This device has been archived. This means that it no longer appears in pmbootstrap and is likely broken.
It can still be selected in pmbootstrap init by typing in the vendor and codename, but you will have to build the kernel package manually.

This device is based on the Exynos 7870.
See the SoC page for common tips, guides and troubleshooting steps

Installation

The guide below was made for the downstream kernel package. For installing the mainline version, selecting Buffyboard or GNOME Mobile instead of XFCE might yield better results. If you encounter a problem during step 6, proceed with the alternative installation method.

Unlock the bootloader if not done.
Select a6lte and Xfce4 UI with pmbootstrap init
Generate the rootfs with pmbootstrap install to install Nura to the phone or pmbootstrap install --sdcard /dev/sdX to install it on an SD card.
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
Reboot into download mode
Flash Nura 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.
The phone should reboot straight into Nura.

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

Display, touchscreen, eMMC and external sdcard full work
Wi-Fi and Bluetooth work
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~~ Fixed, IPv6 is now supported too.
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". This should be fixed now, but YMMV.
There is an OFRP recovery available for this device, for the purposes of proceeding with the alternative install method.
