This device is based on the Helio G85.
See the SoC page for common tips, guides and troubleshooting steps

How to enter flash mode

  • Fastboot: Power on the device with both Power and Volume Up buttons held down. Then select Fastboot by pressing Volume Up and confirm with Volume Down.
  • Recovery: Do the same as for Fastboot, but select the Recovery option in the menu instead.
  • MediaTek Preloader: The preloader triggers automatically everytime the phone turns on or reboots.

Installation

Follow the usual flashing guide via pmbootstrap.

Note NOTE: fastboot booting is broken on this device, so e.g. pmbootstrap flasher boot won't work and as such kernels will always have to be flashed to the boot partition of the device.

Mainline kernel

There is some early mainline support being worked on for the MT6768/MT6769Z chipset; see the MediaTek Helio G85 SoC page and Hacking for more details.

Note NOTE: Currently earlyfb only works on the original non-multiboot-capable lk bootloader.
