Bricked Fastboot

***FIXED***
Update:
I was able to resolve this, here is what I've done in case others happen to have the same issue:
Turn on computer volume, reason being I had mine off and even though it appeared to skip over fastboot with the OTG method, it in fact was enabling for a sec or 2 then moving on as I could hear the USB connection chime.
NOTE: I had to press and hold to the LEFT of the Nvidia symbol until I heard the USB pick up chime, once I heard the chime I released my finger.
Prior to plugging in the power cord, I ran "fastboot boot <yourfilename.img>" and it sits at waiting for device...
Device took it and booted me into TWRP, I then flashed the Unofficial TWRP for the SATV, by choosing Image, then finding the .img that I already had on the internal storage
Rooted with SU, rebooted system and everything is now good to go.
Root, custom recovery and also Fastboot stock menu is back.
---------------------------------------------------------------------------------------------FIXED------------------------------------------------------------------------------------------------------------------
Hello All,
Long time lurker, now reaching out.
Just looking for a little help with my SATV Pro 500gb.
Here is the background:
Out of the box today, booted up and enabled ADB and jumped into fastboot for the bootloader unlock
Process took about 2 hours as the info said it would. Device rebooted, perfect working order.
Decided to flash TWRP for SU install along with possible custom roms, etc.
used this tool:
http://forum.xda-developers.com/shi...l-windroid-universal-android-toolkit-t3291266
Device said "please wait...." in fastboot screen, appeared finished and device rebooted into the the OS.
Here is the problem:
I go into command and adb reboot-bootloader, device reboots, I see the Nvidia logo and it boots into the OS, skips right over Fastboot
Shut it down, attempt the OTG, power cord ~3 secs over and over, hangs at logo and then boots in to the OS.
I reset the device, hoping the recovery OS would reflash the fastboot image, appears not to be the case.
Currently I am stuck with no fastboot access, device boots to OS no problems, but as far as fastboot is concerned I cannot access. Appears something went wrong with using that 1 click tool for flashing recovery.
Now before anyone chimes in, adb reboot-bootloader will not boot into fastboot and I've attempted the HW method listed on Nvidias dev site. Its 100% nogo.
Current State of device:
No fastboot
OS boots no problems
ADB works
No Root
Thanks for everyones look and help!

[Solved] I'm afraid I really bricked my Shield TV 2015

Hi everyone,
As mentionned in the title I'm afraid I bricked my Shield TV (model 2015, 16GB).
It was previously running StockRestyle 3.0 Marshmallow (from zulu99: https://forum.xda-developers.com/shield-tv/development/rom-t3321787) and all was fine with it.
But since Nvidia announced Nougat for the Shield TV, I wanted to give it a try.
Thus, I tried to flash the official recovery images from Nvidia, but I think I made the mistake to flash the Nougat version instead of the Marshmallow one.
So, here is what I've done:
- I copied the official Nougat recovery images on my PC in my adb folder
- I ran the flash-all.bat
- it started all right, but was then stuck for several minutes
- the shield TV rebooted itself but was stuck on the Nvidia logo
- after several minutes without change nor messages on the command, I quit the command terminal.
Later, I tried to start the process again without success.
Now, I can have access to the bootloader using the hardware procedure (long-press on the power button).
Unfortunately, it says on the top "Production mode: fused" (see the attached pictures).
From the bootloader, I tried "Forced recovery" -> I got a black screen -> Fail
I also tried the "Boot recovery kernel" -> I got the screen image with the android robot down with an warning symbol (see the attached pictures)
I tried adb and fastboot without success.
When I reboot the bootlaoder, with the shield connected to my PC with an OTG cable, the shield is detected but there is a warning message on my PC (it's not well recognized).
Also, "fastboot devices" returns nothing.
Technically, the shield is l still under warranty since it's less than 2 years old, but I'm afraid this "Production mode: fused" message would void it!
Any similar situation or suggestion?
Thank you in advance and have a nice day.

Hi, that production mode: fused is normal. I checked and I have it. I think it is there since I unlocked the bootloader. I run Full Android Nougat from @zulu99 without issues.
Do not keep trying to flash things just to flash. While you be able to boot into bootloader you can recover it (remember this) but is also true that if you mess with the bootloader you can brick your device. You're just soft bricked not hard bricked.
First, post the complete version of the bootloader, in the screenshot I can't see the whole version.
For later (do not attempt to flash anything until we go thru some checks):
Try with another known working USB cable and/or reinstalling fastboot drivers. And do not use flashall.bat, you will do it command by command.

That's what happens when you don't follow directions

Here is a picture with the complete version of the bootloader.
I followed quite well the instructions a year ago when I was trying to evaluate the pros and cons of Stock ROM, Stock Restyle and Full Android. Unfortunately @zulu99 posts have been closed since then.
Thus I forgot I had to revert back to standard Marshmallow first ;-(

I also tried two others USB OTG cables.
With on of them I managed to get "fastboot devices" recognizing a device, and I don't have this warning message on my PC (it's not well recognized) when starting the bootloader.
What should I do next?

Problem solved!
Since I guess the issue was mainly due on the suddenly defective OTG cable (it worked in the beginning of my last try, since I managed to flash some parts), I started the procedure again with with the official recovery 5.0.2.
- I started the bootloader using the HW method: long-press on the power button during powering up, until the bootloader appears
- Then,
* fastboot -w
- Then, again, I had to start the bootloader using th HW method
- Then, I followed most of the points described in the flash-all.bat files (except the adb commands)
* fastboot flash staging blob
* fastboot flash boot boot.img
* fastboot reboot
- Again, I had to start the bootloader using th HW method
- Then,
* fastboot flash recovery recovery.img
* fastboot flash system system.img
* fastboot flash vendor vendor.img
* fastboot reboot
- and voilà: I got Nougat running. Then the time it took me to enter my email credentials and so on, the OTA update to 5.1 was downloaded and ready to install.
A few minutes and a reboot later, I have the latest version running.
Thanks guys.

