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.
  1. Install lk2nd (alternative bootloader that provides a standard fastboot interface)
  2. Follow Qualcomm_Snapdragon_410/412_(MSM8916)#Installation.
Note 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.

Touch keys

For configuration of the touch keys, see Tm2-touchkey.

Display brightness

The brightness of the display can't be adjusted, this is not available yet.

Charging

There is no charger driver yet. The device charges – but slowly and there is no indication in the User Interface that it charges.

Suspend

Suspend is not yet fully implemented. It's recommended to disable suspend. See Qualcomm_Snapdragon_410/412_(MSM8916)#Suspend.

Modem

There is currently a regression in ModemManager 1.18.2. While ModemManager 1.16.6 first asks for SIM unlocking and thereafter queries the state of facility locks, ModemManager 1.18.2 does it the other way around. However, on samsung-serranove, querying the facility lock state before unlocking the SIM results in a QMI protocol error and a powered off SIM card.

There are temporary workarounds available:

A fix upstream is work in progress (ModemManager!710).

Plasma Mobile

On samsung-serranove the display natively shows everything in flipped/mirrored way. To compensate this, the cmdline in /etc/deviceinfo contains video=540x960,reflect_x. In Plasma Mobile of postmarketOS v21.12, the screen handling is done by KScreen. As KScreen doesn't support flipping/reflecting, everything is shown mirrored. There is currently no solution. See pmaports issue #1340.
