only thing you have to di is download magisk.zip on your phone, boot into twrp and flash it, simple

Yes, you will probably have to reinstall Magisk as root will more than likely be broken. The update server still sees a stock rom and as long as you have stock recovery, the stock OTAs will work.
The guide posted above explains properly the steps. Will try that next time around.
Hello together,
I have the problem that TWRP is disappeared after a restart. I installed TWRP with this steps:
1. adb reboot bootloader
2. fastboot flash recovery recovery-TWRP-3.3.2B-0302-XIAOMI_CC9-CN-wzsx150.img
3. fastboot oem reboot-recovery
TWRP is now installed, but after a reboot the default recovery is back. I had the problem before and therefore installed Magisk from TWRP. This was the only way TWRP was preserved as a recovery. I don't want Magisk anymore because I don't want root.
Thanks in advance

if u are in miui stock rom, this always happens, try to decrypt or flash every time u need the custom recovery. Stock rom always back to stock recovery
