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 a6lte 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-a6lte.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 pmbootstrap flasher flash_kernel and pmbootstrap flasher flash_rootfs will probably work, but this is untested.

Alternative Installation

If installation with heimdall/pmbootstrap flasher fails you could use the recovery-zip method, see Installation_from_recovery_mode.

Note: if you desire to use the bigger partition, use pmbootstrap install --android-recovery-zip --recovery-install-partition=USERDATA

Mainline status

  • Pinctrl works, clock controller missing drivers
  • Display, touchscreen, eMMC and external sdcard full work
  • Wi-Fi sometimes works, but it seems that brcmfmac is not fully compatible with it
  • Fuelgauge works (thanks @Tooniis), but is not enabled in the current .config

Notes

  • Putting calls on hold and having several calls active simultaneously is not supported
  • Mobile data currently connects on IPv4 only
  • Wi-Fi does not connect out of the box. To connect to a network, after adding the network normally, open nm-connection-editor, edit the connection you're trying to activate, and set the "Cloned MAC address" setting to "Do not change".
