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

[Muscledup]

Installing the empty vbmeta_skipped is needed to prevent boot loops when installing Magisk. The rooted dev image does not use Magisk, so it is not necessary to use vbmeta_skipped. I don't understand what you mean by "add su binaries". If you didn't already have the su binaries, you would not be able to su from the adb shell. Your other post shows you have su.

Yeah idk that's what someone told me on here. How would I grant/use an app that needs root access? Ex if I open an app that needs root it will say I'm not rooted, so pretty much even with this systemless root it doesn't give me full read and write permissions

I've never tried the dev rooted image, but I don't think it will grant root to apps. The only root access is via adb shell, AFAIK.

You'll need Magisk to grant root to apps, and you will probably have to flash the normal nvidia recovery image to remove the current root before installing Magisk. You can't/shouldn't have two root methods. See this post in the Magisk support thread. https://forum.xda-developers.com/t/magisk-general-support-discussion.3432382/post-85290505

No one has reported successfully installing Magisk on 8.2.3 in this thread, so if you succeed, please report back. I know it works fine on 8.2.2.

I doubt I will try so I don't get yelled at by my wife lol but I have found some build.prop tweaks that might interest you all..

In a adb shell all I had to do is su root to get permission to change these.

I can't stand the horrible audio quality from the shield, it down mixes everything, and I'm hard of hearing and have to turn subtitles on to understand the words. This helps and makes a big difference in sound quality. You might have to adjust the sound delay settings but worth it imo.

setprop af.fast_downmix 0
setprop af.resampler.quality 255

These two I've been playing with, will report back
setprop audio.hw.passthrough true
setprop audio.is_dolby_formats 1

This command regulates the max frame limit or refreshrate_ui of the AI rendering, I increased it to 121 from 61 and noticed a big difference in motion and quality

Setprop persist.vendor.tegra.deepisp.fps_max 121


I've tried changing the refresh rate but it hasn't worked, thinking I might have to change the hdmi active value but idk

I am about to backup my device and push in the 8.2.2 update. I may lose root and if I do, I will try the guide and see what happens

I have booted a magisk patched image in 8.2.3 developer image and it works, just haven't flashed it..
I can use a Tegra overclocking app and overclock the cpu, gpu, and ecu successfully.. Everything works root wise but I haven't had the balls to flash it. If the shield turns off you have to reboot the patched image through fastboot to have root capabilities

If you run into any problems let me know, mine is working flawlessly with a fastboot booted magisk image, root and all. It's alot faster overclocked. With a few tweaks it makes it alot better. Really need to figure out the hdmi possibilities though for audio and overclock refresh rate

Hey mate,

Where you able to get AI upscaling working right ? I'm sure it can shows up as "enabled" but try some APP that actually enables it and see if it works

I would love to root my shield tv, just not 100% sure which I have. It's the tube 8gb I think it's Marcy???

Run an "adb shell" command. The prompt will be the code name for the ROM. My 2019 Shield Pro is mdarcy.

Yeah even with an unlocked bootloader you can, enable wifi debug and you just have to add a build.prop setting and change the filter to auto
[persist.vendor.tegra.hwc.upscale.filter]: [auto]
[persist.vendor.tegra.hwc.upscale.gfn]: [1]

Pretty easy just make sure it's on ai enhanced,
adb shell getprop

Add
setprop persist.vendor.tegra.hwc.upscale.gfn 1

On the filter you can leave it or change it to auto I think, mine had a different filter on it but I set it to auto

I entered adb she'll and got sif:/ $ ... Not sure what to do now

According to this thread, that model of the Shield is not rootable. https://forum.xda-developers.com/t/2020-shield-tv-streaming-stick-root-possible.4194825/

This thread is for the mdarcy model, so it is not applicable to the sif model. If you want to search further, google "nvidia shield code name sif".

ty bud, but somehow i am still unable to get it saying "enabled" with bootloader on.

and it doesn't seem like it's doing anything, did you actually had it working?

This work for 8.2.3? Or is there a way to downgrade to 8.2.0?

I never test this method on 8.2.3, but as my experience it would works if you through the steps carefully.
