Short story: Using ODB: Unlock Bootloader, flash a custom recovery, flash latest fullOTA stock firmware, flash nomoreota.zip. Just to be sure the tablet does not download the killswitch while you do all these, disable all internet connection (WiFi and LTE if you have that model) until you have run nomoreota.zip. To check that TegraOTA is gone, in Settings -> About Tablet, the first option should not be anything related to updates ( "Check for update..." ). Once that is missing, you are safe to open internet and enjoy your stock firmware.

Remember only that you will not receive any updates anymore, not even new firmware. All have to be flashed manually though ADB and each time, after the update, to flash nomoreota.zip.

The page from Bogdacutu shows only the killswitch. You still have one update to do after the one that introduced the recall. I would suggest flashing it manually (update 3.0.1).
[Shield Tablet General] SnowiiSnowii:
thanks topcat36!

so due to not activating the new unit + not having the last latest update + no killswitch waiting (do I understand the Bogdacutu page correctly? It shows that the server will push the killswitch to you SN, correct?) for the old unit I am fine to do all steps as You've outlined and once I have nothing related to updates thanks to flashing nomoreota.zip, I am ok to fire up the new unit... correct?
[Shield Tablet General] topcat36:
If you want to keep your old tablet alive, is a must to do those steps, no matter what. Once the new unit connects to the OTA server, the killswitch will be sent. Your only chance is not to be received by the old tablet.

I removed the TegraOTA file on the new one also, before ever connecting it to Internet and after 23 days no killswitch is waiting for the old one.
[Shield Tablet General] punifra:
I confirm the fix works. My "kill switch" (urgent ST - YY OTA) has been triggered on my old NVIDIA Tablet, checked through Bogdacutu website but the same old Tablet is still working flawlessly, and all the Apps updated. :cowboy:
[Shield Tablet General] Skiller01:
I have custom rom in my tablet that was supposed to be deactivated but i want to go back to stock firmware but in order to do so, i need to flash factory image through fastboot which will wipe my main partition. My question was, would i be safe from bricking if i flash 3.0 factory image or anything below 3.0? I really need an answer asap
[Shield Tablet General] frenziedfemale:
You could flash the latest through tewrp or cwm but before you reboot...flash SuperSU and the nomoreOTA zip from the first post.
[Shield Tablet General] Skiller01:
I thought factory images can only be flashed through fastboot and not through custom recovery
[Shield Tablet General] frenziedfemale:
Ya sorry i believe you have to flash the full thing then TWRP or cwm then supersu then the nomoreOTA zip. The kill switch is a separate update. Others have updated to 3.1.1 without killing the tablet. I know this threadbis long but take some time to read it and you should be fine
[Shield Tablet General] JuStAdsor:
Just some notice!

Recently after playing around with custom ROM, multirom and other stuff like this I have decided to return to stock ROM.

In order to clean things a bit, I have decided to format: system, data, cache, and Dalvik.

After this I have flashed the full image zip.

Secondly nomoreOta.zip

Third supersu

On nomoreota I have noticed an error something that he was unable to mount a partition.

Rebooted and started the tablet normally.

Looking around I have noticed that the Tegra Ota was not deleted.

Lucky, my new tablet was not activated yet, therefore returned to twrp and flashed nomoreota again. This time it runner properly.

Now, if you are doing the same as me, make sure on the first boot you start your tablet with no sim and no network, than reboot and run the script again.

[Shield Tablet General] frenziedfemale:
You need to flash SuperSU first. You need root access to flash the nomoreOTA zip. That is why you had an error
[Shield Tablet General] topcat36:
There is no concept of root in recovery mode. Is like having Administrator access in BIOS on a PC.

SuperSU is optional if you want root access in Android and delete TegraOTA manually (nomoreota.zip does this for you without rooting).

You can flash any firmware and package you want on the old tablet, without killing it with the condition that you stay offline from internet. Once online, you must have nomoreota.zip flashed and checked TegraOTA to be missing.
[Shield Tablet General] JuStAdsor:
No!

It doesn't matter what you flash first. You don't need root.

The system partition seams that it was not mounted properly.

I repeat. I have deleted everything.

[Shield Tablet General] DreadApex:
I always have to restart TWRP when formatting the system partition... it doesn't remount properly afterwards.
[Shield Tablet General] JuStAdsor:
Probably this is the case.

However I have posted this information so everyone will know and avoid having their tablet killed by mistake.

Is this method of removing tegraota folder working for OTA 3.1.1. as well or it is better to stay with OTA 3.1?

I have my old shield tablet LTE with OTA 3.1 and I have got a replacement tablet today (Slovak Republic - Europe - the new tablet is still power down) so I have decided to root my old tablet and remove the tegraota folder to prevent the kill switch. I dont know if I should at first carry out the update OTA 3.1.1. on my old tablet before rooting it and removing tegraotafolder or it is safer do not update and stay with OTA 3.1 (NVIDIA could possibly add another form of killswitch in OTA 3.1.1. in order to adapt to deleting tegraotafolder by many cunning owners)
[Shield Tablet General] Skiller01:
So as long as I don't turn on Internet and flash the latest factory image ill be fine? Then I can flash nomoreOTA and turn my Internet on? Using the website in the OP's post I put my serial number and found that the kill switch is awaiting my tablet. I want to go back to stock but I'm a bit confused and don't wanna risk my tablet being bricked.
[Shield Tablet General] bung-koe:
ohmyg!! My bricked tablet is working again ohmyg! I cant believe it it is perfectly working again! Yay!

