[NVIDIA K1] How can I flash to stock Nvidia ROM? - Shield Tablet Q&A, Help & Troubleshooting

I currently have custom TWRP recovery.
I've looked around, and the only tutorial I could find for the K1 is something that needs a file it doesn't provide.
Anybody here know how? (What commands to run, what to do in TWRP, what specifically to download, what to do with said files)

The official way is to download the recovery images and flash them with your PC.

SHIELD TABLET 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
Before flashing this recovery image to your SHIELD TABLET, connect your SHIELD TABLET
via USB to the PC where you downloaded this recovery image.
Next, put your SHIELD TABLET into fastboot mode using one of the following methods:
SW method:
- 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:
- Turn off the device
- Press "Volume Down" -> "Power", hold "Volume Down" and leave Power buttons till device boots
To flash this recovery image to your SHIELD TABLET, 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
Unlocking the Bootloader
Your SHIELD TABLET may have shipped with a locked bootloader. To update the device,
you must unlock the bootloader using the following:
- fastboot oem unlock
- Press the "Volume Down" button to select "Unlock bootloader" option on device
- Press the "Power" button to confirm the unlock. Your device's bootloader is now unlocked.

Strange instructions. Official ROMs should flash fine with a locked bootloader.. and last time I checked, there was a script for all these fastboot flash X commands.
I would hope that there are more accurate instructions in the actual factory image zip.

Sorry, I'm very new to these sorts of things, and didn't realize I had to unzip the files. I thought I just had to flash via TWRP like any other ROM.

This is assuming that you have Android SDK installed on you PC. - Tutorial found here:
http://www.xda-developers.com/android/adb-easy-tutorial/
1. Downloading the rooting-update zip file. Download the zip file from here - http://goo.gl/Om9aP
Now place this on your external sdcard. - Sorry this is a requirement at the moment, like I said this is a bit rushed.
2. Flashing recovery
1. Download this Recovery image. http://bit.ly/iLRAIV
(place this image in you SDK PlatformTools Folder, or which ever folder that contains your adb.exe)
2. If your device is locked, now is a good time to unlock it.
Code:
adb reboot bootloader
fastboot oem unlock
fastboot reboot
3. Flash recovery Code:
adb reboot bootloader
fastboot flash recovery recovery-Tiamat-R4c-100611-1150-cwm.img
Once you have verification on your device that this has been flashed, reboot your device by holding volume up + power. Then 3 seconds after you see the Motorola logo, hit volume down. You should now see "Android Recovery" in the top left corner. Hit volume up to boot into recovery.
4. Flashing the Xoom-Universal-Root.zip file.
If you're in clockwork mod recovery you can continue (This recovery image will say it is clockwork mod) . If you're not looking at clockwork mod, then you need to repeat step 3 again.
In cwm, go into "install zip from sdcard" -> "Choose zip from sdcard", then select the Xoom-Universal-Root.zip file you downloaded.
Note: use the volume buttons to navigate and the power button to select
Reboot your device and then welcome to your rooted device!
As Always, If this was helpful-hit the Thanks!

[Q][XOOM MZ604]No access to CWM Recovery

Xoom mz604 EU stock 3.0.1. Previously it ran US Andoid 3.0.1 DEMO Version (i don't know what this means).
Then i unclocked bootloader and installed EU 3.0.1. All was fine
I install CWM Recovery, reboot item, wait 2-5 sec, press vol.down button, but no "Anroid Recivery" title appears. Instead os this other options appear: "--> NvFlash", "--> RDS", "--> Fastboot".
So i have no access neither to stock recovery nor to CWM recovery. Xoom works fine, but i want to install Tiamat ROM...
What is wrong? Please help
Reinstall the recovery. Use this one. http://goo.im/devs/teameos/recoverie...ecovery-r6.img

No result. =( I wiped it, install new stock ROM (US version), then install recovery and nothing changes. The same titles: NvFlash, RDS, Fastboot
You have to boot it up from adb - type on your PC:
adb reboot recovery
It's done, good luck young man

Do this:
To download:
• Get the Motorola USB drivers to your laptop: http://developer.motorola.com/docstools/USB_Drivers/
• Get the Android SDK to your laptop: http://developer.android.com/sdk/index.html
• Recovery Image: http://goo.im/devs/teameos/recoverie...ecovery-r6.img
Steps:
1. Power off your XOOM device.
2. Press and hold the volume down button while pressing the power button at the same time. Note: Even if your xoom starts again, just keep the button pressed until you see "Starting fastboot protocol" on the screen.
3. Connect Xoom to your computer via USB.
4. Open a ‘Command Prompt’ or ‘Terminal’ window on your computer in your sdk/tools folder. This is the sdk you downloaded above.
5. unlock your xoom and flash the recovery image. The recovery image should be in your current working directory where you have command line navigated to:
Type:
adb reboot bootloader
fastboot oem unlock
fastboot flash recovery eos-recovery-r6.img
fastboot reboot
adb reboot recovery
Now, you have your device unlocked and recovery installed.
The above, will unlock your bootloader again and flash you the recovery...
Nice =) Thanks! +++

[Q] [HELP] Stuck on NVidia Boot screen

Rooted when I first got the tablet, was not using it much. Used Kingoo to remove root. On reboot it is now stuck at the NVidia logo.
When I reboot into recovery mode and select factory reset I get a CWM manager screen, select factory reset and reboot. Still stuck on the NVidia logo (currently in excess of 30 minutes.)
Any ideas?
Solved it:
Solution:
1. Register for the NVidia Developer program (I chose the gaming selection, not hardware). Takes about 30 seconds: https://developer.nvidia.com/gameworks-registered-developer-program
2. Download & unzip the Shield Software: https://developer.nvidia.com/gameworksdownload
NOTE: Make sure you download the correct version for your Tablet. WIFI, LTE-USE or LET-RoW (Rest of World). DO NOT FLASH THE WRONG ONE.
3. Download the Minimal Fastboot and ADB http://forum.xda-developers.com/showthread.php?t=2317790
4. Install the drivers for the shield from the NV download in step 2. The one PDF in the download is instructions (ish) if you need them.
5. Run the Minimal Fastboot and ADB installer.
6. Copy the contents of the fastboot folder to the NV folder from Step 2 (this is easier than editing the path for a single use).
7. Power off the tablet and connect it via USB to your computer
8. Hold down the Volume Down button for 3 seconds, press the power button and continue holding the volume down.
9. At the recovery screen you will see a menu. Look carefully. The bootloader will need to be unlocked. If it is locked see the note below. Select fastboot and press power. (I am not sure this step is required, since it returned me to the same menu, but it worked)
10. from the NV folder in step 2, double click "flash-all.bat" to flash the tablet.
If this did not work I would imagine that your boot loader is locked.
NOTE: To unlock the bootloader (Instructions are from NVidia directly)
Your SHIELD TABLET may have shipped with a locked bootloader. To update the device,
you must unlock the bootloader using the following:
- fastboot oem unlock
- Press the "Volume Down" button to select "Unlock bootloader" option on device
- Press the "Power" button to confirm the unlock. Your device's bootloader is now unlocked.

For a stock K1 (no custom recovery TWRP, etc.) I'd say the process outlined above is your best bet (restore stock recovery image).
I don't think you have to register to the Nvidia Developer Program anymore. Just go to the NVIDIA Download Center (as linked in the post above), find the right image, and download. Use search term "K1" and you should see the right image as one of the top few results. I believe version 5.2.0 is the last one that was released.
Once downloaded, flash the partitions using fastboot, as noted in the instructions.

Messed up my Shield Tablet

I found my Shield Tablet again today. I tried to install a costom ROM once, but I think I failed with rooting my tablet. The reason for this is, that i had no clue what i was doing.
I would like to have a fully functional tablet again, but i still have no clue what to do.
I try to describe the current status.
- I have a Shield Tablet 16GB Wlan with Android 5.1.1
- With Root Checker: No root.
- In the Bott menu it shows that the device is unlocked.
- There is a SuperSU app, but i get a notification , that the SU binary needs to be updated. If I do that it fails every time and tells me to reboot. After that nothing changed. Same Problem.
- There is a OTA Update, when i try to restart my tablat this comes up:
Root Access Possibly Lost Fix?
THIS CANNOT BE UNDONE
1. YES fix root (/system/xbin/su)
2. NO do not fix
After testing both, no changes
I tried to find a solution on my own for the last 3h, but I just failed over and over again.
Root access is optional for me now, i don't need it, but it would be nice to have it.
Could someone tell me what I should do? (Or post a link to instructions wich fits to my problems)
Thanks in advance
What version of software are you on? I recommend downloading the last Marshmallow recovery image available (for the original Shield, it's package 4.4), unzip the contents to give you the various images, and then flash using Fastboot. Just boot the tablet while holding down the power+vol down key, then release when the screen lights up. Plug into your PC, and run the Minimal ADB+Fastboot (google it, I think version 1.4 is latest).
Download site from Nvidia: https://developer.nvidia.com/gameworksdownload
Follow the instructions in the recovery package. Basically like this, assuming your images are in your fastboot directory:

[GUIDE] How to unlock bootloader on Nokia 3

*Unlocking bootloader will remove all your data!*
I'm using Windows 7, and that's the steps i did. (it should be simmilar for other systems too)
Getting code:
Code will look simmilar to this: DB1ED223C5537BA756FB0671E425D650
Method 1 (no root):
Go to
https://passwordsgenerator.net/md5-hash-generator/ copy paste serial number and click generate. Then you should see code in "MD5 Hash of your string". You can also go to simmilar md5 hash generator sites, but this site automatically converts small letters to big letters.
Method 2 (root):
Okay, this is new method that is much easier and you don't need to send IMEI and wait for @the_laser to give you code. Go to terminal emulator, type su and execute it. Then type this and execute it:

Unlocking bootloader:
Download platform-tools which activates adb and fastboot commands (first you need Nokia 3 driver installed if you didn't)
Nokia 3 driver: http://www.devfiles.co/download/3iK0k7Sv/Nokia_3_USB_Drivers.zip
platform-tools Windows: http://www.devfiles.co/download/KtLsN6fX/platform-tools-latest-windows.zip
platform-tools Mac: http://www.devfiles.co/download/OkrfluP0/platform-tools-latest-darwin.zip
platform-tools Linux: http://www.devfiles.co/download/vk5DudZX/platform-tools-latest-linux.zip
Enable usb debugging in Developer options before running adb. To get Developer options, go to settings, about phone and press build number 7 times. Also enable OEM unlock.
Now Connect phone to computer via usb and enable usb file transfer, run cmd as administrator, then type this command which runs adb:
chdir C:/Users/John/Desktop/platform-tools (this is just a example, you need to type your own location of platform-tools)
then type this command to check is your device connected to adb, it will show serial number of your device, if it hangs at waiting device, then you need to reinstall drivers (if you're doing this first time, then it will ask to allow usb debugging on your computer, just tick always allow from this computer and click OK)
adb devices
then type this command to reboot to recovery (you can boot to recovery by holding power on + volume up (only with usb connected) if this command doesn't works)
adb reboot recovery
when booted to recovery, choose reboot to bootloader option with volume sliders (this will boot to fastboot)
when booted to fastboot, it will show text 'FASTBOOT MODE' in down-left corner
now type this command to check is your device connected properly to fastboot.
fastboot devices
if it show characters like 0123456789ABCDEF or simmilar then it is connected properly, if it hangs on waiting device, then you need to reinstall drivers like mentioned above.
Android Nougat (7.0 & 7.1.1):
Now type these commands to unlock bootloader
fastboot.exe -i 0x2e04 oem key (type your key after oem key)
fastboot.exe -i 0x2e04 oem unlock
then press volume up, when asked
Android Oreo (8.0 & 8.1):
First download NE1-0-215H.lk.bin:
https://my.pcloud.com/publink/show?code=XZaLMs7ZclQ2wvKwSb0ofUraMmrsiHh6uk1X
Now type these commands to unlock bootloader
fastboot oem dm-verity <your_unlock_key>
fastboot flash lk NE1-0-215H.lk.bin
fastboot reboot-bootloader
Proceed your unlock procedure.
If you have problem on flashing the lk partition, you can use MTK Smart Phone Flash Tool to flash lk partition manually.
After lk partition flashed, you may encounter "Red State" when booting the phone. Ignore that and boot your phone to Fastboot mode directly with OST LA.
That is it, i tried to explain for you to understand everything i did to unlock bootloader.

@the_laser for codes, some additional steps and corrections. Also thanks for new method. @redweaver for new method.
@Hikari_kalyx for Android Oreo method. @bigrammy for NE1-0-215H.lk.bin link.
way to enter recovery without adb -
power off phone
press and hold volume up + power on buttons, insert cable immediately
countdown will start on phone, hold both keys until countdown ends, then IMMEDIATELY release power on key, still holding volume up
you will enter recovery shortly
after installing TWRP it is very important - DO NOT allow /system modification until supersu package installation ! ( or you will require reflashing phone with OST )
another note - can't enter recovery by combination volume-up + power button, if phone not connected to computer
one man reported, that even he successfully flashed TWRP image with "fastboot flash recovery <twrp image>", he still got original recovery.
workaround is to use "fastboot boot <twrp image>" - as we need to have USB cable connected to enter TWRP recovery anyway, not big problem.

Someone told me that if you flashed twrp, that it automatically removes data encryption. Is that true?
EDIT: i find out that is not true, it asks for some password to decrypt data, but the problem is that idk what is the password
DON'T install xposed! It bootlops.
EDIT: My fault, it actually work but you need to wait more than usual to boot.
That is great guys.
Do we have a working recovery yet?

I have stock recovery, but I use fastboot command 'fastboot boot recoveryname.img' when I need TWRP, and that's awesome because I don't lose stock recovery which is useful to flash OTAs and Nokia zips. I flashed SuperSu 2.79 just fine, but expect some crashes like software update, device monitor crash, but actually everything works, software update works just fine.

link for twrp
https://1drv.ms/u/s!AsmTb5aqoY12mDZqDZbPOp47QVMV
when downloaded, copy twrp to folder platform-tools and rename it to recovery.img
reboot to fastboot, then type this command:
fastboot flash recovery recovery.img
then reboot, fastboot reboot
if it didn't worked, use this command just to boot to twrp (you need to do this everytime when you are connected to PC)
fastboot boot recovery.img
To install root, first disable system modification on twrp then flash this zip for root.
This is not the latest version of SuperSU, but newest releases have some problems and crashes. (at least for me). This is last version that works for me.
That is it.
Thank you!
Is it possible after unlocking, installing twrp and root, to return the device to factory settings for ota updates? If so, how?

on twrp, there is a option wipe, click on it, then you will see option swipe to factory reset. then wait and reboot.
And you can now enable system modification if you want (it is recommended to enable it because some zips fails to flash because this option is disabled)
After installing TWRP and rebooting, does not want to boot Android, weighs in on the initial splash screen what to do
