[Shield Tablet Q&A, Help & Troubleshooting] Xephrey:
Okay, this aint working.

Whenever I'm told to flash anything in recovery or bootloader, no devices are found. I can only see the device when it's booted up normally. I tried flashing stuff and booting from custom recoveries from normal mode, but it just gets stuck at 'waiting for device' even though the device is seen. I've been able to unlock my bootloader, but nothing beyond that point. I can go into bootloader from normal mode, but like I said, I then cannot see any devices once I'm in the bootloader. Something odd: I cannot do the 'hold power and volume down' trick. It just boots into normal mode when I do that. When I boot into recovery mode from normal mode, there's a android guy with a red triangle and I'm blind from the command prompt yet again. I have the drivers / adb / fastboot installed. I've tried this stuff in Yosemite and Windows 8.1. I'm all out of ideas.

Help me out, guys.

Thanks.

Yep! still on official KK towelrooted since its first week.

I wanted to load the recovery like you did, but I'd like to try with Philz instead of CWM.

Going to try again tomorrow...

Followed direction exact but tablet bricked

I followed all the steps exactly but after the final reboot, the tablet hang on a android logo. I waited for half an hour and it wouldn't do anything. I can still boot in CWM however am not sure what I should do next. should I try flashing a factory image (where the heck do I find one??) and start over?

---------- Post added at 05:00 AM ---------- Previous post was at 04:44 AM ----------

I went with the locked bootloader option btw.

Verified root, downloaded the update and did not install, load the update zip via CWM and flashed the superSU and adb flashed fine. First device I bricked =(
[Shield Tablet Q&A, Help & Troubleshooting] El Porcharo:
I didn't try yet (but I'm going to do it in a few minutes), but did you flash ALL the .IMG files including boot-root.img?

Which update zip are you talking about?

Anyway, you can find OS images here :fingers-crossed:
[Shield Tablet Q&A, Help & Troubleshooting] Frostbite0:
The Lollipop update file auto downloaded from nvidia. I'll try the OS images and hopefully that'll let me start over, should have backed up before installed the update!
[Shield Tablet Q&A, Help & Troubleshooting] El Porcharo:
I'm DONE!! :victory:

Apparently without problems!

If you can still boot to CWM, try the procedure again. I used Philz and after flashing decided to wipe the device: i don't know about CWM but Philz has an option called "Clean to install a new ROM" inside the WIPEs menu.

This means that I needed to reflash OTA 2.0 again with all the rest.

The procedure is not so difficult as I thought... Basically,

once you get to recovery

, the steps are as follow:

Install ZIP > browse your internal/external storage, depending on where you saved the OTA 2.0 > Flash the ROM zip

Install ZIP > browse your storage again to the place where you savede SuperSU > Flash the SuperSU zip

Go back to

Recovery

Main screen

Connect the SHIELD to PC via USB

From the command prompt copy and flash boot-root.img

adb push boot-root.img /sdcard/

adb shell dd if=/sdcard/boot-root.img of=/dev/block/platform/sdhci-tegra.3/by-name/LNX

From the command prompt copy and flash recovery.img (if you want to keep the custom recovery)

adb push recovery.img /sdcard/

adb shell dd if=/sdcard/recovery.img of=/dev/block/platform/sdhci-tegra.3/by-name/SOS

Reboot recovery (not necessary but I did to make sure it was installed properly)

Turn OFF the Shield Tablet

Wait a few seconds and switch back on by Power Button and be a little patient, because it takes a little to load up (I thought it was bricked then I went to the toilet and when I came back it was loaded to the "apps listing popup" :good:

I would try a hard reset if you're still in trouble, maybe check if you have that "Clean to install a new ROM" before starting the procedure above (make sure you do it

BEFORE

because it will

erase

your device, ROM included!!!!)

You should be done!

You had to unlock your bootloader to do the factory image flash. I assume you are now on kit kat, why not just do the ota via settings. Since you are unlocked once you are on lollipop install cmw then flash newer version of supersu, I linked the thread earlier. You should no longer need to flash the boot-root.img
[Shield Tablet Q&A, Help & Troubleshooting] Frostbite0:
I think the error there was the first download was not 2.0 but 1.21 upgrades. I did the OTA upgrades and it then ask for the 2.0 download and I did that upgrades as well. Whatever I did still seem unstable. Wifi went down first and when I tried rebooting the device crashed into the Exclamation screen. I can still reboot into the bootloader screen, but CWM does not load anymore.

