2. Type 'adb reboot bootloader'
3. Type 'fastboot oem unlock'
4. Use volume keys to select 'yes, unlock bootloader'
5. Use power button to select option
6. Done!
Lock Bootloader:
1. Open command prompt
2. Type 'adb reboot bootloader'
3. Type 'fastboot oem lock'
4. Done!
Is there an icon, like there was with the padlock on the nexus one, after you unlock it?

On the Nexus S, you can do fastboot oem lock and it's like it never happened.
Where are you getting the Nexus drivers? When I select the USB driver folder in the SDK (fully updated) it just tells me that no drivers were found.
Ha, I just saw this. Great.
[REF] "fastboot oem lock" will lock the device back
at least the bootloader screen shows it can be locked back.
not tried really locked my customized kernel yet.
will update after trying
I can confirm this.
So you can lock the bootloader back after you unlock it? COOL

If I type fastboot devices I get the "unable to locate componant" error which says "this application has failed to start because AdbWinApi.dll was not found. Re-installing the application may fix the problem".

I do have the latest. I don't see any USB drivers in the package but it does show up as an android ADB device. Now I'm trying it on my laptop and it will not find any USB drivers so it's showing up as unknown device.

I found those but those do not seem to work. When the phone is powered on it does show an ADB device but when in fastboot mode the drivers I downloaded do not work. So I need some samsung drivers or something for this?

I have the same problem too. The drivers installed fine for the device in normal mode. But once I go into fastboot, it is displayed as an "Android 1.0", with the yellow icon in the device manager.
Attempting 'fastboot oem unlock' it just stays there waiting for a device...
you need to manually install driver using "have disk".

If you are having issues with the stock usb drivers, then try this:

The part about installing PDAnet does fix the Android 1.0 driver problem, for me anyways. Once you get fastboot working, it seems fine to uninstall the program since it is still working for me.
The latest driver is version 4. You can open up the SDK Manager and download it. Look under available packages (I think that's what its called).

Yes. I've never had the Nexus One before, but the padlock icon did appear once I did the fastboot oem unlock.
So once we have clockwork recovery installed and rooted can we lock the bootloader with no problems?
I've tried the latest revision Android USB drivers from the SDK platform updater. I've tried PDANet and the Universal Naked Drivers.
Basically, ADB works great, but as soon as I "adb reboot bootloader", my Win7x64 says "USB Device Not Recognised".
I've already gone into device manager and tried manually updating the driver to the various ones I've downloaded. I've also tried "uninstalling" the driver and reinstalling it, but it keeps coming up as unknown device.
When I type "fastboot devices", nothing shows up (obviously).
What am I doing wrong?

Same thing happening with me, i want to re-lock my bootloader but when i am in bootloader mode windows does not want to recognize the device, i have tried everything too.
Did you install the correct drivers?
When connected and in the bootloader open the device manager in windows. You should see "android 1.0" near the top.
Update that driver. It should work.

Hey, As i said earlier i was having the same problem...try switching your usb cable then try. That is what fixed my problems.
ive done all mentioned above, even tried 3 different cables, no luck, anyone have suggestions
I dont know about what you want to do, but if you want to root and unlock use the wugfresh took kit. Its the bomb and as soon as I figure out where I can thank him and give a big kudos I will give thanks.

I could be wrong, but I don't think adb works from bootloader, but the fastboot command should. I think you can also use Google's Composite ADB Interface driver too for it (I can't reboot my N7 atm or else I'd find out).
I don't have any other android-related drivers on my system either, only Google's USB driver from the SDK. I'm also on Windows 8, but I would assume Google's USB driver would work fine on Windows 7 too.
Also certain USB filter drivers may cause issues too, such as libusb, or even AMD's USB filter driver (however, I had no problems). Or if you want to wipe out any/specific USB drivers, I recommend getting: http://www.nirsoft.net/utils/usb_devices_view.html
I updated to 4.3, which nuked my TWRP recovery. I have been trying to get TWRP back on my Nexus 10 so I can reroot. The problem is, my computer refuses to see it in Fastboot mode no matter what I do. The drivers are the main issue. I can't get ADB to detect my device in Fastboot.
I have followed all of the instructions on the Wugfresh tool exactly and I still have the same issue. By default, my Nexus shows up as a "Samsung Mobile USB CDC Composite Device" in Fastboot mode. It shows up as an ADB device in normal boot. USB debugging is enabled.
I have tried all of the drivers: Raw, PDAnet, universal, and Samsung. All are giving me the same result. I even plugged my Nexus 10 into another computer and tried the process from scratch and that computer also sees it as a "Samsung Mobile USB Composite Device". Changing the device manually to something like an Android ADB device will still not allow Fastboot to see it.
I'm all out of ideas here. I have uninstalled everything, removed all USB devices, rebooted, tried different computers, etc. Nothing is working. What am I missing?
Update: After several hours, I managed to get my computer to recognize it in fastboot long enough to flash the new TWRP manually and then got rooted from there. What a nightmare!
I am still having this problem. I tried all your steps and I am still having the problem.

