[Q] After rooted for a month suddenly unrooted

I rooted my Nexus 10 using the Google_Nexus_10_ToolKit_v1.3.0. When I did this I used SuperSU as my super user app.
After being successfully rooted for over a month my device is no longer rooted.
When I try to open SuperSU I get this message:
"There is no SU binary installed, and SuperSU cannot install it.
This is a problem!"
I no longer can run applications that require root access.
I tried installing Superuser and did the fix associated with that but it failed as well.
I haven't done anything to my device except for root it. Why would it all of a sudden become unrooted?
I still have the unlock icon on my boot screen.
Can anyone help?

Did you apply the 4.2.2 OTA update that came out recently? Updates will often unroot the device by removing suid from the su binary.
Easy enough to fix with an unlocked bootloader,new enough versions of Clockwork Mod recovery will check and fix it for you, or you can use adb with any of them to chmod u+s the su binary.
Edit: or use TWRP, was thinking of the Galaxy Nexus.

Yes. I think this problem happened right after the 4.2.2 OTA update.
I am not able to get into my recovery. When I try I just get a picture of a dead alien with a red triangle.
Do you happen to know the exact adb commands to perform this? I've tried search but I could not find anything.
Thank you for your help.

That's stock recovery. You need to use fastboot to re-flash just your recovery.
The adb command is something like "chmod u+s /system/bin/su", from the recovery (where you'll have a root shell in adb).
Or you could just install the superuser zip file from your recovery, once you've got the recovery running again.

I tried accessing fastboot but the Nexus Root Toolkit says I do not have a fastboot enabled device.
I tried running your command but nothing happened.
Do you have any other suggestions?

You could try installing the recovery through the Goomanager app. Once installed select menu and install recovery script.

this happened to me also.. but my nexus 10 is more than a month rooted.. from out of nowhere it suddenly becomes unrooted, caused by an unkown reason.. it didn't made any notification/alets or any dialog box when it suddenly becomes unrooted.. i noticed it when i used sb game hacker.. it says that the device is not rooted.. anyway i'll find a way to root it again this weekend..

TWRP - apps - adb sideload

Hello. I got SM-G935F with android 7.0 and I want to instal TWRP just to instal some aplications which has to be flashed. I dont want to root my phone. My question is if smth goes wrong while instaling TWRP via odin can It screw up imei and efs partition?
If I got stock firmware can I instal those aplications in zip with adb sideload using stock recovery and there adb sideload?

Yes you can mess things up using twrp and adb especially if you want
to keep your phone in it's original pristine 100% official stock condition.
As long as you are not trying to install applications which require root
you don't even need to use adb or twrp.
If you are talking about apk apps like the ones you find at the playstore
they don't require twrp or adb.
Sideloading any apk app is easily done simply by copying the apk app
into your internal or external sdcard and using a file manager install
them from there.
If you are talking about flashing or installing ZIP files they all would error
out for you because flashing or installing any zip files require root access.
Good luck,
Have a great day!

Fire HD 10 stuck on fire logo.

I rooted this device with offline rooting, removed amazon services which where marked safe to remove. installed xposed and flashfire but after certain point when I rebooted, OS Stuck on "optimizing system storage and applications". I tried do adb install stock fire os from recovery but nothing changed. I have adb access but no root right now. Initial OS version was 5.6.2. Now I am trying to install 5.6.3. May be that's the problem? Any ideas what to do? Thanks in advance
Edit: I have a root now with offline rooting method

try booting into recovery and sideloading the firmware.
Heres the link: https://www.amazon.com/gp/help/customer/display.html?nodeId=202194760
ps you will lose root access

How to remove magisk modules with stock recovery?

Good evening all does anyone know the best way to remove magisk modules that might cause a bootloop on android 10? I had used twrp when on pie and ran the module remover zip file but with a stock recovery how would this be possible? Many thanks.

How do I get to otg storage from TWRP? Does that mean i need to flash uninstaller from my computer, while connected with a cable ?

Latest twrp(-28) working properly
So if you are in bootloop , boot to twrp and flash magisk uninstaller or use the mm for recovery mode module

twrp-3.3.1-2-enchilada.img is latest for my phone, same issue.

Did you try this command with a computer and after opening an adb shell session:
magisk --remove-modules

so i go to adb shell sesshion, connect my phone which is in fastboot and type in "magisk --remove-modules"? i get an error "magisk : The term 'magisk' is not recognized as the name of a cmdlet, function, script file, or operable program.
Check the spelling of the name, or if a path was included, verify that the path is correct and try again.

You have to update your twrp to 3.3.1- 14(latest)

Sorry I have just seen you replied to my question. At some point after asking mauronoforio released a version of twrp that fixed decryption issues so I decided to stick with that as it was what I already knew

If you can enter adb shell with root ,then you can try to enter the command :
ls -l /data/adb
If you get the result correctly , there should be a module folder there.
try
rm -f -r /data/adb/modules
then reboot.
For my case, I tried to flash the prepatched boot.img but forgot to remove magisk modules.
Then stucked in the boot interface.
But infact the stucked phone had adb shell and root permission.
Then I removed /data/adb/modules and reboot, It worked.

is there any root method for Shield TV 2017 firmware 8.2.0

As title, do we have any way to root it with magisk yet?

I'm wondering myself. I tried to root with "magisk_shieldtvpie_r2.zip and although it seemed to have installed, after restarting I still didn't have root

I know you said you wanted magisk but have you tried the Nvidia Sheild developer only OS images?
Those come with included root.
https://developer.nvidia.com/shield-developer-os-images
My problem is I don't know if I can update my developer only OS image 8.1 to 8.2 without losing all my apps. I left the bootloader unlocked. Wondering why I couldn't simply flash developer os 8.2 over 8.1 if bootloader is unlocked?

i just fastboot boot twrp then flashed latest magisk on my 2019 pro 8.2.0

Maybe I'm doing it wrong, haven't flashed anything in a while and the place I use to get step by step guides from (nvidiashieldzone) shut down. Mind telling me the steps that you used to root?

I successfully root on normal firmware 8.2.0 with the lastest magisk. I dont know about the developer firmware.
1. I disable all magisk modules and restart
2. Boot to fastboot mode
3. Download and extract the firmware .
4. Run flash all.bat to flash the 8.2.0 firmware
5. Reboot after complete(let the shield completely boot up)
6. Use magisk manager which previously installed to patch the boot.img
7. Reboot shield to fastboot mode and flash the patched boot.img
8. Rebbot
9. Now i enable modules.

question to you guys who have rooted.
Did you get AFwall+ to work?
I have both 2017 Pro model shield and 2019 Pro model. I would like to root so I can uninstall all the crap, and then install AFwall+ firewall and just enable outgoing twitch, spotify, youtube, and some small services I use..

I had developer image 8.2.0 installed on the Nvidia 2017 16gb, updated via Ota to latest 8.2.2 but lose root, how do I root again? Thanks

Has anyone found a way to root 8.2.2 yet?

I just got Shield the other day and it came with 8.2. Would flashing with rooted firmware wipe it clean? Same for just rooting it?
