Flashing stock recovery and taking Android 10 OTA (without data loss) - OnePlus 5T Questions & Answers

Hi guys!
I am running oxygen os 9 on my oneplus 5t. I have TWRP and Magisk installed. I would like to unroot my phone, return back to stock recovery and then take the android 10 ota. I would like to achieve this without any sort of data loss.
My plan is the following:
-Unroot my device using 'complete uninstall' in magisk
-Flash the stock recovery image using adb/fastboot
-Take the OTA
It's been a while since I tinkered around with my phone, so I am a bit confused. Do you think this will work? Will I lose any data?
Thank you for the help in advance.

Why do you want to OTA? You can follow the guide in the official thread here for a rooted device. From memory, the dirty flash also restores the stock recovery.

Best way to upgrade to O from current state? Stock 7.1.1 rooted.

So I have a Play Store Pixel XL running stock 7.1.1, rooted, with TWRP 3.0.2-0-RC1 recovery.
Most upgrade guides I've read seem to assume stock recovery, or no root to start, or some such.
What do I need to do to get to Stock Android O, rooted? If I need to wipe the phone I can, but I'd prefer not to if I can avoid it.
Thanks!
If you don't want to wipe just update through factory image, just open the factory zip, open flash-all file and remove "-w" from last line, then execute it (update without wipe)
But I suggest to flash the stock factory image with the "-w" to make a clean install, flashing major release like 7.x -> 8.x is always better wipe to avoid potential issues.
But yes, you can first give a try without wipe and only if you find bugs try wiping. Your choice.
simply flash the OTA, then re-root

Use full unroot in supersu. Then take ota. Then root again after upgrading to O
Thanks for the help everyone, you pointed be in the right direction.
In the event that it might help someone else, here's what I ended up doing:
1. I downloaded the OTA, booted into the TWRP I had currently installed, and then sideloaded the OTA.
2. I used ADB to push the newest TWRP flashable zip, the latest SuperSU, and the latest SU-Hide to /sdcard on the device.
3. I then used the most recent TWRP bootable img, booted into it with fastboot, and used it to flash the TWRP zip I had previously pushed to the phone storage. I then had the OTA with the latest TWRP installed on the phone.
4. Finally, I rebooted to recovery on the phone (latest TWRP now instead of stock), and flashed SuperSU and SU-Hide.
I'm now stock, rooted, on O. No wipe necessary, kept all my apps and data. So far the OS itself has been entirely stable. I had an issue or two with a few apps after the upgrade, but those were fixed with a quick re-install. Except for Better Terminal Emulator Pro, seems it doesn't want to work on Oreo and it's no longer under active development. It's fine though, there's other terminal emulators out there.
Thanks again for the help!

Which version of TWRP do you have TWRP working with Oreo 8.0?
I can boot into the modded TWRP 3.1 (fastboot boot twrp-3-1-pixel-bootable-mod.img) but AFAIK there is no working flashable recovery for 8.0 yet.
quick question, are the steps the same for stock root 7.1.2? I've never installed twrp. I've fastbooted to it to root and that's it. I'm familiar with that as I've sideloaded all the ota security updates and the re-rooted.
my main question is su-hide required? I have never done it and have no reason to that I'm aware of. Seems all the guides I see involve su-hide and flashing kernels etc. I've never changed kernels since having the pixel. Really just want root for adaway.
I plan to do a clean install of O and then hope to root with fastboot twrp to flash supersu.

That's how I did it. I don't use suhide.
Does the -w in the .bat file format or wipe the data? I want a clean clean , o-fresh in the morning feeling kind of wipe

Thanks! What I ended up doing:
Decided to try and unroot and take the ota. super-su full unroot would not work. so I fastbooted to the mod twrp and flashed UPDATE-unSU. I then took the ota. then fastbooted to mod twrp and flashed super-su. worked perfect!

Seeking a better understanding

Hey all,
I'm trying to better understand what I'm doing with my phone here. Currently I have my OP3 rooted (aka unlocked bootloader, correct?) and on 8.0.0.
1. If I wanted to keep it rooted and reinstall the OS, is this as simple as downloading whichever ROM I want, copying it to my phone's internal storage, and flashing it in recovery using TWRP?
2. Is stock recovery (recovery_OP3.img on the oneplus.net website) the same part of the software as TWRP? As in the stock recovery is locked bootloader and TWRP is unlocked bootloader?
3. I've been searching for the most recent root guide, can I get a recommendation? I've read that SuperSU is not the thing to use any longer, but rather Magisk. Correct?
4. What is boot.img?
Thanks all

1. If you switch roms, always do a clean install (wipe all partitions) . If you want to get rid off all the mods wipe system and flash the same rom + gapps + root. You won't loose data since you are only modifying the system partition.
2. Stock recovery by Oneplus is as if says stock, you littery can't do anything with it apart from upgrading your OOS, wiping cache partitions and doing a factory reset. I do recommend the TWRP provided by Bluspark since that seems to be the only one I tried without any issues whatsoever.
3. Magisk is the new root method in my opinion, it supports Magisk modules which simply are mods that can be installed and removed with a single click (reboot required tho). You can compare it to xposed but very limited when compared.
4. Boot.img is your kernel, never flash standalone img files apart from TWRP since the kernel modifies more the only the boot img. Always flash the full zip.

How to upgrade O+5T to OxygenOS 5.1.0 when rooted with stock recovery?

