What works

  • Compiling the kernel and booting (!314)
  • Wifi with the proprietary firmware (!309)
  • Display
  • TouchScreen
  • Flashing via android recovery zip
  • Wayland/Weston/Xwayland

Notes

  • The device and kernel packages are basically just a copy of the Galaxy S7 Edge's packages. The only difference is that the two devices use different panels.
  • using command: apk upgrade can cause loading forever...

Mainline notes

For uniLoader:

  • To enable the framebuffer we need to write 0x1290 to address 0x13960070. To get this value search for the decon_f base address and add 0x70 (HW_SW_TRIG_CONTROL) to it, then use devmem2 together with the value you calculated on a downstream kernel with CONFIG_DEVMEM enabled.
  • The MUIC UART is located under address 0x14c50000. To get minimal output follow this guide (add 0x20 to the UART address for the TX offset).

Installation

  • Install TWRP recovery as described here.
  • Wipe the device while in TWRP.
  • Put device in download mode by holding the home, volume down and power buttons when powered off.
  • Execute $ pmbootstrap flasher flash_kernel to flash the kernel. (Note: You do not need to reflash the kernel if you want to reinstall PMOS with a different image)
  • Reboot Device into TWRP Recovery and execute pmbootstrap install --android-recovery-zip
  • While in TWRP, enable sideloading by going to Advanced -> ADB Sideload and then execute $ pmbootstrap flasher --method=adb sideload
