My shield won't boot, and every indication is that it needs to be reflashed with the system OS, per a few threads here. I can get to the fastboot menu, but I can't get adb to recognize the device. I have tried several rounds of adb drivers-the android SDK, the 2015 NVidia USB drivers, and the 2018 NVidia drivers. I used USBDView to verify that the Shield is connected to USB, and checked the VendorID and ProductID and verified that it was listed in the driver INF. Still, the adb utility doesn't show the device.
I'm in way over my head as far as trying to reflash this, and I'm hoping someone who has this device and already has success in flashing it might be willing to reflash it for me?
Fastboot and ADB are different, check you are connected VIA fastboot with a USB to USB cable. You should have fastboot in the same folder you are trying to ADB
To check connection
<folder> fastboot devices
To flash the firmware
Download the full recovery image here
https://developer.nvidia.com/gameworksdownload
Unzip to your fastboot folder
run the flash_all.bat
<folder> fastboot flash_all.bat
Be patient, it will take a while, do not unplug. Let it run its course and it will reboot when complete.
This should get it working, it did for me.

So I am having a lot of problems with trying to root my nexus 7. I'm pretty sure it boils down to a driver issue but I'm not sure. I have tried installing the correct drivers over and over again also uninstalling other hardware manufacturers drivers and I cannot get adb to recognize my device when it is shut off and in the boot loader.
When the tablet is on and I have debugging on, adb shows up and is recognized, however my problem is that whenever I reboot into the boot loader I lose adb recognition. So therefore I can't root or do anything else. Fast boot commands work fine its only the issue with adb.
If anyone has any suggestions as to what I can do I would really appreciate it. I don't know if its just a hardware issue or something I am doing wrong on my end.
This is also not my first time manually unlocking/rooting a device
When you initially connect, the device shows up as a "Nexus 7".
When you reboot into the boot loader, the device name changes, and there is no driver for that device.
As far as I could tell, I would have to do the root process under Linux to avoid this issue.
As for me, I just ignored the issue. By the time you reboot the bootloader, you are already rooted.
The only thing you do after the reboot is rename a file. For now I am missing that step...
Yeah I'm using windows xp. When its in boot loader it does change names. I can unlock the bootloader via fastboot but can't do anything with adb. Lol I don't know what else I can do, I'm at a loss.

Like I said - I think you are done...
Install a terminal on the Nexus and see what it says to "su". I use one called "terminal emulator". Works fine.
I think fastboot uses adb.
If you connect your Nexus, and type "adb devices" in a command window what does it say?
I believe it says devices attached or something like that. (Not at my computer) but doesn't give me a serial # like I think it should.
If you do not have USB Debugging checked, "adb devices" will just show the List of devices line.
If I set USB debugging on, "adb devices" also shows the Nexus serial number.
If you don't see that, I would double check the device driver you are using.
Under Device Manager, Android Phone, Android Composite ADB Interface it shows:
Driver: Google Inc.
Date: 5/24/2012
Version: 6.0.0.0
Digital Signer: google inc.
Well if I have USB debugging on and tablet on and do adb devices I get the serial # but once I go into boot loader and do adb devices I don't get the serial #.
For device manager I can choose adb interface or adb original interface. I'll have more info when I get out of work and at my computer. Do you have a link to the drivers you used? Or where to find them. Because I have tried a couple of different drivers posted around to no avail.
BTW thanks for helping me out.
I would not use any posted driver - you don't know where that thing has been.
Download the SDK from Google; the correct driver is in there.
Just point the device manager to it when you install drivers.
There are a lot of good descriptions on installing drivers in the other nexus forums
But - again - I think your device driver is fine. You will not be able to talk to the Nexus from ADB after you boot the bootloader
Bootloader has a different device name which ADB can't use under Windows.
Use Linux if you want to do that.
ok, so pretty much what happens is when my tablet is powered on with usb debugging everything is fine and ADB is recognized. Now my problem seems to be when i reboot into the bootloader it seems as though the drivers dont stick and it asks me to install the drivers again and this is where i have had all of my issues. When i type in adb devices in, it just tells me "list of devices attached" and wont let me do anything else (fastboot works). Like i said i was able to unlock my bootloader but i cant flash recovery or do anything else.
When i go into device manage to select the drivers it gives me the option of choosing between adb interface, adb bootloader interface, adb orignal interface and nexus 7 bootloader interface. I have tried all options and nothing seems to work. I have tried multiple usb cords and ports.
If anyone else has any suggestions it would be much appreciated.
I didn't read through everything but your initial problem is adb doesn't work in the bootloader that's where you use fastboot commands either boot into a custom recovery or just boot up normal and make sure debugging is checked.
Try running fastboot devices and see if it shows up. What you need to do is have bootloader unlocked and dismiss the super user zip floating around here pot that on sd card download cwm recovery image floating around boot into bootloader then
fastboot devices
fastboot flash recovery name_of_file.img
fastboot reboot bootloader
select recovery from the menu
Flash the super user zip
Or download a rom that has root and put that on sd card instead of super user zip and after doing the steps above then selecting super user zip select the rom you downloaded and flash. If you're on Linux run sudo first.

