i think is the driver, because fastboot use another driver. try in device manager to search for a right driver

Can't enter fastboot mode, plz help.

im trying to enter fastboot from bootloader but every time i select it, it just reloads the bootloader. everything else works fine.

the bootloader IS fastboot mode.

Well when I run fastboot protocol nothing happens

Get into Bootloader. (I use ADB command: ADB Reboot Bootloader)
Use the volume down button to select "Fastboot Protocol."
It is deceptive as the screen on your Shield won't change.
Use your fastboot commands now. See if that works.

You need to make sure your fastboot and adb drivers are installed and recognized.
Also need fastboot on your pc of course. Good luck.
Once again, the bootloader is fastboot on your tablet, if you are on that screen then you can use fastboot if the above conditions are met.

Same symptom here.
When Android is loaded, Win10 finds it as both MTP and USB debugging device. adb is reporting back. All well.
However, when shield is in fastboot mode, fastboot finds nothing.
In my case reason was driver:
when connected in fastboot mode, win10 wants to install an
Android Device -Android Bootloader Interface
=> you see this in device manager
To satisfy Win10, download NVIDIA USB driver from here
https://developer.nvidia.com/shield-open-source
hence point the driver install in Win10 device manager to the driver download/extract location
Reconnect your shield.
In my case this worked.
Hope this helps

Thank you, worked very well for me.

fastboot cannot recognize device but adb can

usb debugging is enabled on device. running latest version of adb, fastboot. Have tried on both mac and win10 but same issue on both.

bootloader-fastboot mode is the only time fastboot commands will work. I know you tried this "also". But I feel you are wasting your time trying to run fastboot when phone is booted (instead of focusing on the situation where fastboot should actually be working). adb and fastboot will not work at the same time by definition. Also, debugging does not need to be enabled for fastboot (only for adb).

Try a different cable, different USB port. Fastboot can be finicky sometimes. You can also go to Windows Device Manager, find the device, and see if you can manually select the drivers. There is a generic Android device driver that sometimes gets fastboot to work properly on some of my past devices. This is on Windows 7, haven't done this on WIn 10 yet, so not sure if it is exactly the same.

What's you gotta do is look up how to disable signature verification in Windows 10. Then once you done that stuff put your device in fastboot mode then on the window 10 PC open of device drivers find Android phone then bootloader update driver. There will be 2 choices for updating pick the on device one. Should do you right.
I had to do this after flashing the T-Mobile version to my international version with the msmtool and it locked my bootloader for me

Since adb is working, do an adb reboot bootloader and it'll then boot into fastboot. If you can't get a return on fastboot devices at this point, it could be you haven't oem unlocked your phone yet.

I ran adb reboot bootloader from pc to boot phone into fastboot.
In the bootloader it states device state is unlocked
However fastboot devices ran from pc still shows no device.

This worked for me as well. Just to make it clear, rephrasing his reply. After disabling signature verification on windows 10, connect your phone in fastboot mode & open Device Manager on Windows & look for Other > Android device.If it is found, This means Windows 10 is not having proper drivers to recognize fastboot device. Now install "OnePlus_USB_Drivers_Setup.exe" & it will show pop up for installing driver & after accepting(this is blocked due to signature verification in normal situation), Android device will be recognized in fastboot mode.

ugh. I've tried all of these suggestions and still can't get the device listed in adb while in fastboot.
I even used the TOOL ALL IN ONE without success. Funny thing is, that program recognizes my phone being in fastboot and has it listed. But if I try to flash a recovery from there, it opens a command window and ultimately says there was an error in connecting to the device.
Any help is appreciated.

I have a similar problem. I tried to disable the signature. Installed a new Redmi Note 7 driver. The phone is recognized as an Android phone in the device manager. In Orangefox recovery it is recognized with ADB command. In fastboot it is not recognized. In Orangefox I can't format data. So my ROM is not booting up. So I want to flash fastboot ROM with Fastboot but in Fastboot device is not even recognized.

Sorry on the late reply. Pretty sure you can only do fastboot boot boot(recovery).img or\and boot_a or boot_b. Wont let you fastboot flash boot.img.

Thank you so much!

I also had same issue. my redmi note 6 pro and asus zenfone max pro m1 can be detected in adb but not in fastboot. tried everything. changing driver/disble signature verification. also tried virtual box ubuntu/window 7. but not succeeded. It is actually an issue with usb 3. so I bought usb 2 hub. now everything works fine.

