This device is based on the Helio P23. 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: fastboot boot ing 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 MT6763 chipset; see the MediaTek Helio P23 SoC page and Volla Phone (volla-yggdrasil)/Hacking for more details.
Please note that as eMMC internal storage access isn't yet working you'll have to Netboot a postmarketOS rootfs over USB RNDIS!
As pmbootstrap flasher flash_dtbo
is a pre-requisite to booting mainline please backup your existing dtbo
partition contents to be able to boot downstream kernels/recovery images again with e.g. mtk r dtbo dtbo-backup.img
using mtkclient!
NOTE: Currently mainline ONLY boots with the (Android 9) firmware & bootloader that Ubuntu Touch also uses, so flash that beforehand through the UBports installer! Needs investigation what changes are required to boot with Android 10 bootloader... |
Patches of interest
