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 ????
Hello out there,
my problem is a bit annoying. Everything is fine if I use my OP3T with Oxygen (4.0.3) and TWRP (3.0.3-1). But I want to use LineageOS with TWRP and cant, because my TWRP isnt working after flashing lineage.
"Normal"-Setup:
- TWRP 3.0.3-1
- Oxygen 4.0.2 or 4.0.3 (doesn't matter)
- supersu 2.79
- Encrypted Device
"Lineage"-Setup:
- TWRP 3.0.3-1
- lineageOS (lineage-14.1-20170214-nightly-oneplus3-signed.zip OR lineage-14.1-20170208-nightly-oneplus3-signed.zip - tried both, doesnt matter)
- supersu 2.79
- openGApps for 7.1 nano
- Encrypted Device
My Problem is, that I can boot up lineage and use it, but if I reboot into my TWRP to flash something or make some Backups, it asks for my encryption-passphrase, it says it is okay and boots into the twrp main-windows. After that I can't touch anything (stuck in mainmenu) and after a few seconds it results into a black screen (plus white LED) and I am forced to reboot the device. After that reboot I have to reconfigure lineage (seems to loose data).
Does anyone have an idea how to fix this annoying "bug"?
Thank you very much!
Atomique
EDIT: I found that Thread after searching for a issue like that in the lineageOS official Thread - I will try this and report! - Thank you! https://forum.xda-developers.com/on.../recovery-official-twrp-oneplus-3-3t-t3543391
I had the exact same problem when I hab LineageOS installed! It would always lose all its data. After flashing and reflashing a hundred times, I ended up reverting my OP3T back to stock using a OnePlus forum guide (I'm a new user, so I can't post the link). I am now back to OOS 4.0.3 but can't even get SuperSU to work. Whenever I flash it (with or without the dm-verity fix) the phone is stuck booting forever.
I found the post you linked to aswell but haven't tried flashing LineageOS using the new TWRP. But I can tell that the new version doesn't help rooting OOS...
Did you have any luck flashing LineageOS by now?
Edit: With the newest Lineage Version I always get an error when trying to flash it. Do you have the same problem? The nightly from two weeks ago seems to work better.
Use latest TWRP 3.0.4.1

That's what I'm doing... Could the dm-verity be a problem? There are two versions, one with opt and one with force in the name.
Thank you for your replies! The link (TWRP 3.0.4-1) worked like a charme!
@Tafelbomber: I would recommend you to start from scratch. But please be warned: you will loose your data! Make a backup first!
1. Delete everything with fastboot -w
2. Flash the recovery noted in my first post with fastboot flash recovery <twrp-filename.img>
3. Optional: Restart into the TWRP and flash the OOS 4.0.3 to make sure that you have a clean OS installed befor flashing lineage
4. Flash lineage OS + additional ZIPs (like supersu, betterbatterystats, Gapps etc)
5. Clean Dalvik and Cache!
6. Reboot and have fun. --> Sometimes you get problems with the encryption chain (Red Error --> in my case the fastboot -w did it for me)
Good luck - I will close this thread - thanks again for your help!

EDIT: I want to close this thread, but I don't know how.
Can anyone help me with the steps to update to Android Oreo (OOS 5) from OOS 4.5.1 retaining root?
Below are the current setup of my phone
Rooted - Yes (Magisk version 14.0)
Recovery - TWRP version 3.1.1-2
Current Rom - Stock OOS 4.5.1
I haven't had any problems in updating earlier but now when I try to flash the full oreo rom from TWRP, I am getting error 7.
Below are the steps I followed.
Downloaded the full OTA zip.
Rebooted to recovery.
Unistalled Magisk.
Tried to flash the Oreo OTA zip. At this point TWRP showed error 7.
Reinstalled Magisk and rebooted to system.
Phone is working fine.
you need to use latest twrp for oreo, for example blue spark version, search for it on xda...
Follow this guide here:
https://forums.oneplus.net/threads/how-to-install-oos-5-0-over-rooted-4-5-1.684519/#post-17134194
It's exactly what you need.
All Oreo ROM threads clearly state under the "Instructions" heading, that you need either AkhilNarangs Modified TWRP or Blu_Sparks TWRP V50. Using stock TWRP would result in an error.
If the error may still persist, try flashing a different firmware.
Just to get some more clarity.
I have the original OTA full zip. Should I download the zip file from your thread?
Can I install the custom version of TWRP using the official TWRP app? I am bit confused on how to install it.
Is it important that I should use Magisk 14.3 or will v 14 have the same effect?
Hey there,
I can tell you how I have done it yesterday (successfully).
1. Update TWRP - I prefer blu sparks version 8.52 (Link: https://forum.xda-developers.com/devdb/project/dl/?id=27225); you can do it by using your installed TWRP Version (Install .img)
2. Dirty flash OOS 4.5.1 again (to remove root / magisk) - once finished DO NOT reboot into system, reboot into Recovery/TWRP to verify the new version and afterwards to system
3. flash OOS 5.0 (Oreo) - dirty flash is okay
4. flash magisk Version 14.3
These are the steps I have followed yesterday and all is running perfect and without any problems.
BR
Which recovery is mentioned in this linked discussion resp. in the linked download? Is it blu_spark TWRP?
Regards
Clark
This worked perfectly for me.
Glad to hear that everything is good ?
I did the same and I was suddenly encrypted and no chance to get my data back. Still forcing clean my phone because I cannot format the device. I get always an error message in TWRP like: unable to format to remove encryption
I go crazy...
Enter recovery and wipe data and then cache.
Then reflash the rom and probably you will be good to go.

