[Q] [HELP] Unrecognized device in bootloader

Hello.
I'm trying to run the "fastboot" commands on my One but I don't. I'm S-ON and full stock. When I'm in the bootloader, my PC (Windows 8.1) brand me "USB Device Not Recognized". So when I run the command "fastboot oem getvar cid", it strikes me "Waiting for devices". But when the phone is started, it is recognized by the PC. Moreover it is with the command "adb reboot bootloader" I went into the bootloader.
In summary, when the phone is started, it is recognized by the PC (the driver has been properly installed with Htc Sync Manager). But when the phone is in bootloader mode, it is not recognized by the PC and when I go to the device manager it there's a yellow triangle on the pilot "My Htc".
I need help because I have absolutely run the "fastboot" commands, thanks.

I'm in a boot loop, ADB not working

Hello everyone,
Sorry I'm kind of a noob (obviously since I messed up my phone!). I unlocked my bootloader, installed TWRP, and rooted my phone. Stupidly, I flashed a stock 4.4 rom without doing S-OFF and am in a boot loop now. I was going to flash another ROM but can't get one on my phone. I tried to use TWRP to mount my SD card but, it couldn't mount my SD card. When I tried ADB it says no devices found. I've updated HTC Sync manager and the Android SDK manager but it still hasn't worked! Can you guys give me some help!?

What OS do you have on your computer?when you go to TWRP on your phone and type Adb devices in a command prompt does it no devices found?

Ok I feel a bit stupid... so i noticed on the device manager that the phone wasn't "installed properly". Updating automatically didn't work so I did a manual update and seemed to work. I installed Android Revolution HD 31.6 but now I'm stuck on the htc one boot screen.
I'm on Windows 8.1 and it said "device not found" previously

could you post the output of fastboot getvar all (without IMEI/sn) when in bootloader/fastboot usb mode plz? Also are you using twrp 2.6.3.3?

Can you do a factory reset in twrp and try again?

I reinstalled the ROM and everything is working now! Can't believe I spent 4hrs on this and then once I post a thread I figure it out! Thanks for the help though!

I can NOT get ADB to recognize this phone in fastboot mode.

Please for the love of god help me. I've tried everything.
I have a developer edition. I have the newest drivers, the newest phone updates. Everything. It is recognized by ADB when I'm on the home screen, but when I am in fastboot mode itself it will not recognize the device. I can't unlock the BL because of this. It's VERY frustrating and I'm about 12 hours from selling this device and buying an HTC M8.
I have Windows 7 64 bit. I'm on the newest moto drivers, the newest FW for the X. I've uninstalled and re-installed and restarted my machine countless times. With no luck. With the drivers installed I booted the phone into fastboot mode, pulled up a command prompt where ADB was installed, ran adb devices and nothing. Over and over again. Please help me. I really want to keep this phone.

Navigate to where fastboot.exe is installed, and run "fastboot devices".
And make sure phone is in bootloader mode.
Does it list serial number?

I ran into the same issue last night, I just got a moto x DE for my wife, and a new laptop since last March when I unlocked my moto x DE. "adb devices" returned nothing, and I had a fresh install of the SDK and the moto drivers. Both old and new laptop on Win 7 64-bit. I googled trying to find a solution, but didn't find anything that worked. Grabbed my old laptop, hooked up to it, and it worked fine.
One suggestion I saw and didn't try was to remove/reload the moto drivers. Since I got it working and got her phone unlocked with my old laptop, I didn't pursue further.

Adb devices wont work when the phone is in Booloader/fastboot mode.
Make sure you have the latest Moto drivers from here -> https://motorola-global-portal.custhelp.com/app/answers/detail/a_id/88481
Follow this -> http://mark.cdmaforums.com/ADB.htm To install The Android SDK, PlatformTools, and mFastboot, and add platform tools to the Path.
once that is done.. type fasboot devices and see if you get anything. If no, look at Device Manager and make sure there are no ! or such in there.

This is what worked for me. Posting here for posterity and potential helpfulness.

Even that wouldn't help him if he was trying to use adb while in the bootloader.

Thanks for clarifying. I only end up dealing with rooting something once a year or so and always forget the "ins-outs-and-what-have-yous". Once I was reminded of fastboot vs. adb all was well!

Droid Turbo - Mofo connects and flashes but fastboot won't...

I am not new to flashing phones, but I cannot figure this out. I can run Mofo and Mofoverify, but I cannot run a fastboot commands like "fastboot flash logo logo.bin". All I get is waiting for device. " Adb devices" and "fastboot devices" both return an empty list in there respective modes. Now I have tried several similar but not the same fixes from many Google and XDA searches. I have tried all sort of driver solutions, USB cables, toggleing of settings in my phone and such. I have used Mofo without issue and still can, but fastboot won't let me flash the setup files for Lollipop and I want me some sweetness! I have a newer Windows 8.1 machine and the XT1254. Lastly, this is my first Q&A thread post, so please be gentle. Thank you ahead of time, because this is XDA, and it can solve anything!

Any way you could try it on a Windows 7 machine?

