I'm attempting to flash clockwork recovery and can't get the phone to respond to fastboot devices when in fastboot mode. I've tried everything I can find with regards to the drivers (pdanet, usbdeview, etc) and I can get google's and pdanet's drivers working fine with the phone booted normally (responds to adb devices). The problem seems to be that windows appears not to even notice that the phone is plugged in in fastboot mode and does not appear in the device manager, making the manual installation of drivers an impossibility.
Anyone know how to fix this?

When I first set up ADB and Fastboot on my pc, I was getting a response when writing 'adb devices' in the console. However, 'fastboot devices' returned absolutely nothing.
Solution (with phone connected to pc and usb debugging cheched):
1-shut down the phone
2-press and hold Volume Up key + Power
3-once in bootloader interface, in the pc command prompt, type 'fastboot devices'.
Voila!
By the way, don't mount the phone as usb storage device.
Thanks for the responses guys but yes, USB debugging is enabled and yes, I've used that way to get to fastboot mode as well as adb reboot bootloader
Hi stoo
I have a same issue - did you managed to find solution for yours?

easy way to set up fastboot
Any solution
Have the same problem: locked bootloader, not rooted 4.1.2. In ADB everything is ok, drivers ok (in device manager), can get it through "adb devices". But when I boot in fastboot (adb reboot bootloader), I hear the ti-da windows sound (usb unpluged - from adb session), but no ta-di when the phone re-boot in fastboot. No exclamation mark in device manager, nothing. The USB receive nothing when in fastboot. Is it possible that the fastboot image is corrupted? Can I reflash it? Or any other advice?
Thanks
EDIT - SOLVED - at least this step
The problem was the famous "broken power button"! I knew that I had problems with the power button (didn't work - that's why I try to flash a rom (4.2.1 or customized) with sleep tile in notification area).
I thought that the button is all the time OFF and don't switch to ON, but I finally understood that when when I boot in fastmode it freeze before installing device on the PC (I also had no volume up / down navigation in fastboot, a sign that it was frozen). So I ended to consider that the power button was permanently in ON position. I opened my phone and I measure the impedance on the power button. I had ~ 4ohms in off position of the button and 1.8 ohms (cheap multimetter.... probably should be almost 0) in on position. I measured also on volume switch where I had ~ infinite on off position, so I concluded that the button if blocked. I tried to see if I can resurrect it but no choice, so I took it off (unsoldered). I put the battery and the USB cable and boot it. From ADB I reboot it in fastboot and voila! The device popped in device manager! One problem solved! BUT...
I tried to use the Nexus Root Toolkit and it boots in fastmode and try to unlock the bootloader, but it asked me on phone screen if I agree for unlocking. I was able to use the volume to select Yes but I couldn't choose it with power! I had no option but to take the battery off. Starting from that point it was almost impossible to power it again. When I plugged the USB it shown the battery icon (charging). I tried every trick that I found on web, but nothing worked (even to fast plug / unplug many times the USB to overcharge it, but nothing). I was able only by pressing on the middle of volume (so Up and DOWN in the same time) and plus the USB to get to the screen of unlocking bootloader, but without the options YES/NO on the screen. Seems that it saves this state between boots, but why no option? Finally I was unable to boot at all, and it is like totally bricked
I thought that the power button is a simple switch ON / OFF, so I soldered 2 wires and I tried to touch them (short circuit) to simulate the ON, but nothing happened. Is it the button more complex that a simple switch? no ideea...
So now have a better phone than before (at least theoretically it should be able to fastboot), but it values zero because I can't power it on....
OK So I am in the exact same situation.
Nexus S, Broken power button, adb can see the device, fastboot cannot. fastboot cannot be navigated with the volume keys.
I also want to put an other rom onto it, but firstly I want to put TWRP recovery on it, as it supports touch, CW needs the power
button which like mentioned does not work.
I would rather not unsolder my power button to get into fastboot, any suggestions on how that might still be achieved?
thx

Yes, it should have been better for me to have also a possibility to enter in fastboot with the power button blocked in ON position, but I didn't find. And now I know no way how to power it up...
fastboot drivers

Hi,
I'm trying to sideload the final 5.0 build to my Nexus 5.

Your usb drivers are not installed correctly, reinstall the drivers and enable usb debugging in developer options. Check if you succeeded by typing in cmd (while the phone is in fastboot): fastboot devices. You should see a serialnumber if all went well.
Hi, @ibz100. It actually looks like your drivers are installed properly. At least your ADB drivers. You only use ADB while booted into the android OS, or from recovery. However, while you're booted into the bootloader (also known as fastboot mode) you'll want to use "fastboot" commands.
So boot back into the bootloader either the same way using ADB while booted into the OS, or from a powered down state hold Volume down(-) & Power keys. You can also use both volume keys + power to access the Nexus 5's secondary bootloader.
Once in fastboot mode, run the command
Code:
fastboot devices
If your serial number appears like it did for ADB devices, then your fastboot drivers are successfully installed. If not, then we need to get your fastboot drivers set up.
Read here if you need to install them. Feel free to reply here if you're having trouble installing them and I can help you through that as well.
Also useful: http://forum.xda-developers.com/google-nexus-5/general/noob-read-adb-fastboot-how-hep-t2807273
If your drivers are properly installed, run the command "fastboot" without quotations to see a list of available commands to be used in fastboot. If you're still not sure what to do, just ask.
If you want to use ADB to apply the update.zip, boot into recovery mode (I'm going to assume you're using a stock recovery). Use the commands I mentioned above to get to the bootloader. Now use the volume keys to navigate from "Start" to "Recovery Mode" With Recovery selected, key the Power button. You should see a picture of an android with an exclamation mark with the text "No Command". From there hold down the Power button and tap Volume UP(+) once. This will boot you into stock recovery mode. From there use the volume keys to navigate to "Apply update from ADB". Power key to select.

