Current oFono needs to be patched to work with the herolte. A precompiled binary can be downloaded here.
# 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
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 are working but a change needs to be applied until it gets merged to
sudo ubports-qa install xenial_-_android9
Code is not yet merged in the
xenial branch but it can be activated thanks to:
ubports-qa install indicator-power 48
The port is not ready to use the installer, yet :)
