Probably, there is some errors in boot loader and your device doesn't go into Download Mode (DM). To unlock this device it is necessary to put the device into DM. You can try to repair (write working) boot loader via eMMC or USB and then try to perform the "Unlock" operation, if the device will go into DM. But there is a risk do damage device via repair procedure.