Further more adb would no longer see the device even though the adb android device driver appears to be working correctly (I reinstall just to be sure). I like to start over with the factory image again but am not sure what I am missing here. I am not sure if USB debugging was enabled still after the update and if that is the cause. CWM appears to be corrupted some how, not sure if that could be a cause also. But I had flash factory once previously and the adb bridge was working correctly before. Back to square zero.

Step-By-Step Instructions - Unlock Bootloader - Flash CWM - Root

Hey guys,

I spent the whole day reading on how to get my nVidia Shield Tablet (with Lollipop 5.0) rooted. As I visited one thread it redirected to me to another thread and that thread redirected me to another thread because of all the pre-requisite steps you have to do before you can root the device.

I compiled this word document of step-by-step instruction on all the needed files, steps, and how to run Fastboot, disabling digital signature enforcement on Win 8.1, unlocking bootloaders, etc.

My nVidia Shield Tablet already had Lollipop 5.0 installed and was completely factory, no custom ROMs or recoveries were installed yet.

Hope this document helps someone and save you guys time. I take no responsibility of your guys devices if something goes wrong. I gave credit to the threads and developers. All my contribution is bringing the step-by-step instruction into 1 document instead of multiple threads. Enjoy. :highfive:

How do I flash SuperSU?

Can anyone give me a tutorial about flashing SuperSU 2.37 with CWM, please?

I need to root my Nvidia Shield Tablet OTA 2.0 because I want to install the dialer.apk and contact.apk so I can make calls.

My Tablet has the bootloader unlocked and it works fine but I don't understand how to make a recovery of SuperSU zip file and I also don't understand the instructions because they are too subjective and I think they don't explain well the process.

Thanks.

PD: I know it'll be awkward to hold the tablet in my hand while I speak to someone but I won't do that. Instead I'll use a pair of IEM's with integrated microphone.
[Shield Tablet Q&A, Help & Troubleshooting] mcord11758:
You don't make a recovery for supersu. You flash cwm following instructions from thread in development section then place the the supersu zip on the internal sd of your tablet. Get into recovery select install from zip then supersu.

[Shield Tablet Q&A, Help & Troubleshooting] chuck4100:
I am on LP, unlocked bootloader during KK, wifi version. CWM wont stay, gotta use the -fastboot boot recovery.img- after reflashing it each time.
[Shield Tablet Q&A, Help & Troubleshooting] CM17X:
If you are in unlocked bootloader it should be easy too root. I don't kept CWM by the way. By using the command "fastboot boot recovery.img" what you are getting is that the recovery gets loaded on the "ram", and will only work for that time till the next reboot. If you want to keep your CWM you need to flash the recovery with the proper command. I think is "fastboot flash recovery.img" or whatever name you gave to it menawhile you are on bootloader screen.

After that, sideload the supersu or flash it directly from your sdcard. For sideload it, make sure you are on CWM, and then select the option related to sideload. In your PC, place the SuperSu latest version on the fastboot folder and type "adb sideload supersu.zip" or whatever name you gave to it. If everything is good, it will start automatically.

Sorry for a simple question :

My SHIELD Tablet is already on lollipop with a locked bootloader and no root.

any simplest method to root the device?

And, if I unlock the bootloader, flash the custom recovery and then flash the supersu zip with it.

will all of the save data inside the SHIELD Tablet will be lost??

I'm having an issue when following the steps on this post:

http://xdaforums.com/showpost.php?p=57318831&postcount=136

I read the document, disabled the windows digital signature enforcement. When they ask to plug in my shield tablet which then installed automatically the drivers on my computer. The word documents says to uninstall the driver and then reboot to install the drivers from universal naked driver folder. The problem is that when I reboot the computer with my tablet still plugged in ( or even if I replug it after ), it re-installs the same driver automatically again showing in the device manger -> portable device -> SHIELD (never shows fastboot or anything).

Is that step necessary to unlock bootloader and continue further? D:
[Shield Tablet Q&A, Help & Troubleshooting] SuperPichu:
I would recommend using the drivers from here:

https://developer.nvidia.com/develop4shield
[Shield Tablet Q&A, Help & Troubleshooting] AvalonGEP:
So just to make I just plug in my tablet, let windows install the driver and install the one from the nvidia site on top to overwrite the current one? Because when i uninstall the current one and reboot, the driver re-installs again automatically.
[Shield Tablet Q&A, Help & Troubleshooting] SuperPichu:
If you remove the device from the device manager there should be a checkbox to uninstall the driver software. That should get rid of it. I would try unplugging the tablet, install the drivers from nvidia and then plug it back in.

