How to enter flash mode

  • Recovery: Power on the device by holding Volume Up and Power.
  • Download: Hold Volume Up and Volume Down while plugging the device to a computer with an USB cable.
  • Hard reboot: Press and hold Volume Down and Power for 7 seconds.

Unlocking the bootloader

  1. Enable developer mode by tapping on the build number seven times in Settings → About phone → Software information
  2. Return to the main settings page and go to the developer options
  3. In developer options, enable OEM unlocking. Make sure you have an internet connection if it doesn't show up.

Installation

  1. Unlock the bootloader if not done.
  2. Select j6y18lte and Xfce4 UI with pmbootstrap init
  3. Generate the rootfs with pmbootstrap install to install postmarketOS to the phone or pmbootstrap install --sdcard /dev/sdX to install it on an SD card.
  4. Generate the flashable images with pmbootstrap export. They will be stored in /tmp/postmarketOS-export, or you can specify another location like this: pmbootstrap export /home/user/Downloads/pmos
  5. Reboot into download mode
  6. Flash postmarketOS with heimdall flash --BOOT /tmp/postmarketOS-export/boot.img --SYSTEM /tmp/postmarketOS-export/samsung-j6y18lte.img (replace the paths if necessary). If you installed to an SD card, specify only the BOOT argument. Also you may choose the bigger USERDATA partition for the system image.
  7. The phone should reboot straight into postmarketOS.

Note: installation with heimdall flasher flash_kernel and heimdall flasher flash_rootfs will probably work, but this is untested.
