Shield K1 Tablet isn't recognized by fastboot - Shield Tablet Q&A, Help & Troubleshooting

Good afternoon everyone
I got my K1 for Christmas and I've been trying to root it for a few days but I can't get that far because I can't get the bootloader unlocked.
I've been following the guide based off of Nvidia's website
I've activated USB Debugging mode as seen here . Now once I've authorized the PC using the tablet. Once I run cmd in administrator mode I run
Code:
adb devices
I am able to get the serial and it says it's authorized. However if I go into Fastboot. if I check for devices it just goes back to the prompt, and if I try to run the unlock command it just gets stuck on <waiting for devices> (I've attached a screenshot here.)
At first I thought this was an issue with the OS/Drivers because I am on Win10 x64, and the shield drivers gave some error about driver incompatibility. So I loaded up a VM with win7 x32. However I am running into the exact same issue once I get to fastboot; the tablet just doesn't want to cooperate. I've booted into fastboot manually Where the options are:
Code:
[nvtboot] (version UNDEF_BUILD)
[bootloader] (version UNDEF_BUILD)
Device - locked
Continue
Fastboot Protocol
Recovery Mode
Restart
Poweroff
Nothing is recognized from there either. I've also tried multiple cables, since the Shield doesn't come with any. Anyways I've searched the older threads here for help but none of them have given me any luck. If there's something I can try I would definitely be open to hearing it and trying, I just don't know what the issue could be.
Thanks for your time everyone.

You have boot into the bootloader before being able to use fastboot. Just reboot your device and hold vol- during startup. The tablet will show some console messages, offering some options. If you see that screen, you can use fastboot.

Adb works in normal mode.
Fastboot works in Bootloader mode.
Reboot to BL and type "fastboot devices", if no device go to K1 and select "fastboot protocol". Select on/yes.

Hey there, sorry for my late reply, I've been swamped with work. I've tried your advice with no luck so far.
I can reboot to the bootloader, but when I select "fastboot protocol" I don't get to choose Select on/yes. it just refreshes the screen with the same options that I listed above. If you'd like when I get home I can provide a screenshot of my tablet so you can see the options, but I'm not getting anything like you described. Am I missing something?
Thank you for your time so far helping me.

Connect k1 to pc, type in cmd:
adb devices
adb reboot bootloader
fastboot devices
/Enable fastboot protocol on k1, type again/
fastboot devices
Give here screenshot from pc - all command/answers in cmd. @bob3rt

I had the same issue and lasted untill I tried different usb cable
Shield K1 connectivity is very sensible to cable quality
try others

Hey Sorry again for a late response! However the good news is that I got it working!
What I ended up doing was hooking up the tablet to my Raspberry Pi with MATE and running adb/fastboot there. I originally ran into the same issue, but since I was able to sudo fastboot everything was recognized and seemed to work fine. I appreciate all of your help, and I apologize once again for the late replies!

For those that don't have a Raspberry Pi to follow the OP solution (like me), it's likely that your drivers aren't up to date on your PC.
Go here... https://docs.nvidia.com/gameworks/content/devices/shield_flashing_from_image.htm
And follow the initial instructions in the introduction paragraph and get yourself NVIDIA CodeWorks for Android. Once downloaded and installed you'll then see the shield in your fastboot devices list.
:good:

[Q] problem with rooting and drivers

Hi,
I'm kind of a noob at this rooting stuff. I've looked ariund, done my research and everything but it never seems to go smoothly??..
I think the main problem is with the drivers. After following instructions the android drivers still said 'Android 1.0'. So I installed Pda net and then I got 'Android ADB Interface' drivers. Soo the thing is, after searching for 'adb devices' in cmd prompt, It says 'list of devices' but there's nothing in the list....?
For some reason it won't do any commands like 'adb reboot bootloader' or 'fastboot oem lock'. It says not found. I have installed all the sdk and packages...
Would really appreciate some help from you guys. I didn't think rooting would be so complex??...
Thanks
can you post screenshot??
Ok for some reason, after starting the cmd again today and typing adb devices, it has listed my device. But when I type 'fastboot oem lock' (because my bootloader is already unlocked) it says not found as shown in the screenshot.
Am I doing something stupid??...

If adb devices lists your device you're not in the boot loader, the ONLY place fastboot will recognize your device and function or you have a driver issue. You're either in recovery or booted up. Reboot into the boot loader to use fastboot.
If you get into the boot loader and fastboot still doesn't show your device it's a driver issue. Update the driver manually and point it to the SDK USB driver provided with the SDK.
For reference....
Booted into boot loader:
Fastboot OK
ADB NO
Recovery / Fully booted
Fastboot NO
ADB OK
Hi guys,
I really do think this is a driver issue... any idea on how to solve it? I do have PDA Net installed... ?
@krohnjw ... could you please clarify.. Im a bit lost.
Thanks!
Did you try something like oneclickroot?
http://forum.xda-developers.com/showthread.php?t=1138755
Well I also had a lot of issues trying to root my i9020t so let me try to help..
Phone will be recognized with ADB when u select enable debug on developer options. You ll see "Android ADB Interface" on SYS DRV.
On other hand , when U start phone on fasboot mode, it should install something like "Android Bootloader Interface " , if U keep seeing "Android ADB Interface" , its wrong, but took some time to realize that.
That happened to me when I was using WinXP x32 to root my phone, ironically thinking it would be more compatible an less prone to bugs... When done it on W7 x64 , my fastboot driver was discovered correctly (Android bootloader Interface) using x64 PDA drivers, and all went good then!
Hope this may help!

[Q] Fastboot problem

hello,
I'm hoping someone here can help me sort out my current problem.
I've been trying to root so I can install the latest ICS port, but having problems at the Fastboot screen.
I apologize in advance if some of the references/names I'm using are incorrect.
So, I had originally unlocked my Nexus S sometime early this year. When I restart the phone, the "unlocked" lock picture shows up under the "Google" words, and when I go into fastboot mode, the Lock State is Unlocked.
I'm running 2.3.6 right now on the Tmobile version of the phone.
When the phone is on (not in fastboot mode), I can execute ADB commands and the device is recognized. As soon as I go into fastboot it isn't.
I'm running 64bit Win 7, and I have gone through the various threads that have listed this issue, and installed PDA Net drivers and still there is no solution.
In Fastboot mode, while connected to computer under device manager, it shows up under Universal Serial Bus Controllers as an Unknown Device... I'm unable to update any drivers for it, and even when I try to manually update the drivers by going to the PDANet drivers it does not allow it.
When the phone is on in regular mode in device manager it shows up as Android Phone and within that it has a listing called Android Composite ADB Interface.
As mentioned above, when phone on in regular mode everything is detected.
I installed clockwork app from market, assuming that the phone was "rooted" based on the "unlock state" in fastboot mode, but it immediately says that phone needs to be rooted because it was unable to find SuperUser file etc etc.
I've spent the better part of a few days trying to figure this out by checking all sorts of links, but I haven't found a solution. The main issue is that the phone is not being recognized when in fastboot mode when connected by USB. And I'm unable to install the proper drivers for fastboot mode.
Hopefully this makes sense, and someone can provide some insight.
Thanks in advance!
I'm not positive about this but couldn't you adb push the su binary and apk? I don't own the Nexus but I would think since its unlocked you could just push the files. If this would work I would think it's just a temporary solution to allow superuser permission. As I understand it, fastboot is the preferred method for the Nexus.

