Unable to unlock boot-loader

[Einfo Mail]

Hi,

My android tablet is iBall Brace-X1 which is….
· Android: 4.4.2
· Baseband version: iBallMOLY.WR8.W1315.MD.WG.MP.V34.P1,2014/09/28 15:07
· Kernel version: iBall3.4.67
· Build number: iBall Slide MJK Brace-X1_KK_V2.07,2016-01-12_19:19
· MT6592
And its RAM is 2GB and internal storage is 16GB.

To unlock boot-loader, I run in command prompt…
adb devices
List of devices attached
x.x.x.x device

fastbootoem unlock (after this command, I confirmed on tablet screen by pressing Volume Up but no changes on screen of computer and tablet. Even after 45 min, there are no changes on tablet screen and command prompt.)

I changed USB cable and plugged it in another USB port. However, no changes.

Please help me to fix it so that I can unlock its boot-loader.

Regards

Bootloader unlocking happens from when the device is in fastboot/bootloader mode, so you need to do something like this sequence:

c:\> adb devices

should display your device's serial #

c:\> adb reboot-bootloader

c:\> fastboot devices

should display your device's serial #

c:\> fastboot oem unlock​

Note/caution: unlocking a bootloader on an Android device typically wipes the device, so caveat emptor.

Cheers and best of luck!

Hi,

Thank you for replying.

Brother...I am aware of the above steps. And I did same that you explained.
After .. c:\> fastboot oem unlock

I confirmed on tablet screen by pressing Volume Up but no changes on screen of computer and tablet. Even after 45 min, there are no changes on tablet screen and command prompt. I changed USB cable and plugged it in another USB port. However, no changes.

Ah, good to know, for verification's sake.

I'm not at all familiar with your device, so there might be some other variable going on here...

Not sure what else to suggest .
