Hi

There is no need to flash the custom recovery if you don't want to. Just do a fastboot boot recovery <recovery.img>. I did that because i didn't want to change to another recovery.

After the reboot you will revert to stock recovery.

[Shield Tablet Android Development] eurominican:
Just to make sure, if you unlock the bootloader through "fastboot oem unlock" theres no way to reverse it in case need to send in for warranty repair, just like samsung devices with the stupid KNOX e-fuse? Or you can just revert everything (flash stock image/recovery and then fastboot oem lock)?
[Shield Tablet Android Development] Bogdacutu:
Unlocking the bootloader doesn't void the warranty (and even if it did, they would still be able to figure out if you've unlocked it before, even after relocking)

Help

Anyone else not able to download supersu.zip the page wont load
[Shield Tablet Android Development] Granger77:
NM sorry just went it opened instantly, maybe to much traffic
[Shield Tablet Android Development] cyraxx84:
Ofcourse you can relock and go to 99.999% stock. 99.9% bacause after un- & relock there will be a little sign which shows nvidia that your bootloader was unlocked but you can't remove it. But as far as i know it doesn't void your warranty!

root method LTE compatible

Hello,

I'm expecting a 32GB tablet (LTE/4G device) soon. Does your ROOT method work for the LTE model, or is it just for the 16GB (wifi only) device ?

Thank you.

Driver issues

I cant for the life of me get my win 7 64bit pc to install the drivers I've tried uninstall and going through manually with the naked driver method and it still says the device doesnt need it his tutorial is for win 8 am I missing something, I'm losing my mind over here I want this thing rooted so bad I'm losing sleep, and google has been useless
[Shield Tablet Android Development] eurominican:
Ty for info and reply.

Got it. Thanks!

Same here. I got mine on sale with the controlller. I suspect its the same on both wifi only and LTE version.

[Shield Tablet Android Development] stanglx:
Yes.... Follow it exactly and you will be fine... You must unlock the bootloader and either flash or boot into CWM recovery to sideload SuperSu. You can not install SuperSu from within a booted OS.. you must do it from a recovery (and not Nvidia's).

---------- Post added at 02:52 PM ---------- Previous post was at 02:50 PM ----------

No Problems for LTE...

---------- Post added at 03:07 PM ---------- Previous post was at 02:52 PM ----------

Load the Nvidia Driver in Windows first... get ADB Composite Driver working.. You should be able to ADB while booted in Android OS if you have USB Debugging on the shield tablet checked

If you have an exclamation point Uninstall (check off delete drivers if its present). You want to start clean.

#1

At the ! right mouse click and click update driver software. Browse to the Nvidia Shield Tablet Drivers (download and extract first ) folder. It should install. If not go to #2.

If all is good... reboot into fastboot..

The same driver should show as (if I remember) Fast Boot Driver (or something like that). If not repeat above (#1) while in Fastboot mode on your Shield. If that does not work goto #2

#2 At the ! right mouse click and click update driver click "Let me Pick from a List"

Uncheck

"show compatible hardware". Under Manufactorer find Android (at the top) then select Fast Boot or ADB Composite Driver (which ever is appropriate - if your in the boot loader pick fastboot if your in recovery pick ADB Composite Driver).

Make sure fastboot works in the boot loader and then ADB while boot in the Android OS.

Now reboot into the recovery (CWM, Nvidia, etc.)... Go to install from file (ADB - what ever it says to side load a zip)... If it doesnt work the driver will either have an exclamation, it may not even be called Shield Tablet, etc... Do #2. #1 almost never works.

Hope this helps...

ok I followed the steps but looks like my device is not rooted.

I followed the steps exactly and used the files as per the guide.

could it be because im on 5.0.1?
[Shield Tablet Android Development] nschneider350:
I do these steps after taking the ota 5.0 Lollipop update and then the 5.0.1? I am used to flashing custom roms on all my devices so I just want to make sure.

thanks
[Shield Tablet Android Development] NapalmDawn:
I'm curious about this myself. My shield is the LTE version and currently rooted and has a custom recovery. I believe, if I'm correct, that I would take the OTA and then reflash the recovery and use that recovery to flash supersu again. I'm fairly sure these are the steps.