Your issue was the USB cable, if there is no good connection the flash can be incomplete thus corrupted. It is better to run the commands manually one by one so you know if it was successful on each flash or identify where it got stuck. Your lucky it didn't fail while flashing blob.
Probably failed after the boot flashing and fastboot reboot.
I suggest you get another USB cable, always use high quality cables. The internet is flooded with Shield TV users with TWRP, flashing issues and bricked devices because of a bad USB cable.

I tried doing the same thing and i got errors when flashing system and vendor files. It says that data is too large.

Shield tv is not working

Shield has Android TV 2017
I am following this process and the shield is not working.
—–
fastboot oem unlock
twrp boot (fail)
Infinite reboot
(controller a,b key pushing
power cable in)
hw mode bootloader connect to pc
(pc recovery img “fastboot-all.bat” Execution)
error devices not connect after install 2 things finished
—
shield tv Does not wake from sleep mode
pc to connect (pc devices manager display others-apx)
hw mode is not working
How can I recover it?

If your shield TV doesn't boot correctly, fastboot-all.bat won't work because you need to have adb working.
You should indeed rather follow the instructions given on Nvidia website, i.e. for Shield TV 2015 16GB with Marshmallow or newer installed:
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 reboot
Before that, be sure you use a good quality USB OTG cable.

Sounds like you can't boot into fastboot or bootloader mode.
If you can't, it means that you are hard bricked.
If you already had latest Nvidia experience version 5.1, there was no need to reflash the whole recovery image, PLUS you don't mention what recovery image you flashed.
To sum up your error was eather a bad usb cable (this a very known issue now, shield is picky) AND/OR wrong blob (which is the bootloader and it comes in all nvidia recovery image packages) flash.
What makes the device brick is a corrupted bootloader.
If bad USB and fail while flashing blob (which again is the bootloader), it gets corrupted.
If wrong blob flash (by using one that is not for you device model OR when attempting to downgrade to MM or lower bootloader), it gets corrupted.
Moral of the story:
Never mess with the bootloader a.k.a blob if you dont know what you're doing.
I know there are many hard bricked users around so better start reading. Take your time and make sure you understand all the instructions and also the pros and cons of the restore/unbrick method.
NOTE: just so you know next time for Shield TV 2017 , when you unlock bootloader and flash TWRP recovery or custom firmware you must root, because root with SuperSU disables some checks Nvidia run at boot. If you don't root, then your Shield will be stuck at boot.

Partition Flashing Issues, How Many of Us?

I'd like to get to the bottom of this fastboot/bootloader issue, that I'm having, others are having; on here, and on our Discord channel.
So how many of us are experiencing error flashing to any partition (manually, or using a script), in the past or currently?
An example, in my case, usually when I get the errors (which can be "partition flash failure" but has been other errors in the past.) I just change the usb cable, port, reset computer, etc, and it usually works. But lately the issue seems to be getting worse. Other times it took almost 10 minutes to flash one partition.
This morning I tried to flash a treble image and it failed on flashing 1/3 .... didn't even give itself time to try to flash it. It kept failing no matter what I tried. So a problem perhaps when mounting the partition.
Others might claim the partition is fried/failed/dead ... I don't think that's the case. This is why.
Sometimes calling `fastboot set_slot other` will fail. same goes for calling `fastboot getvar current-slot`
The other reason is this .... I was lucky and still had twrp installed on slot b, I was able to boot into the recovery on slot b and from there I could flash fine, could even flash a system image.
(as a note, if you get system mounting errors, your going to have to wipe system on the effected slot, and reboot back into recovery and start over)
So I'm asking this right now to all of you having issues:
1) What firmware are you on? I was on the prior oreo firmware (166)
2) what brand of type-c cables have you tried (i.e. essential, anker, etc)
3) what operating system have you tried? (windows 10, xp, ubuntu linux)
4) what is your computer's southbridge chip? (amd, intel)
5) are you stuck in edl mode? (on windows, go to your computer management/devices, and see what your phone is coming up as)
6) what is your fastboot version? `fastboot --version` (mine is 0.0.1-4500957 from google's android sdk)

Shield TV Pro 2015 - Can't connect through fastboot USB, suggestions?

(For the full story, check this thread over at nVidia support forums: https://forums.geforce.com/default/.../shield-pro-2015-can-t-get-it-up-and-running/)
Long story short, I'm trying to flash my nVidia Shield TV Pro 2015 with v7.0.2 recovery image, because I could not get past the initial nVidia "looking for experience upgrade", and thus not use the device at all.
I unlocked bootloader by fastboot, rebooted, flashed staging and boot.img, reboot (like flash-all.bat and nVidia Instructions says), but after the reboot neither of my two Windows 10 computers can recognize the Shield in fastboot mode as a USB device.
I've tried:
* Uninstall/ reinstall drivers through Device Manager
* Registry "hack" for disabling a check performed by Windows for USB devices (https://forum.xda-developers.com/android/general/fix-unknown-usb-device-device-t3375320)
Any ideas on how to successfully connect to it through fastboot, in order to finish the flashing process?
Are there other ways of restoring it, like putting a image to a USB stick, go to recovery?