Did you try a fastboot command like fastboot devices?
Don't know if this applies to you but I had a similar sounding problem when trying to root my Nexus S where everytime I booted into fastboot mode I had an error message at the bottom of the screen saying something like 'fastboot status-fail Invalid command' and so I couldn't use any fastboot functions.
To get around it I used this one-click root . For some reason I got an error message halfway through for whatever reason and it wouldn't complete the root for me but it booted me into fastboot without receiving the error message and then once I was in I went and rooted manually.
The CWM is out of date on that site though (possibly the super-user zip too) so I replaced them with the latest versions and popped it in my dropbox for you, if you wanna try it out.
http://dl.dropbox.com/u/47770734/One-Click-Nexus-S.zip
Edit: just had a little look through the bat script and the initial commands that got me into fastboot properly is (with your phone in debugging mode):
adb start-server
adb reboot bootloader
Click to expand...
Click to collapse
So you could try that first if you wanna go through manually.
Know that you can't run adb command while in fastboot mode. Boot into your CWM and then you can start an adb shell and you'll be able to push all the files you want and execute all the commands you need.
Fastboot mode is for running fastboot indeed. Try 'fastboot devices' while you're in the bootloader and see if devices pop up. If not, you really have to figure out your drivers issue. Maybe remove the device completely from your PC (including driver files) and reinstall it using the PDAnet drivers.

Fastboot issues - Can't Get it to Work

I have a Nexus 5, returned to factory specifications (many times) with backup & restore inhibited. I am trying the “very simple” process of unlocking it, without any success. My problem is repeated many times on the web, Fastboot does not work, but ADB does.
I run the following command:
C:\adt-bundle-windows-x86_64-20131030\sdk\platform-tools>adb devices
List of devices attached
0315c2d60935c160 device
Then I run the following command:
C:\adt-bundle-windows-x86_64-20131030\sdk\platform-tools>fastboot devices
C:\adt-bundle-windows-x86_64-20131030\sdk\platform-tools>
ADB sees the phone; Fastboot does not.
The solution is well documented on the web: Install new drivers. I have been installing drivers from just about everywhere for the last week without success. With the phone connected, I get this from Device Manager:
Computer
Android Device
Android Composite ADB Interface
The driver information is as follows:
Driver Provider: Google, Inc.
Driver Date: 7/9/2013
Driver Version: 8.0.0.0
Driver Signer: Google, Inc.
Driver Details:
Driver Files:
C:\Windows\System32\Drivers\Winsub.sys (File Version 6.2.9200.16384(Win8_rtm.120725-1247))
C:\Windows\System32\WdfcoInstaller01009.dll(File Version 1.9.7600.16385 (Win7_rtm.090713-1255)
C:\Windows\System32\WinUSBCoInstaller2.dll (File Version 6.1.7600.16385 (win7_rtm.090713-1255))
I am running a Dell XPS-17 I7 laptop with Windows 8 (not 8.1) 64 bit
If I could find a way to unlock without using Fastboot, that would probably be a good solution, but I can’t. And I have absolutely no success at getting Fastboot to work.
I do notice that the Device Manager lists Android Composite ADB interface (ADB works) but noting about a Fastboot interface. Does that mean anything?
Please help I am at my wit’s end.
For what it is worth, I did read all the tutorials here, and the only thing I could figure out was if I have the right drivers everything works fine. I also reviewed the posts here, including "Diagnosing USB Driver and ADB issues in Windows," which discusses ADB (which I have no problem with)
this article helped me out a bunch. http://blog.dantup.com/2012/10/fixing-adb-device-not-found-with-nexus-7-in-recovery-mode/
you'll have to edit the "android_winusb.inf" with the correct hardware id.
in Device Manager make sure you go to "Android Device" > "Android Composite ADB Interface" go to Properties. on the Details tab and then click on the drop down box and select "hardware ids" you might see 2 ids there. i believe the one you'll need is the bottom one. if you only have one. thats fine too.
so, read the article. grab your hardware id and edit your driver. see if it works. you may have to reboot after you edit the driver. hope this works for you.

OK, please don't be offended, but I have to ask a really dumb question. You aren't running the "fastboot devices" command while in recovery, right? I read the above twice and didn't see where you booted into bootloader after running the "adb devices" command. Unless I'm missing something, fastboot won't find any devices unless you are in the bootloader.
Sounds like you need to boot your phone into fastboot mode. Power off the phone and hold volume down and hit the power button.
Then the fastboot devices command should work and you should be able to unlock the boot-loader then. Unlocking the boot-loader will wipe your phone just so you know.

