Q ~ Installing TWRP after root and magisk.? - OnePlus 6T Questions & Answers

I rooted my Op6t with a one press kinda deal here. It didn't include TWRP. Is there an easy way to just install TWRP? Though my biggest question is will this reset anything?
Thanks.

Confused New User

My device is due soon and been going through the forum preparing myself. I am a bit confused though and would appreciate some help.
1- TWRP
From my other devices N5, 5T etc flash TWRP and you're on your way.
With this device it's Fastboot boot into regular TWRP wipe, then into deadman's TWRP to install ROM. Other instructions mention going into partition A then to B. Is permanent TWRP install not suitable for this device?
2-Root & Magsik
It seems that everything on this device is dependent on using Magsik for one thing or the other. I prefer to use SU as it always works with my setup. I'm not interested in safetynet. Do i really need to use Magsik?
After ROM install I use Xposed, SU, Xprivacy Lua, Titanium pro, Tasker.
Thanks.

As much as I'd like to help you, I don't get what you mean. Care you elaborate?
Sent from my Mi A1
I want to flash a permanent TWRP & flash ROMs etc like on a regular device.
Can this be done on this device?
Of course

I found this for you, hope it provides some info, also try forcing Google to give you results with kws like "SuperSU" and "su" by placing them inside quotes "" and by adding a + in front of a keyword.

1. You can Install TWRP permanently
As there is no separate recovery partition
fastboot flash recovery recoveryname.img command will fail
So you need to temporarily boot your phone to TWRP first n then make it permanent (Optional)
2. You can use SuperSu, technically there shouldn't be any problem as bothe Magisk and SuperSu patches Boot Image (haven't tested though)
Thank you for your replies.
Managed to install TWRP and decided to stick with stock for now, but install of Xposed fails. Now looking to solve that.
Bought this device because it was cheap. If Xposed install fails will return it.
I have made a guide to simplify the installation procedure: https://forum.xda-developers.com/mi-a1/how-to/lineageos-gapps-magisk-twrp-dolbyatmos-t3762939/
If you want to stay on stock, you can skip the LineageOS related stuff.
Thread cleaned
Lets be honest, this is a development site, lets keep the racism out of here.

I know you don't want to install Magisk, but you can install Xposed with Magisk without any issues

Installed TWRP, no access to sdcard

I've got my hands on this phone today. So I went on and unlocked bootloader and installed TWRP (with all in one tool).
But now when I want to root my phone through twrp, i can't access my files. I see the root folders, but when I go to /sdcard there are only a bunch of folder with random letters.
I don't know what's wrong. It is not asking for a password or anything.
Twrp has decryption issues currently. It's mentioned in the thread.
No need to install it yet, just boot to it.
If you're wanting to install magisk, just go into adb sideload in twrp and sideload magisk from your PC.

Thank you for your quick reply!
Is it bad that it is already flashed permanent? Or do I need to flash original recovery again?
I'll try and sideload it. Haven't done that before.

The current TWRP has decryption issues as its based on the Oreo tree and encryption/decryption works differently on pie.
Here is a post i did so follow it for easy instructions.

I read in your post that you not recommend to flash twrp, but I already did. How do return to original recovery?

Nothing to worry about. You can dirty flash the latest full zip from my update thread or just wait for the next OTA as and when it comes flash the full zip that will overwrite the recovery partition to stock. For now TWRP is basically useless so i did not recommend to flash the installer instead just boot in it sideload magisk or kernel if you need to and retain stock recovery.
Feel free to ask anything if you are still in doubt :fingers-crossed:

Thanks for the info! I'll wait for an update.
When that update comes, can i just install it from the settings? Or would i have to manually download it and install it thru TWRP/sideload?
And i guess I lose root after i update so i would have to boot into twrp and install magisk again.

As and when the update comes, just let the system download and install the zip. It will auto download and install the full zip when it detects root/system modifications, just make sure you uninstall/deactivate all mods/magisk modules/ substratum overlays before you update. You can check for easy instruction on the third post of the update thread. I will update the thread as and when the OTA is released.
Also you guessed it right the update will unroot the device so you have to root it again so you can either do the same sideload way or just do it from the magisk manager - uninstall - install ota (do not reboot) - install magisk to second slot - reboot :good:
I will again update the detailed instructions for easy understanding and and when we have the update :good:
Just stay subscribed to the update thread :good:

What is update process for OP6T 9.0.16 > 10.3.3 rooted [Global]

I have OP6T OxygenOS 9.0.16 and I would like to update it to the latest 10.3.3 with root.
What should be my process of doing so? I have not been in touch with rooting for the past 3 years so I don't want to mess things up. Another note is that while I am on OxygenOS 9.0.16 I tried to root it which was failed, but now few banking and calling apps such as TextNow thinks that my phone is rooted and they can not run -- but my phone is not properly rooted according to root verification apps.
Please tell me how should I do the update to the latest version from this point and then I would like to unlock bootloader and install recovery and root it as well.
Please advice.
BTW my OP6T is global

Flash OOS full rom zip on both slots using TWRP also flash TWRP installer zip on both slots reboot recovery flash magisk reboot system. Easy peasy.
Example:
Boot recovery: fastboot boot twrp.img
flash OOS 10.3.3 full rom zip
flash TWRP installer zip, reboot recovery,
flash OOS 10.3.3 full rom zip, format data, wipe data,
flash TWRP installer zip
Reboot recovery, flash magisk,
reboot system.
Note: I use a USB stick. I flash magisk zip off my USB stick.
That's what I do when I use OOS on my 6t far as installation goes.

