Trying to unlock the bootloader

I get through all the steps, adb setup recognizes my device is connected. When i try to unlock the bootloader <fastboot oem unlock> command line locks up at <waiting for device>.
can someone advise?
Verizon if that matters

What happens when you type in "fastboot devices"

Nothing happens. Tried it both before and after typing in adb reboot bootloader

You sure your pc is detecting the phone when it is in fastboot mode? To me it seems like your computer isn't detecting the phone or the drivers didn't get installed properly.

answered my own question

I had the same issue. Assuming you're using Windows, you need to find where the latest Samsung drivers for the GN were copied to when you installed them (you have installed them, right?) The next time you plug in your phone, it will probably ask you to setup a new device. Tell it you will install the drivers from a location you choose, navigate to the folder where the drivers are, let it install them, restart if it asks, and then try the process over.
FWIW, I used the directions and links from this tutorial and eventually got it working. They include alternate drivers here in case the one from samsung.com doesn't work.

im having the SAME PROBLEM AND HAVE TRIED TWO DIFFERENT COMPUTERS.TRING ADB METHOD

What's the ADB method? Why don't you just just hold the volume up, volume down and power to get into fastboot mode? When you plug it in, windows should see a new device that needs drivers. You need to make sure the drivers are installed before fastboot will work.

i am in fastboot "little android with chest opened". and i do have the driver installed but in fastboot windows thinks its a different device

Is it saying that it couldn't install the drivers for Android 1.0 or something like that? What step are you at? Which tutorial are you using?
Read the driver installation part of this tutorial.

Tips:
-We know that many of you are running into a “waiting for device” issue when apply the fastboot oem unlock command. This is a driver issue and one that a reader has a suggestion for:
1. Open device manager on your PC.
2. Right click on Android 1.0 with the yellow ! mark on it.
3. Choose update driver.
4. Choose browse my computer.
5. Choose Let me pick from a list.
6. Scroll down and find the Samsung driver with newest date. Should be the driver you downloaded above. (Possibly dated 11/25/2011 ).
7. It will give you a warning about installing the driver, just click yes.

[Q] Phone not being recognized by computer in bootloader?

So I've been trying to root/unlock my CDMA nexus and I'm having a very frustrating problem that's preventing me from doing it with any of the toolkits available OR the manual method. I have the android SDK installed, samsung's USB drivers, and everything else I've been told to get. I can detect my phone when it's connected (and USB debugging is on) using adb commands but ONLY when the phone is booted as normal. If I reboot into the bootloader, my computer no longer detects it, and I can no longer act upon it via adb. This, of course, is preventing me from getting anywhere on the unlocking/root front. Anyone have any ideas? I'm fresh out.

ADB doesn't work in boot loader/fastboot. Adb only works in recovery or when Android is fully running.
You need to use fastboot commands in bootloader/fastboot.
"Fastboot devices" to see if it's detected.

have you installed the hboot drivers?

As above, you have to use fastboot commands when the phone is in bootloader. Try "Fastboot devices" to see if your computer sees the phone.

Fastboot commands don't detect the phone either. Fastboot is installed, as I can get it via command prompt to show available commands and whatnot, it just does not detect a device to work on.

I am also having this exact problem when i try to install the new touch cwm beta that was just released. Its not detecting the device while in the bootloader, and when i try to fastboot flash recovery it just says <waiting for device> and does nothing.

I know this is a little late, but I figured I’d post here to help anyone else out that is having this problem. I was trying to update my Galaxy Nexus from 4.0.2 to 4.0.4 using fastboot when I ran into the problem you’re having. I did this from a Windows 7 machine, and the fix for me was as follows:
1. After booting into the bootloader and having your phone plugged into your computer, open Computer Management.
2. Under Device Manager, in Computer Management, you should see a listing for a device called “Android 1.0” and it’ll have the little yellow triangle with the exclamation point on it.
3. Right click on the Android 1.0 device and select “Update Driver Software…”
4. Click “Browse my computer for driver software”
5. Click “Let me pick from a list of device drivers on my computer”
6. If you installed the Samsung drivers for the phone, scroll down until you see a device listed as “SAMSUNG Android Phone”
7. Select it and click next
8. It should auto populate the driver information. Click next and it will install the device
9. Go back to your CMD prompt and fastboot devices should now list the phone.
Hope this helps!

Quicks man your the best!

Fastboot Issues

I have searched the net high and low for a answer to this question but nothing I have tried works.
I have used every adb and fastboot installer i could find, but nothing i do get fastboot working on my 5t. ADB is recognised and i can reboot to the bootloader from a command shell. But as soon as i type "fastboot devices" it shows nothing.
I have been into device manager and it shows issues with the fastboot driver, i have tried everything i can think of to fix this issue.
I would really love to root my 5t and and have never encountered this many issues on any of my previous devices.
Running a 64gb OP5T and Windows 10
Thank you for your help

I have now re-installed windows 10, re-installed all drivers and ADB and fastboot. ADB is still working but nothing from fastboot. It's recognised properly in device manager but nothing shows up when I type fastboot devices or fastboot OEM unlock. Any tips would be great.

check this link specially driver signature enforcement disable part, it may help

When you say "nothing shows up", what exactly is the response?
How are you getting into the bootloader? Use this from recovery or system:
Code:
adb reboot bootloader
Then proceed.