I have followed Heisenbergs instructions to the letter but when I issue the adb devices command it just returns the string "list of devices" and that's it. Fastboot devices doesn't work either.
So I'm stuck at the start. Can anyone help me? From what I can tell I may need drivers but I'm new to this so I don't know.
I can give anyone more info if they need it.
I believe part of the instructions are to install the Platform Tools, which should include drivers. Try running the SDK Manager and updating or installing the drivers again. Also ensure you have USB Debugging ON in your Developer settings and OEM Unlocking enabled. Lastly, tap the notification in your shade about the USB connection (I think it defaults to Charging Only) and change it to various modes. Mine seems to only work on PTP mode. When you run the adb devices command you will need to authorize the connection on the phone end the first time by clicking OK so make sure the screen is on and unlocked so you can see it.
Hope this helps.

You enable USB debugging?
Me personally do not get any strings of data returned when im on fastboot
i open CMD, run ADB DEVICES, get message saying the port is opening, and then listing devices... which is empty
but i am able to flash anything i want using fastboot....
try this command and see if it works after that... fastboot reboot-bootloader
it should reboot bootloader for u.. thats a easy way to know its responding to u

It shows up in windows explorer as "Nexus 6p" when I plug in the USB cable.
I have USB debugging and unlock bootloader checked in settings.
My fastboot devices command returns nothing.

Did you change the USB mode? Mine shows in Explorer as you described but won't work in ADB/Fastboot until I change it to PTP.

Yeah I tried every option. Nothing.
The instructions say the fastboot devices command should return my serial number and it does not.
When booted into the bootloader one it tells me on one line phone LOCKED and on another line says download mode DISABLED.
Don't know if this has anything to do with my problems but I still cannot get a return on the fastboot devices command in order to proceed with the unlock command of "fastboot flashing unlock"
remember that u need latest fastboot for this to work.
did u updated the SDK manager to the latest? i had to do that in order to work for 6P

I had the same issue ,it was down to when I plugged the phone into the PC for the first time,it installed the Google.USB driver ,but it didn't install the driver for the adb interface,I had to download it from Google and install it manually
I also had the same issue, I had an old Clockworkmod generic driver that I was using for my Samsung Galaxy S5 installed.
Go to Device manager (either type it in the start menu, or: right click This PC, click manage, and click device manager), plug in your unlocked Nexus 6P phone and watch for a new item to pop up. If it says android something, uninstall it. I had to uninstall 3 times, then reinstall the drivers from the SDK before it would work.
I used the skipsoft toolkit to install the fb drivers; worked for me. http://forum.xda-developers.com/nex...ol-skipsoft-android-toolkit-nexus-6p-t3234159
but like others said, you may have to manually remove any that are already installed in windows, although I think that is one of the options in the toolkit.

I have my phone on bootloader mode, and "Android Bootloader Interface" is listed there. Even if I install the Samsung driver of the same name, it still says "no drivers are installed for this device". Fastboot commands won't work even though adb works perfectly fine

Update: Replacing the Google drivers (ADB, bootloader, etc) with Samsung ones in device manager broke everything so I had to reinstall the Samsung USB drivers, and uninstall platform-tools and the Google drivers through Android Studio
Adb/fastboot drivers work with Samsung drivers, not against.
Install both, don't set a preferred driver.
After that connect your phone while it's active on the main OS, the Samsung drivers will then properly install for your device.
Once the set-up is finished, boot into fastboot and plug your phone in using USB.
You computer should install generic drivers or specified bootloader drivers.

The driver issue was fixed by turning USB debugging back on, as I forgot to after I tested the validity of that done to death method to enable the OEM unlocking option, of setting the clock a week back and all, which my prediction was right of it being complete garbage. ADB now detects my device again and I'm able to reboot into the bootloader, but fastboot still does absolutely nothing

Yeah, sadly the a205u will probably never get root or custom ROMs. We have an extremely small chance since Samsung promised two major updates for the A20.
Either way, https://forum.xda-developers.com/android/software/tool-universal-fastboot-adb-tool-t3475832/amp/
Has the fastboot drivers if you haven't tried that one yet.