Are you sure there is no need to update to 9.0.17 and then 10.3.3?
I've asked once and someone said that 9.0.17 is neccessary before update to 10.3.x.
Also there is option to flash from system without losing magisk modules:
1. Flash manually from update center (do not reboot)
2. Enter magisk and flash to another slot (after OTA)
3. Flash TWRP installer like magisk module
4. Reboot
But I'm not sure if I remember it correctly.

10.3.3 is all that you need. 9.0.17 isn't the only way anymore.

I have a T-Mobile SIM unlock OnePlus 6t and I converted it to an international model so when my conversation was done I was on OOS 9.0.1.1 and I booted TWRP and installed 10.3.4 full rom on both slots and also recovery installer and all just like my previous posts stated and everything went fine. I used mauronofrio's TWRP the version just before the latest 3.4xx when I did this.
I always download quite a bit of various firmwares and also TWRP versions before I start flashing things just in case something goes wrong I already have other things maybe I can use and I don't have to stop and wait for some download to finish... And I'm quite sure you know this but definitely make a backup of everything beforehand to USB or transfer it to your pc just in case you end up needing it as a precaution.
Edit added:
I am assuming that you already unlocked your bootloader... I believe everyone knows to do that that's on XDA forums before you can do anything to any device .. I say this after reading post below me here. I guess I should have said that earlier but I just assume everyone knows that on the forums... My bad. ??
From fastboot on Linux PC:
sudo fastboot oem unlock (then hit enter on keyboard) use volume keys to move to unlock option and your Power button to select it and confirm. For more info see: https://www.xda-developers.com/oneplus-6t-unlock-bootloader-root/
Super easy to unlock bootloader just remember it does wipe your device clean so move anything to want to PC or USB stick first...
I would think you could just update oxygenOS to latest then re-root no? Assuming your already bootloader unlocked which it seems like would be the case if you have an obsolete magisk installation.
Edit: re-reading your post maybe it is not unlocked as you failed to root. In this case just unlock then flash the latest fastboot image and then magisk as others have already stepped you through. You will lose data when you unlock so backup first.
So if I'm on 9.0.16 I could flash latest OOS directly from TWRP and then flash magisk? And no data loss? Of course I'm rooted with bootloader unlocked.
Oh dear this process is getting harder because recently I was busy doing other things it sounds way harder it actually is. Isnt there a way I pay someone on this forum so that user help me do this. Like download stuff links and proper version and follow me up with it because i want to do this without messing things up!

It is indeed a tough job. This A/B partition has had a lot of people bootloop/soft bricked their phones.
However, you need not pay anybody anything. If you are on stock, I would've recommended you upgrading it via Oxygen updater (a 3rd party app on the play store) and then using the latest recoveries (TWRP 3.4) and flashing it via Fastboot mode.
It is super easy.

Android 10 and root?

I'm on Android 10. I unlocked the bootloader.. easy.. I downloaded the corresponding file for my device, software channel, version. Ran the boot img through magisk manager. So I have the patched boot img. Before I go further with trying to flash it through fastboot, I was wondering would this successfully root my device? I'm hesitant because I haven't came across anyone discussing there success in doing this with Android 10. I really don't want to proceed until I know I'm ok to go ahead. Thoughts?

Sorry to butt in but that did not work for me. Rooting with magisk removed my installed twrp. Could that be a bug in android 10 or latest magisk?
fastboot flash recovery twrp.img should permanently install twrp recovery into op7t and Magisk flash should not replace it. If you flash oos10 after that then stock recovery will replace twrp recovery

I was busy with other things and only just came back to this topic. I agree with you, HueyT, Magisk rooting
(which I do according to the Magisk directions which say to patch the boot.img and then flash it)
should not remove the permanent twrp installation on my phone. But it does
remove it on my phone! I've tried it repeatedly.
What I end up with is a rooted Moto G7 running android 10 and when I :
—power off completely
—volume down + power takes me to the stock recovery (not twrp)
—in that stock recovery if I go to the 'recovery' option I get the open android with red exclamation mark. Happens every time.
—long power hold then reboots phone to rooted android 10.
What I have not tried yet is to permanently install twrp again and then, in twrp install Magisk 23 zip. Maybe that will allow me to keep twrp installed.
Do you think so?
It is just frustrating because this is my main phone and I can't afford to mess it up.
Any other suggestions on how to keep twrp installed on the Magisk rooted phone greatly appreciated.
Thanks for replying.

Which I interpret as you agreeing I should try installing the Magisk zip from within twrp.
(That is not what the Magisk instructions say to do).
I will try that later today when I get a chance.
I have also not flashed copypartitions.zip. Should I?

That worked.
Rooting by installing Magisk.zip from within TWRP allowed me to both root and retain the TWRP installation.
Thank you HueyT.

It's been two years but I did try injecting Magisk from within TWRP. I've also downloaded "factory" images and rooted those, them installed them. If I remember right, I did the injection method with this G7. It's the best way IMHO because the installed image is tailored your your device.

You can say that again. I've had several system crashes with 10, something I've never had with pie. Even after clearing cache, updating all apps, etc. So has my wife on her own unrooted G7 which just accepted Moto's own ota update to 10.
I do have a TWRP nandroid backup that I did just before flashing 10 and I've often considered going back to pie. But I worry about 'something' else going wrong like it did when moving to 10. It's my main phone and I can't afford to go through all I went through moving to a rooted 10. Wish I hadn't bothered.

Install recovery and Root

I apologize if this is in the wrong area.
I did a search and came up empty.
Is it possible to unlock the bootloader, install twrp and magisk on OnePlus 6t 11.1.2.2?
I have been out of the rooting scene for a long time, since SuperSU was a staple and magisk was an infant.
https://forum.xda-developers.com/t/...-flash-twrp-root-nandroid-efs-backup.3851789/
Here's exactly what you needed.
