[RECOVERY] [OFFICIAL] TWRP for Shield Android TV

[Neuken6969]

i dont think a method exists for the 2019 nstv (tube) since theres no way to plug in a usb to pc without hardware modifications..

@elliwigy amazing to see you all over xda. Thank you for the reply, much appreciated. Going to have to buy what I should have the first time.

hi, I rooted the NVS Pro 2019. I used image 8.2.2 and vbmeta_skip from 8.1.0.
Worked fine, Magsikhide showed up under settings and it passed the safetynet test.

However, I let it upgrade to 8.2.3 and now there is no more Magiskhide under settings and it's not passing the safetynet test.

What can I do? thank you!!

I'll try to make it more clear lol...

1) Reboot to bootloader to start fresh...
a) fastboot flash staging blob
b) fastboot flash boot boot.img
c) fastboot flash recovery recovery.img
d) fastboot flash system system.img
e) fastboot flash vendor vendor.img
f) fastboot flash dtb mdarcy.dtb.img
g) fastboot flash vbmeta vbmeta_skip.img
h) fastboot -w
i) fastboot reboot bootloader

2) Now we will boot to twrp and install magisk...
a) fastboot boot twrp.img
b) select mount and mount everything it lets you (usually data, system_root, vendor, cache)
c) adb remount all
d) adb shell
e) rm /system (removes symlinked folder)
f) mkdir /system
f) mount -o bind /system_root/system /system
g) exit
h) adb push magisk-debug.zip /data/media
i) In twrp press install and navigate to magisk zip and flash it
j) adb reboot bootloader
k) fastboot -w
l) fastboot reboot bootloader
m) fastboot flash dtb mdarcy.dtb.img
n) fastboot flash vbmeta vbmeta_skip.img
o) fastboot reboot

3) Device might reboot a few times but eventually loads.. when it does follow these steps
a) Enable usb debugging
b) make sure its authorized and connected
c) adb install -g magisk.apk
d) adb shell
e) su (grant root to shell when it pops up)
f) mount -o rw,remount /
g) Open magisk.apk on the device
h) When it pops up telling you it needs to install stuff select ok and install it.. device will reboot in 5 seconds...

4) When device tries to boot you should now be stuck at the android boot ani (NOT the nvidia logo).. then follow these steps..
a) adb shell
b) su
c) resetprop ro.boot.verifiedbootstate orange
d) after device boots run: resetprop ro.boot.verifiedbootstate green

After all this, you should be good to go finally lol.. it seems like a lot but its not really.. then eventually we will get proper stuff goin..

let me kno if these steps dont work.. b sure to follow to the T.. once to this point u only need to set bootstate to orange for it to boot all the way then u can set back to green.. i tried havin a script set to orange n works but so far havent found a way to set orange then after loads back to green automatically yet.. im sure theres a simple script with a pause or somethin that can be used tho

ok i have followed these steps but a few things are not happening quite the way you say they will:
1) adb install -g magisk.apk--- i get no directory found, so i have to take out the individual apk file out of the zip file and put it directly on my cmd folder, then it works, is this right?
2) after telling magisk to continue set up, you say it gets stuck on the android logo,,,,, mine didn't get stuck, it just loaded like normal.... why?

The thing is, adb shell, su seems to work, shell gets granted, so is this good enough am i rooted? whats a way to be sure that i am rooted once i am at the home screen?
Yes i am noob

ok just found out that some of this stuff doesn't seem to be needed
that resetprop stuff i didn't do at all, i downloaded droidmote(root acces required, opened it and pop asked to grant su and i did so i don't understand why because i'll restart shield, let it just boot, at homescreen, do adb shell, su.... thats it

I believe this is why

Magisk is dropping support for hiding root access from apps

Magisk, the popular Android rooting tool, will continue to be developed by topjohnwu, but without its root hiding feature called MagiskHide.

Question:
https://www.reddit.com/r/nvidiashield/comments/ptpd7n/install_twrp_by_modifying_the_developer/
Would it be possible to modify the nv-recovery-image-sheild-2019-atv-x.x.x.zip from the nvidia devs website to install TWRP on the Nvidia Shield 2019 (Tube) to get around not having a usb port for fastboot.