I know over on the console version, people had been producing pre-rooted OTAs and you only needed to drop it on the sdcard and flash from your existing recovery.
[Shield Tablet Android Development] nschneider350:
So I didn't want to wait and I went ahead and OTAed to 5.0.1. I then followed these directions to get root. The only issue I had was after flashing custom recovery and rebooting to it I couldn't sideload the supersu.zip because it wasn't recognizing the tablet anymore. So I had to reboot and run through the setup of Lollipop, copied the supersu.zip to the INTERNAL sdcard, enabled USB debugging, rebooted back to bootloader and flashed recovery again. I then booted to recovery and installed the zip via sdcard. Everything worked great.
[Shield Tablet Android Development] Primetime_de:
Hi there,

is there any way to root a Shield with 5.0.1 installed without unlocking the bootloader and keep my data?

Thanks,

Chris
[Shield Tablet Android Development] oleg77:
and

Yes, use the OTA to get the 5.0.1 android, then you can root it. I have just done this with a new 32GB (LTE) tablet, no problem. Just be sure to install all the drivers you need for the device (USB driver and ADB driver). I was able to sideload supersu after installing recovery following this method, no issue as someone just had in a previous post.
[Shield Tablet Android Development] smiter:
nice guide, ty, just rooted my shield tablet

last point, if you have any problem with copying supersu.zip using adb, just copy it to sdcard a install from there.
[Shield Tablet Android Development] freakyfranks:
Thanks!

Great job on this. I used mine unrooted for a couple weeks and just couldn't take it anymore. Quick note, I had to rename my super user zip to su.zip for it to transfer properly for some odd reason. Now I get to mod my life away!!!!!
[Shield Tablet Android Development] NapalmDawn:
I don't like to live in a world where a device I have is not rooted :D
[Shield Tablet Android Development] freakyfranks:
This device has many lollipop bugs, and root is necessary to fix them; such as the volume increase/viper audio fix, getting rid of bloat, TBU, and such. I'm still getting system slow downs and lock ups with speaker squeal. Working on those!
[Shield Tablet Android Development] john09121:
Help

Can someone help me I live in the UK and I have just ordered my 32Gig LTE tablet from Amazon and it says it will come with Lollipop 5.0.1 on it, can you please tell me if this will work on the UK 32gig LTE Shield? I am sorry if this question has been asked before, please can you answer this for me.

Thank you.
[Shield Tablet Android Development] Thejimmynguyen:
Hey! Thanks for the great instructions. I successfully followed everything but I'm stumped on the last three steps. I got into CWM, chose install zip then install from sideload. Now, when I type in "adb sideload supersu.zip," I get a "device not found." Weird because all my drivers were updated to get me pass the primary steps. Any recommendations?

UPDATE: I tried to go into recovery without flashing the Supersu.zip. It asked me if I wanted to keep root and I said yes. However, Once turning on the tablet, root checker says I am not rooted. Drivers seem to be responsive now too. Only when I go to install the supersu.zip is when it says "device not found" and the driver on DEVICE MANAGER says I have to update the driver. Please help! Can't live unrooted. );
[Shield Tablet Android Development] NapalmDawn:
There's 2 different drivers needed when going though this process. The ones needed for ADB and the ones needed for fastboot.
[Shield Tablet Android Development] Thejimmynguyen:
My adb and fastboot drivers are all up to date! It was my Nvidia shield that didn't have the driver updated. For those who encounter this at the final steps, you have to go to device manager, find the tablet (it should have a exclamation mark), update drivers, browse computer for driver software, then "let me pick from a list of drivers on my device", then find MTP USB device and update it.
[Shield Tablet Android Development] An Droid:
If you've got cwm installed, why even bother with adb?