Their is only one way to recover your phone just follow this step
1. Flash stock firmware(stock rom) vie fastboot using MI Flasher
this is bring back you phone and if you want to install custom rom then follow this
1. boot twrp
2. wipe all the data from slot A and B partition(internal storage as per you choice )
3. boot to slot B and copy past the custom rom file in slot B
4. flash that rom and boot to slot B and then flash Gaaps and other staff you want
5. reboot and enjoy.
NOTE: changing the slot require reboot twrp in simple words every time you change the slot you have to reboot the phone and boot again to twrp..
i hope this will work for you..:good:
If you don't have stock flash file then try from step 2. see whether it will work or not otherwise follow from beginning.
facing the same issue
i tried the same and getting the same error. even the twrp3.2.3.0 never worked while tried to flash that one more than 20 times, after flashing 3.2.3.0 my phone either boots normally or it gets completely power off. and if i try to boot into recovery using volume keys and power key , it boots in stock recovery. please help
Mine its ok now... i don´t know whats happen but suddenly it flash withou any problem.
See if it helps...
Make sure you're running a proper working Recovery
Flashing instructions:
Dirty flash (assuming you have rom on slot A):
1. Download all required files and place them to internal memory (ROM, twrp installer, gapps, magisk, ..)
2. Boot twrp to slot B and flash ROM and twrp installer
3. Reboot twrp to slot A and flash gapps (optional magisk)
4. Now reboot to system
Clean flash (assuming you have rom on slot A):
1. Download all required files and place them to internal memory (ROM, twrp installer, gapps, magisk, ..)
2. Boot twrp to A slot and wipe everything except for internal
3. Reboot twrp to B slot and flash ROM and twrp installer
4. Reboot twrp to slot A and flash gapps (optional magisk)
5. Now reboot to system
If you are coming from stock:
1. Download latest TWRP installer and image
2. Open cmd and type fastboot boot twrp.img (change twrp to its actual name)
3. You should be on slot A in twrp, if not change it and reboot to bootloader and repeat step 2.
4. Format data
5. Now follow instruction for clean flash

I have this issue and none of the steps worked.
I got my device 2 days back and it was in Oreo. I tried to update to pie but the update keep failing. I unlocked the phone and flash latest official fastboot rom using mi_flash and installed magisk using this guide:
https://forum.xda-developers.com/mi-a2/how-to/unlock-bootloader-n-root-magisk-easy-t3856800
Everything went smooth.
Today I tried to go further and instal PE rom using this guide:
https://forum.xda-developers.com/mi-a2/how-to/guide-how-to-flash-custom-roms-stuff-t3876375
Everything goes smooth until I boot to TWRP and try to flash the rom. It gave the error posted by OP. I have tried the following things since:
1. Try another two roms, same issue
2. Flash stock Pie using mi_flash then temp boot to TWRP latest version from 'a' partition, wipe everything, then boot from 'b' partition, wipe everything, try to flash. Same issue.
3. Install TWRP (it installed without any issue), reboot to installed TWRP, flash rom, same issue.
4. Try to flash with 'a' as active. Same issue.
5. All other possible combos (i think) of the above. In all cases everything goes as expected until I try to flash the rom.
Currently I have flashed the factory image back. Any help will be greatly appreciated.
Okay. Am currently on MIUI 11.0.3 (the latest one available for RaphaelIN)
So, the problem am facing is that, when i flash a custom rom, my phone gets rebooted to recovery and sometimes to fastboot(this happens occasionally) and i just simply cant get the rom to load.
Sometimes my phone gets into a state which resembles hardbrick (none of the buttons work, even holding the power button for 10secs doesn't) and after sometimes, usually 15 to 20 mins it restarts itself. This has happened thrice till date and all while booting to system.
The Roms i have tried-
-Pixel experience (unofficial) (android Q)
- Lineage OS 17 (unofficial)
- Havoc OS (both official and unofficial) (both pie and Q versions)
-MIUI (European rom)
I have also tried flashing the chinese, indian and global vendor (all done separately) thinking it was a vendor issue, but it also doesn't work.
Recovery is TWRP latest version, have also used orange fox recovery
Bootloader unlocking was done through the official method and the official app.
Any solutions for this problem and has anyone faced these problems or is it only me?