Also if it works control TWRP using remote that came with my samsung tv using CEC or plug in a keyboard/mouse to the tv.

Asked this question on reddit got no reply.

Has anything like this method been attempted?

I am trying to install the latest TWRP on my shield but I cant make it work. I can boot to it but when I install it with

fastboot flash recovery twrp-3.5.2_9-0-foster.img

it doesnt install. When I boot to recovery, i always shows the nvidia recovery

 

[Adromir]

Somehow I am not able to install TWRP on my Shield 2017 when I boot into it with

fastboot boot twrp-3.5.2_9-0-foster.img

it boots into it, but the screen flickers. When i try to flash it via

fastboot flash recovery twrp-3.5.2_9-0-foster.img

and reboot to recovery it always shows the nvidia recovery

The LineageOS Recovery seems to work though

this guide will work on nvidia shield tv pro 2017?
sorry for a newbie question but i cant find answer to my question, ty

What is wrong with twrp-3.6.0_9-0-foster.img ?
twrp-3.5.2_9-0-foster.img works fine, can access and format memory/data while twrp-3.6.0_9-0-foster.img have no access to it.

Hi,

I have mdarcy running 9.0.0 (android 11)

I debloated the rom and have set it up with no google account.
Twrp, Magisk, Afwall, MicroG, Adaway and Vpn fully working

I made a Twrp Backup as usual (with no error) but I can't have the shield booting after restoring it.
I have tried with several backups, I can restore them fine on 8.2.3 but on 9.0.0, the shield bootloop after the nvidia logo.

I also tried different ways of restoring : after just a factory reset, after a full wipe, after format data and even dirty restore without wiping anything.

I tried to fastboot flash mdarcy.dtb + vbmeta_skip after resrtoring but didn't help.

Does someone know what I should do to make my shield booting after restoring my Twrp backup ?
(I'm using twrp-3.6.0_9-0-mdarcy)

Many thanks for help

Edit : I figured out I have to restore everything but Sytem and System Image in Twrp, then reboot bootloader, fastboot flash system.img + mdarcydtb.img + vbmeta_skip.img then reboot
(just have to debloat/remove google crap once again)

twrp-3.5.2_9-0-foster.img works fine, can access and format memory/data while twrp-3.6.0_9-0-foster.img have no access to it.

The first 3.6.0 build had build system issues. Those have been resolved and foster has been re-built. Should be good now.

Thank you for sharing your experience, I have some questions:
- which vbmeta_skip.img file? as I know the v9.0.0 does not contains "vbmeta_skip.img" file, right? can you share file here please?
- how debloat/remove google on v9.0.0? can you explain detail more? can you skip google sign in? ( I tried by modifying build.prop but not success )
- how install Magisk? I install Magisk and device no boot! did you flash "vbmeta_skip.img" file?
- how install microg? I install microg magisk module on LineageOS 17 but I encountered black screen!
- also I install official microG release: https://download.lineage.microg.org/mdarcy/lineage-17.1-20220110-microG-mdarcy.zip but I encountered black screen too!

HI Guys , I would like to install twrp recovery, I have a 2017 Shield 16gb, with this boot loader currently,
What version twrp should I use: shield model P2897

 

[rchris494]

Reboot to twrp and adb sideload magisk.apk

HI Guys , I would like to install twrp recovery, I have a 2017 Shield 16gb, with this boot loader currently,
What version twrp should I use: shield model P2897

i use twrp-3.6.1_9-0-foster.img for experience 9.0. i don't install it. no real reason to. i just fastboot boot twrp-3.6.1_9-0-foster.img then do what i need to do. then reboot my nvidia 2017 16gb. if your looking to root. magisk 24.3.apk works just fine. i boot twrp set it to sideload then adb sideload magisk.zip i renamed the .apk to .zip but you don't really need to. i am using the developer image from nvidia. i use to install twrp on all my devices but you can do everything you need to do just by booting it. so i stopped trying to install it. then getting caught into a bootloop, no boot or twrp just wont stay as recovery.

Thanks guys, will give it a try

[jfromeo]

Any workaround for the 2019 non-pro (tube) version? I cannot fastboot without an usb port. Could a BT remote do the trick?
