Hi,
I realize a lot of people might have the same problem as I have, but haven't found the answer after searching for many hours. So here's my problem:
windows vista x64
installed android SDK and all related drivers
GN is recognized with correct driver in both fastboot mode and regular "on" mode.
GN is recognized as a device in regular on-mode with 'adb devices'
GN is recognized as a device in fastboot mode with 'fastboot-windows devices'
HOWEVER, when GN is put into fastboot mode, NO devices are found with 'adb devices' even though the icon for 'safely removing hardware' pops up with 'Android ADB Interface', which means the driver is correctly installed.
Someone please help explain why the device is not recognized by 'adb devices' command under fastboot mode even though it's recognized by the computer!
Summary:
GN is found with 'adb devices' for normal boot, but GN is not found under 'adb devices' for fastboot mode. I have reinstalled the android ADB driver, but still the same problem.
I am stressed out! Please help me
I have noticed exactly what you are talking about however what I have found is that it doesn't seem to need to be able to respond to the adb devices command. I was still able to unlock,root and flash multiple different boot.img and radio.img files through fastboot without the computer returning the device while in fastboot. Hope this helps.

P.S. while you are in fastboot mode it seems you may be looking for something different than standard adb commands. Fastboot is primarily used in this situation so a command for you will typically look something like this"
fastboot-windows flash boot boot.img
or
fastboot-windows flash radio radio.img (the radio.img and boot.img files used in these examples you would want located in the same folder as fastboot-windows)
if you want to try the software out without flashing it "permanently" try:
fastboot-windows radio radio.img (just forget the flash portion)
for unlocking the bootloader the command will look something like this:
fastboot-windows oem unlock
ADB isn't used in fastboot mode, fastboot.exe is.
ADB is for when the phone is running Android or recovery only.
Phone doesn't recognize ADB in fastboot
Phone doesn't recognize ADB in fastboot - have used every conceivable method - downloaded Samsung drivers. Downloaded PDANet. Uninstalled Samsung and tried Naked Samsung. I got the phone unlocked. But I CANNOT get the PC 64 to recognize ADB when I am in fastboot. HELPPPPPPP. I've been working on this for TWO DAYS, and it is RUINING my Christmas holiday.
Have you tried the driver installation/troubleshooting section of this post?
Unfortunately, yes. I tried the Samsung drivers. Then I tried the PDANet. I also tried the Samsung naked drivers. I was sure that MSKIPS toolkit was going to work, but when I typed in "2" for rooting, NOTHING happened. I'm at my wits end.

Of course it doesn't.
AS STATED MULTIPLE TIMES IN THIS THREAD, YOU MUST USE FASTBOOT.EXE.
Please, read thread then reply.
When phone is turned ON - use adb
When in FASTBOOT mode - use (surprise surprise) fastboot
When phone is turned on or in recovery - use adb (check it with "adb devices" ,without " in cmd)
When in FASTBOOT mode - use fastboot (check it with "fastboot devices" ,without " in cmd)
In order to work fastboot you must have the fastboot.exe preferably in the same folder with adb
Try this
I tried installing PDAnet but no Joy.. but went to device manager and selected adb drivers and samsung from the list and that did the trick...
Hello,
I have problem with my phone and adb, I have installed all driver for my htc, adb, fastboot,.. but when I try to check for connected devices in adb via adb devices command the list is empty even if windows recognize the device. I have tried it in Ubuntu, but the situation is same.
I don't know whats wrong, because it works for my Gnex and GTab.
Did you enable USB debugging on the phone
Sent from my HTC Desire using xda app-developers app
that was the first thing i made

...and it is perfectly OK.
The adb tool on your PC needs a adb daemon running on your device: this happens when the Android system is running (or a Recovery with adb daemon). When you are in fastboot mode the Android system has not really started loading yet, so there is no adb daemon to talk to your adb tool on PC -- hence your phone is 'not seen' by adb.
But it is seen by fastboot tool (another part of Android SDK tools) at this stage. So in fastboot mode you can flash images and do other stuff: just not with adb tool, but fastboot tool.
Well thx for eplaining my bad i thought that it will respond to adb devices like my other devices
PLS Close this thread

Hi guys,
i recently received my nexus 5x and would like to root it like my old nexus 5.
The drivers are installed, filetransfer from and to phone/pc is working, adb see's the device. PC is windows 7.
But when my 5x is in fastboot mode the fastboot devices command shows no results and any other command like fastboot oem unlock get stuck at < waiting for device >.
Am i missing something? Do you have any idea?
Thanks for your help!
edit: the device manager shows the 5x as unknown device when in fastboot mode
Download the latest version of fastboot.exe
Yep, I was having fastboot issues as well but it turns out that there are updated fastboot binaries for Android 6.0 that you need to get.
Hy
I had an unlocked bootloader phone. Yesterday I flashed the new Android 6, Europe version from the Huawei blog forum, no beta, on my Huawei GX8. I used the method, dload on SD card, Phone off an the press Volume down+volume up+Power button.The flashing was normaly.
Now the phone starts normaly but I can´t start fastboot. When the phone is off and i press Vol down + Power the phone start the android system and the Huawei logo is coming not the fastboot Modus. I can see my phone and the order under Windows but i can not control my phone with the fastboot command. (example: fastboot device. the answere ist searching devices, but it comes no resolution) I loaded the last version of Fastboot, but the problem is the same.
Please can you help me. What can i do? Many thanks for your help!

And when you use adb to reboot to bootloader, what happen? Do you have "Minimal adb and fastboot tool" installed?

Sorry for my question, what´s the differents about adb and fastboot tool? I have install the last version of minimal adb and the fastboot tool, also the Windows driver for the phone. Debugging is on. I try to connect my phone about the fastboot terminal. When i try to set the phone into the bootloader mod with the fastboot terminal and the equivalent command, fastboot say´s "searching phone". My phone does not react.

So, you connect your phone, open minimal adb and fastboot too, run "adb devices", you see device id? If yes, run "adb reboot bootloader" . Phone shoult reboot to fastboot mode. Then run "fastboot devices" to see if it is connected properely.
i did it, like you described, but i see not my device id. Only the note "seach device"
Is it possible that TWRP is defect on my device? Is TWRP necessary for fastboot or only for root?

No, you should be able to use adb and fastboot with stock recovery.
After first adb command you shoult approve authorization on your phone.
Here is screenshot from minimal adb...
Phone must be in MTP mode.
And here is phone in fastboot
Many thanks for your help, now I m in my bootloader.
2 problems i had.
1. My daemon was not started correctly, i have not seen my device.
2. I used the wrong command. I started with fastboot, not with the command adb device. I tap „fastboot reboot-bootloader“,but the correct command is “adb reboot-bootlader“
Now i have seen my phone is unlocked, i hope i can root my android 6.

Just reboot to fastboot and flash surdu-petru version of TWRP recovery 3.0.2 with command "fastboot flash recovery xxxxx.img". And than reboot to recovery and flash supersu zip.
