How to enter flash mode
Flash mode is entered by holding the power and the volume down key together when the device is off.
Installation
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. |
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
.
- The prebuilt image doesn't have the device included at the moment. Build lk2nd first.
- Boot your phone to bootloader (Odin/Download) mode by holding and while powering up.
- Follow lk2nd instructions from step 2 to install lk2nd. Basically flash it to the boot partition (
heimdall flash --BOOT build-lk2nd-msm8916/lk2nd.img
) - Follow Qualcomm_Snapdragon_410/412_(MSM8916)#Installation to install postmarketOS.
Note: Enter lk2nd fastboot mode by pressing only | + (without ). Pressing additionally will bring you to the Samsung Download mode.
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: 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. |
Flash LED
Currently WIP. It can be controlled with SG Micro SGM3140 charge pump LED driver[1].
Note: Driver seems to be abandoned as of 2025. Needs to be completed. |
Accelerometer
lis2hh12
accelerometer is not so stable for auto screen rotation, which suggests you to use fixed portrait or landscape mode.
