Good day!
Im trying to unlock bootloader to root the tab. Generally, i have followed a guide in a thread posted in this site (rooting zenpad c7 z170c) which was claimed to work with z370 by some. There were no problems encountered when using the method except when im already in fastboot, commands i enter like "fastboot oem unlock" return a "failure unknown command " from the prompt. I tried another command "fastboot flashing unlock" but the prompt returned "failure remote failure".
After that, i tried using "fastboot getvar all" and showed that bootloader is secured and still locked. I even tried "fastboot boot [root image name].img" but would cause an error since device is still locked.
I used win7 while doing this and got the adb installer 1.4.3 from a thread here.
All help is greatly appreciated.thanks

I have a Micromax A290 [Canvas Knight Cameo] which is rooted. I have installed adb and fastboot drivers in my PC running Windows 8.1. I am trying to unlock the bootloader of my device.
So I connect the device, type "adb reboot bootloader" and the phone boots into fastboot mode.
Next, I type "fastboot oem unlock" to unlock my bootloader.
The phone asks me for confirmation and I go for Yes.
Here is the problem.
After I choose yes, a message comes up in my device saying this:
"BOOTLOADER UNLOCK FAILED. RETURNING TO FASTBOOT IS 3s..."
I have tried everything I know. Used a different cable, used another port, but to no avail.
Please help me.
Thanks in advance.

Device: Yu Yunique
I flashed stock fastboot rom (YU OS) and it booted. After that, I did "fastboot oem lock" and phone not booting. fastboot not allowing me to flash another rom too.
I googled about this and it says I need to enabled USB debugging from dev tools. But since phone not booting, I am not able to do this.
Can anyone help please?

i tried to unlock my vivo y21l using adb command "fastboot oem unlock" but i get an error saying "device lock" message but my phone get identified by adb command so it's not a driver problem.is there any other way to unlock the bootolader? i just want to root my phone but not any one click methods are working so i guess it's because of locked bootloader maybe.thanks for anyone who can help.
