How to enter flash mode

Hold all the buttons at the same time until the 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.

The downstream kernel is pretty broken, so I am now focusing on mainlining this device.

NOTE: All the branches above where meant as throwaways, as such they are not maintained and commits are messy.

Mainlining

Currently the phone refuses to boot a mainline kernel.

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.