Trying to flash recovery partition.. as per many guides or http://forum.xda-developers.com/k3-...vo-k3-note-t3102997/post61860445#post61860445
adb sees the phone (adb devices)..
Reboots to fastboot..
But then fastboot devices reports nothing and fastboot flash recovery recovery.img just sits there <waiting for device>
Its like adb works.. but its not 'seeing' it in fastboot.
Phone is rooted.. I just need to get recovery partition changed to do backups and get a better ROM on there.
I faced the same problem and the solution was very simple. Make sure that you have downloaded the usb drivers corresponding to your PC's system type e.g., 32 bit or 64 bit. After downloading the correct version of the usb drivers make sure that you restart your PC. Hope this solves your problem.
Surely if I didnt have the right drivers already ADB wouldnt work ??
So am still getting exactly the same thing.. ADB works.. Fastboot doesnt..
Fastboot never seems to 'see' the device..
I have tried every set of USB drivers, lenovo drivers, minimal adb and fastboot drivers.. I can find..
What exact sets to making sure fastboot drivers are installed and correct ones.
After updating my shield tv to Oreo I successfully downgraded to 6.3.0 so that I could play PUBG mobile using octopus app. Well now that PUBG mobile detects the octopus app and bans players for using the app I wanted to go back to Oreo. I downloaded the recovery image 7.1.0 and got my device recognized by my pc windows 10. Ran the command adb devices and my device was recognized. I proceeded to run the adb Fastboot devices and my pc recognized my device. I then ran the adb reboot bootloader command. Then I ran the flash-all.bat command. This is where I’m stuck. My device is stuck in bootloader. My pc no longer detects my device when I run the adb devices or Fastboot. I am able to boot to recovery kernel on the shield. I have tried to apply update from adb but I think I’m not getting the correct files. If I select apply update from adb My PC does recognize my device as sideload. No Fastboot devices found. Please help me get my device back to Oreo or just operating.
Fix it
Hi did you manage to fix your shield as I have the same problem
I bricked my shield tv
I bricked my 2015 16gb shield tv. Powers up then turns off immediately
You must install the USB Drivers from NVIDIA, there is a separate driver that your computer needs to communicate while in fastboot/bootloader. So just because ADB works, does not mean Fastboot will work.
I have repaired several SHIELD TV 2015,And I can add shield TV 2015 storage。32G /64G /128G。Just need to replace EMMC.

My NVIDIA is dead ?no os no fastboot mod no adb and no recognize by my PC for install the drivers i have just the NVIDIA boot logo who freeze after booting
I want to install LineageOS so I closely followed the fastboot and adb instructions on the official site. During my first (failed) attempt, there were some old Google USB and ADB things on my PC, so I deleted everything and started again with a clean slate.
I managed to make ADB work (adb devices detects my device, could authenticate the computer, all seems good there). But if I start the phone in fastboot mode, connect and run fastboot devices, I get nothing back. It doesn't give any sign of the connected device. Windows's "Devices" window lists a device called "Android", but it's under "Unspecified" and has the yellow triangle/exclamation mark on the icon.
1. Am I right to assume that this will stop me from unlocking the bootloader (if I will use the unofficial method) and flashing TWRP and a custom ROM on the device?
2. More importantly: What could be wrong, how can I make fastboot see my phone?
Many thanks for the suggestions!
hi,
first do you have latest ADB and Fastboot
then connect your device and run adb devices. check if it detect the device means from the command prompt run "adb reboot bootloader" (without quotes)
now once after device reboots to bootloader check fastboot devices it will detect now
if not then goto device manager,right click on the device and click on update driver software and choose android fastboot interface
you are done now run fatboot devices,it will detect the device
Solved!

