Architecture

Some variants are released with Kitkat 4.4, which doesn't boot arm64 kernel, so upgrade to Lollipop 5.0 or later first.

Installation

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. Download lk2nd-msm8916.img from Releases page on Github.
  2. Boot your phone to bootloader (Odin/Download) mode by holding Volume Down and Home while powering up.
  3. Follow lk2nd instructions to install lk2nd. Basically flash it to the boot partition (heimdall flash --BOOT lk2nd-msm8916.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.
