Hello,
I can not reach Fastboot mode in my new HTC Desire 626G. The only menu I reach is “Factory Mode” with "Vol-"+"Power". There are 4 submenu "Item Test", "Clear Test Report", "Version" and "Shutdown" which are not very useful. I found lot of people that have same problem but no Answers. Maybe you can help me.
HTC Desire 626g
OS: 4.4.2
Build: 1.06.401.1
Kernel: 3.4.67
I am one step closer but still far away from success. As you may think I am trying to unlock my bootloader and root my device.
I use adb to reboot the phone into fastboot moode (because I do not know adb so well I used “HTC Bootloader Unlock” tool which did it for me).
But now “fastboot oem get_identifier_token” or other oem commands doesn’t work -> “FAILED (remote: unknown command)”. I assume that I should enable "OEM Unlocking" (like in Settings->Developer Options) but there is no such option in Android 4.4
Does anyone have advice for me? Should I contact HTC support?

Hi,
I am unable to unlock the bootloader on my Nexus 6, which was purchased new from Amazon.com. Or more accurately, I can issue the fastboot flashing unlock command without error, but my phone still says LOCKED and screen is frozen for 60 seconds.
I have followed the various HOWTOs on this website to the best of my ability:
1. Installed latest Android SDK tools(25.1.4.rc1), Platform-tools (24rc2) & Java8. I originally installed with the 23.1 platform-tools but then moved to the preview channel release when I had no luck.
2. USB debugging and OEM unlocking are both ON
3. Both "adb device" and "fastboot device" show my phone's serial number when in their respective modes, so I know communication is good between my laptop and phone.
How to replicate problem:
a. With my phone connected, I first issued "adb reboot bootloader". My phone then sucessfully changes to the AP Fastboot Flash Mode (Secure) screen. Beneath the green BATTERY OK (Charging) are the lines
Device is LOCKED. Status Code: 2
Transfer Mode: USB Connected
b. I then type "fastboot flashing unlock" and the output is
...
OKAY [ 0.016s]
finished. total time: 0.016s
However my phone does not ask me if I want to unlock. In fact, the screen then appears to be frozen -- pressing the volume up and down buttons does not change the power button selection menu. If I try to issue any other fastboot command, it says FAILED (command write failed (Unknown error)) finished. total time: 5.017s
The screen is frozen for 60 seconds. After that, the bootloader screen is once again functional (I can change menu options again) and I can issue new fastboot commands, such as 'fastboot reboot'
However, the device still says LOCKED and will refreeze for 60 seconds if I type 'fastboot flashing unlock'
Any suggestions would be appreciated!
Thank you.
type fastboot oem unlock to unlock your bootloader, then follow instruction. But beware, this will wipe your device

In newer versions of fastboot, the command is fastboot flashing unlock, not OEM unlock.
Code:
$ ./fastboot
usage: fastboot [ <option> ] <command>
commands:
update <filename> Reflash device from update.zip.
flashall Flash boot, system, vendor, and --
if found -- recovery.
flash <partition> [ <filename> ] Write a file to a flash partition.
flashing lock Locks the device. Prevents flashing.
flashing unlock Unlocks the device. Allows flashing
any partition except
bootloader-related partitions.

No, I had not. I tried using fastboot oem unlock on an older version of the SDK toolkit and that had failed, but I had not tried using oem unlock again on the latest version, having noticed that "oem unlock" was no longer listed as an option.
I just tried it now on the latest SDK toolkit and it does indeed work for me. :good:
Thank you to the both of you for helping me out!

Welcome
i do believe the "fastboot flashing unlock" is for when a manufacture issues a binary token kinda of like how HTC does it. If the Nexus or any phone that is not carrier branded, "fastboot oem unlock" will be the command to pass.
I rooted my Nexus 6 in an attempt to install nethunter linux distro by Kali. I was using the Nexus Root Toolkit v2.1.9. The phone will connect to PC and I can get it to load into fastboot with the normal options available but the bootloader is locked. When attempting to use any recovery option the phone boots to the "Google" logo and then flashes the android icon laying down with the red triangle and the words "No command" then shuts off. I have searched numerous threads and articles on the internet I keep getting stuck at the bootloader locked.

