How to enter flash mode

Flash mode is entered by holding the power and the volume down key together when the device is off.

Installation

Note Note: Even though MSM8916 is capable of aarch64, the firmware of this device was never updated with aarch64 support. Therefore, this device can only boot mainline on armv7 at the moment.


lk2nd is a secondary bootloader that provides a standard fastboot interface, which can be used to boot postmarketOS without Android boot flashed or pmbootstrap flasher flash_kernel.

  1. The prebuilt image doesn't have the device included at the moment. Build lk2nd first.
  2. Boot your phone to bootloader (Odin/Download) mode by holding Volume Down and Home while powering up.
  3. Follow lk2nd instructions from step 2 to install lk2nd. Basically flash it to the boot partition (heimdall flash --BOOT build-lk2nd-msm8916/lk2nd.img)
  4. Follow Qualcomm_Snapdragon_410/412_(MSM8916)#Installation to install postmarketOS.
Note Note: Enter lk2nd fastboot mode by pressing only Volume Down + Power (without Home). Pressing Home additionally will bring you to the Samsung Download mode.

Screen

Screen works partially. While displaying the UI works fine, adjusting the brightness doesn't work.

Flash LED

Currently WIP. It can be controlled with SG Micro SGM3140 charge pump LED driver[1].

Accelerometer

lis2hh12 accelerometer is not so stable for auto screen rotation, which suggests you to use fixed portrait or landscape mode.
