How to install TWRP after Magisk?

How to install TWRP after Magisk?
I have a OnePlus 6 running Oxygen OS 9.0 and I managed to install Magisk by obtaining the stock boot image and using the magisk manager app to patch it to include magisk, then I flashed the patched boot.img using fastboot and ADB.
The reason I did it this way is that every time I tried to boot with twrp.img in order to flash twrp.zip, I would run into a screen saying Qualcomm CrashDump Mode and TWRP wouldn't boot.
Now I want to install TWRP and I was wondering if there is any way of doing it by using Magisk, so I wouldn't have to boot twrp.img.
Any help would be greatly appreciated.

Same problem here. Already tried to boot every version of TWRP without success.

If you have magisk manager with working root.... Then YES you can.... Just download Official TWRP app from GPlay... Open it give root permissions and follow the onscreen instructions.... Thats it...and yes use the zip not the img file

But there's no button to flash, I open the app, select flash recovery, select device, but theres no button to flash it.
See screenshot

do you have fastboot and adb installed on your computer? I assume so as you have oem unlocked to flash magisk, correct?
Copy the TWRP file that ends with .img to your desktop
if so, open a command prompt (windows key +R and type cmd press enter)
type "cd desktop" without quotes and press enter
type fastboot boot "twrp.img" (whatever the file name actually is)
Congrats, you are now in TWRP. But wait, there's more! if you reboot to system or other wise leave TWRP at this point you will revert back to stock. to flash recovery onto your device permanently, install the TWRP.ZIP (The ZIP is IMPORTANT) as it changes the boot on the OP6 to have the TWRP image (oh, by the way, there is no recovery partition on OP6 like previous devices [Thanks A/B partition!])
Now you can reboot to your hearts content. remember if you update OOS, you will lose the custom recovery, so flash the TWRP.zip after every update!

Yes I have fastboot and ADB on my computer (Linux btw), and as I mentioned it the first post, I already tried that, except that instead of booting into TWRP after "fastboot boot twrp.img" I got to a screen saying Qualcomm CrashDump mode (see attached image (the image might not be exactly the same as mine, I found that on the internet because I don't have my computer to reproduce it now)).

super odd. maybe your boot image is corrupt? still doesn't explain why fastboot boot isn't working though... Try bluSpark's TWRP image. it's a solid build and I am not having issues with it.
https://forum.xda-developers.com/oneplus-6/development/kernel-t3800965/page17
or you can also try swapping to the other partition by typing 'fastboot --set-active=_a' (or fastboot --set-active=_b) and booting to that recovery.
if that doesn't work for ya, try and restore stock via fastboot is my only suggestion:

I wonder if this problem has been solved? After having Root without TWRP since last year, I decided to flash TWRP now because I miss having a Nandroid backup. But just like op, right after I type in "fastboot boot TWRP.img", I end up with that Qualcomm crash dump error, resulting in a fastboot boot loop every time I restart the phone. My only recourse is to use the MSM flash tool that reflashes everything and returns the phone into factory stock. In the process wiping out all my data. I don't think there's anything corrupted
EDIT: the problem wasn't the procedure; it was the damned bootable TWRP .img files. I downloaded different TWRP.img versions, and they all failed to flash into temporary TWRP, except for this one that I found here: https://drive.google.com/open?id=1CJoBQ5ZuAExv27XLWwLMFYfHoLEu5YFJ You can use this bootable .img to flash any TWRP version compatible with your device

Does it work for Android 10?

Hello I'm having magisk root access and official TWRP app but can't use it for NAndroid backup, how can I use the app for backup and fishing custom ROM?

Pixel TWRP boot loop

So I did the following steps
- Unlocked bootloader
- Booted in TWRP
- Installed TWRP zip from the recovery
- Installed magisk.zip
Everything seemed to work fine, but now it takes forever to boot, an only boots into TWRP, asking for my password.
I cannot seem to boot normally.
Please help, thanks for your time

I think most of the time if you flash the boot.img from whatever stock firmware you are on it should boot right up,,,atleast thats what i did in the past

If you're running a stock ROM, you have to have the full factory image downloaded, and extract the boot.img file. Then, put your phone in bootloader mode and run the following command from your PC: fastboot flash boot boot.img
You will lose TWRP & root, but you will be able to boot. When you go through the process again, reboot after each flash, so you know whether it has worked.

Isnt that basically what I said? Just making sure because you included me on your post?

Your description sounds a bit suspicious, like you aren't doing the right method. Or maybe you are not just using the right (precise) terminology. There is a lot of confusion by folks on how to boot/install TWRP properly on this device, so that is why I am pointing this out, and hope you can clarify more specifically so we can then help you.
You don't need to adb push the TWRP.img file to boot TWRP, and you don't "install" TWRP.img using fastboot either. You should be trying to fastboot boot twrp.img, with that img file on your computer.
You do need the Magisk zip on the phone (and adb push is one way); as well as the TWRP installer zip if you intend to install (not just boot) TWRP to the phone. The TWRP installer zip not completely necessary, if you want to just flash Magisk and achieve root (not have TWRP installed on the phone).
Also, are any error messages showing up on your command prompt on the computer, and if so what does it day exactly?
Might be best if you cut/paste your fastboot commands, or post a screenshot of your PC, so we can see exactly what commands you used, error messages, etc.