Hey guys, I know this isn't super active anymore, but I tried looking and tried posting elsewhere, and I can't find the answer I need. I'm sure it's something super simple I've overlooked.
I was gifted a 2015 Nvidia Shield TV Pro that was never used, so when I turn it on it gets stuck forever asking for my google login and won't proceed (like this thread here).
I can access the fastboot menu on the unit, and I've installed the PC drivers - BUT
When I open command and type "adb devices" it shows no devices connected.
I'm TOLD this is because I need to activate USB debugging on the unit, but how can I toggle on the USB debugging if I can't get past the google sign-in for a first-time set up?
Am I approaching this wrong?
PLEASE help!
Hello, I have exactly the same issue.
I would be really grateful if someone could help us.
i think you must set your SHIELD in FASTBOOT mode and after flash the stock firmware from https://developer.nvidia.com/gameworksdownload (you can't set FASTBOOT mode from ADB because of the wrong login)
to set fastboot mode look here : https://nvidia.custhelp.com/app/ans...invoke-the-android-fastboot-menu-on-shield-tv
Thanks conduisant! It helped.
I have spent some time to flash new recovery:
How far I was able to proceed:
I downloaded ADB Fastboot drivers
I downloaded recovery image (nv-recovery-image-shield-2017-atv-8.2.3)
I connected Nvidia Shield 2017 (model: P2897) with USB-A-to-USB-A cable to the PC
I was able to see "unknown device" so I installed ADB drivers (SHIELD_Family_WHQL_USB_driver_201801)
In device manager I can see my shield (as a Android Bootloader Interface)
I can access fastboot (pressing A+B on controller during turn on of shield)
I opened CMD and type "fastboot devices" - press enter - I can see my device is listed "03xxxxxxx fastboot"
I am able to execute "fastboot oem unlock", so bootloader is unlocked
I am able to write recovery image by using following commands written in instructions:
fastboot flash staging blob
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash system system.img
fastboot flash vendor vendor.img
fastboot oem lock
fastboot reboot
(no errors, everything was "OKAY")
But after the device restart , I can post only until the nvidia logo and that is it. Unfortunately I do not even know which was the original (stock) version of system in nvidia shield pre-installed. I tried to flash several versions of recovery images, but nothing helped. I can still see only nvidia logo :-(
But what I noticed, my Fastboot looks pretty different. I do not see my bootloader version, also some options are missing (lock bootloader, unlock bootloader etc.)
I also tried another options - boot recovery kernel, safe mode, but only nvidia logo every time.What is strange, when I turn-on the device, the Fastboot is automatically booted (I do not even hold A+B to initiate fastboot) I need to select continue.
So now I am not even able to try login into the shield anymore. I guess I already bricked the device :-(
what you have done is pretty correct !
Shield seems to be hard bricked, you can also try to flash TWRP + lineage OS ROM only to see if the SHIELD still not boot...i've no other idea
Thank conduisant for your effort!
Unfortunately, I am not able to boot into the TWRP.
I tried to flash TWRP what I have found here on forum:
UNOFFICIAL-twrp-3.0.2-ALL-Shields-build2.zip
But no success.
I tried to also flash official TWRP:
twrp-3.2.3-0-foster.img
But also no success.
I do not know which offical recovery to flash before LineageOS ROM (or it does not matter?)
Unfortunately, for some reason my gamepad in Fastboot stopped working (gamepad is connectied via USB to the shield, closest to HDMI port)
It just rumble when Fastboot booted and blinks blue led. I tried to charge gamepad - or - another nvidia shield gamepad but it does not work.
Also USB keyboard does not work. Looks like the USB port does not work properly anymore, so I am not able to click "Continue" in fastboot anymore to post at least until nvidia logo.
Luckily, the bootloader is still unlocked, so I am able to flash anything but I have already lost my mind.
I need another coffee and one full-day of meditaion.
i've got 2017 SHIELD, and i've flashed this TWRP last days + this LINEAGE OS : and all working good
TWRP = https://eu.dl.twrp.me/foster/twrp-3.7.0_9-0-foster.img.html
LINEAGE OS = https://download.lineageos.org/foster
when USB debugging is ON, only one USB port is activate for USB devices (keyboard for example) : it's the port near HDMI, the other port (near fan grid) is for ADB connection for the PC