Sorry I can't be more help. I do all my development stuff in Arch.

Flashing a few more times didn't work?

Hi,

I'm having the same issue after flashing the recovery.img, with the red triangle and exclamation mark. It shows up whenever I try to boot into my recovery.

I have tried re-flashing it several times and still with no luck. I also tried it via the locked bootloader method, but my bootloader is unlocked already and Flashify won't work unless my device is rooted. (Which is the whole reason I'm here in the first place lol.) I've also tried re-downloading the recovery.img and using that one, but still same results.

Any suggestions?

Thanks.

[Shield Tablet Q&A, Help & Troubleshooting] SuperPichu:
Try:

fastboot boot recovery.img

Sometimes it doesn't stick if you install it. That should make it boot so you can finish the process.
[Shield Tablet Q&A, Help & Troubleshooting] rogvid700:
So it did boot up! I flashed SuperSU and rebooted it, as well as selected "YES" when it prompted me to fix root. I verified that it in fact did work and I do have a successful root on the device, however CWM doesn't seem to have stuck. Whenever I try to reboot into recovery, the red triangle and exclamation point come back up again. The only way that works for me to get into CWM is when I do "fastboot boot recovery.img" manually through adb.

Any ideas as to why? Or if I'm missing something?
[Shield Tablet Q&A, Help & Troubleshooting] SuperPichu:
It's a quirk with the 2.0 update. Copy recovery.img to the internal storage. Then boot it via fastboot and run this on your computer while it is booted into CWM.

adb shell dd if=/sdcard/recovery.img of=/dev/block/platform/sdhci-tegra.3/by-name/SOS
[Shield Tablet Q&A, Help & Troubleshooting] rogvid700:
Neither ADB or fastboot can find the device after it boots into CWM for me to type command. And It's still plugged in to my computer.

[Shield Tablet Q&A, Help & Troubleshooting] SuperPichu:
Did the drivers install correctly? Open device manager and check for an unknown device. Unplug while the device manager is open to see what device disappears and let me know what it is coming up as.

No I meant while it was booted into CWM.

My apologies
[Shield Tablet Q&A, Help & Troubleshooting] AvalonGEP:
Doesn't seem to be working, I'm really having a hard time just to try and get the adb / fastboot to appear.

Every time I uninstall the shield driver then rescan or reboot, it automatically installs the driver like it was before without any "!" appearing anywhere.

Not sure what I'm doing wrong now. (btw running windows 8.1)
[Shield Tablet Q&A, Help & Troubleshooting] SuperPichu:
If you right click on the device in device manager there should be an update driver option that may let you switch if you choose pick from a list of installed.
[Shield Tablet Q&A, Help & Troubleshooting] AvalonGEP:
Alright, so I got it to work. Since I was only seeing the Shield tablet under Portable device and nothing else I decided to open USB debugging mode which allowed me to see the Fastboot(!) device and could proceed to unlock my bootloader and finishind installing CMW also.

Although from what i've read, I would need to download a boot-root.zip which I don't see anywhere. So i'm stuck there for now, I've already downloaded the SuperSU zip but didn't proceed further yet.
[Shield Tablet Q&A, Help & Troubleshooting] Prime170:
Hey guys, I'd appreciate a little help. I'm stuck unable to install the naked drivers (0.73), thus ADB won't/can't find my device. I have tried with both USB debugging on and off.

In the device manager with usb debugging off, it shows MTP USB device (with a yellow triangle on the icon). With it on, it shows 2 devices, the tablet and ADB Interface in Other Devices - which won't let me update the driver, in any of the 3.

[Shield Tablet Q&A, Help & Troubleshooting] rogvid700:
So yeah I double checked the device drivers and I just needed to reinstall the SHIELD drivers from Nvidia's website for the ADB interface to recognize the device while it is booted into CWM.

And I put recovery.img straight onto the internal storage, not sure if there is somewhere specific I need to be putting it in, but it's in the same place as the ClockWorkMod file.

I typed the command and got this result:

Does that mean it worked? Because it just looks like instructions rather than a confirmation. I'm wondering if I put the recovery.img in the wrong place, and if so, where EXACTLY does it need to go?

I double checked that I typed the command you gave me perfectly too.
[Shield Tablet Q&A, Help & Troubleshooting] SuperPichu:
It should go in the root of the internal storage. Run this and give me the output:

When I try to put the file in the /root/ of the internal storage, I get permission denied. I've tried pushing the file via adb, and using ES File Explorer on the tablet.

Also the command didn't output anything, probably because I can't get the recovery.img in the right place lol.