ok let me try to be as specific as possible.
First i put the "twrp-3.3.1-4-guacamole.img" file in the adb folder and "twrp-3.3.1-4-guacamole.zip" in the internal storage of my phone
Then i switched off my phone, pressed vol up and vol down and power button to enter fastboot mode
i connected my phone to my pc
opened cmd window in the adb folder
typed "fastboot devices" to check if connected
then "fastboot boot twrp-3.3.1-4-guacamole.img"
on pressing enter , i get the 2 ok messages on cmd window and at that point my phones screen goes completely black with "Fastboot mode" written in the center
And stays there that way
now if i type "fastboot reboot" the phone reboots to the home screen
Hope i made it a bit clear
Sorry cant post screenshots at this moment, i am on vacation and dont have my laptop with me

You're using the wrong twrp image. You have to use the one for android q. Unofficial build of twrp for android q is available on the development section. Get that image, fastboot boot twrp.img and then install magisk 20. You don't need to install the twrp zip. You can just boot the image from fastboot whenever you need a custom recovery.
If you absolutely want the recovery, then you can flash it (remember to get the zip for android q) from magisk and then do direct install of magisk then reboot.

Good catch by the previous user, that you need to use an updated TWRP version.
Unofficial version -70 from the following thread is what you want (if you haven't found it already): https://forum.xda-developers.com/on...nt/recovery-unofficial-twrp-recovery-t3931322

Failed root, stuck on unlocked bootloader warning message.

Hi everyone,
I have tried to get root priviledges following a guide from Droidwin.com to flash Magisk throught TWRP. At the very last step, after flashing Magisk 19.3 throught TWRP when I tried to reboot my phone, it gets stuck on the "unlocked bootloader warning message", which is supposed to disappear after a few seconds and move on to the boot animation.
It seems like I can go to the stock recovery, which shows fastboot and wipe actions. At this point, I can acces the fastboot screen, but the device is not listed using the ADB command "adb devices", nothing is find.
I'm wondering, what can I try to restore the phone ? I thank you in advance for any suggestions.
Here are some additionnal informations:
---Device---
Oneplus nord running OxygenOS 10.5.5, european version.
---What I've done to get in this situation---
Unlock bootloader using ADB
Launch an TWRP image file using ADB
"Try" to root using Magisk 19.3 zip throught TWRP
Power off from recovery (using TWRP touch interface), but the guide tells to click reboot at this step ...
Get stuck on the warning message, not having any boot animation.

Try to boot in Fastboot.
Turn the Nord Off and start it with plus minus and Power.
Boot TWRP with "Fastboot boot "TWRP File name.img" and flash magisk 20.4

Thank you @denndenn.
I'm able to launch TWRP using the ADB command "fastboot boot [twrpfile].img". But when TWRP starts, it asks me for my decryption password, I type it, brief lines of code says "unable to read system/apex" before showing the home page of TWRP. Someone knows what this means, and if that can be the cause ?
I've then tried to reflash Magisk 19.3, which lead to the same result. I couldn't figure out how load Magisk 20.4 to my internal storage in order to flash it trought recovery ... Do you know how to flash a file which is not on my phone ?

Plug your phone to your PC while in TWRP, then you can use adb to push files to your phone, for example with adb push magisk.zip /sdcard. Then, flash Magisk in TWRP.

How about flashing stock boot to see if your OPN boots to system again and then simply load Magisk zip to your internal storage and then flash via TWRP?

Thank you a lot for your suggestions !
Here is the solution in my case :
Because fastboot was working, I was able to flash stock oxygen rom, and get every working, but it needs to erase all your data.
You can find a guide on the XDA topic "[ROM][STOCK][FASTBOOT][OPN] Stock Fastboot ROMs for OnePlus Nord". The rom list have the lastest roms version (09/2020), and the process is super automated.
Have a good week-end XDA !

Mine is stuck at the Razer Logo "Powered by Android" screen as well. When I first installed TWRP it worked okay and I could access the menus, but now I can only access the Fastbook menu and the device is no longer recognized on my computer.
In FastBoot it's showing the following options:
START
Restart bootloader (does nothing but restart to the Razer Logo screen)
Unlock bootloader [Unlocked]
Recovery mode (does nothing but restart to the Razer logo screen)
Wipe Userdata
Power Off
Secure boot shows "yes"
DEVICE STATE - unlocked
Any suggestions?
Thanks

Which file did you download? ZIP or IMG?
If you downloaded the ZIP and tried to flash that with Fastboot, then you screwed up. You may need to download and flash a boot image. You can find this on the Razer Developer Portal, just Google search Razer Phone Stock ROM. You should keep a copy of the latest firmware anyway just in case their site goes down. Extract the zip and you'll want to flash "boot.img" using fastboot flash boot (path to boot.img here). Flash it to both A and B slots, then try flashing the TWRP IMG again.
Note: If you want Magisk, flash the Magisk ZIP after you install TWRP. Then flash the TWRP ZIP to install the recovery. Flashing the TWRP will unroot your phone.
BUT... This TWRP build seem to have issues. It does not remember settings and it is unable to read the internal storage /sdcard folder.
I suggest using an older build.

Thanks for the info! The problem I'm running into now is that fastboot no longer recognizes a device is connected (although it shows in device manager). I would have to resolve that before I can flash a boot image right?

Try wiping user data and flashing the phone completely back to stock. That might be able to fix it, but if it doesn't you may have bricked your phone. If you did, someone else on here might be able to help you.

This build seems to have some issues.
1. Internal Storage shows up empty with 0mb.
2. It does not remember the user's settings. You can check the box for "Never show this again during boot" (for allowing changes) and it'll show up again during the next boot.

This issues will only show up when data can't decrypt.
So I guess you're using Razer official Android 9 ROM, but this build doesn't support Razer official ROM data decrypt yet.
It only support 3rd-party ROM data decrypt such as LineageOS, Pixel Experience, exTHmUI, etc.
