Fastboot mode

Hold the Volume down (Vol-) button and the Power button at the same time until the fastboot screen shows.

Installation

Use pmbootstrap to build your own installation image.

$ pmbootstrap init
$ pmbootstrap install
$ pmbootstrap flasher flash_rootfs
$ pmbootstrap flasher flash_dtbo # If your using the branch below with dtbo img (Note: try using if you get ssh issues)
$ pmbootstrap flasher flash_kernel

Downstream

There is a branch in my fork of pmaports which contains some dtc hacks to enable simplefb (note: it only shows for a few seconds, with no text - but there are some colourful penguins). It also contains modified firmware and device APKBUIlDs which use F07 firmware and builds a dtbo image.

Mainlining

Currently the phone boots a mainline kernel, but mainline tree is not merged in pmaports yet.

Component Model Status Notes
SoC Qualcomm Snapdragon 710 Y SDM710, is the successor to SDM670
EMMC Hynix-hC8aP Y
SD reader SoC interface (sdhci_2) Y Works
Display Custom Himax HX83112A Y
Touchscreen Custom Himax HX83112A Y Driver imported from downstream as the touchscreen is modified by vendor
Wi-Fi/BT Qualcomm WCN3990 P Only Bluetooth works for now
Back camera Sony IMX519 N
Front camera Smasnug S5K2x5 N
GPU Adreno 616 P Phosh loads fine but loading the GPU as in run firefox for example, causes the device to completely lock up

Notes

In order to connect to the device via usb (and ssh) use:

$ ip link set dev interface address 12:12:12:12:12:12 # You might need to set a mac address if not already set
$ dhcpcd interface --nohook ipv6


Make sure your coming from a C18 based ROM, as all testing has been done on that version of the firmware.

RUI1 seems to modify the bootloader, causing booting to fail.
