hey guys. I have a demo unit.
Now before anything else, I should say that I looked at all three other threads on demo units, and that didn't help.
I looked at ThePooch's alternate method, and it didn't work.
In KFU, it gives the output of what is in the picture.
and in Soupkit, it says "permission denied" when trying to install either FFF or TWRP (I can't remember which, but if this is important, I will find out).
Can someone shed some info on what to do?
More pics are available to those who ask.

Use SoupKit to change the bootmode to fastboot, then install TWRP. See if that helps.

This could be the VMWare problem that you were mentioning in the other thread. upon reboot, VMWare says something to the effect that it could not connect to the kindle because it is in use by another program. I will try USB-Ubuntu in a few hours, but I think it didn't work last night, if i remember correctly.
I have witnessed one demo unit that was completely unrootable even with the use of a factory cable. So at the end it was only good for parts and the motherboard unusable.

when trying to switch bootmodes, Ubuntu just reboots the kindle. It isn't able to get into fastboot. If I could figure out how to take a screeshot of this I would, but I don't know how.
Anyways, I forgoed that, and tried to just do the TWRP installation and this is what I got:

openrecovery-twrp-2.2.2.1-blaze.img: OK
Checksum matched.

Do you wish to reboot into recovery now?
-- any ideas?
That`s pretty much what I experienced with the demo unit that would not root, it simply would not enter fastboot no matter which approach I took. I can take a look for you but I feel it`s pretty much a moot point if it wont enter fastboot. Power the device off, open a terminal
Code:
fastboot -i 0x1949 getvar product
hit enter, when it says waiting for device, plug the kindle in. if it does not enter fastboot and return product: kindle you are dead in the water.

That's the tricky thing about ADB and shell scripts. I won't go into too much detail, but part of that has to do with how ADB handles the exit status. Typically in Linux, an error results in an exit status of 2 (sometimes 1 depending on the type of error). ADB tends to have errors come out with an exit status of 0, which is why it said TWRP had been installed, when in all actuality it hadn't. The reason TWRP wasn't installed is because you need to either have root privileges, or be in fastboot, hence my previous instructions to boot into fastboot first.
In my opinion, your best bet would be to forgo the VM, forget about the dilapidated WinXP computer and figure out a way to boot your Win7 computer into Ubuntu from a USB stick. You are dealing with way too many variables to effectively determine exactly where things are going wrong.
I 'fixed' two demo KF's, messed up a lot on the first (lucky I didn't brick it).... On the second, I used a fast boot cable and installed TWRP, had a JB ROM on it in 15 minutes.
Try this.... Send TWRP to it using the command line, when it says 'waiting on device', open another window and get it to reboot in fastboot mode. On the first KF I found the utility would only put it in fast boot for a few seconds, but it was long enough to write TWRP if you did it this way.
Not sure why some won't work at all, maybe Amazon got smart on the demo units.

The above statement took place from USB boot, not VMware. Also, like I said, I attempted to set it into fastboot and it just booted regularly. I tried several times with different cables and ports with no success.

I will stick with my original idea no fastboot = no fun. You cant push FBmode manually because installation from unknown sources is disabled by default on a large percentage if not all demo units. Regardless if the device doesn`t enter fastboot not much you can do. Taking advantage of the small window of fastboot at boot is risky if the write time isn`t long enough to get it sent and written but it could be your best bet. IMO I would not attempt this with the bootloader only recovery no harm no fowl.
I have a 1st gen kindle fire.. That I rooted. But when i tried to install GAPPS and TWRP, the CMD window wouldn't let me. The error: "ADB server didn't ACK... Cannot connect to daemon" would pop up. So nothing else would load.
I then tried and tried various methods of fixes ( three days now), but none would work. Same constant error message in CMD window.
To make matters worse now, In one of my attempts to fix the problem, I've managed to brick the kindle. It's stuck on load page. Just says kindle fire on the screen.
ANY ANY ANY help .. would be greatly appreciated

There are 2 different types of commands sent from pc to an android device, adb and fastboot.
Adb is used when device is in recovery or system/Rom is running.
Fastboot is used when device is in fastboot mode or bootloader mode.

Step 3 says to put them all in the same folder on my C drive.
"Step 3: Place Files
Create a folder in c drive named adb,
unzip/extract files,
copy AdbWinUsbApi.dll, AdbWinApi.dll, adb.exe, fastboot.exe, fbmode, fff-u-boot_v1.5.bin, and openrecovery-twrp-2.2.2.1-blaze.img to adb folder."
I am sooooooo confused right now!!!
I was following step by step. I got the kindle to Root... but then it all went down hill from there. And now it's bricked. ANd I can't figure out how to get out of it.
As I said.. i've been trying for three days now.. All different methods.
I keep running into problems with the CMD prompts..
That is until I somehow bricked it. Now I can't seem to do ANYTHING on it.

One of the methods I was trying was this : http://www.androidauthority.com/how-to-unbrick-your-amazon-kindle-fire-46412/
However, once again, whenever it goes into the CMD phase, I get the phrase: "ADB server didn't ACK... Cannot connect to daemon"
So before I can unbrick it, I'm thinking I need to fix this other problem FIRST. The "ADB server didn't ACK... Cannot connect to daemon" problem.

It's not bricked it's in fastboot mode, where it needs to be to flash FFF and Twrp, the problem is your pc and the commands you are using.

Thank you so much for your help so far..
OK.. so I went ahead and tried step 6. Although the response didn't come back as it should have. I then went to the troubleshooting page and input:
If you got to step
Code:
fastboot devices
and do not get a proper code return, and you have checked drivers in Device Manager, or drivers don't seem to install correctly
you can try
Code:
fastboot -i 0x1949 oem idme bootmode 4000
then
Code:
fastboot -i 0x1949 reboot"
But now when i try to move ahead, the cmd window says it's waiting for device.
The Kindle at first looked as if it were going to reboot, but after a couple of times where the Kindle Fire logo went on and off ( at first disjointed then normal) . then it just stayed on that . Now underneath it says : Battery is too low ( 29%) . Please wait while your Kindle charges.
So I guess I just wait for it to charge? I'm not sure.
What do you suggest my next steps to be?
Again.. Thank you so much for taking the time to help me!

Well after a while , the Kindle Fire restored itself to factory.. Had me input all my info again on the Kindle.
So I guess one problem is fixed... It's not Bricked.
Is it still rooted as it was before the problem. And if it is, can I then install FFF and TWRP?
And Finally.. THANK YOU so much for helping me UNBRICK it in the first place!!

Did you use install.drivers.bat from Kindle Fire Utility? If not do so now.
Then watch my video, follow my written steps.
on the box my hpone came it it says H815, Made In Korea, I talked to LG they say it's registered in Hong Kong but it shows it's a LG-H815, No T or anything after the 8. So I have a H815. Not sure what the Hong Kong thing means...but I need to unlock the boot loader.
Following this: http://developer.lge.com/resource/mobile/RetrieveBootloader.dev?categoryTypeCode=ANRS
On the 'adb reboot bootloader' command it says in CMD, 'error: device 'null' not found'.
I've tried it many times. I can clearly see it as G4 in My Computer, I can go into it and see the folders on the internal memory.
http://i.imgur.com/fZ4t6Rj.png
http://imgur.com/5UBg6dB
I downloaded installer_r24.3.4-windows.exe from here: http://developer.android.com/sdk/index.html#Other
I installed the SDK Manger and installed the Google USB Drive and the Platform Tools, got the 3 files, did the cmd as you see in my image...
I never had to installed the G4 drivers or anything, it just installed it when I plugged it in and always worked.
So...?
Wish someone could help via Team Viewer..
Sounds like you need to install the drivers.... it is not so it just works for you to see the files... it is so that the computer will see the phone as an ADB and fastboot device
Install the drivers like it says to do, and test it by hooking the phone up to the computer and in a DOS box type "adb devices" without quotes, it should give you a device id.

