Installation

  1. Install lk2nd (alternative bootloader that provides a standard fastboot interface)
  2. Follow the Installation guide
  3. If you don't install wifi firmware, display won't work
Note: Enter lk2nd fastboot mode by pressing only Volume Down + Power (not the Home button). Pressing the Home button additionally will bring you to the Samsung Download mode.

Audio

Everything is muted by default and must be enabled through alsaucm. Unfortunately, the tool is not very user-friendly.

$ alsaucm -i -c msm8916-samsung-a2015
set _verb HiFi
set _enadev <device>

where <device> is one of Earpiece, Headphones, PrimaryMic, HeadsetMic or SecondaryMic. (Speaker not supported yet...) alsaucm does not track which devices are already enabled, therefore it is possible to produce combinations that won't work properly (e.g. Headphones+Earpiece). To switch between devices, the old device first needs to be re-enabled and then disabled:

$ alsaucm -i -c msm8916-samsung-a2015
set _verb HiFi
set _enadev OLD
set _disdev OLD
set _enadev NEW
Warning: alsaucm sets the volume to maximum by default. It is possible to increase the volume even further, however, this may lead to permanent damage to your speaker!

Plasma Mobile

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

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

Plasma works smoothly, but there are some graphical glitches like choppy text
