If you're on stock recovery and wanting to convert to TWRP, then you would use the appropriate img file:

The Pie img is for flashing through adb in fastboot mode if you're on Android Pie

The Q img is for flashing through adb in fastboot mode if you'r on Android Q (10)

The zip installer can be flashed from within an existing TWRP installation or directly in Magisk.

Ahh I should have known that. I've been away for a minute.

I recently tried to update mine from a rooted 9 to the latest 10 update and bricked it. I used msm to get it back to stock and I've since updated with official OTAs. I plan on using this guide https://xdaforums.com/oneplus-6t/how-to/guide-oneplus-6t-unlock-bootloader-t3851789 to reroot it except I'd use the new ramdisk procedure to install TWRP. I'm really afraid to try and update my wife's from 9 to 10 so I wanted to just put it back stock and then reroot it like I'm doing mine. Hers is on 9.0.13 I believe, so if I wanted it back stock, could I just take the OTA and let it install and be done? Or are there other steps that need to be taken? I don't want to end up bricked again. Thanks!
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] jp0469:
It's been a while since I originally rooted my OP6t so I'm going to refrain from assisting you with your phone because I don't want to give bad advice. Now for your wife's phone, let's confirm a few things. There's no need to to go back to stock as long as you follow the correct process. Are you sure it's on version 9.0.13? That's not even the latest version of Pie. Is her phone rooted? TWRP recovery?
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] blockhead428:
It is rooted and on TWRP. I never updated it because I didn't get an official OTA notification until yesterday. I always wait to make sure I update with the right one. The procedure I saw was to take the OTA and let it install, before reboot flash TWRP thru magisk, then install magisk on the inactive slot. I did that with mine and it never booted up after install. I had to use the msm tool to recover it back to stock. I don't want to end up in the same boat with my wife's phone. I just want to get her on the latest version with no TWRP so that she can just take the OTAs when they drop. Hopefully all that makes sense.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] jp0469:
The update process you mentioned is exactly how I do it and I haven't had any issues. Other than making sure that you're using the right TWRP version and applying the full OTA, I don't know what else to suggest.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] sol212307:
did u do OTA or local upgrade?i always do local upgrade. oneplus has updated the latest link on their website(10.3.0) got mine from there although i got the OTA since i always mess up my phone with random stuff. do local upgrade always fix most of my problems.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Striatum_bdr:
Local upgrade means only that you are using a zip file stored on your phone. The way you get it (direct download on the website, download by Oxygen Updater or download with system update) has no impact.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] blockhead428:
I thought local upgrade meant use the system updater. If I was supposed to flash an update zip, then that's what it should have said.

So then can someone tell me if I can make a rooted 6t with TWRP back stock again by simply taking the latest OTA, letting it install, and rebooting? What will happen if I do that? I don't care about losing root or any of that. And by taking the latest OTA, I mean thru the system update, not flashing thru a recovery. I'm trying to get real specific help because I really don't want to brick my phone again or screw my wife's up.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Striatum_bdr:
Just flash the whole Rom zip (the one your grab in OnePlus website for example, place it at the root of your internal storage) through local upgrade. It will rewrite the boot partition and then restore stock recovery and kernel, without root

Anyone else have issues restoring from nandroid using 3.3.1-30? I did a nandroid backup last night and tried to restore. No errors when restoring but it must have borked my recovery because it goes to fastboot. Am I going to have to use MSM again to get everything back?
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] blockhead428:
And just to clarify, by local upgrade, you mean flash thru TWRP? Reboot into recovery and flash via twrp? Then reboot? Or can I take the update thru system update?

I appreciate everyone's help. I think my brick fiasco has turned me off flashing for awhile and I just want to get my wife's where she can take system updates without worrying about restoring TWRP and magisk and all that.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Striatum_bdr:
Man, local upgrade is the way OOS updates without twrp.... It's in Settings > System > System Update --> cogwheel in the upper right corner

Download the ROM file on OnePlus website downloads section, place it at the root of your personal storage (meaning it must not be in a folder...) then go in the cogwheel thing
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] blockhead428:
I got ya. I looked it up after I asked so I apologize for my naivete. Do I have to do it this way or can I let the system update download the file and install?

It's the same file do as your want

Boot into twrp. Flash the latest twrp installer from mauronofrio, 3.3.1-30. Reboot back to twrp to make sure it sticks. Flash magisk 20.1 then reboot to system. Should be good to go.

