When I use the fastboot to unlock the bootloader it shows an error: "Press any key to shutdown". USB Debug and OEM Unlocker are enabled.

I Was trying to unlock bootloader on my Rogers(CAN) HTC One M9 (himault-att) but now my phone is unresponsive at the confirm unlock bootloader screen.
The commands I ran to get to the screen were:
Code:
fastboot oem rebootRUU
fastboot oem get_identifier_key
fastboot flash unlocktoken Unlock_Code.bin
After the last command my phone went to the Unlock bootloader? screen asking me to confirm or deny unlocking my bootloader and is no longer responding to fastboot or hardware keys.
All fastboot commands timeout after 5 seconds and return
Code:
FAILED (command write failed (Unknown Error))
however fastboot reboot times out at 5 seconds and returns finished. fastboot devices obviously shows my device as attached. My current plan is to wait for the battery to drain (it sucks not being able to pull the battery) and then attempt a normal boot. Any advice?

Hold power and volume up till the phone reboots and try again
If anyone can give me the following information it would be useful in adding the Pixel C to the Unified Android Toolkit.
1. Is the "Allow OEM unlock" option present in the developer options (needs checking before bootloader can be unlocked)?
2. What is the key combo to boot the device to fastboot mode manually?
3. Is it a standard bootloader screen (i.e. down volume and power to boot to recovery)?
4. What instructions do you get on the device after running fastboot flashing unlock to unlock the bootloader?
If anyone can fill in any of the information or add anything that would be useful then please do..
Mark.
1. Is the "Allow OEM unlock" option present in the developer options (needs checking before bootloader can be unlocked)?
A: Yes
2. What is the key combo to boot the device to fastboot mode manually?
A: Power + Volume down (when in landscape). The bootloader has an option to "Switch to fastboot mode" which you select with volume down and then the power button. It will switch to a screen that says "Waiting for fastboot command..." with no option to go back.
3. Is it a standard bootloader screen (i.e. down volume and power to boot to recovery)?
A: Yes. Here is a picture of it: https://goo.gl/photos/YQ5FVKf6HAWQWwd5A
4. What instructions do you get on the device after running fastboot flashing unlock to unlock the bootloader?
A: You are given the option to press power to unlock the bootloader or volume down to cancel. The device then says the bootloader is unlocked and it will reboot in 30 seconds. After that, you get the recovery robot with an "Erasing" dialog.

Thanks for the quick response. Just need a bit more info about the actual bootloader.
Do you know if fastboot commands can be sent after booting to the bootloader mode? Or do you have to boot to bootloader and then select "switch to fastboot" to accept an input? If you have used adb with the device could you run adb reboot bootloader and tell me if the device goes to the bootloader or the fastboot screen.
I also need error messages when unlocking. If you (or someone else) could run the following that would be great.
1. With "Allow OEM unlock" NOT ticked, boot to fastboot and run fastboot flashing unlock >> what is the exact error message.
2. With the device already bootloader unlocked, boot to fastboot and run fastboot flashing unlock >> what is the exact error message.
I think thats all thats needed for now to make a basic toolkit for the Pixel C to unlock, backup data, flash stock image, etc. If a custom recovery becomes available then it will then be very simple to add a root process.

I am heading to bed but if nobody has replied before I get to work this afternoon, I will be happy to get answers to the rest of your questions.