Greetings. I received the OTA update (which I did not install!) on my OnePlus 5T today. I'm on OxygenOS 5.0.4 with magisk installed, phone is rooted, bootloader unlocked, stock recovery (no TWRP).
What's the right path to upgrade to 5.1.0?
I'm experienced with the command line and have no problems with it.
Based on my ideas, I think the path should be:
- Download full Oxygen OS 5.1.0 Full Zip
- Start TWRP using adb
Code:
fastboot boot
(which TWRP version?)
- Wipe dalvik and cache
- Flash the downloaded file
- Wipe dalvik and cache
- Flash magisk
That's it. Am I missing something? Do I need to reinstall magisk as specified as last step? Which TWRP version should I use (from the official website?)?
Thanks for your help :good:
Please go through the dedicated update thread that ive made for the update
https://forum.xda-developers.com/oneplus-5t/how-to/official-oxygenos-4-7-2-7-1-1-ota-t3709265
The thread has all the instructions and files needed to update. As far as twrp is concerned i recommend latest codeworkx or or bluspark recovery. The links are available on the thread.
Feel free to post on the thread if you have any further doubts.
Thanks @Funk Wizard , I read that thread (I linked it in my post) but it mentions "For Stock Non Rooted Users with Stock Recovery" and "For Rooted Users with TWRP Recovery" while in my case I'm rooted with STOCK recovery, which doesn't fit any of those 2 sentences. Which one should I follow?
As you are rooted you can flash the full zip from stock recovery that would remove root or you need follow and flash via twrp. If rooted stock recovery is no good TBH and i recommend staying on TWRP.
You can flash twrp from fastboot and then follow the instructions on the flashing post.
In case you dont need root anymore you can just flash the full zip from stock recovery. It will remove root and you will stay on stock recovery. In both the cases, use the full zip to flash via twrp or stock recovery.
No good? Please be more specific, why it's no good? From my understanding keeping stock recovery with magisk installed and bootloader unlocked allows me to pass all SafetyNet checks, which is very helpful if you don't want to deal with apps complaining that you are rooted. I can easily boot to TWRP as long as I can plug my phone into my computer by just using the fastboot command. The only downside I could see is if I brick my phone and have usb debugging disabled, I can't fastboot from adb.
Flashing TWRP would make me fail SafetyNet checks, which I'm not interested into.
After I flash the full zip, do I also need to flash the OTA update?
Thanks by the way, basically the only real "special" thing I need to do is install Magisk again after flashing.
Flashing twrp doesn't break safety net. So it's upto you if you want to stay on stock recovery with no additional benefits or on twrp.
Also, if have full time zip then you don't need to flash ota zip again.
That's good! I'll definitely flash twrp in that case.
@sshivampp Sorry to resurrect this thread, but looks like it's important. On TWRP website itself it's stated that installing TWRP would break dm-verity. What's the consequence of this? https://twrp.me/oneplus/oneplus5t.html

Downgrade from Android 10 (OB2) to Android 9.

Hi guys I wanna ask you if someone tried to downgrade from android 10 to 9, I really didn't like the gestures and other things in new android.
Right now in don't even have TWRP installed.
It's possible to just download the official rom and flash it with the normal procedure :
I mean :
Local upgrade and upgrade with the file?
I'm really retired about flashing customs roms, that's why I even don't have TWRP installed.
As far as I'm aware your only options are:
1. Use the unbrick tool for the 9.0 software (wipes everything) https://forum.xda-developers.com/oneplus-5t/how-to/op5t-collection-unbrick-tools-t3898890
2.find a rollback firmware on oneplus site (will wipe everything but can do through local upgrade option) https://androidfilehost.com/?fid=6006931924117903378
3. Flash twrp (rather easy through fastboot) wipe system,data,cache but not vendor then install the desired oos software. (Will retain all the files on ur internal like downloads, images, folders etc and once the software has installed it replaces twrp back with stock recovery)
Twrp

https://www.oneplus.com/uk/support/softwareupgrade/details?code=PM1574156155944
Personally the 3rd is the easiest and only choice for keeping files.
But if you don't mind losing everything then the second is the same as how you updated to the beta from what I can gather. if you want everything to be 100% like day one then the unbrick tool will flash everything including firmware, radios and so on but has to be installed on a Windows computer and then plugged in to phone
Have you had any luck downgrading? I am also not liking 10.
If you have twrp back up you can revert back without losing data.
Instal via adb twrp recovery again, copy oos 9.0.11 to root then dirty flash it , flash magisk if you dont want to lose twrp, then restore only data from backup. Remove pin before start anything.
AFAIK, you can't downgrade with stock OOS recovery
I'm now on 9.0.11 from OB3
Backup your data/apps, remove your fingerprint or PIN, flash TWRP, then install 9.0.11

TWRP Pixel 2XL? Please explain :)

Hey everyone! I'm sort of new to the whole custom recovery thing and while I know that there is a whole post concerning TWRP and Pixel 2XL, I would love if someone could take the time to explain, and maybe help me get it working on my phone.
BTW the reason I want to get a custom recovery is so I can flash a custom rom as Pixel OS just isn't cutting it for me anymore.
Here's what I know:
I am currently on an unlocked phone that is rooted on android 10. I heard that android 10 totally screwed up TWRP and makes it impossible to install after updating. Is that true? If so, is it possible for me to factory reset my phone to android 9 and then install TWRP after the fact? Or, have I totally screwed myself by updating to android 10? I know that I could just ask these questions on the other thread but it confuses me a lot and it would help if I could just get some clear answers.
TWRP works fine on Android 10. I would update to the latest update of Android(which is the August update for right now). Then copy any files( TWRP.zip and what ever Rom.zip) to your phone. Boot into bootloader and run the fastboot commands to boot into TWRP. Wipe data on your phone within TWRP and then proceed to flash the rim followed by TWRP.
Make sure you add the installer zip to the flashing queue when flashing a ROM or you'll get stock recovery again.