Just to make sure I got the right drivers, can you link me to the latest drivers for the H815?
I tried: http://www.lg.com/uk/support-mobile/lg-H815 - makes me install that support program first, but once it starts up it tells me to select my carrier, which mine isn't there and lists models, which mine isn't there.. So that didn't help. The daemon thing is new though...

Start your DOS box from the directory you installed ADB to. If you do not know where that is, just search for adb.exe on your computer.
When you find where it is installed, just go to that folder and shift+right click and select "open command window here"
Run your commands there and it should work.

Just shows 2 empty lines, I need some real drivers or something. I don't know where to get them.
Read the thread about unlocking your boot loader. Everything you have asked is in it. Your phone needs to be in the right mode, adb, fastboot, download.
Don't know what thread your talking about and I've installed the best drivers I could find. It's not seeing the phone.
I opened CMD and did"
adb kill-server
adb start-server
Plugged it in and did the adb devices and got this:
C:\Users\Owner>adb devices
List of devices attached
LGH81567593392 device
Guess I'll try the next step in unlocked when I wake up. Any reason it has all those numbers after H815?
On the 'adb reboot bootloader' command it says in CMD, 'error: device 'null' not found'.
Normally, when it says "null" not found, you haven't accepted the connection on your phone, you wont see it if the screen has blanked.
Try again and accept connection from computer on your phone.
Oh, and if you;'re having problems getting the adb.exe etc to work, try downloading minimal drivers here ( http://forum.xda-developers.com/showthread.php?t=2317790 )and install to desktop with shortcut as well. When you click the shortcut, it will create a dosbox and most commands will work from there.
Sounds like it is working. The numbers are your device id. Just proceed with your unlocking or rooting now and it should be fine.
What should be my next step in rooting after unlocked BL?
In the end I want to update my firmware and install stock Android, that is if it's just the OS, no installed apps or anything, apart form Camera, Play Store, etc.

IF you have the H815 EU version, and were able to unlock the bootloader from the LG site....
http://forum.xda-developers.com/g4/general/unlock-bootloader-install-twrp-root-t3128241
Finish up on that page what you have not already done......
Install TWRP (recovery) and Root.
After that, its up to you, there are a few RoMs out that are stock and or debloated, pick the one you like.
Remember to check that it is for the H815 not a carrier version.
I am Trying to flash the stock rom via side load i flashed that few days back to at that time it was flashed success fully but now it always gives me error
Code:
"C:\android-sdk\platform-tools>adb sideload OnePlus3TOxygen_28_OTA_039_all_1701140132_de9036f11e2246a8.zip

Mine would not sideload either. I downloaded the zip file to my PC, connected the phone to the PC, put the phone in USB mode, dragged the zip file from the PC to the phone root directory, disconnected from the PC, and flashed the ROM from the phone hard drive.
Faulty ADB drivers I guess. If you have TWRP you can try adb push name /sdcard/

Second one is a invalid command because of those <> first command mainly happenda with wrong drivers, I and many other get the error it is quite unexplainable.

I ended up just removing the encryption, flashing twrp, and flashing OOS that way. Make sure to make a backup... I made a backup of everything... Except contacts because I thought gmail handled that like on my phone. I left my wife a note saying sorry for when she wakes up ha.
At least the annoying updates available message will be gone that we've had since Aug or something

Click on select executable and go to where your adb.exe is installed, for me it was in C:\adb\adb.exe
Then make sure the checkbox on step 2 is selected and then hit save
I rebooted my PC and upon using the adb on reboot I was finally able to flash the stock OOS roms via adb sideload on my phone