Thank you Thank you Thank you Thank you Thank you Thank you...I have been fooling with this all day

Hi, I already solved this issue (but this only works for xiaomi phone (Redmi Note 7 to be specified), for other brands I think need to download your devices flasher/driver tool)
For Xiaomi user only
1. Download Mi Unlock Tool (https://mi-globe.com/download-xiaomi-mi-unlock-tool-all-versions/) (Version 4.5.813.51)
2. Extract the files anywhere you like
3. Run MiUsbDriver.exe to install the driver
4. Try fastboot devices command
I hope this helps you guys. The Mi Unlock Tool also useful to unlock device locked bootloader.
For other devices maybe can follow this tutorial

Installing GrapheneOS onto Google Pixel 3 - Fastboot Unlock <waiting for device>

Hi guys,
Looking for a genuis here...I've spent the last few days trying to work this puzzle out:
Installing GrapheneOS onto Pixel 3 phone using Windows 10, using command line tools only. Android Studio is not installed on the PC.
Here's what I've done so far...downloaded:
The Pixel image - GrapheneOS stable channel for Pixel 3
ADB & fastboot
First we downloaded fastboot (ADB, Android SDK platform-tools for Windows): https://developer.android.com/studio/releases/platform-tools - had an issue with the fastboot flashing unlock command...it doesnt unlock the device, instead says <waiting for any device>
Then we deleted the SDK platform tool and installed Minimal ADB & Fastboot and the same darn issue happened - the fastboot flashing unlock command doesnt unlock the device... command prompt says <waiting for any device>
The device is carrier unlocked, OEM unlocking enabled, USB debugging enabled, File transfer (MTP) mode on.
The following commands work with the SDK platform-tools & minimal ADB & Fastboot: adb devices, adb reboot bootloader
The block is the command: fastboot flashing unlock as we keep getting <waiting for device>.
Tried to fix this myself, here's what has been tried so far (not necessarily in this order):
Checked Fastboot version... fastboot --version works for both downloads so it's recognising it! Wahoo.
Used command prompt & powershell - when it gets to the fastboot flashing unlock command the response is always <waiting for device>
Checked the PATH (in control panel / advanced setting) and made sure environmental variable goes to the right folder
Downloaded Google USB Driver - nothing changed, we already had up-to-date drivers
Tried to change the fastboot script, click to open the fastboot file, when I click "open" the command prompt pops up, red error message flashes then the command prompt window closes in the blink of an eye. I then turned off Windows secuirty setting for app, same thing still happens.
Tried all USB ports with USB-C cable - same error <waiting for device>
Tried all USB ports with anotehr USB-C cable - same error <waiting for device>
Please help!

The ‘waiting for device’ is generated by Fastboot on PC when it can’t detect your device / can't communicate with phone's bootloader.
If the matching "Android USB Driver" got installed on PC, if latest Fastboot driver got installed on PC, too, and if you have rebooted PC afterwards at least once, then Fastboot should work if USB-cable that came with phone is used.
Hint: Try a different USB port on PC.

Thansk so much for your reply! I have a few questions though...
I think it can communicate with the device as "adb reboot bootloader" turn the phone off and puts it into fastboot mode?
What is a macthing Android USB Driver? In Device Manager the pixel 3 appears under "portable devices" so I assume that means we have a driver for the device?
Thanks again!

Whether phone got booted into fastboot / bootloader mode via command
Code:
adb reboot bootloader
or not can only get verified by command
Code:
fastboot devices
Your Google Pixel device is based on Qualcomm SDM845 Snapdragon 845 chipset, hence the "Android USB Driver" I mentioned must match this chipset.

Thanks so much, I think we are getting closer to success!
Qualcomm USB driver downloaded and successfully installed.
Update since the Qualcomm USB driver download:
adb reboot bootloader command works - phone goes into fastboot mode
fastboot devices - no response (new command line)
fastboot - -version shows version and installation
fastboot flashing unlock response is still <waiting for any device>
Used command adb shell getprop ro.boot.cid and response is 00000000
Response should be 11111111 if it's a Google phone...is this my issue? Or does it help explain why fastboot isn't working?

Fastboot operates on device's bootloader only if unlocking bootloader isn't denied. Makes sense,, doesn't it?
Me and all my friends always test this by running
Code:
adb devices
adb shell "getprop ro.oem_unlock_supported" <- on some devices: adb shell "getprop sys.oem_unlock_allowed"
If returned value is 1 - or true, then it's supported otherwise it's not.

Hi,
I don't know if it will help but try this.
PROBLEM
I tried all manner of ADB drivers and fastboot drivers for the last 4 hours just so that I am able to oem unlock this OnePlus device.
I have all OnePlus drivers installed. I have the ADB drivers installed from here. With all these I was able to run adb commands on the phone when it was on including commanding the phone to enter into EDL mode, commanding the phone to reboot into bootloader (fastboot mode). However in once in Fastboot mode, I could not communicate with phone and all I got was "waiting for device".
SOLUTION THAT WORKED FOR ME
It could be a computer brand model. Turns out the problem was not Windows. The problem was not Oneplus. The problem was my Lenovo Thinkpad which apparently requires its own Lenovo USB drivers.
If at all you're on Lenovo machine and you're stuck on "waiting for device" in Fastboot mode despite trying everything, then try installing Lenovo USB Drivers. I would recommend installing the generic ADB drivers first from here. Then installing the Lenovo drivers that are specific to you machine from here. Mine is Thinkpad.
I really hope this helps if not you, then someone else just about to pull their hair out.

ADB problem only in fastboot

Hello, i have a really weird problem. When the phone is power up and working i can adb devices and see in the list my phone,. But when im in fastboot adb devices show empty. The phone is recognized in my device list with the drivers in fastboot mode.
I have installed a lot of drivers
i have tried in windows 10 and windows 7
thanks in advance.

When you're in fastboot mode you need to use the fastboot command, not ADB...
Try fastboot devices.
