Firmware

Architecture

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

Boot modes

Fastboot (lk2nd menu) - hold Volume Down during boot, or (only for lk2nd Fastboot) - execute $ fastboot reboot bootloader on a connected USB host, or (also lk2nd) - select it on the bootloader menu by pressing Volume Down or Volume Up three times, then confirm using Power

Recovery (using lk2nd) - hold Volume Up during boot, or - enter Fastboot mode and select it on the bootloader menu by pressing Volume Down twice, confirm using Power

Recovery (using Samsung bootloader) - hold Home+Volume Up+Power, or (with USB debugging enabled) - execute $ adb reboot recovery on a connected USB host

DFU (Odin/Download) mode - hold Home+Volume Down+Power, or (with USB debugging enabled) - execute $ adb reboot download on a connected USB host

Hard reset - hold Volume Down+Power

Installation

Warning WARNING: Be careful when testing undocumented variants! Remember, we are dealing with Samsung here.


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

Only PulseAudio is working. Automatic device switching is unreliable when using it. See Systemd/audio for more details on PulseAudio.

Note Note: Playback issues may occur when playing FLAC files at high bitrates. Needs more testing/investigation.

Audio input devices

  • Primary microphone (Mic1) - Works.
  • Secondary microphoe (Mic2) - Works.
  • Headset input (3.5 mm) - Works. (?)

Audio output devices

  • Earpiece playback - Works.
  • Speaker playback - Works.
  • Headset output (3.5 mm) - Works. (?)

Note that the pop up volume bar is always empty in phosh. Could be a UI bug.

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!

Bluetooth Audio

Works. Has no known? issues.

DSP

See Qualcomm_Snapdragon_410/412 (MSM8916)#Audio.

Display

Screen works partially on this device. While displaying the UI works fine, adjusting the brightness doesn't work. Needs a driver.

Brightness

Currently unsupported.

Warning WARNING: Beware "burn in" when using an (AM)OLED display on high brightness! Permanent discoloration can occur after consistent long use. Especially on some low quality OLEDs.

Touch keys

See Tm2-touchkey for instructions.

Warning WARNING: Touch keys may not work on Duos variants. Confimed not to be working on SM-A5000. Needs testing.

Camera

Currently unsupported. You are welcome to try it!

Note The camera subsystem requires a lot of work. Needs more investigation.

Flash LED

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

Note Note: Driver seems to be abandoned as of 2025. Needs to be completed.

Image sensors

Needs more research.

ISP

See Qualcomm Snapdragon 410/412 (MSM8916)#Camera.

Storage

  • EMMC 4.5 - Works.
  • micoSDXC - Works.
  • USB 2.0 - Works. Requires OTG adapter.

Works. Supports microSD Cards and USB 2.0 storage devices.

Plasma Mobile

Plasma mobile currently works on A5 2015, but you should set custom scaling factor to 2.

kscreen-doctor output.1.scale.2 should work.

To run this command from ssh session add the following env variables to the above command:

XDG_RUNTIME_DIR=/run/user/10000 QT_QPA_PLATFORM=wayland kscreen-doctor output.1.scale.2

Plasma works smoothly, but there are some graphical glitches sometimes.

Ambient Light/Proximity Sensor

The driver for tmd3782 ambient light/proximity sensor is not available.

Mobile Data

  • 2G (EDGE) Data - Working.
  • 3G (HSPA) Data - Working.
  • 4G (LTE) Data - Broken.

Partial. You will need to got to Settings > Mobile Data, then select "Network Mode", then select 2G, 3G (Preferred) for Data.

Note Note: This could be caused by firmware/drivers/userspace not being configured for the 4G variant. The 4G connection does work on A500FU, but only if you have a SIM with no active data plan inserted. More research is needed, could be fixed if this really is the cause. Also see #Similar devices, serranove has a different 4G issue.
