Known limitations

Audio calls

While they work (headphones, speaker, loudspeaker), volume can not be changed.

oFono

Current oFono needs to be patched to work with the herolte. A precompiled binary can be downloaded here.

Installation:

# Remount system with write permission
sudo mount -o remount,rw /
# Extract archive and install new oFono version
tar xvf herolte_ofono.tar
sudo dpkg -i ofono_1.18*.deb
# Reboot

Wi-Fi

While Wi-Fi is working there is no reconnection after reboot. This is due to several things:

Issue with MAC address loader. Partially fixed and not published, need to be reworked as it prevents loading the right calibration file.
Unknown issue, probably a race condition between Wi-fi driver and Samsung's Macloader

MMS

MMS are working but a change needs to be applied until it gets merged to xenial

sudo ubports-qa install xenial_-_android9

Torch

Code is not yet merged in the xenial branch but it can be activated thanks to:

ubports-qa install indicator-power 48

Installation

The port is not ready to use the installer, yet :)

Fetch files and tools

Download and install the following tools:

Download the following files:

Unlock OEM installation

In Android activate developper mode thanks to this guide.
Then go to Android developer options and activate enable OEM unlock slider.

If this step is not done you will likely get the error Custom binary blocked by FRP lock when flashing halium-boot.img.

Install TWRP

Instal the TWRP recovery as instructed in its documentation.

Reboot to recovery and format data

From the computer enter adb reboot recovery.
Go to wipe->Format Data the enter yes as instructed.
Flash system.img thanks to ./halium-install -v -i -p ut ubports-touch.rootfs-xenial-armhf.tar.gz system.img.
Flash halium-boot thanks to ./Heimdall/build/bin/heimdall flash --BOOT halium-boot.img.
Wait, after the reboot, you should have UBports :-)
Some fix might be required, see Known limitations chapter.
