I have somehow installed the fastboot drivers for my Pixel C (although ADB still doesn't work), and have successfully (?) unlocked the bootloader.
If I try to flash either the newest bootloader in order to install the N Developer Preview or a TWRP image, I get the following message:
FAILED (command write failed (No such device or address))

I tried different USB ports but the result was the same. I found somewhere about fwtool, but in order to use that I have to be rooted (if I understood correctly).
Any other ideas?

I'm assuming that since you were able to "successfully" unlock the bootloader that you can do this to check and see if your PC still recognizes your device. So, while you have you're Pixel C in fastboot and have it connected to your PC, open a command prompt and type the words fastboot devices and see if it returns your device serial number. Normally the command prompt will show that message when your device is not properly connected with the correct drivers installed. Also, if you have the correct drivers installed your ADB should work if you have enabled USB Debugging in developer options.

Well, fastboot devices (and all fastboot commands) works. As for ADB it shows my device, but says unauthorized and never asks for my authorization.
But the thing is that I cannot flash anything.

Okay. If it will recognize fastboot commands let's start over from the beginning. Go to developer options and verify OEM Unlocking is checked and USB Debugging is checked. If you have the correct ADB drivers installed you will receive a pop-up message that says "This computers RSA key fingerprint is xxxxxxxxx. Check the box to always allow. Next, boot to the bootloader and type fastboot devices in a command prompt window. If it returns your device serial number then we are good to go.
Next, open a command prompt window and type fastboot flashing unlock. (may have to use fastboot OEM unlock) I've seen both work for some reason. If you are successful your Pixel will give you a message saying the bootloader is unlocked and OS verification is off. Once it's complete it will boot into the bootloader again. Once this happens, boot normally and hurry through the setup wizard so you can enable developer options and enable USB Debugging.
Now, once this is done boot to the bootloader and open another command prompt window and type fastboot devices to verify you are connected. If you are connected then you can fastboot flash the Android"N" bootloader and install the developer preview. Lemme know how you make out.

Thanks for the very descriptive post. The thing is that I have already done all that, with the exception of using ADB, the pop-up never appeared and my Pixel C appears as unauthorized in adb devices.
I know for a fact that the bootloader is unlocked, because everything got wiped afterwards, and I also get the message saying that the bootloader is unlocked in every boot.
The thing is I cannot flash neither the developer preview nor the TWRP image. I read somewhere about a similar thing some users had on Pixel C, but the solution was to either do something via TWRP or use fwtool that needs root. And I can do neither.
So that's why I started this topic to see if anyone can think of anything else.

On thing to try is to go into the settings Developer Options and "revoke USB debugging authorization". Connect to PC and you should then be asked to allow the "fingerprint". Hopefully that will fix it. I assume you've tried changing the connection type - charging, File transfer etc. If you are using W10 Pro then you may have driver issues. There are many posts on the net about that os and Google's driver but I've yet to find a definitive answer, I now use a USB C card see http://forum.xda-developers.com/pixel-c/help/windows-10-pixel-c-type-c-ports-t3414423

Hello friends,
How to get into fastboot to relock the bootloader, if my volume button is dead? By dead, I mean the ribbon has been ripped off of the mobo (it was soldered onto mobo).
Since I'm a brand-new noob, the only way I know of and have done is to get into fastboot mode and lock it back up like what I did when I unlocked it. Any other way to lock it, ideally within the Android OS? Since my volume buttons are completely dead, I doubt that I can get into any "mode" other than OS right now..
TIA!
adb reboot bootloader.
I've seen that command in a post from search earlier, but there was no response after that post.
Would you explain the procedure? I am afraid that I might do anything wrong on top of these disasters i've gone thru with this phone
I also saw another line during earlier search: "if they don't know how to setup an adb command, they probably shouldn't unlock their phones"... Looks like I've done what I shouldn't..?
I would say doing whatever ripped the volume button cable out was what you shouldn't have been doing If you unlocked the phone you have the software you used to unlock, right? What software/guide did you use/follow? Are you using Windows/Linux/Mac? The only way to get to the bootloader w/o the volume buttons (afaik) is to use adb via usb. If you provide more details I can try to help you.