Actually, the answer to that question is "Yes, and no." I was not aware that Fastboot only worked in the bootloader, but I could never get it to work there either. However, when I copied the previously posted listings I was not in the bootloader, I was in normal booted mode.
I then went and tried it in the bootloader, to copy listings to post, and here's what I got!
C:\adt-bundle-windows-x86_64-20131030\sdk\platform-tools>adb devices (In normal Mode)

OKAY [ 41.215s]
finished. total time: 41.215s
C:\adt-bundle-windows-x86_64-20131030\sdk\platform-tools>
As you can see it unlocked the phone but I have absolutely no clue why it unlocked this time and never did before. I hope to God I never have to unlock it again.
Also, it appears that in the bootloader, ADT is NOT working but Fastboot is! (now)
You realize that the two command line interfaces (ADB and fastboot) don't work in the same state, right? ADB is for use in recovery and while booted, whereas fastboot only works in bootloader. It sounds to me like everything is working exactly as it should.
I'm no expert or anything, but I always assumed that they were two different ways to interact with your device while it is in different states. If I'm mistaken, someone please correct me.

TF700 - unrecoverable botloader error

Hello
I need help with my TF700.
I had this tablet for some time. It was unlocked with TWRP and ZOMBI-POP.
Last week I wanted to upgrade it for KIT-Kass 7.1
I wanted to update my TWRP for kang wersion ( 2.8.7.4) through TWRP and during the process it rebooted.
Then I've got a bootloop on normal starting. I can't get into recovery mode through power + vol up - tablet has no respond for that
I can only go to fastboot through power + vol down but when I connect it to windows with adb drivers or to linux(FWUL) it sees no device and no respond for any command.
Do You have any idea what to do ?
Thank You in advance
Sorry to say this but, if you can't send it commands then you are most likely hard bricked. What OS are you running on the computer with fastboot on it? - NP

Thank You for the info, but I have laptop with Windows7 and still the same.
But if I have text on screen like this Starting fastboot USB download protocol can the device still be hard-bricked ?
Maybe I am missing some drivers ?
I would d/l Minimal ADB and Fastboot from here;

https://forum.xda-developers.com/showthread.php?t=2263822
For now the problem is I can not install the "naked driver" because devices manager can not see TF700 when it is connected, so I can't update the driver
Have you tried sending the [fastboot reboot] command to see if the tablet will reboot. When I bricked my TF201t my laptop didn't see it but it still took the commands allowing me to wipe the recovery partition and install the correct TWRP. - NP
Dear Guys
I know that this topic is quite old, but I am still fighting with this problem.
I tryied different drivers, 3 different computers ( two with windows 10 one with windows 7) and I can;t connect to fastboot.
The tablet is in this mode, but when I will use adb and type any command like fastboot reboot - it displays "waiting for device"
Do You have any idea what else can I try ?
Best regards
Hi,
me too! I was using it at lunch - no problem. Got home and turned it on and unrecoverable bootloader error.

Fastboot Mode bricked Acer iconia tab a700

I think I bricked my acer iconia tab a700. Every time I start the tab there only comes the acer logo and on the left upper corner there stands "Bootloader Version JB-653b3d3 (Unlock Mode)".
I know there is a thread about this (https://forum.xda-developers.com/t/acer-a700-bricked.1952590/) but that doesn't help me. If I follow the instructions of this thread to get into fastboot nothing happens.
Can someone help me how I can get into fastboot mode to connect the tab with my pc? Tanks in advance.
Fastboot deals with tablet's bootloader, whereas ADB deals with tablet's Android OS. What is really your goal?
BTW:
"Bootloader Version JB-653b3d3 (Unlock Mode)" states your tablet got booted into Fastboot mode. When in Fastboot mode no UI is presented to you: Fastboot is command-line driven.

My goal is to install an OS to use my tablet. I still don't found the OS but I think thats not the biggest problem.
If it states for that my tablet boots into fastboot how can I connect it with my PC because the tablet is rebooting after 15 sec. And if I connected it on my pc and typed "adb devices" in my command line nothing comes up.
If "adb devices" doesn't list your tablet ( connection type ) then may be USB Debugging didn't get enabled on tablet.