Rebooting your device...
First thing to do is ditch the toolkit. Learn how to use ADB via the command line. Second thing to do is download an OTA image from Google and sideload it. That should restore your device to operating condition, despite the bootloader being locked. All data on the device will be wiped when doing this.
I have used the ADB / Fastboot cmd lines within powershell but each time I try to flash the bootloader I get the
(bootloader) Not allowed in LOCKED state!
FAILED (remote failure)
Are you in recovery mode when trying to sideload the OTA? If not, you need to be. The only command needed is "adb sideload [ota]".
As long as Allow OEM unlock is checked in developer options, you can unlock the bootloader via fastboot, with fastboot oem unlock.
@Char_G: I guess I read "OEM Unlocking Enabled" differently, i.e. wrong, when I attempted to help him.

I've always unlocked my bootloader as soon as I got the device so I've never seen that particular text before, I'm assuming it means that he's checked that box but I don't know for sure lol
when running the command in powershell i get
PS C:\Users\n0n3m\Desktop\android-sdk-windows\platform-tools> ./fastboot oem unlock
...
(bootloader) Check 'Allow OEM Unlock' in Developer Options.
FAILED (remote failure)
finished. total time: 0.003s
the phone will no longer stay on the android with the red triangle to allow me into the recovery mode option to select sideload with adb

Sounds like it flash stock recovery hold power button and press the volume up key that should allow you to select adb sideload in recovery

But you saying that it won't stay on screen long enough to get into recovery.. that's strange. I haven't experienced this before

To regain root, simply use
Code:
fastboot boot
and drag and drop the TWRP file and press enter, and install root of your choice.

This is 2 months late, but if you're still looking for a possible solution, this is what I did:
1.) Download the tools you need here: https://developer.android.com/studio/releases/platform-tools/ and extract
2.) Install LG United Mobile Drivers from here: https://lg-united-mobile-driver.en.lo4d.com/. I recommend uninstalling previously installed LG G4 drivers from Device Manager and then reinstall from that page. You may need to install additional drivers once you connect your G4 to your computer.
3.) In Developer Options, make sure you have "Enable OEM unlock" checked and "USB Debugging"
4.) Open a command prompt in the tools directory (hold shift, right-click inside the folder, and click "open command prompt here." If you've authorized your device to be recognized by your computer (two prompts should popup: one to allow USB connection and another to allow USB debugging), your device should be listed if you enter the command "adb devices"
5. Enter "adb reboot bootloader"
6. Once the phone has rebooted into the bootloader, you should be at the stage where you get the text on your phone, as you described. Enter "fastboot oem unlock"
7. Check if you've unlocked the bootloader: "fastboot getvar unlocked"
8. If successful, you can then go on to flash TWRP onto the recovery partition and root your phone by flashing Magisk from there.
Hello .. I have a LG G4 811 t mobile32GB phone, what is the appropriate flash?
Hi, I have problem with unlock bootloader in my moto G7 power because my firmware is broke I have Unlock Code from Motorola site when use command fastboot OEM unlock #code receives a message (bootloader) Check 'Allow OEM Unlock' in Android Settings > Developer but I can't enable developer options because my firmware not work, I can only enter fastboot mode. I tried to run developer option from ADB but I have empty list devices even though I have installed drivers Android ADB Interface. I tried to install stock firmware but I need to unlock bootloader first. Does someone have an idea for this problem??
Hello,
I have a brand new Xperia XZ1 Compact (G8441) and I'm setting out to install LineageOS on it.
I understand the first step is to unlock the bootloader. I have followed Sony's instructions here but I get this error when I run the fastboot unlock command:
./fastboot oem unlock 0xE8475F4F6417A194B (I also tried without the 0x)
FAILED (remote: 'Incorrect format for unlock data')
I then tried following a different article at getdroidtips but I get this error:
./fastboot -i 0x0fce oem unlock 0xE8475F4F6417A194B
fastboot: invalid option -- i
I'm also confused if I even have to run the above commands because I managed to enable "OEM Unlock" from the Developer options menu. This OEM Unlock option wasn't initially visible when I first enabled Developer Options so I'm curious why it suddenly appeared.
Any help would be greatly appreciated, thank you!