Once you're in adb reboot bootloader, do fastboot oem lock. Opposite of how you unlocked it in the first place

navigate your cmd line to the folder with adb and fastboot in it. Hook the phone up to the computer and type:
Code:
adb reboot bootloader
which will make your phone reboot into the bootloader mode. You can then proceed with what you need to do.

I agree with whoever said that. This is another example of people messing with things before reading and learning how they work.
Thanks for your help guys!
btw, anyone found xdadevelopers to load extremely slower in Firefox when compared to Chrome? (just offtopic)
Anyway, I unlocked the bootloader when I was switching to yakju cmd and this folder called "fastboot-and-adb" in which there is both adb.exe and fastboot.exe. I used command "fastboot unlock bootloader" or something alike.
I'll do some more search and learn. Don't want you guys to think of me as a lazy bone who unlocked their bootloader using 1-click toolkit
p.s. edit: in my other thread, someone suggested using quickboot app.
Thanks for your replies guys!

Somehow it says device not found
I do have proper driver (Naked Driver Beta 0.5 by 1wayjonny) that my phone was able to be recognized under bootloader at the time when I could actually get into bootloader. My phone is also being recognized as media device now... I have also turning usb debug on...
Try adb remount
The ad devices
This should list the serial number
Then all commands should work

You need to turn USB debugging on, and then type "adb devices" and see if it shows up. It may not using the Naked Driver; I had to install the full Samsung USB driver package before ADB would see my Galaxy Nexus.
If it does show up, then you type "adb reboot-bootloader" and it should boot into fastboot. Then just type "fastboot oem lock" and it will wipe the storage partitions and restore the bootloader lock.
Thanks for the help at late night guys. I finally got into the bootloader, thru a mac tho Kinda ironic that I am a supporter of Windows, well, at least a firm user of Windows.
Tried adb remount, it still says device not found

I believe that you quoted my "I have turned USB debug on" ;p
Gave up on trying Windows drivers. When I was flashing the Yakju, I tried Samsung full driver, and it didn't work on my machine, i.e., the phone can't be detected in bootloader mode, while the beta 0.5 driver worked. So I decided not to mess with it anymore.
It looks like when the phone is not under bootloader, windows recognize it fine as MTP devices and install proper samsung driver from the internet directly. This allows me to open it up in explorer to browse files and such, but the phone won't show up under adb devices somehow.
Looks like MTP device (when the phone is in Android OS) and the fastboot mode use two kinds of drivers. This is just my assumption, though.
Anyway, finally got into bootloader now with Mac, and it's pretty funny I have to do everything thru command as the volume rockers are dead
And most importantly, thank you guys for your help!
Just another update
It's real funny now that the bootloader is locked, I can't unlock it again cuz I don't have the volume button working, so I couldn't choose YES on the phone.
I'm not trying to unlock it again, but just to confirm if there's really no work around, in case I encounter this situation again in the future
Lucky that locking the bootloader won't erase everything, or I won't be able to flash a ROM with it locked... :cold sweating:
Hey guys,
I followed this thread to unlock boot loader (http://forum.xda-developers.com/showthread.php?t=2694600), used the automated way to install adb drivers and did everything like the post says, but when I boot into bootloader and connect to my pc, when I type an adb command to get the code, it just stays at waiting for device for ages...
What I'm doing wrong? I even updated to the last api of adb, which are on the automated post (http://forum.xda-developers.com/showthread.php?t=2588979), posted by an user.
Can anyone help me please?
Thanks in advance!
You don't use ADB at the bootloader, you use fastboot. ADB is only when Android is running

This method does not require you to boot into bootloader. It does require S-off, however. Notice the instructions only tell you to boot into bootloader as the last step, simply to verify the unlock was successful.
Confused...
What? I don't know what to next then... I installed the automated way drivers, installed HTC connect program and allowed the connection via usb in developer options... What shall I do next to unlock boot loader?
For what I see on the VomerGuide it says after:
"Enter Fastboot (bootloader) Mode" ... now you are telling me that I do not need to...
When I enter in this Fastboot Mode, I connect the device to pc and then say the command to get the code, but it says waiting for device for ages and doesn't give me the code... Can you explain me what I'm doing wrong/what shall I do next?
Thanks in advance!

