I am trying to root my phone using Ubuntu. When I try
adb reboot bootloader
My device boots into fastboot mode
When I try
It list my device. But when I try
fastboot oem unlock
It freezes with 3 dots. Any idea what is the issue?
Not every device is rooted the fastboot way like Nexus phones do, especially when the device in question is a MediaTek one.
I did a quick search and the result checks out: you'll need MediaTek's scatter flashing tool. Read this: LINK: XDA-Developers
I don't have the device so it's up to you to verify whether this works. Either way, do hang around XDA and other forums often for this sort of info.
