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