Where did you get your fastboot files? If mofo detects it then your fastboot files are jacked up
Go here: http://dl.google.com/android/android-sdk_r24.3.3-windows.zip
Once you extract it, run SDK Manager, Select to install Android SDK Tools, Platform-Tools.
Once that's done, go to \android-sdk-windows\platform-tools. Hold shift, right click and Open Command Prompt. Then fastboot will work
O

Here's an easy way to install Fastboot/ADB.
Once that is installed you'll have to change your commands to fit the file path of the fastboot files.
For example:
Code:
fastboot flash logo C:\Users\OP\Desktop\logo.bin

This minimal version of fastboot is a lot smaller and worked for me.

I have used minimal Adb/fastboot. I don't know if it helps, but when in Android, even after revoking USB debugging authorizations, I never get asked on my phone to re-authorize my pc. As for a Windows 7 machine, I could downgrade my laptop, but I wanted that to be a last resort. 
 @savage- sorry for posting this on ComputerFreaks thread, but it was his image I am trying to install and figured someone doing the same as me may have had same issue, but I'm sorry.

A windows 7 machine is unnecessary. I used windows 8.1 pro x64 to perform the whole upgrade process without a hitch. If mofo functions correctly, that means the fastboot drivers are installed correctly. If you start up minimal adb/fastboot, plug in your phone while it's in fastboot mode and type "fastboot devices," what do you get?
EDIT: Duh. You already said that it says returns nothing. Well in that case there has to be some sort of problem with the USB connection or the minimal adb/fastboot installation. Maybe try running the minimal adb/fastboot shortcut as administrator. I don't remember having to do that on mine, but who knows?

St33ve- see OP, nothing listed for adb or fastboot devices commands in their respective modes.

Have you tried a different USB cable?

Yes, about 7 different ones. 4 that I am sure have worked before, and no physical damage to them.

You said Mofo is able to see your device though, so that's kind of throwing me through a loop. You could try a fresh install of the Minimal ADB, and double check your drivers?

That's a sign of drivers not being installed!
Try opening up device manager n see if the driver is not installed.... If u see a device with an exclamatory mark n "quark" somewhere in it... The drivers aren't installed...

When the phone is in fastboot mode, the phone is listed as quark fastboot, but no exclamation mark. I reflashed computerfreaks image (KK) without an issue, but still isn't recognized in fastboot or Adb. I really want to flash me some Lollipop! I have crack flashed with every phone I own. I'm going thru withdrawals here LOL.

i am having the exact same issues. I've reinstalled drivers, switched usb cords and have had no success.

I'm not certain what actual fixed mine because I tried so many things but I got mine to recognize my phone. I think what did it was revoking the USB debugging authorizations and deleting the adb files on my computer under username/.Android. Then reauthorizing my phone. That and I believe I may have had duplicate drivers interfering with each other. Hope this helps

Hallelujah, I have lollipop!!!
I do not know exactly what the issue was but after factory resetting windows 8.1, and manually loading each driver for adb and fastboot, it works (again). I wish there was a Thank All Button. THANKS ALL!!!

Fastboot won't run in Windows 10 Anniversary 64 bit

I have used adb and fastboot for a long time, and this is the first time I've had a problem. I updated to the August security update on the first with no problem, and my computer updated to Windows 10 Anniversary 64 bit on the second. I can do "adb reboot bootloader" and it works, but any fastboot command, even "fastboot devices" does nothing.
Windows Device Manager shows an exclamation mark for "Fastboot Shamu S". I have looked for hidden devices and uninstalled the driver. I tried to update the driver but Windows can't find one.
The adb and fastboot drivers I have been using are from December of last year, so I installed these: http://www.teamandroid.com/2016/06/15/install-fastboot-adb-google-usb-drivers-windows/ but still can't get fastboot working.
Has anyone run into this and can suggest a solution?

Same configuration here - Windows 10 Anniversary 64 bit ,shamu, old fastboot files and drivers from Google. Everything is fine.
Try to download official drivers.

The W10 anniversary update doesn't accept drivers that aren't certified by Microsoft.
When there are no certified fastboot drivers you may thank Microsoft.

If it's a driver issue, uninstall then follow this http://www.howtogeek.com/167723/how...8.1-so-that-you-can-install-unsigned-drivers/
Then reinstall after disabling the driver signature verification

Thanks to all! Installing the driver from "latest_usb_driver_windows.zip" in your link did the trick!

Works fine for me.

Not sure if exact to your issue but I'm using a moto g play (2021) and windows 10. Now as long as I don't boot android into recovery mode, the phone is available within file explorer as well as command line. Once I boot into recovery adb commands useless. Unseen. I've reinstalled every driver... It just won't let me fastboot

Now, this thread is for the Nexus 6 phone. If your problem is specific to the Moto G Play, it is unlikely that anyone here is able to answer.
But generally, fastboot works when the phone is in bootloader mode, not in recovery. However, not all phones have a fastboot-compatible bootloader.
If you have installed an advanced recovery like TWRP, you should be able to use adb. But probably not with the default recovery.
