How to Root and install Magisk on NSTV 2019 Pro v8.2.0

[LazorBlind]

After some testing it seems to me that, at least when updating from magisk rooted 8.2.1 with various modules installed, following any part of this guide will cause different forms of bootloop.

First I tried following the entire guide, and I get hung up on the spinning colored circles forever.

Then I though that perhaps since the dtb and vmbeta files are from 8.2.0 and 8.1.0 that maybe that was causing the issue. So I restored my backup and started over. This time I only tried to flash magisk. Upon restarting I found I couldn't get past the nvidia logo, and it would just keep restarting.

I thought okay maybe it has something to do with my magisk modules. So I used the Magisk Manager for Recovery Mode zip to put Magisk in core only mode, which will not load any modules on start up, same issue.

This is only my result though. Maybe I did something wrong. Honestly I would suggest anyone that is on 8.2.2 and has never rooted before to give it a shot. Just make sure you make a backup in TWRP before you do anything.

If I am reading this correct, you are saying you updated from 8.2.1 that was already rooted via Magisk, up to 8.2.2 with the Magisk intact?

IIRC, you should uninstall Magisk before updating a ROM. Did you try fully uninstalling Magisk and booting into 8.2.2? If that works, then if you install the same Magisk that worked on 8.2.1 and it does not work in the same way that it once worked, then it may be that we need a newer/hacked Magisk to make it work with 8.2.2.

Also, we may want to downgrade to 8.2.1 until someone figures this out. Did you use the main guide in this thread for 8.2.1 and that works fine? If so, I'll try that later.

Yes the guide works just fine on 8.2.1. That was what I was on when. I first rooted with this guide.

I didn't uninstall magisk before updating. I didn't even know about the recommendation to remove it before updating a ROM. When I updated and rebooted the shield, I checked Magisk Manager and Magisk just wasn't there. I used tried both the zip included here, and the latest zip and got the same results both times.

Oddly enough though, even though I restored my backup, the about page in settings still report as being 8.2.2, yet manually checking for an update asks me to update to it.

EDIT: meant to say the guide works fine on 8.2.1. Corrected above

I can confirm that the steps @mrhamed laid out in the first post work on 8.2.2. However, if you enable MagiskHide and reboot, the device will boot loop at the spinning circles.
If you disable MagiskHide before rebooting, you can avoid the boot loop.
If you get stuck in a boot loop, you will need to enter fastboot and flash the Magisk uninstaller.
If someone knows a way to flash a MagiskHide uninstaller, that would be great.
I'm curious what part of MagiskHide is causing it to boot loop though.

I think I have done it with quite an effort. Here are some notes:

• Driver issues persisted through the whole process. After many of the steps I had to reinstall them to get connectivity. In the end I found that selecting "MTB USB Device" and just hitting "Next" did it.
• Without a Shield Controller it is much harder to use bootloader. With power off, hold A and B on a plugged in keyboard while powering up and it will enable the keyboard and boot bootloader.
• I got bootloops frequently after unlocking bootloader. Had to try several times pressing "A" to stop the bootloop.
• The steps didnt say to install Magisk Manager so I didnt. I also did not do a factory reset after the initial bootloader unlock factory reset. It appears to be ok without it. Any thoughts on that?
• Forgot to make a backup before starting the whole thing so dont forget to do that! I have made one now.

Hope to see some ROMs soon. Thanks for the help all!

What are the advantages of rooting the shield pro? I've been looking in the other forums but not seeing things that are must have

I did some test and with Magisk beta Ai-upscaling work with Magisk hide (what i quick testing), but still cant reboot.
Have to test hide some system apps or hide Magisk manager itself, it maybe work reboot tho.

But its not big thing disable Magisk hide before rebooting, because rarely need reboot.
Noticing that too. I revert stock backup, flash only Magisk.zip axidentaly (not vbmeta etc..) but it boot fine.

I testing more this weekend.

Wait but don't you have to restart for magiskhide to take effect?

No, works after enabling it.

 

[LazorBlind]

No, works after enabling it.

Did you check to see if it passes safetynet? I have an app that isn't working properly and I think that's why.

Yes it pass.

 

[LazorBlind]

Yes it pass.

Welp. Guess it's about time to install magisk beta. I've been running stable and it didn't pass safety net when I tried.

Did you flash Magisk Manager? The instructions make no mention of it.

 

[KokkoM]

magisk.zip install it. I updated canary channel too, but reboot problem still here.
But upscaling, dolby, root etc.. working fantastic.

 

[KokkoM]

But you dont need flash at all. Go Magisk manager setting and change beta channel update via manager, install page press next dont X on recovery mode, then it open Method and update direct install. Remember swith off magisk hide.

Thats just it, No Magisk Manager appears. I unlocked, used TWRP to flash Magisk.zip but maybe I flashed latest one instead of the one here. Maybe I flashed wrong Magisk? Update: I flashed 21.4 instead of the 21.2 that was instructed. Does that matter?

Its not big problem. You can download magisk apk and install it just like anyelse apk.

Magisk manager doesn't show in the default app drawer. You will need to use an alternative launcher or go into the settings menu and click apps to view every app installed

Is it possible to flash beta over stable from magisk manager? In changed the update channel then tried a direct install but I think it just reflashed the same stable