Consider this an overkill solution that always works for me if I run into issues with other methods. It will wipe everything so backup your data and apps.
Download the latest fastboot Indian MIUI ROM (for anyone else reading this download the ROM that is the same region as your phone)
Fully extract the ROM and flash it - make sure, if you use the Mi Flash Tool, that you change the flash option to 'clean all'
Boot into MIUI once, you don't need to actually go through the set-up, just let it fully load.
Boot the phone into fastboot and install TWRP - I recommend the latest mauronofrio TWRP.
After installing TWRP boot immediately into TWRP.
Format the data partition - don't skip this step.
Wipe cache and dakvik - don't wipe anything else.
In TWRP goto the mount menu and unmount the data partition then mount it again - others would suggested rebooting back into TWRP, either way works, you just need to make sure the data partition is properly mounted after formatting it.
Install the ROM of your choice - either have the ROM on a USB OTG stick, or copy it onto the phone from a PC whilst still in TWRP.
If your ROM doesn't include Google apps and services and you want Google, then install GApps - at the time of writing this Android 10 GApps is still in beta and packages bigger than nano may cause issues, so stick with pico or nano, assuming your installing an Android 10 ROM.
Boot into the ROM.
If you want Magisk, once the ROM has loaded, boot back into TWRP and flash the latest Magisk installer - it is possible to flash Magisk without booting into the ROM first and you'll probably be OK, but occasionally it can cause problems, I can't remember the details, but for the sake of 30 seconds I now boot into the ROM before flashing, just to be on the safe side.
At the time of writing this people have recently reported issues flashing GApps immediately after flashing Havoc 3.0 and recommend booting Havoc before flashing GApps. Although others say they've not had any problems. So if you choose to install Havoc you 'might' have problems if you install GApps without booting into Havoc at least once first.
I've never had problems when following this method.
You didn't format data that's why your rom doesn't boot. Follow Robbos nice guide and you are good to go.:good:

I did format the data partition coz that's one thing I and my friends always do when flashing new rom. I don't exactly remember but i think, the pseudo hardbrick thingy started after i formatted the system, data, cache & internal storage.
I will follow Robbos guide adn keep you guys updated on what happened.

Format data = (you will need to type in "yes")
Note: Format data or wipe data isn't the same thing.

Consider this an overkill solution that always works for me if I run into issues with other methods. It will wipe everything so backup your data and apps.
Download the latest fastboot Indian MIUI ROM (for anyone else reading this download the ROM that is the same region as your phone)
Fully extract the ROM and flash it - make sure, if you use the Mi Flash Tool, that you change the flash option to 'clean all'
Boot into MIUI once, you don't need to actually go through the set-up, just let it fully load.
Boot the phone into fastboot and install TWRP - I recommend the latest mauronofrio TWRP.
After installing TWRP boot immediately into TWRP.
Format the data partition - don't skip this step.
Wipe cache and dakvik - don't wipe anything else.
In TWRP goto the mount menu and unmount the data partition then mount it again - others would suggested rebooting back into TWRP, either way works, you just need to make sure the data partition is properly mounted after formatting it.
Install the ROM of your choice - either have the ROM on a USB OTG stick, or copy it onto the phone from a PC whilst still in TWRP.
If your ROM doesn't include Google apps and services and you want Google, then install GApps - at the time of writing this Android 10 GApps is still in beta and packages bigger than nano may cause issues, so stick with pico or nano, assuming your installing an Android 10 ROM.
Boot into the ROM.
If you want Magisk, once the ROM has loaded, boot back into TWRP and flash the latest Magisk installer - it is possible to flash Magisk without booting into the ROM first and you'll probably be OK, but occasionally it can cause problems, I can't remember the details, but for the sake of 30 seconds I now boot into the ROM before flashing, just to be on the safe side.
At the time of writing this people have recently reported issues flashing GApps immediately after flashing Havoc 3.0 and recommend booting Havoc before flashing GApps. Although others say they've not had any problems. So if you choose to install Havoc you 'might' have problems if you install GApps without booting into Havoc at least once first.
I've never had problems when following this method.

Guys i need your help,, i flashed my phones custom Rom tecno 7cs using sp flashing tool.
That worked and it showed the tick icon on my pc.
The problem is that it does nothing to my phone because the software issues are still there
my phone keeps restarting itself almost all the time and sometimes won't even boot it takes longer to boot,,, apps keep on crushing and many more.AM tired am going to break it and throw it if i don't get solutions asap!
So the flashing process only wiped data on the phone nothing else whatsoever.