Tried that. You'll have wifi connectivity issues if you just flash twrp and magisk. In this case after booting to TWRP you'll have to flash ROM AGAIN and then twrp and root.

Good morning. I am asking help because I am not able to upgrade my OP6T (decrypted) Android 10 from Open Beta 2 to Open Beta 3 keeping TWRP and Magisk.

I tried to follow some methods here, but everytime I try to reboot into system, it keeps rebooting only into TWRP.

1) flash the full upgrade rom from official OTA - do not reboot

2) flash A/B retention script inside Magisk

3) install Magisk 20.2 on inactive slot (after OTA)

Reboot

Does not work, it reboots into recovery.

I tried also this method changing point 2:

1) flash the full upgrade rom from official OTA - do not reboot

2) flash TWRP Installer zip inside Magisk as a module

3) install Magisk 20.2 on inactive slot (after OTA)

Reboot

Does not work, it reboots into recovery.

Third method:

1) Boot into TWRP

2) flash the full upgrade rom from TWRP

3) flash TWRP Installer from TWRP

4) Flash Magisk 20.2 from TWRP

5) Reboot

Does not work, it reboots into recovery.

To boot into system, I need to change slot inside TWRP, then reboot. In this case I am booting into system, bnut it appears a message saying that the OS upgrade has failed and I need to retry.

Am i doing it wrong?

Thanks.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] TheBurgh:

So to root my fajita with OOS 10.0, I should:

- boot this twrp (https://androidfilehost.com/?fid=4349826312261677894) image with fastboot

- Install this zip (https://androidfilehost.com/?fid=4349826312261677893) to have twrp on recovery

To appropriately root your Fajita, properly fold the bottom end of the tortilla in so as not to spill the meat, vegetables and juices out. Then you will dig a 2 3/4 inch hole in your soil and plant your Fajita upright, it will need direct sunlight as well as partial shade for part of the day. This particular garden specimen may attract small rodents to coyote sized animals to mountain lions, we have heard of the occasional bear which could trample your other garden delicacies so take care to properly fortify your garden.

Sorry lol, I couldn't resist...but yeah you sound pretty on point with booting the Q twrp.img (which I believe the fastboot command has only recently been fixed in OOS 10.3.0) Then yeah install twrp.zip like you said and magisk afterwards. As far as wifi connectivity I've never really had problems there, but I've also been using Omega kernel for the greater duration of my stay on 10.3.

Sorry about the rushed sort of vague response, but I'm a little busy right now, I just didn't want to run off a junior member from the forums thinking I was just being an a$$ ?... Great sense of humor btw, goes a long way here.

I bricked my fajita :(

everything worked so smoothly until I got stupid enough to use a play store app to delete youtube, which was not yet implemented for the android q :( which caused my os to, instead of booting, getting stuck on the bootloader warning and then going to fastboot mode. I should just flash the OOS 10.0.3 zip back and everything would be okay right?

Should I do the same process of rooting again or will it be different?

And what's the correct way of removing a system app?

I guess restoring is like flashing an OTA update or a ROM, it's supposed to occur on the 'other' slot. Next time you'll update your ROM slot a will be used. No need to 'copy' or 'clone' to other slot.

[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Koushik87:
Just try to go into recovery and restart to the other slot(based on current active slot) . It would work if you your last installation ran smoothly. But chances are there you might downgrade to older os version.

Flashing os might remove ur root and magisk. First reboot to recovery and try the restoration of old backup if u have.

[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Timmmmaaahh!:
A little late on the subject but I'd like to add my €0.02.

The brilliance of the A/B slot system is simultaneously its flaw. Whenever something is flashed that touches the OS, the system may believe it has received an update and therefore has to switch to the inactive slot. You can easily mitigate this when you are flashing things in TWRP by checking the current slot in the Reboot menu before flashing. Then, when flashing is complete, you can confirm/change the slot by tapping either the 'Slot A' or 'Slot B' button before rebooting to system.

Of course, when we failed to do so or the system randomly decided to switch slots, our bootloader can come to the rescue with these life saving commands:

fastboot --set-active=a
or
fastboot --set-active=b

That is, by the way, one of the most important first steps in troubleshooting major issues with devices that sport the A/B system. It would be a shame to wipe things or start flashing OS files if you already have a perfectly working partition slot right there. It has saved me many hours and avoided a great deal of stress :)
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Arkmars20:
When you say the bootloader can come to the rescue with these commands, is that when your phone won't reboot system or keeps going back to bootloader?

Then do you open a command prompt to reboot current slot? I've been stuck in this situation to many times..
