So... I have been stuck with a HTC One E9+ for many months with a lock screen that I literally can't unlock, and flashed TWRP but can't be used because of locked bootloader, I had finally discovered a way to get the unlock token. Here's a little bit of story. I tried to run 'fastboot oem get_identifier_token' in bootloader mode, but the phone returned unknown command. I had tried that when everything was normal. I had check the settings in developer options, and there is nothing related to unlocking bootloader inside there. Until recently, I had discovered 'fastboot oem rebootRUU' from other blog post.
All in all, if you couldn't get the bootloader unlock token in bootloader mode, try to get it in RUU mode.
Good luck!
Hi, i tried to run the command "fastboot oem rebootRUU" but no code appeared.

fastboot oem get_identifier_token Copied the identifier token, and pasted it on My Device Identifier Token on HTCDev.com I downloaded and save the Unlock_code.bin in the root folder in my PC that is sent to my mail from HTC.com and finally run this: "fastboot flash unlocktoken Unlock_code.bin"

I am trying to fix the same issues with Verizon Wireless as well as I have tried the methods that are on here and still having issues
Please tell us what OS are you using, fastboot version.
Have you tried "fastboot devices" prior to launch the final unlock command? Maybe your PC to Phone connection was not ready, or you were in the Bootloader (you have to choose FASTBOOT from the Phone bootloader).
Another good thing to do would be to make sure that, within your Phone's Android, you have disabled the Fast Boot option. Phone-> Settings -> Power -> Fast Boot -> Unchecked
Hey guys
I just got my HTC one m9 today and the first thing I wanted to do, is to unlock bootloader for further recovery/root/ROM action.
So I tried like with other devices done before 'fastboot oem get_identifier_token' to get the token, fill it in at htcdev.com and wait for the unlock token.
But this new devices gives me an "FAILED (remote: unknown command)" error.
Is there any new way to unlock?!?
You need do be booted into download mode webdepp, looks a little like a stock recovery screen
Unlock bootloader LG G4 H815 Marshmallow.
Hi I have tried a lot but in vain.
My phone stuck every time at bootloader.
After installing sdk, adb and fastboot driver I gave the command to boot into bootloader every time it boots into bootloader according to the command. But never accept any command when it is in bootloader mod like fastboot oem device-id or fastboot reboot or any other.
So is there any solution?
I wanna Unlock My bootloader.
You need to enable "OEM Unlock" in developer menu (about > software info > build number (tap 5 times))
Hi,
I am using my Nextbit Robin Oem Unlock from last 1 year but today i decided to go back to stock with locked Oem.
I flashed the stock rom and locked the Oem at the same time but when i restarted the phone it got stuck at the boot.
So I went ahead with the 'fastboot oem unlock' command, and here's the problem. All flashing command returns FAILED <remote: device is locked...>.
fastboot oem device-info reads: Device tampered: false, Device unlocked: false. So bootloader is locked. At this point I assume that the bootloader is unlocked, but revert back to locked after reboot (the phone automatically rebooted after executing oem unlock command, so can't get around that).
Tried numerous other methods, using different adb files, no dice. Can't even flash TWRP. Tried adb sideload, same. Tried executing fastboot oem unlock with various different parameter, still locked after reboot. I cannot flash anything into locked bootloader.
Google researched it for few hours, same problem happened to other phones from other manufacturers that came returned from warranty replacement with modified motherboard; OR tampered/broken eMMC/NAND flash. But no such case for Nextbit Robin (yet?).
Pretty hopeless right now since I just found out that Nextbit Robin support ended on Aug 1st.
Guess I'm stuck with locked bootloader and no cell signal phone. Unless someone can help. One can always hope.
Anyway, thanks for reading.

If you bootloader is unlocked I think you can give a try to the Nextbit's Unbrick Tool
As you want to go back to stock , I think this is a good idea.
Now if your bootloader isn't unlocked there is unfortunately nothing I can do for you , unless you unlock it .
Edit #1: If your bootloader is locked , go to bootloader mode by pressing volume down + power button for about 20 seconds and try to see the bootloader state with fastboot commands. If it is unlocked , follow the process in the @nextbitKhang's thread .
Yes that's the main issue. Oem is Locked.
Is there any Oem unlock code i can use to unlock from ADB?
I don't think so ,I'm not sure, but I hope you'll find one.
On your Robin go to settings > system > about phone > tap build number until it shows developer options.
Go into developer options which is in settings > system > developer options.
Make sure OEM unlocking is enabled. (for good measure disable then re-enable)
Also make sure usb debugging is enabled. Have the Robin plugged into a computer so you can enable to pop-up on Robin asking for access for the computer.
Once they are both enabled shut down your phone. Turn it back on while pressing vol down+power and plugged into your computer.
In adb run command fastboot oem unlock
please i'm experiencing the same issue not on nextbit but on GIonee.
i have re-activate both OEM unlocking and USB debugging several times but it all void
same error: Remote: OEM unlock is not allowed
please kindly help
My razer phone, after the OEM unlock, unlocked it using two-party commands, wrote it into the lineage OS system, and then, cheap, used "fast boot flashing lock_critical" FastBoot flashing lock " After locking the mobile phone, it was found that the "Developer Options" had changed to not allow OEM to unlock. Now the mobile phone is restarted indefinitely, using the "fast boot flash unlock" FastBoot flashing unlock_critical " It can't be unlocked. Unable to write to the official firmware, nor can it start properly! Help, gods! Help me!:crying::crying::crying:
