Google doesn't know, so maybe the experts here can help.
I'm trying to unlock the bootloader of my Nexus S 4G.
I installed drivers via PDAnet. USB Debugging is on. Windows detects the device, both when its on in normal mode, and in Fastboot mode. ADB detects the phone when on.
Fastboot won't detect it when in Fastboot mode, though!
ADB won't detect it in Fastboot, either. (But maybe that's normal.)
Why doesn't fastboot see it?
I'm running Win7 x64, if that helps.
Thanks in advance.

Nothing shows up. No errors. No devices.
Are you in bootloader mode when you're doing fastboot commands?

I'm in "fastboot mode", I think that's what its called.
I get there by holding Vol Up + Power when I turn it on.

If you have the USB Driver from the SDK installed edit android_winusb.inf and add:
;Nexus S
%CompositeAdbInterface% = USB_Install, USB\VID_18D1&PID_4E20&REV_0100
Go into device manager and tell it to update the driver, hit pick from list, all and have disk. Pick the INF and let it install.

Hi, I had the same problem, I fixed it by giving the command prompt root permissions (I'm using Linux). On Windows, make sure the command prompt is running AS THE ADMINISTRATOR

Hi,
Could some one point me to the correct usb drivers for the oneplus 7. I have oem unlocking enabled.
The device responds to the adb commands, but is not recognized in fastboot mode.
In the device manager there is a yellow triangle when in fastboot mode, so i suppose its a driver issue.
tnx
Solved
After connecting my oneplus 3 to my laptop windows 10 installed the correct drivers and after a reboot the oneplus 7 was also recognized in fastboot mode.

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

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.
