Fastboot doesn´t recognize my device - Android Q&A, Help & Troubleshooting

I can use adb commands no problem, but with the phone being in fastboot, fastboot commands like
Code:
fastboot devices
don´t show anything.
I want to unlock the bootloader but I am stuck with
Code:
waiting for device
after the
Code:
fastboot flashing unlock
command.
Why is it that every time I try to follow a tutorial, I do the exact same things and it doesn´t work for me?
Anyways, I installed all drivers from here and Device Manager shows an Android ADB Interface with a yellow triangle when I connect my phone in fastboot mode.

Can't unlock bootloader

Hello,
Since a few years, I have root, TWRP recovery and XPOSED framework on my device.
I thought It's time to go further and try out new ROM, but to do it I need to unlock a bootloader.
Unfortunately, when I'm entering a fastboot mode (notification LED is blue) the adb "fastboot devices" command does not show anything.
I'm working on Windows 10.
What am I doing wrong?
Is a twrp somehow blocking the access? Or maybe I can do it directly from TWRP recovery.
PS. Drivers are OK, because I'm entering the fast boot mode by "adb reboot bootloader" command.
Im fairly certain its driver on the pc side.
Try it on a different pc.
Adb needs different drivers from fastboot. You havent installes fastboot drivers from the driver package.

ZTE Z5031O refuses to go into bootloader mode

So i'm trying to get the bootloader unlocked so i can begin to mess with the device but it just doesn't want to go into the bootloader. It goes into recovery fine and i've tried going in there that way but it doesn't work. It just boots up android. Here's what i typed into my prompt.
adb devices
adb reboot bootloader
fastboot devices
adb reboot-bootloader
fastboot devices
adb reboot recovery
fastboot devices
Thank you in advance for trying to help

adb commands work but fastboot says "waiting for any device"?

I am on an older macbook pro running High Sierra. the phone I'm using is a Blu G5 running android 9. I have the developer options unlocked and oem unlocked and usb debugging checked. When i open my terminal i type cd and drag and drop the platform tools folder into the terminal window changing the directory to the folder containing the adb and fastboot files. I can use adb commands such as adb devices and get the serial number and it says devices. So far so good. Then i reboot the phone into the bootloader manually or using command adb reboot bootloader and the phone goes into fastboot mode. I know because it says it on top of the screen in white letters. Then i run into the problem fastboot commands don't work. If I type in fastboot devices nothing but a new command line shows up. When i type in any other command like fastboot device or fastboot oem unlock it says "waiting for any devices." I wait and wait but nothing happens. I have looked on the internet for a solution but all i find is that the driver may not deinstalled properly. I have tried manually installing fastboot driver and used sdk manager to install the fastboot driver and I have tried it using the terminal in android studio but no matter what when i try useing fastboot commands i get the "waiting for any device" message. Does any have a solution or could anyone recommend and forum for android development on MacOSX?

Seems the Fastboot driver is invalid.

I have literally tried like 10 different sdk tool downloads just platform tool download basically every thing i can find. By chance would you or anyone out there have a working driver for MacOSX 10.13.6? or link a guide that can help me figure this out. I have made a little progress with a forum on xda about fastboot on macs but i still just keep getting the waiting for any device message.
@DimDreams
May also be that the Fastboot Android mode is not available on the phone in question.
I've had similar issues before and noticed that fastboot mode works better via USB 2.0 than USB 3.0. Maybe check which port you're using and switch. ADB seems to work well either way, however. Hope that helped.
I just had this problem as well and I found this, what worked for me is first boot your phone into bootloader mode with
Code:
adb reboot bootloader
. While in the bootloader fastboot worked for me. Hope this helps someone!

Fastboot Not Working - G90 Pro

Hey all, I just got a G90 Pro that I want to put a ROM on, but something is up with the fastboot. I have the drivers installed according to what I found online, but when I go to fastboot there is no response from the cmd inputs. Nothing even shows up when I check fastboot devices. Has anyone had luck with these phones? I can't even unlock the bootloader!

I have done this, but did it again just to be sure, and device manager recognizes the G90 Pro under USB devices, and ADB finds it, but when I do the 'adb reboot bootloader' the fastboot mode text is on the bottom, yet fastboot commands don't do anything, not even 'fastboot devices'.
Edit: Fastboot devices is recognized in fastbootd, but not regular fastboot, yet the other commands don't work.
In your case fastboot is located in Android's user-space, hence you run this command sequence
Code:
adb devices
adb reboot fastboot
fastboot reboot fastboot
fastboot <YOUR-COMMAND-HERE>
fastboot reboot

Fastboot reboot fastboot just brings up the fastboot command list. Assuming it's expecting me to try reboot bootloader.
That's really weird because your phone is running Android 10.
My info in settings definitely confirms that. Nothing seems to be working as expected though.

Is there any other possible solution? I still can't get fastboot commands to work after rebooting to fastboot mode from fastbootd.