Just install the latest stable SuperSU .zip (copy/download it directly to your internal memory) directly from cwm.
[Shield Tablet Android Development] eurominican:
Worked great for me on a LTE tab! Loaded supersu with adb sideload as directed. I renamed it to su.zip maybe the spaces in the name causes issues?

Just chiming in to reconfirm these instructions work on the LTE tab and also used the recovery.img from the middle of the thread
[Shield Tablet Android Development] Latheman:
Is there no method of rooting on lollipop with no unlocked bl? I have mine on KK but I cont want to wipe mine by unlocking the bootloader.

[Shield Tablet Android Development] SuperPichu:
Look at my thread on the subject.
[Shield Tablet Android Development] Thejimmynguyen:
Putting in command: fastboot flash recovery recovery.img, but nothing changes. I tried to reboot and go into recovery but it has the android on his back. It says the download was finish on command prompt but yeah. Any help is appreciated.
[Shield Tablet Android Development] quixote:
No need to flash custom recovery

You can just "fastboot boot <recovery.img>" and then sideload / install supersu from zip

Worked fine for me & saves all those concerns about receiving new OTAs...
[Shield Tablet Android Development] Bogdacutu:
the recovery doesn't matter that much when receiving OTAs (it might not want to install the OTA, but you can force it), modifying the system partition (by doing things such as installing supersu) does
[Shield Tablet Android Development] Iorkca:
Just a quick question after rooting my shield with this method should i also install Busybox or is that not really needed?
[Shield Tablet Android Development] cyrax2768:
Anyone know if this method works with the new 2.2 OTA that was released tonight? I just got my tablet today and it updated before I could Root the device.
[Shield Tablet Android Development] masterchiefb117:
Yeah it will..... dumb down version is to get updated, then get into fastboot and flash recovery, then boot into recovery and flash super su
[Shield Tablet Android Development] cyrax2768:
I unlocked the bootloader and flashed the CWM but then had to reboot my device to get back developer mode. How do I get to CWM now to flash the supersu? When I did a adb reboot recovery it booted with the red exclamation android.

---------- Post added at 11:27 PM ---------- Previous post was at 11:19 PM ----------

Never mind i got it to work, just reflashed recovery in fastboot and then flashed supersu.zip thanks!
[Shield Tablet Android Development] thefiqs:
I got mine on friday. Bought used. Bootloader was unlocked already but restored to factory settings. Installed the official OTA 2.2 and today managed to flash CWM and SU. Everything is working so far. Thanks for the guide!
[Shield Tablet Android Development] HTC Tytn user 188:
I got mine last week and this week did recearch about this rooting etc. Discusted with nvidia support about it and they said go for it so i did. I followed first post but in sideload thing my computer first said wrong name and after i changed it it said cannot recognize file so i placed SuperSU to memory card and installed it from there. Everything seems to be working now. In the guide some steps was writtend little bit diffrently than it goes but not hard to understand what text mean.

I got some questions about future. Next time when OTA comes i dont update it. I wait for someone to make zip here and istall it in recovery. Does it delete custom recovery or how that works? Not big deal to do this again but just want to know how all goes easier. I dont also want to factory reset tablet very often.
[Shield Tablet Android Development] graffio83:
Hello,

tonight I'm going to do the root on my shield.

I never did and I downloaded the 2.2.1 upgrade via OTA, can I still follow this procedure?

In the future I will continue to receive and make OTA updates?
[Shield Tablet Android Development] FoxyDrew:
This procedure will still root your device.

You cant take OTA's straight from the tablet, however you can still flash official OTA's right away, through CWM or TWRP following this guide.
[Shield Tablet Android Development] graffio83:
thanks, but if I want, can I restore all and use OTA update?
[Shield Tablet Android Development] FoxyDrew:
Restore all? What do you mean?
[Shield Tablet Android Development] Keithn:
You need to be fully stock or OTAs won't work. I just grab the full OTA zip and flash in TWRP, no issues.
[Shield Tablet Android Development] graffio83:
Ok, but if in the future I want, can make my shield full stock and install OTA?

how can I do this?

there is a way to have both the root that the OTA?

