[Q] adb driver not working

I've been trying to access my GNex in fastboot mode, but my computer doesn't recognize it when it is in fastboot. I have tried to install the samsung adb drivers, but not matter what I try, I cannot get my computer to connect using the adb when the device is in fastboot. Any help would be appreciated.
I am running window 7 x64 btw.
EDIT: When my device is connected and I am not in fastboot mode, i am getting the "SAMSUNG Android ADB Interface" listed in device manager. So I am assuming I have the driver installed correctly.
EDIT 2: When I use
Code:
adb reboot bootloader
the device goes from recognized to Android 1.0, and if I try to
Code:
fastboot oem unlock
I get
Code:
<waiting for device>

After 'adb reboot bootloader', and device being recognized as "Android 1.0", just manually update the driver: its the same driver that you used for adb. Windows is dumb.
Use search or browse the forums, read the stickies, this has been covered over and over again.

If all else fails get mskips galaxy nexus toolkit v10.x, see xda thread or google skipsoft, and let it sort out drivers and adb, it has easy options and a good help section, should get the job done.
Btw if you are having driver issues you should try the driver download pack from samsung official website's manuals and downloads, its a tad under 30mb, run it then reboot computer then plug in gnex and any missing drivers should auto install, be patient, windows is a retard so it may take a coupla minutes

This worked for me:
rootzwiki -> Google/Nexus Devices -> Galaxy Nexus -> "Galaxy Nexus Root Procedure - (broken) ADB Method Dont USE" -> page 3, second to last post on the page (by litso):
"EDIT: Scratch that, was able to use the PDANet drivers. Install PDA Net, reboot into bootloader, open device manager, manually select the directory "C:\Program Files (x86)\PdaNet for Android\usbwin". Fastboot will then recognize the device and allow you to unlock."
I can't post a link because I am a 'new user' due to low number of posts, but that is the path to your solution. I literally just went through this yesterday.
It's basically what bk201doesntexist said in the above post. I used the pdanet driver, but I'm sure the normal Samsung driver should work.

Not able to detect phone in fastboot

Tried on windows 10 and 7:
Phone is detected by ADB and commands work no problem. Boot in to fastboot (download mode) and the device isn't found when using "fastboot devices". The phone appeared in device manager with the yellow triangle but I manually updated the driver to "Android Bootloader Interface" however, I still get nothing. Am I missing something?
Thank you.

Mine never has shown in fastboot, if it shows up in device manager it should work fine. To test just try fastboot reboot.

If you corrected the issue with the driver,the problem may be with the versions of Fastboot you are using. You can download the latest Fastboot and ADB files from Google directly if you search for them it should be the first or second link.

You need google usb drivers

I have the latest google usb and platform tools on a windows 7 &10 systems using different usb ports along with multiple cables and I can not detect the phone, but I can flash.

[HELP] MI a2 lite Fastboot Exits aAutomatically

I have a mi a2 lite and i want to unlock its bootloader, i have alrready enabled oem unlocking on developer options, when i boot my device in fastboot and connect to computer, command window says waiting for device and after 15-20 seconds of connecting my device to my pc, fastboot mode automatically exits and shows charging animation. Please anyone can help?
My device is in andoid pie (stable).

Check if you have installed drivers and run "fastboot devices" to see if device is recognised.

Agree something with your PC.
Phone will automatically exit fastboot if no connection in timely manner.
Check drivers are installed, reboot your PC.
Also be sure USB debugging is on in Dev option and trust PC.
For me, I generally boot Android normal. Then plug into PC and from command line, "adb reboot bootloader". That should verify adb, If that doesn't work, your PC not talking to device.

I reinstalled the drivers and the command "adb reboot bootloader" works for me that means it boots to fastboot mode but when in fastboot mode, when i enter a command "fastboot devices" it does nothing and when i enter command "fastboot oem unlock" it again says waiting for any device.
i have attached a screenshot of it.

I've tried restarting my pc as well as my phone and after 5-6 attempts it is now unlocked.
Thanks guys for supporting and giving response to my post
Love ya'll

The solution for fastboot disconnecting after a few seconds are the windows drivers. There are different drivers for our phone, normal, bootloader and fastboot. Windows loads these drivers depending in which state the phone is.
If you still didn't find the correct drivers, you should try installing MiFlash, as it contains all the needed drivers for our phone
If you like to try the Linux way, there's a distro called FWUL linux here on XDA

Yeah, just go to windows drivers, click update device driver, browse my computer, let me pick, choose android > next > and choose another version or try whatever you feel is appropriate

Can't unlock bootloader - fastboot issue

Hello,
I am trying to unlock my bootloader but I my computer (Windows 10) does not recognize fastboot.
When I connect to fastboot (holding volume up button + connecting my phone by USB when it's off, or using the adb reboot fastboot command), the computer does not recognize the phone. I then tried installing drivers (both from Google and Sony) by going into device manager but Windows just doesn't install the drivers.
I then saw this on Sony's website:
Fastboot driver - Sony Developer World
developer.sony.com
So I download the file and pasted it instead of the same file (android_winusb.inf) in the Google driver folder, and it somewhat worked, but Windows said something like unable to find drivers for ADB.
I also tried to install in Windows test mode but to no avail.
No matter what I tried, entering the command fastboot devices in fastboot mode does not give me any output (not even "waiting for device").
What am I doing wrong?
Thank you!

Did you already disable driver signing? Pretty sure you have to do that with Win 10. I would disable driver signing, and then use " 15 second adb installer" from XDA. Always has worked for me...

Fastboot issue Moto G8

Hey there,
so fastboot does not recognize my phone in bootloader mode.
USB Debugging is enabled.
- ADB Commands work
- Fastbootd Mode and Fastbootd Commands work (adb reboot fastboot)
However in Bootloader Mode it just does not show up. Either under Windows or Linux (No Device Manager, No LSUSB, Nothing)
Drivers are Installed.
- I have an AMD Processor and i am aware of the issues. I tried the USB controller fix.bat without any changes.
- I have disabled Driver Signature in Windows 10, still nothing
Please help :/
