So what am I looking for exactly? An error message saying feedback cant be sent to Nvidia or something? I went to setting -> about tablet and I see the option "send feedback to Nvidia." When I tap on the send feedback to Nvidia option, a little message comes up in the form of a letter/email. It shows (exactly);

Send feedback to Nvidia

You are safe to use the new tablet if the first option there is "Send feedback....". Is first is "Check for updates", your tablet is NOT safe.

How to get not-rooted old tablet to be used again?

Hello everyone! I have given the new tablet I got from Nvidia to my sister. It has already been activated and after that I did a factory reset on the old one, which I completely forgot about for some time. Now I want to start using it again to read books on it, browse the internet and watch Youtube videos and such, but I am afraid that if I connect it to my network, the kill switch will activate and it will be dead. Right now it turns on, I can use apps and configure settings, it just is not connected to the internet yet. :(

I am on 5.1.1 and not rooted but I am confused on what exactly to do. Could anyone be so kind as to guide me through the process of making it able to be used again without connecting it to the internet first (if this is possible at all)? I do not want to risk it being killed, because I would rather have a working tablet without internet than a dead one of course. :)

P.S. Please excuse my english, as it is not my first language. ^^

Look for guides to root this tablet. The same way you apply the zip from the first post on this thread. All you need is a computer. The tablet has to be offline from internet at all times.

If you search this thread, I put the link a few times.

If you are successful, in About Tablet, the first option has to be "Send feedback to Nvidia". Then you can go on internet safely.

Help With Rooting and Stock Images

Best thread ever: http://xdaforums.com/shield-tablet/general/stock-recovery-images-ota-library-guides-t2988881
[Shield Tablet General] swallman67:
Hey folks,

I'm looking to purchase one of these from a guy off Craigslist locally...he has indicated he has kept it offline since receiving his replacement tablet. I'm not afraid to root it, remove anything, etc. but what do I need for him to confirm with me to make sure it's not potentially about to be bricked immediately? Any warning signs, etc. I should be looking for to steer clear of it?

One concern I have - I've been reading a bunch of the posts in this thread and it sounds like I obviously need to get root (to delete the TegraOTA folder) and in the process the tablet will be wiped. I don't want it to try and connect to a wireless network while setting it up again. When it's "wiped" does that mean the entire OS is wiped or just user data? Can the zip be applied as a last step in the rooting process?

I have confirmed that the serial # of the device is showing as "ST - yy (urgent)" on the website...however, it still boots up fine currently. Anything I should really be concerned about? Just apply the fix and I should be good for now? It's a 32GB LTE model and he's asking $125 for it, I think that's a pretty good price...

Thanks.

only User Data is wiped when you unlock the bootloader, not the whole OS

Help

Hello everybody

I apologize for my English is not my primary language.

My problem is: I did not know the kill switch and my Shield has downloaded and installed the update automatically. :crying:

Now the tablet looks dead, but if I connect to the PC and I hold down power + volume up, I can hear the typical sound of USB connection in windows.

Is there a way to reflash the rom stock of the tablet?
[Shield Tablet General] Gizmo123:
Not until the SBK leaks, maybe someday, maybe never. Same issue here, i will keep the tablet in my drawer, hoping someday we get the solution to revive it.

Just want to say thanks to the OP for this...I was able to safely "kill the kill switch"...
[Shield Tablet General] Mr. Argent:
Hello! Outta curiosity... I've just picked myself up a K1. Do I need to worry about the ST-YY update even though i'm not using the older flavor of Shield? I've installed NoMoreOTA anyway just to be safe. Likewise, anyone know what the point of the ST-YY thing is? Force those with tablets that have defective batteries to RMA them?

EDIT: Ah, this doesn't seem to concern the K1 at all so far as I can tell and relates to defective original Shields being autobricked after activation of non-defective ones.. Maybe I was a bit premature in asking lol
[Shield Tablet General] anishrestha:
Hello,

I have an Inquiry.

I have got the Replacement Tablet and before I even opened it, I rooted and installed BlissPop Rom in the old tablet as it would make certain that Nvidia couldn't activate the kill switch. Then I turned on the replacement Tablet and both are working fine. But Blisspop is very laggy and drains battery very quick (like 100% to 20% in 45 minutes maybe). So I want to flash Nvidia Recovery Image for 3.1.1. in old tablet then remove tegraOTA.

If I flashed the Nvidia Recovery Image 3.1.1, then install custom recovery, then root and remove the tegraOTA all before I access internet, will I be safe?

Also, one more inquiry, if tergraOTA is removed then I do a factory reset on the Nvidia 3.1.1. Official ROM, will it come back?

Thanks.
[Shield Tablet General] topcat36:
Yes, you are safe to go online once TegraOTA is gone. Be 100% sure is not running before going online by checking in About tablet for the missing update option.

Factory reset does no bring TegraOTA back.

I just got my hands on my replacement unit but I have a question.