Make sure "usb debugging is enabled" on your phone, then cmd "adb devices" on PC and it should return your phonr serial number.
Will try that.
BTW, shall I enter in bootloader and then connect to PC, or do the other way around?
Thanks!

My apologies. I was looking under a different page from the link you provided. If you are following VomerGide, yes you do start in fastboot.
Try this first, though. Make sure USB debugging is enabled, leave phone on (not fastboot), plug it into your computer, and cmd "adb devices". If a message comes up on phone screen to allow computer connection, choose to always allow. Once you have gotten adb to recognize device, you can cmd "adb reboot bootloader" and phone should reboot into bootloader. In bootloader screen on phone, you might have to select fastboot mode. Then try to cmd "fastboot devices" and see if it brings up you device info. If so, you are good to go!
hey guys, I just got my OP3, I want to open the bootloader before I store some data that will be erased anyway when unlocking, I enabled USB Debugging & OEM unlocking & Advanced reboot and then I accepted the RSA Fingerprint popup. (Then, when running adb devices, I got the id of my device).
Now, I am in bootloader mode, and when running fastboot devices, I get nothing. I already installed Oneplus drivers when first connected the device.
In Device Manager under Other Devices I can see a device named "Android". When trying to install the drivers manually by browsing devices I have on my computer, I can only see "Samsung ADB Interface" and I am afraid installing this will not work when trying to unlock the bootloader. What can I do? I also have a Kali Linux Laptop if that's helping. Thanks.
Put in fastboot mode, connect to computer and manually select fastboot interface from the device manager "install device/update driver manually" box. That worked for me.

Its fine just search for fastboot devices and see if your device comes up. Mine was showing the same thing and i continued and it worked
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

I also have this problem drivers are installed and fine but when I go to fastboot within like 15 sec it automatically turns off.
I fixed it with this https://forum.xda-developers.com/attachments/howto_driver-zip.2480396/
I wanted to root my razer phone 2 because I rooted my old Samsung, but after unlocking my bootloader I decided against it and now ive spent about 2 days trying to lock my bootloader again with no luck.
ive tried many different usb drivers and non of them show my device under the "fastboot devices" command in adb or fastboot but I can show the device under adb devices which im aware is rather easy
ive seen many people have this issue but they don't really show/tell how its fixed! ive tried different usb sockets too!
the device name in my device manager is "SAMSUNG Android Phone" (while the phone is in fastboot mode) with the sub driver called "Android Bootloader Interface" if anyone has any kind of advice or tips to get my bootloader locked again please share!
okay, so after a lot of looking around.. I found this.
"1) - To unlock the razer phone bootloader do the following
2) - Install ADB + Fastboot and google usb drivers
3) - Enable developer mode by going to settings, about phone and hitting build number a bunch of times. then go back to settings > developer options and check USB Debugging and OEM Unlock.
4) - Open a command prompt on your PC and connect the phone's usb cable to your computer. Accept the prompt on the phone for trusting the computer when plugged in.
5) - type the following in command prompt without quotes "adb reboot bootloader"
6) - You'll be at the download mode screen with the razer logo.
7) - Make sure the driver for ADB Bootloader Interface was installed. If not you'll probably have a device called Android under "Other devices" in device manager. If this is the case, install the google usb driver.
8) - In command prompt type the following without the quotes "fastboot -i 0x1532 devices" and make sure your device comes up and not just a blank response.
9) - If it came up now just type without the quotes "fastboot -i 0x1532 flashing unlock"
10) - This will bring up a prompt on the phone itself to unlock the bootloader, use the volume button to navigate to yes and press the power button to confirm.
11) - The phone will reboot and will show a message stating "Your device is unlocked and cannot be trusted" on each boot to show that it is unlocked."
FIX - it was the "fastboot -i 0x1532 devices" I was doing wrong.. I was not putting the "-I 0x1532" i now feel stupid.. but idc i locked my phone and im back to stock finally! (ill probably end up trying to root it again some point in the future :| )