Btw what should i do now? Can u help how to get the kill switch? Please im not good in english so i might mess understanding how to get it xd
[Shield Tablet General] topcat36:
You lost me. So your dead tablet came back to life and now you want the kill switch to kill it again ?
[Shield Tablet General] bung-koe:
Sorry i mean how to get rid off the kill switch? xD im really thankful my tablet is working again its really mircale it was really dead wont open what i did was just keep on praying then suddenly it opened like nothing happened ohmyg hahaha

[Shield Tablet General] Hellren:
Ok, let me advise you then:

1)unlock bootloader

2)flash nomoreota.zip

3)if you wish, flash a SuperSU.zip to gain root.

Thats it. I wont write a tut on how to do it, in this thread it was discussed like thousand times.

[Shield Tablet General] bung-koe:
i already did delete the ota manually and also flashed the nomoreota but when i checked in the Shield Tablet OTA Check it still says Next OTA: ST - yy (urgent)

what does it mean? my tablet is still in danger?
[Shield Tablet General] Hellren:
If you deleted TegraOTA.apk, then you are safe.

[Shield Tablet General] bung-koe:
even if i turn on wifi they cant brick it again?
[Shield Tablet General] subsss:
It means that your tablet is offered to download an update. TegraOTA would download it ... if only there is TegraOTA ;)
[Shield Tablet General] bung-koe:
right now there is no tegraota in the system/app but i check it still says the urgent

why?
[Shield Tablet General] subsss:
I just explained you ... According to Nvidia's databases, you never downloaded the urgent update, that's why it's still showing.
[Shield Tablet General] Hellren:
No, because the app that downloads that update is deleted. But i doubt they bricked it. If they did, you would not be able to recover it. Probably battery was depleted or something like that.

I'm in the exact same boat here,

To update to 3.1.1 or not?

Does it matter either way?

I'd like the stage freight fix applied , so I WANT to update, but not if it will create uncertainty in regards to nomoreota working properly.

Been following this thread since it was posted, thank you tons for all the hard work\attention to detail in decompiling! Haven't seen OP post in a while though...
[Shield Tablet General] Frankenscript:
My new tablet with 3.1.1 had no trouble with removing tegraota.apk via nomoreota.zip as flashed by TWRP. I don't want nvidia or anyone to be able to shove OTA updates at me so I flashed my replacement with it. Removed the OTA check, no worries.
[Shield Tablet General] Konstrictus:
So far it seems to be safe to update to 3.1.1 (flashing NOMOREOTA again afterwards...).

There have been no posts saying that the tablet was bricked after the update...

:fingers-crossed:
[Shield Tablet General] Steelswarm:
So I've been following the post and reading almost everything I could from it and I've got some questions myself... So I've recieved my replacement tablet a week ago but its still in the box, haven't booted it or opened it yet.

I've wanted to unlock the bootloader and root the old tablet to mess around with it a bit before it got killed but this post caught my interest... So what if I "kill the kill switch" and then flash ubuntu like in Bogda's post http://xdaforums.com/shield-tablet/development/running-ubuntu-natively-shield-tablet-t2985238? It would save me from the kill switch right? (by flashing ubuntu would it become a dual boot device or ubuntu device? I still didn't understand that much)

Also what are your thoughts on the new tablet? Should i kill the switch too or is it safe for me to leave it untouched and just use it normally?
[Shield Tablet General] Frankenscript:
Old tablet: Wipe it, let it discharge, send it back to the collection place or turn in to recycling center. It's potentially dangerous.

New tablet: I recommend the nomoreota process to prevent Nvidia or anyone else pushing an update through without your permission.
[Shield Tablet General] narutoaustx:
Sorry, I am a Total Newby.

I am not able to find CWM or TWRP application for the nVidia Shield Tablet.

Hi everyone I just rooted my tablet and deleted TegraOTA.apk from /system/app/TegraOTA with ES file explorer!:)

So am I good to go and turn my new tablet on or is there something else I should do?

Thanks
[Shield Tablet General] P00r:
I assume you did this on the recalled tablet, you should probably do it on the new one as well to prevent the OTA files trigers

Optionally

* delete the recovery partition altogether

* block ota.nvidia.com from your router

* enter 0.0.0.0 ota.nvidia.com in the tablet host files
[Shield Tablet General] Toscar12:
Yeah I just did it on the recalled tablet not the new one. So your saying I should do the same thing on the new one to? Also those other things how do I do them should I just google them?

---------- Post added at 05:35 AM ---------- Previous post was at 05:00 AM ----------

Hi i was naughty and just turned on my new tablet i even let it connect to wifi and update but both are still working fine:laugh: So am i in the clear you think as long as i dont update my old one?
[Shield Tablet General] topcat36:
Yes, you are fine as long as you don't update the firmware.

