Architecture

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

Variants

Model Codename Architecture Supported lk2nd
SM-G7200 grandmaxltezc armv7 ? ?
SM-G7202 grandmax3gdd aarch64 ? ?
SM-G720AX grandmaxlteub armv7 Y Y
SM-G720N0 grandmaxltekx armv7 ? ?

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.

Audio

Warning WARNING: The speakers are rather loud on 100% volume and may produce distorted sound that may damage your speakers after long use. Please make sure to use reasonable volumes - your ears and your speaker will thank you!

LEDs

The LEDs on the touchkey are gpio-leds, which can be controlled by subsystem leds and udev rules.

More information on LEDs handling can be found at: LEDs.

Battery

Actually a sec-fuelgauge with rt5033-battery driver.

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.

Ambient Light/Proximity Sensor

The driver for cm36686 ambient light/proximity sensor is not available.