Well, now you can stop cursing at Nvidia, because they provided a way (albiet, a highly technical and mostly-undocumented way), to load any version of their OS that you choose.
I've seen others wanting to downgrade (including myself), so I've collected the relevant steps which I used to successfully revert to an earlier version. This guide assumes a bit of technical working knowledge, so I apologize if you are one of the 'normal' people that Nvidia has bulldozed over...
All the usual "don't blame me for bricked devices" caveats apply.... please be careful, know what each step does! research each step!
Best of luck...
0 - prereqs
make sure your PC & nvidia shield are both plugged into a UPS, b/c a power failure during a flashing operation is not very pleasant.
make sure you have (or do get) the adb & fastboot binaries ("commands") for your computer
make sure that you get all your userdata off the device, because it will be erased by this process
1 - using a web browser
register for an nvidia developer account (which you will have an opportunity to do if you attempt the next step)
download the 6.3 'developer os' rom for your particular model
https: //developer.nvidia.com/shield-developer-os-images (sorry, noob filter won't allow the real/clickable url)
NB: The 6.3 developer rom for the 2017 console is missing the userdata.img, there are currently no reports (on this thread) if a different userimage (pre-6.3 or for the 2015 version) works on the 2017 console (testers welcome!).
NB: if the cost of being identified as a developer offends you (i.e. yielding a name, company, email, etc), then you can probably dig up a link to the roms in the comments or elsewhere on the xda forums.
2 - on the device
enable developer mode by clicking the 'build' entry in settings->info
enable usb debugging in settings->developer-options
plug it into your computer using the usb port furthest from the hdmi port
3 - in a terminal
unzip the downloaded rom & cd into the resulting directory
edit the 'flash-all.sh' script to add the following line just before the final reboot:
fastboot flash userdata userdata.img
#(this will add even more wall-time to the flashing process, but will clobber the already-erased newer 7.0 user partition data with the old)
adb reboot bootloader
fastboot oem unlock && ./flash-all.sh
NB: Now confirm your willingness to lose all your data. On the 2015 'pro' version of the console, this is accomplished by pressing (or holding) the nvidia logo 'button'... AND WILL TAKE NEARLY TWO HOURS. Others use the x/y/a/b buttons on the game controller connected to the usb port nearest to the hdmi port.
[... time passes ...]
NB: the 7.0 to 6.3 was a clean backstep for me, but if you are going between other versions, I can see that this script might stall in the middle if the device does not come back up with adb services available... in which case you will need to enter fastboot manually using a hardware method.
4 - Break TegraOTA
You have now flushed the correct version onto your device, but we can't complete the setup process... if you were to try, the final step would immediately and automatically start downloading & applying the latest (7.0) experience update! Therefore, we must neuter the updater itself.
Still in the terminal:
adb root
adb remount
adb shell
# now these commands are run in the adb shell (technically on the phone through the PC terminal)
# the first path was the right one for me, but I'm putting here all the paths known to me in case you are using a different version
rm -rf /system/priv-app/TegraOTA
rm -rf /system/app/TegraOTA
rm -rf /system/app/TegraOTA.apk
sync
reboot
5 - you should now be able to setup and pain-stakingly reconfigure your nvidia shield to the way it was before you blindly trusted an OEM update without doing extensive research beforehand.
PS: if you fear that netflix or amazon-video will at some point stop working because of this process, you might wish to "fastboot oem lock" the device (knowing that an unlock will erase your user-data, but having the developer rom means you can always get root access via adb).
I hope you find this useful.
Thanks! I will be trying this tonight! I miss 6.3 and PLEX is BROKEN in 7.0!
Any idea if this can be done without needing a controller? My buddy has a shield TV but bought it used without a controller.

Plex is NOT broken in 7.0 i use it everyday.

I use it every day too... and since Plex v6.13, files fail to play after 3 seconds unless you run them a 2nd time.
It's a known issue that everyone is having due an acknowledged bug in exoplayer2 with certain containers like mkv. Since 7.0/oreo has plex v6.14 baked in as a system app, it's impossible to downgrade to v6.12 to get rid of the issue until Plex fixes it... and they've known about it for 2 months now. Since quantity has been their focus over quality lately, I'm not holding my breath for a fix.
The solution is to downgrade to 6.3, manually install plex v6.12, and turn off app updates.... so that's my plan.

I think it depends on the model. AFAIK, the newer 2017 ones need a controller (or possibly a USB keyboard) to confirm the userdata partition wipe.

Ahhh, good call. I'll have him try a usb keyboard.
doesnt work for me... i have a nvidia shield tv 2015. i tried with flash-all.bat
and im stuck after reboot. is there any other way?