Try loading koush's universal adb drivers I was having the same problem but this solved it for me. Sidelosd worked a treat and running lollipop without problems so far...
Thabk you everybody, I'll try your recommended (re)installation of my fastboot drivers later and get back to you if I have any further updates on my situation.
Big thanks for all the replies guys, I really was taken aback by the sheer effort you put into helping people around here. Rest assured that it doesn't go unappreciated. Keep up the good work!

Well I've had my fair share of driver issues. I blame my PC. Anyways, I know how frustrating it can be.
However going back to what I said before, since your ADB drivers are properly installed (being as your device ID showed up and reboot bootloader worked) I wouldn't think it's too far fetched that you already have fastboot drivers installed. Before you try deleting/reinstalling them, I would first boot into the bootloader and run the command "fastboot devices" (no quotes). If you device ID shows up in fastboot, there's no need to mess with your drivers.
Again, the reason ADB "stopped recognizing your device" is because you booted into fastboot mode. While you're in fastboot, you need fastboot commands.
If you boot back into the OS, or into recovery, ADB will recognize your device again. That's how it's supposed to be.
So power down the phone. Hold Volume Down(-) & Power until the phone boots into the bootloader and type;
Code:
fastboot devices
If your ID shows up in a similar fashion to the way it did in your screenshot, you're golden. Let us know how it goes! :good:
Hello everyone!
I'm trying to root my Shield K1 (Android 6.0) since hours, without success because:
I have no acces via adb. Im using the latest adb and also the right drivers (see picture) but I alwas get the message "unauthorized" in adb.
I can't boot my tablet into fastboot mode. When I press the power button + volume up to come into the menu and I select fastboot protocol, the tablet just starts again into the same menu - so i don't get into the fastboot mode. Pressing the powerbutton + volume down don't works either.
I have tried already almost everything: uninstallig drivers/reinstalling it, factory reset on my K1,...
So how I can root my phone without adb or fastboot? Can anyone help?
Even the recovery mode is broken I think, after booting into it, the green android with an red triangle is shown.
Is there something wrong with my K1?
PS: In the menu, which is shown after pressing power + volume up, is standing:
[nvtboot] (version UNDEF_BUILD]
[bootloader] (version UNDEF_BUILD]
Device - locked
You need to enable USB debugging in the developer settings and then allow debugging access from your computer by accepting a popup on your tablet.
Yes, I know this and I did this of course. But there never poped up something on my tablet.
So I also resetted the debugging setting, wiped the tablet, but nothing helped.
1. Sometimes the micro USB cable you use can be bad so I would suggest trying a different cable (especially since you have a K1 which doesn't come with a charger or cable).
2. Fastboot mode is that screen with the menu, that's why "fastboot protocol" just takes you back to the same screen. Also, recovery mode on the stock tablet just shows the android icon and triangle, so your recovery mode is fine.
I would suggest booting the tablet into android (so not the fast boot or recovery mode) and connect it to the windows PC using different cables until the authorisation pop up come up.
I am having the same issues as the OP, the only difference is my bootloader says "unlocked."
I was able to get authorization from the computer, no issues there, however fastboot will not find the device and neither will adb when at the "fastboot mode."
I'm trying to get fastboot so I can flash a recovery, but no luck to this point.
Anyone have any ideas or suggestions?

Thanks so much mate! :good: That's the sentence, that helped me. I didn't know this menu is already the fastboot mode. So if one know this it's quite easy to proceed.
Problem solved - tablet already rooted
The adb access is still "unauthorized" but doesn't matter anymore.
No problem, glad you you got it sorted.
It's odd your ADB access is still unauthorised, but at least it still works.

Just as an FYI....I got mine working. Needed to reinstall the nvidia drivers... Got authorization, etc... so assumed working and as we all know assuming is bad!

I can imagine that you all are tired of reading this headline, but seriously, ME TOO.
I have been looking for information about this issue during several weeks and I have not found any solution, so I would extremely thank you if you take your time reading this problem and trying to help me finding a solution.
Some months ago I tried to flash a ROM on my Shield Tablet, I followed all the steps from a topic in this forum: [Complete Guide] SHIELD Tablet K1 Root, Custom Rom and Xposed Framework but I wanted to try a different ROM: CARBON-CR-5.1-MOO-WEEKLY-shieldtablet-20170216-0454 (the name of the file) And now I have a tablet that is stuck on the Carbon launch screen every time I turn it on, when I press volumen down + power it goes into the screen buttt as soon as I press recovery mode the only thing it does is to restart itself and stays stuck in the NVIDIA screen. The Minimal ADB and Fastboot do not recognize the tablet with the adb devices command.
When I turn on the tablet (and stays stuck into the IOS icon as I mentioned before) and connect it to the PC the device manager recognize the tablet as a Portable device with the name: MTP USB device, when I press the power+volumen down the PC recognize the tablet as an Android Device -> Android Bootloader Interface. And this is all the information I have about my problem...
May you help me?
Thank you in advance. I hope your knowledge will help me and other people with the same problem. If you need more information of this problem let me know and I'll answer ASAP. If you have any idea tell me and I'll try it.

Your device is not, dead, it's only taking some time to reflect
First of all, I understood that you're able to access to the device's bootloader menu, through the button combo (black screen with white text, "continue","restart bootloader","recovery mode"), and you selected "recovery mode".
Now, unless you have flashed a custom recovery, there's nothing to do with the shield's stock recovery, so, just enter in the bootloader menu as you did, without selecting any option.
You are now in "fastboot mode", in order to check your device's connection you have to write in the adb shell
Code:
fastboot devices
If you see your device you can now boot a custom recovery that will help you to fix the problems you caused, I would follow this link: (copy-paste, can't post links)
"nvidiashieldzone.com/shield-tablet/shield-tablet-root/root-shield-tablet-v1-marshmallow/"
And do the 8th step, in "Root procedure"
Fastboot with TWRP
Type “fastboot devices” Copy and make sure your Shield Tablet is visible.
If your Shield Tablet is listed, type “fastboot boot twrp-20151227-EXPERIMENTAL-shieldtablet-m.img” Copy (or whatever you named it) and hit enter. If your TRWP image filename has a space in it, you may have issues.
After 15 seconds or so (be patient), you should see the TWRP Recovery screen. Note: This experimental version has some UI issues, just keep at it.
You may be prompted with something to do with the system being READ ONLY. Accept the default and swipe.

Use fastboot to wipe cache (fastboot erase cache) then try to flash TWRP (with fastboot) again. This will often clear up issues with being unable to boot to TWRP (at least on other devices).
If you are able to boot TWRP, restore the TWRP backup (if you made one) or put another ROM on the phone, and flash it.
I also have this kind of problem. After i update twrp by flashing it and restore a backup the sistem doesnt show. Stucks on nvidia logo. I tried even restore my recent backup but nothing also. Any idea ?

Heya peoples, I have a problem and am hoping for some help in a work around.
I am trying to root my J3 but my volume up button does not work. I have adb installed, and the correct drivers for my phone. I can use adb command to reboot to the bootloader and it brings me to the Odin "downloading" screen. I can then use the program to install TWRP so I can root. Everything goes fine up until this point. After TWRP is installed there is a single massive problem I am hoping there is a work around for. My volume up button does not work. I can only reboot to recover using adb once the phone boots up, and I read that if you let that happen it overwrites TWRP with the stock recovery (which is what happens when I do this). I read that you have to reboot directly from the downloading screen into recovery using Vol up and home and power. But I can't do that since my Vol up doesn't work. When I am at the download screen after installing TWRP none of the adb commands work so I can't reboot directly to recovery to access TWRP the first time. I hope this all makes since, and I hope someone has some advice because as far as I can tell I can't continue passed this point without a working volume up button.
A little more info in case it matters. When using adb command prompt I have to type ".\adb" instead of "adb" as the tutorials say. When I do ".\adb devices" my device shows up as connected. After rebooting to the bootloader using adb, typing ".\fastboot devices" shows nothing is attached, and any command I try to put in results in "waiting on devices". Checking the device management at this point does not show any unknown usb devices (one guide I read said if fastboot wasn't recognizing to check to update drivers if something was showing as unknown usb".
Basically hoping there is some way of booting directly to recovery from bootloader without having to use the vol up key combination so I can access TWRP for the first time. Any help at all is appreciated. I realize having a working volume button would take all the headache out of this but unfortunately fixing it is not an option at the moment.
Edit: I have also unlocked the bootloader using the Crom Services app from samsung, and have developer options and usb debugging enable.
Question: If I use an app to remap the buttons would that work? Wont be around a computer until tonight. Does remapping the buttons affect it at the level of being in bootloader (because if so I could just switch the up and down volume, use adb to reboot to bootloader then power/home/and remapped volume to reboot to recovery). But I feel like it wouldn't work if the app is not actually changig it but intercepting the button press and then changing it. I dunno.

Can this device even be rooted? Doesn't virgin lock their devices?
In any case if you flash twrp to the boot partition (rename it to boot.img) it'll boot directly to twrp then just use twrp to flash to the recovery partition.
Reflash the stock boot.img back to the boot partition.