How you grab all full OTA and how you flash it?

thanks
[Shield Tablet Android Development] Keithn:
Like I said, fully stock. The easiest way would be to flash the stock images through the bootloader using fastboot. If you want any kind of modification it's just easier to download a full OTA instead of incremental and flash in a custom recovery. Looking in the general section there is this thread with all of the stock stuff.
[Shield Tablet Android Development] graffio83:
Thanks, I already read this post but my questions is another.

can I obtain OTA upgrade file without using MEGA?

For example can I download it with my tablet but flash it with CWM?
[Shield Tablet Android Development] graffio83:
Ok, I foud the link to official nvidia upgrade page but I have only another question, when I flash new firmware, I'll lost all my data?
[Shield Tablet Android Development] chpimentelpr:
Works like a charm! Thanks.

It worked perfectly! Thanks for the guide man! :good: Running root on 5.01 android.
[Shield Tablet Android Development] Duckers McQuack:
When i choose "Load fastboot protocol" and enter it with the power button, the screen goes black and it appears again from the same menu like i didn't click anything.
[Shield Tablet Android Development] danjull:
That's what it does. Just type in the flash command in your terminal window on your computer.
[Shield Tablet Android Development] YuriPan:
When the title says "also locked bootloader" you just mean you have instructions to unlock it first? So there's still no way to do it without unlocking the bootloader?

Also one more question. Is there anyplace where I can see how to install the adb drivers? I've downloaded them but I only installed drivers for my older device 3 years ago and I'm having quite some trouble since I have no idea how I did it back then and can't find instructions on how to install the contents of this zip file anywhere... Sorry to bother you with this but if you could provide me with a link I'd be grateful.
[Shield Tablet Android Development] Duckers McQuack:
What's the flash command?
[Shield Tablet Android Development] FoxyDrew:
The flash command to unlock your bootloader which is "fastboot oem unlock"

Then the one to flash your recovery which is "fastboot flash recovery [nameofimage].img
[Shield Tablet Android Development] GuyInDogSuit:
Actually, I think I just skipped this step and the unlock command worked.

You need to unlock the bootloader to flash a custom recovery. No way around it.

As far as the drivers go, right-click on My Computer and select "Properties," then click "Device Manager" on the left. You should see an "ADB Interface Device" or something like that with a yellow triangle and exclamation mark. Right-click that and select "Update driver," then choose the folder you unzipped. It will automatically install. Now go to the command prompt and test with "adb devices." It should show the device's serial number. Make sure you turn on USB debugging.
[Shield Tablet Android Development] YuriPan:
I see. I am still worried about voiding my warranty although I mostly just want to block ads and backup my apps but I figured out a way to backup without rooting and I am trying to hold on without adblockers, at least until my device is no longer covered by warranty.

Thank you, your instructions for the drivers worked, I had tried that before but it seems like I had a wrong package of drivers, that's why they weren't installing!
[Shield Tablet Android Development] GuyInDogSuit:
NVIDIA's pretty lax about rooting and unlocking the bootloader. You can always relock and unroot if needed.
[Shield Tablet Android Development] YuriPan:
Really? I know I can unroot, I used to do it to my cellphone when I needed to have it checked but I didn't have to unlock the bootloader so I know nothing about that. If you can give me a link with info about relocking the bootloader please do. I had googled it to see if it was possible when I realized it was necessary to unlock it but I never found anything about doing it on Nvidia Shield...
[Shield Tablet Android Development] GuyInDogSuit:
There's a generic command for that, fastboot oem lock. Just like the unlock command. You can do this as soon as you restore stock recovery if you'd like. Or even after flashing TWRP. You'll have to unlock again if you want to update or restore, I believe.
[Shield Tablet Android Development] YuriPan:
But then won't there be a warning flag saying that the bootloader had been unlocked? And will the root remain? Oh just another thing. Will I be able to install Nvidia's OTAs from the update section in settings after rooting or will I have to do it manually? (I remember reading somewhere something about having to do it manually but I didn't pay much attention, it didn't matter much to me since I wasn't intending to root before my warranty was over.
[Shield Tablet Android Development] salespalace:
fabulous, works very easy. only issue i had was that busybox was not installed. so I had to manually install it using play store.
[Shield Tablet Android Development] MidgetMob:
Exactly. NVidia support will tell you otherwise and try to make you buy a new device, however NVidia's official stance is they are fine with rooting as long as you don't break your device in doing so. You can also cover up root completely in case of an RMA.

