How to enter flash mode

Press Volume Down, Power, and Home all at the same time to boot to Odin mode. After lk2nd is installed, press Volume Down and Power at the same time.

Installation

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

lk2nd is a secondary bootloader that provides a standard fastboot interface.

  1. Download lk2nd-msm8916.img from Releases page on Github.
  2. Boot your phone to bootloader (download) mode by holding Volume Down and Home while powering up.
  3. Follow lk2nd instructions to install lk2nd. Basically flash it to 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.

Touchscreen

Sometimes the touchscreen stops working after idling for hours. To fix it, do:

# modprobe -r zinitix
# modprobe zinitix

Battery

rt5033 charger driver is not available, so the charging is not controlled and there is no charging status reporting.

USB OTG

Another rt5033 charger driver issue. Grand Prime is currently unable to power up a usb device in mainline. Try a hub with external power supply.

Accelerometer

gprime variants use bma, and fortuna variants use k2hh or k303c. k2hh accelerometer is not so stable for auto screen rotation, which suggests you to use fixed portrait or landscape mode.

Proximity Sensor

No interrupts received from gp2ap002s00f sensor.