ADB is working fine. But as soon as I reboot to fastboot mode the phone doesn't respond. I can't work it out have tried everything.

It just says waiting for device or says nothing and brings up a new line. I'm guessing the fastboot driver is the problem. I have installed the Oneplus drives included with the phone. I've installed the universal ones, still nothing.
Is there an individual fastboot driver I could manually install through device manager?
Appreciate the help.

The issue is finally fixed! I went into device manager and changed the driver from a list of drivers on my pc to WINUSB and now its working

Same problem here pal, how did you change driver to winusb, seems I've got all the gear just no idea... By gear I mean files/drivers lol. Rooted so many devices I thought this would be easy, looking forward to getting it sorted. I love a custom rom

Cannot install USB drivers for Razer phone on Win10

Howdy,
I'm trying to get my phone unlocked and rooted. As the first step, of course, I'm trying to get the Google USB drivers to install, but I simply can't. I feel like I'm the only person having this issue, though because I cannot find a solution... The steps I'm following:
Downloaded the latest driver zip from Google
Open Device Manager
Expand Portable Devices
Right-click on the Phone entry (notice, that's the entry, "Phone". Not Razer.)
Choose Update Drivers
Browse my way to the drivers folder and click Next.
Windows then returns immediately "The best drivers for your device are already installed", and shows that it's an MTP USB Device.
I noticed that under USB devices, there's an ADB Interface device listed, and I get the same results when I try to update that, too (excepting it says it's an "ADB Interface" device, of course). I have tried uninstalling both devices to get the drivers to install, but no such. I've rebooted both phone and computer as well.
On the phone, USB Debugging is turned on, and USB mode is set to MTP file transfer.
Please help!

Figured it out...

In case anyone else is seeing the same issues, I wanted to put my resolution up: I'd been trying to install the drivers with the Razer booted. On a whim, I rebooted it into Download Mode using "adb reboot bootloader". Once there, I had an Android Device listed in Device Manager. I ran the driver update wizard, and installed the "USB ADB Interface" option from the choices presented. I was then able to run the OEM unlock command and received the confirmation prompt on the Razer. Yay!
Now, since it's been so long, I've got to re-back-up everything so I can actually do this thing. LOL

Here's the PDF from Razer's how to install a factory image over PC guide. It explains how to do it all

No fastboot!

Hi there,
I'm trying to install TWRP. But I can't do any fastboot command. ADB works. Device isn't recognized in system and with "fastboot devices" nothing shows up. :/
I've tryed many drivers but nothing works.
I'm using Win 10 x64. Does anyone have a suitable way to get it working?
Thanks!

This is a problem related to Windows 10 that uses the wrong driver.
Somewhere I have found a guide to manually choose the correct one, but at the moment I don't remember where... googling you will find instructions

Oh sorry.

Does someone have an idea?

This might come a year too late, but in case someone else runs into the same problem (like myself), you can solve it by installing the latest (signed) ADB drivers with this Tool, then rebooting the tablet to fastboot mode and run the tool again. This still doesn't install the correct fastboot drivers, but it should now be listed as "ADB Interface" -> "Unknown Device" in the device manager, and if you right click and choose "Update driver" -> "Browse my computer for driver software", you should see a driver called "Fastboot interface (Google USB ID)", that installs and works correctly for the Pixel C.

@Mambobuzzz
One option you have and it's been updated this month too, is you could try installing and using tiny adb & fastboot from here: https://forum.xda-developers.com/t/tool-windows-tiny-adb-fastboot-august-2021.3944288/
I can't stand Windows for a few reasons! Make a live USB and try a Linux distro! You will never have this problem again and I guarantee you won't miss Windows.
Edit added:
Reasons why this is happening:
Bad connection somewhere.. The USB connection you are plugging in to on your PC could be messed up, the USB cord could be messed up, or where your type c plugs in to your device is messed up.... Oooorrrrr it's driver issue. And knowing Windows I betcha it's a driver issue. When you plug your tablet in are you enabling USB debugging and developer options and changing the "default USB configuration" from "Charging" to "File tansfer ?" And when you do those things are you watching the table REALLY CLOSELY for the little box that pops up for 5 seconds that you MUST put a checkmark in otherwise adb and fastboot will not work? Reboot a few times on your PC and update the drivers in Windows Device manager.. I remember once I had to reboot 3-4 times to finally get mine working. When you type adb --version then push enter in terminal and fastboot --version push enter what does it say?