If I boot into the bootloader, I am unable to issue fastboot commands until I select "Switch to fastboot mode."
Using ADB, when I issue the "adb reboot bootloader" command when the device is on normally, it goes directly to the fastboot screen and says "Waiting for fastboot command..."
When "Allow OEM unlock" is not ticked and I boot to fastboot and issue "fastboot flashing unlock," I get no error message on the device, but I do see the following in the command prompt:
Code:
C:\>fastboot flashing unlock
...
FAILED (remote: Device already unlocked)
finished. total time: 0.005s
When "Allow OEM unlock" is not ticked, the bootloader is unlocked, I boot to fastboot, and issue "fastboot flashing lock," I get no error message on the device, but I do see the following in the command prompt:
Code:
C:\>fastboot flashing lock
...
FAILED (remote: Enable OEM unlock is not set)
finished. total time: 0.020s
When the bootloader is unlocked and in the fastboot screen, if I issue "fastboot flashing unlock," I get no error message on the device, but I do see the following in the command prompt:
Code:
C:\>fastboot flashing unlock
...
FAILED (remote: Device already unlocked)
finished. total time: 0.003s
Let me know if there is anything else you need.
Hello all,
A blessed day to all and many thanks to those who will answer.
The phone is on a bootloop and I can enter bootloader mode via Volume Down+Power. Tapping recovery doesnt work.
fastboot devices is OK. It shows the device.
EDL method doesnt work. The COM PORT wont show up.
fastboot bbk unlock_vivo doesnt work FAILED: (remote: unclock fail.)
fastboot vivo_bsp unlock_vivo. Nothing happens except shows the help text.
fastboot oem unlock doesnt work FAILED: (remote: unknown command or device is locked)
Is there anyway to flash a binary file just like in ASUS phones?
How can I unlock my bootloader?
Thanks in advance.
I've tried to unlock my device with enable OEM unlock in the developer options, because it is needed for enable VoLTE in my regions(with QPST). But it seems that device doesn't recognize it's allowed to unlock. Every advanced fastboot command in fastboot mode returns "FAILED (remote: 'Command not supported in default implementation')".
Is this possible to you who using the device to unlock the bootloader with fastboot? Or, OTA updates I've received blocked that?
How unlock the bootloader?My HTC U20 5G no download mode in bootloader !!!!!
Try
fastboot oem get_identifier_token --- error
fastboot flashing unlock --- error
fastboot oem unlock --- error
Yes I have the same problem. I thought it was Win 10, so I tried Win 7 as well, but got the same error there too.
Check if "USB debugging" and "OEM unlocking" are activated in Developer options

Yes, both options are activated (at least in my case).
Both commands "fastboot flashing unlock" and "fastboot oem unlock" result in "FAILED (remote: 'unknown command'), fastboot: error: Command failed".
I have no problem with Desire 20 pro and have no guess why it doesn't work with U20
C:\adb>adb reboot bootloader
C:\adb>fastboot devices
CN06D1V02*** fastboot
C:\adb>fastboot flashing unlock
...
OKAY [ 0.040s]
finished. total time: 0.042s

It also works with the U19e, very annoying that they changed it.

for anyone that might come across this problem. I had the same issue trying to use fastboot to relock my bootloader. Found the answer on another forum. I was using adb to reboot to fastboot mode to run the command. This was the problem. I needed to reboot to the bootloader to run the command

Try rebooting to the bootloader screen instead of directly rebooting. This solved my problem.
Hi there,
Just wanted to check in and see if anyone has managed to get bootloader unlocked?
Or is the htc u20 out of luck....

Hi, Just manually enter the fast boot mode with power key+Volume Up or Down depending upon the model and make, You can search this online how to enter Bootloader mode for one particular device. Once you are in Bootloader, Try Fastboot mode and Enter your commands. Should work
Anyone figure this out on Nord n200 5g T-Mobile variant? Please help
i am trying to unlock my vivo y20s bootloader but it doesn't works.
I tried the commands:
- fastboot bbk unlock_vivo
- fastboot bbk vivo_bsp unlock_vivo
- fastboot oem unlock
- fastboot flashing unlock
but with each different command it returns another issue
- with the bbk commands it says: "fastboot: usage: unknown command bbk"
- with the flashing unlock it says: "FAILED (remote: unknown command)"
- and with the oem unlock it says: ""FAILED (remote: unknown command)"
I have the oem unlock and usb debugging activaded also the last versions of adb, fastboot and the drivers but it's still not working
Hi there, I'm having the same issue. Have you been able to find a way around the problem?