However, by connecting the new tablet to internet, with TegraOTA running, you just released the killswitch for the old one. Following P00r advice (removing TegraOTA on the new one) that could have been avoided.
[Shield Tablet General] MagilsugaM:
So I got my old tablet still working even though I turned off wifi and I already run the newer one however the newer one is not up to date yet. Would that still send the killswitch? I can still delete the ota from the old one? The old one still working but I am scared of turning it off xD
[Shield Tablet General] Toscar12:
Oh OK so could have I still have updated them both in the future if I removed both tegraota files? And buy not updating firmware does that mean I can't update to android 6.0? Thanks

---------- Post added at 11:10 AM ---------- Previous post was at 11:00 AM ----------

I'm pretty sure you have delete the Ota file on the old one before you connect them both to the net.
[Shield Tablet General] topcat36:
Is possible to update to any version you want, by flashing the full OTA updates manually in recovery mode. Just keep the tablet disconnected from internet before removing TegraOTA.
[Shield Tablet General] Toscar12:
O OK sweet that's awesome!, thanks mate!
[Shield Tablet General] JuStAdsor:
OK.

So just for you to be aware.

After receiving my new tablet, the first boot was in bootloader mode.

Changed the firmware to ww, flashed twrp and deleted tegraota.

The old tabled was already with twrp and rooted.

Even if I never booted my new tablet with tegraota, after a few days (one week I think), my tablet is scheduled for Next OTA: ST - yy (urgent).

Therefore be careful!
[Shield Tablet General] topcat36:
That's interesting. So what did I do (or didn't do) that one month after receiving my tablet there is no kill switch for mine ?

Did you check on Bogdacutu page the serial from the new tablet ? Must be something that made them aware of your new tablet being active....
[Shield Tablet General] JuStAdsor:
The only thing used were the nvidia proprietary apps.

And, to tell you the truth I am not a noob at all on this.

---------- Post added at 11:33 PM ---------- Previous post was at 11:24 PM ----------

By the way... just before receiving my tablet I was playing a bit with the old one. This playing included the removal of tegraOTA also.

However, digging around I found another updater apk.

The apk is called: Nvidia Tegra Service Updater : NvCPLUpdater.apk

I haven't delete it :( and maybe I should have. :(

Another thing that I did was to repeatedly check Bogdan's page for OTA.

It is possible that they have other triger, there's a lot of check-in made by android, although the removal of tagraota seem to be the main protection to prevent an urgent OTA flash they may have defined other method to assign the update than just this application, they could even simply enable it once they have a delivery confirmation...

This is why I am blocking the ota.nvidia.com on my router, I have not yet powered or fixed the new tablet yet. The ota check still say no ota for my old tablet.

They could even make this flashing part of a new rom upgrade it would be sneaky but not totally impossible! Remember how Linus feel for them...

[Shield Tablet General] sacasoh:
Why can't we just block the ota.nvidia.com in the hosts file in system/etc? If I understand correctly, this would block the device from acessing the website from any router/LTE connection.
[Shield Tablet General] MagilsugaM:
So I know I screwed up but the tablet still working. If I don't delete the ota it could kill it yeah? I am going to install twrp and a custom rom anyway.
[Shield Tablet General] alexong:
I have tried entering my serial number in the "Shield Tablet OTA Check" page

and my next OTA is None

does that means my old tablet is safe from being deactivated remotely?
[Shield Tablet General] topcat36:
For now... If TegraOTA is running on your tablet, when you will see the killswitch there, will be too late.

[Shield Tablet General] P00r:

Removing the nvidiaota.apk is the first line of defense

block the ota site both from your router and the host is a second level

You can also remove the partition named recovery

Depends on the router. You'll need to find your own step by step for your specific device.

Maybe silly question, but here it goes.

So having removed the TegraOTA, is there any chance that updating the Shield Hub, or another Shield app, will cause it to reappear? :confused:

[Shield Tablet General] Konstrictus:
You don't NEED to do that, since only the old tablet really needs to have tegraOTA deleted to avoid the kill switch. You can just leave the new one on stock.

There are some who prefer to delete tegraOTA on the new one for security reasons (to avoid forced updates...), but that's really up to you...
[Shield Tablet General] topcat36:
Delete TergaOTA. Better safe than sorry. That program is a security hole.

[Shield Tablet General] P00r:
Tegra ota is also the software who triger the OTA for a specific device, so by uninstalling it on the replacement you are actually reducing the chance of getting the silent update on the recalled tablet unless they decide to make it availlable for all rma'ed tablet...

It's an evil plan, they try to burn your house with a tablet then make silent update to remove all trace and send your a new device! :)

Is there any news about the kill switch in germany?

Because i got my replacement before 4-5 weeks and my old tablet is still working. The site "Shield Tablet OTA Check" said since then for my old tablet "Next OTA: None "

Or is it because i reset the Shield to factory settings before i first start the replacement so it will never be triggert?

Edit: No we don't have to send it back, itis not allowed in the EU to send damaged batteries in any way, instead we have to destroy it and throw it in the trash.