I installed cyanogenmod 12.1 on my old tablet to prevent it from killing. However, i want to use now my new one too. Is it safe to turn it on now for the first time or nvdia can still kill the old one along with the new one?
[Shield Tablet General] P00r:
It depend on the internal wiring since it is a battery you can have as an example 4 cell of 1250mA wired in parallel (internal connector would have 5 wire), then they would be charging at 1.7C or so. If the battery has less than 5 wire then your point is valid! The rate will not be much different, however voltage point may still be slightly different but this should have minimal impact on a battery life or safety.

I have read on an nvdia forum that there was a few case of fire, My battery when new (early 2015) was heating a lot, but with the most recent rom it is behaving well. I do suspect they changed the way of charging them with the various upgrade we had, as I did notice it is charging faster but lasting slightly less than before.

I was almost promised the eternal flame of hell :fingers-crossed: for saying that some old battery can be safely monitored or that newer Chinese battery may or may not be safer than the older one... Decide for yourself and like you did and ensure the battery behave correctly...

Charging a phone or a tablet on your couch or bed is not safe with any product or brand!

[Shield Tablet General] topcat36:
Android M came out for the K1 version. That is the newer version of shield that is identical to ours.

Since that model has no target on its back (killswitch), can't that version be installed on the old shields ?

Hello friends,

Today got new replacement nvidia sheild tablet 32 gb LTE. I haven't rooted my old tablet and still using it. I want to use new one also, so what should be my first step to safely use both tablets.? I checked next OTA for my old tablet, showing 'NONE'. If i need to install custom rom then please tell which is best?

Thanks!
[Shield Tablet General] Seba112PL:
Your tablet will be "dead" soon if you wont flash custom rom/ota remover. Disconnet your old tablet from internet as fast as you can and then flash it. After this you can connect it to internet and it should be fine.
[Shield Tablet General] jgigowski:
Is there an easy way to reinstall the OTA updater back on to the tablet without having to reload the entire OS from recovery? I removed the OTA from my replacement tablet, but would like an easy way to load the 6.0 update.
[Shield Tablet General] Medose:
ok, tell me please which custom rom should i install? I am confused between blisspop and cyanogenmod.
[Shield Tablet General] Seba112PL:
I cant tell you whats the difference between these two. On my old one im using blisspop for now and its working just fine. The only problem i can see for now is slightly worse battery time. What i would recommend for you... I think you should stay with stock room with deleted ota. At least for now.
[Shield Tablet General] Medose:
ok , how to delete tegra ota? tell me pls

Thanks
[Shield Tablet General] MusikMonk:
How about looking at the first post of this thread for starters?
[Shield Tablet General] Keithn:
If it has tegraOTA (which I am assuming it does) it has the capability of pushing the blank bootloader. If it sees that your device is supposed to be "killed" it will push it, this is based on serial# not rom. The new ROM won't flash anyway. The only way to be safe is to make sure there is not tegraOTA.
[Shield Tablet General] Medose:
yeah, i deleted tegra ota .. should i flash now tablet or its safe?
[Shield Tablet General] drewski_1:
Should be safe ?
[Shield Tablet General] Medose:
So now i successfully rooted tablet also with deleted tegra ota , but still on stock , did not put custom rom.

i can start using new tablet ? I think both should work fine ..
[Shield Tablet General] drewski_1:
yes, should be fine with the removal of the TegraOTA :good:
[Shield Tablet General] bradputt:
Hi there, I'm waiting for my new tablet to arrive, is there a need to remove the ota?

From what I see there's no reason for nvidia to kill my new tablet right?
[Shield Tablet General] drewski_1:
No, they kill the old tablet. That's where you need this mod.

[Shield Tablet General] P00r:
Some people got their old tablet deactivated, especially if the new one get lost in transit it would definitely be a good idea to remove the OTA apps, in theory there's not need but in practice some people had bad surprise.. since removing the TegraOTA is not causing any issue why wait...

Beside as Bogdacutu pointed out in his OP, this whole kill switch situation is introducing a real back door to having tablet deactivated by mistake or maliciously hence is recommendation to remove the tegraota on both the old and new tablet (removing from the new tablet also have the added benefit of preventing the kill swich being assigned to your old tablet) so there's really not reason to keep this thing in your tablet...
[Shield Tablet General] MAKAY_:
Mine got fried before I received the new one. I still haven't received my new tablet, btw. Nvidia is trying to find the one that was destined to be mine for almost half a year now. I told them that it is most likely lost. They don't listen. The problem seems to be that I'm in Europe and Nvidia USA doesn't care a rats ass.

The first thing I do when I get the replacement is to shut off the kill switch.
[Shield Tablet General] ms2048:

Would be amazing :> no fear anymore btw I removed recovery just in case if I need it I can installiert it in the fly using flashyfy is there a way to remove it on the go? Thanks guys
[Shield Tablet General] ms2048:
Thanks!

The reason I've been asking is that there was this guy telling that his tablet 'has been deactivated and now it only shows Android logo'. As it turned out, he has already sold it for some really low price, so I was a little late, but as I've suspected, it was probably fixable somehow...

