Hi, My android device is Android: 4.4.2, Kernel version: iBall3.4.67and MT6592.
Whenever I am trying to unlock its boot-loader, it’s failed. After ‘adb devices’ I see the ‘List of devices attached’. And after ‘fastboot oem unlock’, android device asks for permission. I confirmed on android device by pressing Volume Up but no changes on device screen and computer screen. Even after 45 min, there are no changes both screens. I changed USB cable and USB port. However, no changes. Even no images of TWRP is compatible for this device. Please guide me to fix it.
