What you must have
You need a unlocked boot loader instructions further below.
Also in cmw recovery, please wipe all partions! and reboot in to fastboot mode whilst still in recovery!
SHIELD RECOVERY IMAGE FLASHING INSTRUCTIONS
To follow the instructions in this guide, you will need adb and fastboot.
These tools are provided as part of the Android SDK:
http://developer.android.com/sdk/index.html
or you can just download this little .exe Minimal ADB and Fastboot this is what I used.please extract your recovery.zip into where you have installed Minimal ADB and Fastboot example c:\program files x86\Minimal ADB and fastboot.
https://docs.google.com/file/d/0B1S0LCuXCnnmSWh6NGJmSE1BUWc/edit?usp=sharing
Before flashing this recovery image to your SHIELD, connect your SHIELD
via USB to the PC where you downloaded this recovery image example same as above c:\program files x86\Minimal ADB and fastboot.
Next, put your SHIELD into fastboot mode using one of the following methods:
SW method 1:
- Boot to android home screen
- Connect the device to linux/windows system
- Open terminal (on linux); command prompt (on windows).
- Type "adb reboot bootloader" in terminal/command prompt
HW method 2 :
- Turn off the device
- Press and hold "Back"+"Home"+"SHIELD" buttons till device boots
To flash this recovery image to your SHIELD, run the following commands from
the directory where you extracted the recovery image package. If this is the
first time you have done this procedure, you must unlock the bootloader (see
below):
fastboot flash recovery recovery.img
fastboot flash boot boot.img
fastboot flash system system.img
fastboot flash userdata userdata.img
fastboot flash staging blob
fastboot flash dtb tegra124-tn8-p1761-1270-a04-e-battery.dtb <---------------------------------------------------------------------
Now restart your device
now wait a min or two and you have just returned to stock!
Unlocking the Bootloader
Your SHIELD may have shipped with a locked bootloader. To update the device,
you must unlock the bootloader using the following:
- fastboot oem unlock
- Press the Home button on the device to highlight "Unlock".
- Press the Shield button to confirm the unlock. Your device's bootloader is now unlocked.

Also worth noting that on Linux, you can install the "android-tools" package that gives you ADB and Fastboot anywhere.
For example, on fedora 20, run:
$ sudo yum install android-tools
Make sure you run fastboot with su- privileges (not doing this caused me no end of frustration before finding out why my device wasn't detected).

Umm having a little trouble unlocking. Am I to understand that you unlock with the device turned on ? because otherwise there isn't a home button...and where is the shield button ? I only have power and volume
buttons. This looks like the unlock method for the Shield not the Shield Tablet.

Your device should first be turned on. Then connect to PC and open a command prompt in your Android tools folder (where the ADB file resides) and type, "ADB reboot bootloader" (without the quotation marks).

Can I flash a ROW image in a US device?

[Q] Flashing a recovery to I9505 (jgedlte)

I've been trying during the last few hours to flash CWM/TWRP to my S4. Before starting, my phone was simply rooted (with CF-auto-root and Odin).
So I ran
Code:
fastboot oem unlock
and now I'm trying to flash with
Code:
fastboot flash recovery <recovery.img>
, but I keep getting the following error:
Code:
sending 'recovery' (9588 KB)...
OKAY [ 0.419s]
writing 'recovery'...
FAILED (remote: FAILSecure - Secure check failed)
finished. total time: 1.224s
(This one is from a run with recovery-clockwork-6.0.4.7-jfltexx.img, I also tried openrecovery-twrp-2.6.3.0-jgedlte.img and got the same error).
I ran
Code:
fastboot erase recovery
to see if it would help, but it did not do any better in the next tries to flash.
Now, I DID manage to boot into CWM with
Code:
fastboot boot recovery-clockwork-6.0.4.7-jfltexx.img
, but I rather flash it (Especially now that I erased the stock recovery.)
I also tried Odin and Heimdall, but Odin simply crashes when I hit "Start" and Heimdall fails to to communicate with my phone.
EDIT: Great. When booting with "fastboot boot", TWRP's touch doesn't work. CWM's touch doesn't work either, so I use the non-touch version, but when trying to install CM with ADB sideload, adb on my PC doesn't recognize CWM. What am I supposed to do now...?

You are giving him instructions for the I9505. I think he has a I9505G, so he should not follow your instructions. You are giving him a recovery for the I9505. The I9505G is a different model.
If Heimdall fails to communicate with your phone, then you don't have the correct drivers installed. TWRP doesnt have a non touch version. So my guess is that you flashed the recovery for a different device.

If the phone is already rooted just use ROM Manager or TWRP Manager apps from Google Play.
Both will just wipe out and overwrite any existing recovery image and replace it with the one you want. Problem solved right from the phone. No ADB shell needed.

Thanks guys. I managed to flash both philz (That link you gave me, although it is for I9505 and I do have a I9505G) and TWRP.
Both work, but besides them the phone is completely bricked.

If you can boot to recovery the phone is not a complete brick.
Once you are in recovery you can flash anything you want. You should be able to flash any new ROM and it will boot right up.

Just hijacking this post here to say, way to go buddy !
jk, reserved

Sorry guys, I know this is a very old thread but I've tried this so many times and did not work. My problem is that nothing happens in my device when I type the command to unlock the bootloader using Terminal.
I get the following message: Brunos-MacBook-Pro:fastboot Brunolima$ ./fastboot-mac oem unlock
...
OKAY [ 0.001s]
finished. total time: 0.001s
Brunos-MacBook-Pro:fastboot Brunolima$
And then that's it. It doesn't reboot and when i manually reboot it is in the same state as before.
Any ideas guys?

Hey, I've been trying the same thing. Didn't have your specific issue but I think it may be related to the fact that it's already unlocked.
That said, I to make everything work I basically used this guide + the commands from the official TWRP guide at the page "TWRP for OnePlus X" + the command from a guide in the official OnePlus guide called "[GUIDE] ONYX: How to Unlock Bootloader, Install Custom Recovery, Root, Take EFS Backup & More !!" --- sorry but I can't post links.
All in all the commands I've used where:
adb reboot bootloader
fastboot devices
fastboot oem unlock
fastboot oem device-info
fastboot flash recovery twrp.img
fastboot boot twrp.img

Yotaphone 2 soft bricked, step-by-step help

Yotaphone2 from china
YD206-> YD201
android 4.4.3-> Firmware 5.0.0-EU1.187a.zip
Hello, first post!
I bought my first android phone and ofcource tried to upgrade it to Android 5.0 Lollipop using yotaphone flasher program. I ended up to a jammed android logo ->softbricked phone..
The problem was finally solved by using fastboot program. You can find it in yotaphone_flasher folder, which you probably already have if you're in this situation.
So I do not recommend trying to update OS using yotaphone flasher, I would use fastboot, it is easier than you think and above all it seems to be the safest way to update as fas as i know.
If you want to know more about the fastboot: https://forum.xda-developers.com/showthread.php?t=2277112
This is a walkthrough made by androidnoob. Use at your own risk:
Download yotaphone flasher if you don´t allready have it: ftp://fw.ydevices.com/YotaPhone2/YotaPhoneFlasher/
Install yotaphone_flasher.exe and use it to download the firmware.
The default folder is C: Program Files (x86) / yotaphone_flasher, in that folder you will find fastboot.exe and firmware folder.
Copy the following files from the firmware folder to yotaphone_flasher folder (same folder you have fastboot.exe), you will need them later in the updating phase:
userdata.img
system.img
boot.img
Make sure that Yotaphone 2 is in downloading mode:
Simultaneously press the power + vol down until the display reads downloading. It may take more than one reboot so keep pressing until it appears.
Connect your phone to a computer via USB Cable.
Open the fastboot.exe. You can only do it in the command prompt, so press shift + right mouse at yotaphone_flasher folder-> Choose to open a command prompt. (Now you have to press enter after every command line)
In the command prompt, type the following:
fastboot
fastboot devices
If you see your phone's serial number, the connection works.
Start wiping memory, type:
fastboot erase system -w (this will erase everything, including your user data)
fastboot erase boot
And it´s time to install the update, type:
fastboot flash userdata userdata.img
fastboot flash -S 512M system system.img (For me installing in parts was a game changer. It´ll take some time so don´t panic)
fastboot flash boot boot.img
fastboot reboot
Yotaphone 2 will reboot. Wait 5-30 minutes, and the update is complete! Later my phone automatically updated 5.0.0-EU1.124b, so you can probably download this firmware using yotaphone flasher at the beginning of this process. I haven´t yet installed a sim so no idea if there are more issues.
This walkthrough has been compiled from various sources, so thanks to all for sharing! Hope this helps someone in trouble.

Yes, you can update your phone using manual fastboot commands. For convenience, a 4pda user rewrited YotaFlasher to a more polished version, making it flash system fastboot flash -S 512M system system.img command. I uploaded the new YotaFlasher in this guide.

You saved my day, the other methods did not work, I must add that it must be exclusively with the original cable, the others still with the error of "powered by android"

Hi, Could you tell me how to install the system.img in parts? I have a 1.4gb system.img file that I am trying to install on a bootlooping Yotaphone 2.
I keep getting a "Invalid sparse file format at header magi" when I do the second step, which I think is linked to the .img being too large. But I have no idea how to make it smaller. Thanks for any help!

SOLVED - Fastboot with no adb - any help?

Hi,
rooted 2017 16GB ShieldTV.
Unlocked bootloader.
TWRP was not installed just used to boot once and installed SuperSU (I feel like an idiot learning this only after)
Played with it - removed some critical system apps, and also managed to disable USB debugging (this only as I thought that TWRP was installed - and felt safe to do ANYTHING)
Now - boot to fastboot happens, but there is no adb.
Any saving method?
Original recovery gives options to ADB sideload and USB update.
Tried to use this by putting official Nvidia stock image on USB and but it reports signature failed, and refuses to flash.
Any help?
Thanks guys

SOLVED
Writting this as soon as I could cool down.
Situation:
- Shield ATV 16GB 2017. SW Nougat 5.2
- Unlocked bootloader (every boot gives that safety warning)
- System bootloop on Android circles animation (managed to root it previously and removed some critical apps by mistake)
- NO USB debugging
- NO custom recovery (as process for rooting only used TWRP to flash SuperSU, nothing else)
- Entering fastboot possible only by hardware method (controller connected by USB, hold A+B buttons while Shield is plugged off 10sec, then plug Shield in. Two short vibrations of controller and fastboot screen appears.)
However - NO adb in fastboot. (pinging with adb devices gives NO response). Only option that works is entering official recovery which gives options for adb sideload or update from USB. However - no zip file is accepted due signature check (and I tried tons of them)
Tools
1. Windroid
https://forum.xda-developers.com/showthread.php?t=2499926
2. Proper TWRP build
http://nvidiashieldzone.com/download/twrp-3-1-1-1-shield-tv/
3. Custom flashable rom (I used Lineage OS for Shield - lite and without Gapps - to speed up booting into environment that works). Put it onto USB drive
4. Oficial Nvidia recovery image (https://developer.nvidia.com/shield-open-source)
5. Minimal ADB and Fastboot (http://nvidiashieldzone.com/download/minimal-adb-and-fastboot/)
6. Nvidia controller plugged into USB port next to HDMI
7. Male-to-male USB cable (for ADB)
8. USB mouse
Process
1. Start Windroid and choose device (Nvidia, Shield TV)
Windroid will automatically download resources in Data folder (incl. TWRP that did not work for me), so dont block it with firewall.
2. Download proper TWRP from link above, and replace the one in Windroid Data/Recoveries folder using same name (Recovery1.img). You will notice difference in sizes. One that Windroid downloads is 25mb, while the one from link is ~ 16mb.
3. Enter fastboot on ShieldTV using hardware method (above mentioned with A+B buttons)
4. Now quickly In Windroid click button Refresh - and status will be updated to Fastboot
5. Then again in Windroid - click Flash TWRP and accept safety questions.
6. After successful flash - reboot into TWRP (here you need USB mouse - so you can unplug Nvidia controller, and plug mouse)
7. In TWRP - Choose Install - navigate to external USB and select flashable zip (Lineage ROM as above)
8. Once booted - enable USB debugging again. (you could be prompted on the Shield TV to allow your PC as debugging device, if so, say yes)
Getting back to full stock ROM with TWRP and unlocked bootloader
1. Install Minimal ADB and Fastboot you downloaded
2. Extract boot.img, system.img and vendor.img from Nvidia stock recovery image (leave other files out), and place these files into Minimal ADB and Fastboot folder (it is in Program Files x86)
3. While on (in LineageOS) connect Shield TV with PC using male-to-male USB cable
4. Start Minimal ADB from destkop icon and run following commands (commands are only in italic)
adb devices (checks if device is online. Its a must to proceed)
adb reboot bootloader (reboots to fastboot)
fastboot flash boot boot.img
fastboot flash system system.img (will take longer as its a big file)
fastboot flash vendor vendor.img
Once finished - reboot to TWRP, plug in USB mouse (instead of controller) to navigate, and perform Factory Reset.
If you wish to root you can do it via TWRP (which is what I did, flashing SuperSU previosly downloaded to USB)
Thats it - you are back from the dead!

Post updated - with process how to go back to stock

Thanks for this guide. It saved my ass!

Hi phnikola
thank you very much for your super instructions.
With this tool I could bring my TV Shield 2017 back to life, which got stuck in the Boot Animation.
I thought it was a trash can case, also contacted NVIDIA support to see what they were saying.
So I can also send the possible to me for the purpose of repair saved, thanks to you!!!!!!!!!!!!!!!!!!