[Shield Tablet General] sockusminimus:
Never mind, I answered my own question by pulling up a picture of the motherboard from a Shield Portable (which probably has a similar flash chip to the Shield Tablet) and the answer is no. Basically, a flash programmer lets you write directly to a flash chip regardless of any software controls in place. In some systems flash chips are surface mounted in a TSOP package and you can use a clip to interface with the chip from an external programmer. For the Shield Portable, which is what I actually found a picture of, the flash chip appears to actually be a KLMAG2GE2A eMMC FBGA QDP and thus cannot be easily removed/re-attached. I would assume that the Shield Tablet uses a similar chip. Someone with reflow equipment could remove the chips and reprogram them directly but this would not be cost effective at all.

Flash in twrp
[Shield Tablet General] AlexByrth:

Seems that Bliss Pop already comes without tegraota.apk, as I was unable to find it.

I guess nomoreOTA is only required for official images from NVidia. Is this correct ?

OTA BRICK

Is there anyway to unbrick the OTA update brick from NVidia? got tab from friend who got replacement and was unaware of OTA brick update, turn tab on and connected to my wifi , 5 mins later tab was dead and unable to start. only activity is yellow charge light by power connector.

any input will be appreciated.

[Shield Tablet General] topcat36:
I hope you did not pay money for it. No chance not to be aware, your friend, of the kill switch. With the new tab, he received a yellow paper stating clearly the old tab is on the death row. He should have told you.

Anyways, the tablet is a press paper.

'Death row" listing until I researched late last night when I noticed it would not turn on. Just figuring that if I can spend 100 or less for fix up it would be worth resuscitating tablet.

Hi

Have not switched my old tablet on yet since receiving my new tablet. My question is can I just boot straight into fastboot and flash custom recovery and supersu, then just flash the zip file nomore.ota

Or should I just flash a new Rom like bliss? Gaaps etc.....

Oops still on stock forgot to mention
[Shield Tablet General] PanchoPlanet:
Just don't log on with WiFi or network until you flash file. Logging on to a network is going to kill the tab.

Using your PC, download all pertinent files to root, install recovery then flash noota file, this will prevent the "kill" update from killing tab.

Hey guys,

So I received my replacement tablet a few months ago. I've been too lazy to migrate all my stuff from the "old" tablet, to the "new" one. That means that the replacement tablet has been sitting unopened, unpowered in its box and has never connected to the internet.

I was curious to check the status of the serial number of my "old" tablet on shield.bogdacutu.me and it states "Next OTA: none ".

(Sorry - new users can't post outside links)

Now I obviously know that my "old" tablet is part of the battery replacement program (I have the "new" one sitting at home), so why is the serial number of my "old" tablet not reading as "Next OTA: ST - yy (urgent)" ? Did the "new" tablet have to connect to Nvidia's servers first? Or did I just win the tablet lottery??

Any thoughts?
[Shield Tablet General] topcat36:
Same here. Only that I did open to test the new tablet before putting it back in the box for later and the first thing was to unlock and remove TegraOTA from it and then connect it to internet. For the old one there is no killilng update waiting.

In short, if the new tablet doesn't go online with TegraOTA active, the killswitch will not activate for the old one.

I would recommend to have TegraOTA removed from both tablets.

Hey guys sorry for my noob question but after reading for hours in this forum (so many pages), i got confuzed...

I will have my fresh new k1 next week... should i go into recovery to delete the OTA or with my boot into the home screen??

For example i want to debloat,root and multirom my shield. But first i have to kill the kill switch, right?

Can someone provide me a simple guide for a new shield user??

Thanks in advance

this is for the OG Shield Tablets that were recalled b/c of the battery issue so you could delete it, but it's not really needed for K1.

Hi,

thanks so far for your informations. When i enter the serial number of the old tablet which should be deactivated i got this reponse: Next OTA: ST - yy (urgent)

Does this mean is is not killed yet?

Anyway i already managed to get a response (with my serial) via fastboot that my device is connected to my computer but the bootloader unlock commands tells me "Failed: command write failed". How to continue now if it is not killed yet?

Thanks for any response.
[Shield Tablet General] Mojar7070:
When you get that OTA message I believe that it will "kill" the tablet the next time it is connected to internet with no approval. So no, it is not killed YET, but will be.

What command did you enter?? "Fastboot OEM unlock"

Thanks. So there might be hope...

I did it with small capitals but yes "fastboot oem unlock"

Keep your tablet offline from internet until you remove TegraOTA or you will have a dead one. That message means your tablet is marked for destruction.

So I'm correct in assuming, that my K1 that i just received today and updated to stock Marshmallow wont be affected by this kill switch, I checked /system/app and there is no TegraOTA folder or app. I just dont want to magically get an update that bricks my new tablet cause I rooted and flashed TWRP after updating to stock MM.

just added deleting /system/priv-app/TegraOTA in OP and nomoreota.zip, since that's apparently where TegraOTA is located in 6.0
