Try these drivers: https://mtkusballdriver.com/download/mtk-usb-v1-0-8I am able to get FastBoot Mode on my screen (through step 6). I plug the phone back in per directions & I hear the Windows device connected chime.
I type: fastboot flashing unlock in the same cmd window
and I get "<waiting for any device>" in the cmd window and it hangs.
Every few seconds I hear the Windows device disconnected noise, but no device connect chime. This lasts indefinitely.
I repeated step 7 several times with variations with the Vol+ button: pressing first, holding down while pressing enter in cmd window, pushing afterward, holding down afterward, etc. Same results as described above.
Any help available? Should I not unplug my phone from the PC? The F2 directions did not require that.
(Uninstall old ones, if any, first, then reboot before installing)