What command did the script stop at? and how 'stuck' are you (i.e. can you get to fastboot?).
I imagine that if you started with the wrong rom, it would likely fail to boot.
thanks for the fast reply, i just manually installed it without the bat file
I went manually into the fastboot mode by unplugging the power pressing the power button and plugging it back in until fastboot mode comes.
then i typed
fastboot flash staging blob
fastboot flash boot boot.img
wait until the sound on windows comes then - adb devices
adb reboot bootloader
fastboot flash recovery recovery.img
fastboot flash system system.img
fastboot flash vendor vendor.img
fastboot reboot
and then it booted

How did you get past the forced update? I was able to flash 6.3, but it forces the update during setup and I don't have ADB access yet because usb debugging isn't turned on. Can't disable the OTA updates without it!
Basically I've successfully flashed 6.3 and am sitting at a working fastboot prompt. Not sure what to do from here.

Disabling the OTA update is step four, if ADB does not work, I would guess that you forgot to flash userdata.img in the previous step(s).

So you did what to get userdata.img? Created it in TWRP or something? It's not included with the recovery images... and this basically bypasses the OOBE/setup stuff?
Thanks man

userdata.img is inside the ZIP from the nvidia developer website, as can be seen here:
Code:
$ jar tf nv-recovery-image-shield-atv-pro-6.3.0-dev_rooted.zip | grep user
nv-recovery-image-shield-atv-pro-6.3.0-dev_rooted/userdata.img

No... not really. The userdata.img from the developer pack both (1) matches the 6.3 version (doesn't have any of the newer, potentially incompatible entries), and (2) has developer-mode & adb enabled by default.
So in addition to it probably just working better, flashing the userdata will let you get adb access, and thus break the OTA, and thus complete the setup w/o the update.
I thought it would boot up, but im still stuck on the android loading screen!
Ill try to reflash the rom again tonight.
update:
I got it to work now, without update having to update to 7.0.2
Code:
adb reboot bootloader
fastboot flash staging blob
fastboot flash boot boot.img
fastboot reboot
//waiting for nvidia logo and the Windows PC to make the connection noise
//otherwise you can check by typing
adb devices
// if it shows something then continue
adb reboot bootloader
fastboot flash recovery recovery.img
fastboot flash system system.img
fastboot flash vendor vendor.img
fastboot flash userdata userdata.img
fastboot reboot
once it booted it up, i went thru the procedure of setting it up with my network and google account, then the window pop-up "downloading version 7.0.2" then i followed the guide in the first post
Code:
adb root
adb remount
adb shell
# now these commands are run in the adb shell (technically on the phone through the PC terminal)
# the first path was the right one for me, but I'm putting here all the paths known to me in case you are using a different version
rm -rf /system/priv-app/TegraOTA
rm -rf /system/app/TegraOTA
rm -rf /system/app/TegraOTA.apk
sync
reboot
after that it booted up into android 7 with not OTA update notification.
thank you!
hello, thanks for the contribution, but when decompressing the image of developer 6.3 of shield tv 2017 I do not know where to get the file userdata.img, could you give me where to get it?

As I said in #13, I found the userdata.img inside the archive from nvidia (the 2015 "pro" version to be exact), and I don't know why it is missing from (at least) the 6.3 archive for the 2017 device.
If you are feeling adventurous, you can try downloading either of the 2015 zips, and use its userdata.img... maybe the 16gb one?
I would be eager to know if that works for you, since I'm unsure if the userdata.img can be mixed between different versions of the console...
JUST BE VARY CAREFUL to not mix up your directories and start flashing the wrong blobs & boots... that would be a recipe for a brickin', methinks.

I'm quite pleased to hear that it worked for you... (my first success report!).
Adb root
When I attempt to run the adb root command it just errors on me at the end, do I need to have the shield booted into setup for it to work?

You forgot to include (or even describe) the actual error message, so I can only guess as to what is wrong.
However, since "adb root" is the linchpin of the developer rom, I would assume that you did not flash a developer rom (or as indicated above concerning the 2017 model) are missing the "userdata.img", which could also cause this behavior.