Thankfully their stance on unlocking is completely irrelevant. NVidia does not seem to care if you unlock your bootloader. This is fantastic as unlocking your bootloader is traceable no matter what you do to reverse it.
[Shield Tablet Android Development] YuriPan:
Hmmm, I see. I don't want to do anything too big after rooting anyway, I mostly want to get an adblocker and perhaps backup my files, although I found a way to do this without root as well.

In case I need to get it checked for some reason or another, do I have to undo the root and relock the bootloader even though they don't care if it's been unlocked, or is it alright to hand it to them with root?
[Shield Tablet Android Development] MidgetMob:
If you do have to get it checked/RMA'd, I'd recommend just flashing a recovery image and then relocking the bootloader (as long as your actions have not harmed the device). They might be okay with being handed an unlocked/rooted device, but wiping it clean and relocking the bootloader just makes it easier on you. Then you don't have to explain why you rooted/unlocked it.
[Shield Tablet Android Development] YuriPan:
Hmmm makes sense. After all I don't even know how I'd explain it because I live in Greece and NVIDIA has no service here so the device would be sent to the UK to be checked probably. Would be a hell of a mess explaining it >.<
[Shield Tablet Android Development] Mojar7070:
hello all,

i need a litte help. I was able to unlock the device but when i try to flash CWM with "fastboot flash recovery recovery.img" the dos console says "cannot load recovery.img" I've downloaded the Img file from the link in the OP and still nothing. I've also restarted the device and computer to see if that helped, but i didn't.

is there a step maybe I'm missing?? Thanks for looking.
[Shield Tablet Android Development] MidgetMob:
Assuming you're opening a command prompt where fastboot is located, did you copy the recovery.img to that folder?
[Shield Tablet Android Development] Mojar7070:
Hello,

Yes, I'm in command prompt. I downloaded the file to both the desktop and folder. However, it does not say in the tutorial to change the path of the file.

Should I close the original command prompt and manual chose the I'm file in a new window??

Sent from my 1+1

Edit: Hello, i figured it out. I just moved all the root files to the original path in the C drive. Noob mistake. I just assmused the it would be there. Thanks. [MENTION=6279337]MidgetMob[/MENTION]
[Shield Tablet Android Development] MidgetMob:
No worries, glad you got it.
[Shield Tablet Android Development] GuyInDogSuit:
For future reference, download all the required files into a folder (I have D:/Downloads/Android) and hold Shift and right-click in an empty space in the folder. You'll see the option "Open a command window here," which will automatically send you to that directory, so you can just type your commands (ie, "fastboot flash recovery recovery.img") from there.
[Shield Tablet Android Development] NapalmDawn:
Helium I believe can do this without root but I don't think it keeps the app's settings. I don't even know that, like Samsung devices, that the note keeps a flash counter.
[Shield Tablet Android Development] YuriPan:
I don't care about the settings in general, those can be set anytime, I'm used to setting up my tablet from scratch cause in my old one I kept flashing new roms to try them out so, all's good. I mostly want to backup my game progress because not all can backup on some cloud and it gets so annoying being halfway through some game and then having to start all over again.

And yes, it backups without root as well, but every time you reboot the tablet you need to do the whole progress again (connect the device to the pc with debug mode on and open the carbon software) before you're able to backup again.
[Shield Tablet Android Development] rusty.gh:
works!

Thanks much!

Key point I have not seen written anywhere before your post

"On the tablet, select "recovery reboot"

You should be now on CWM. Simply select "install zip from file" -> install from sideload

In the console, type "adb sideload supersu.zip"

Pick reboot, and say yes to save root
