Hey guys.
Is it possible to root without unlocking bootloader? I ask this, because every time I tried to unlock the bootloader I get the warning "Failed to get unlock data"
- I'm using Android 11
- "OEM Unlock" and "USB Debugging": checked
- Drivers and adb: installed
- Tested on all computer usb ports
Fastboot recognizes commands (example: fastboot reboot bootloader). However, it does not return the code to unlock the bootloader.
Thanks for help!

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.
Hi Guys
I am unable to unlock my bootloader. I have downloaded adb and fastboot drivers. I connect device. run adb devices, device details are displayed. i then run command to reboot into the bootloader. it reboots into the bootloader. when i run fastboot unlock oem nothing happens.
I have enabled the developer options, USB debug, OEM unlock, Advanced reboot
is there something I am not doing right?
adb is working in your system but fastboot is not working.
Check your drivers properly, they are not installed properly.
search for how to install adb and fastboot drivers on windows. There is no problem in windows xp but in windows 10 as in my case, you need to activate the developer option in setting and manually install the drivers. Go to device manager and check if your device is showing as android device when you go to fastboot mode.

Did you type fastboot devices?
It should show you that your phone is connected.
Then you can run the unlock command.

This setting is inactive (grayed out) after unlocking.
Finally problem solved.
There was somethig wrong with adb interface driver. After unlocking bootloader i have to reset developer settings to defaults to get usb debbuging work again. After this OEM unlock setting resets to, but because it stays inactive its imposible to turn it on. So i relocked bootloader and used Huawei Multitool drivers to unlock again and install TWRP.
Hi, so my Xiaomi MI A2 is kinda not working and I think that wiping cache partition might help but I can't access the recovery so I wanted to install TWRP. The thing is I have the boatloader locked, I have the USB depuration activated but not the OEM, so how can I unlock boatload or unlock OEM via fastboot?
Thanks

It won't let me. It says:
my command: fastboot oem unlock System: FAILED (remote "flashing unlock is not allowed")
Fastboot: error: command failed.
Same with the critical. I also had an error trying another command, it said, not allowed in lock mode.
Actually, I'm trying other commands and it's the same error with all comands.

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!
I was able to get it to work on a windows machine, after installing this:
