sargo-temp

Temporary fixes that make Mobian work on sargo.

What to do

Build Image

Instructions can be found in IMAGE.md in this repo.

Flash image

First flash the image. Boot the phone.

Connect via SSH: ssh mobian@10.66.0.1

Accept the host key.

Roll out workarounds using Ansible

You have to have ansible-playbook installed.

Go to the Ansible folder: cd ansible

Roll out workarounds: ./workarounds.sh

Reboot phone via SSH.

Connect to wifi.

Rolling out the workarounds for audio requires installing packages from the repo, so we need an internet connection.

Roll out audio workarounds: ./audio.sh

Project Status

This Works

• booting
• display
• touch
• modem
• plymouth
• battery/charging
• mobile data
• wifi
• torch
• suspend
• SMS (only receiving was tested, but I don’t have reason to believe sending wouldn’t work)
• vibration (udev rule needs to be added to the corresponding package)
• audio (ALSA config not packaged, but can be manually added using the playbook in this repo)
• Bluetooth™ (mac address currently has to be set manually after each boot, a udev rule for that can be manually added using the playbook in this repo)
• eSIM
• camera (front camera buggy, back camera works but patches not in git yet)
• GPS (needs some improvements to accuracy)

This Does Not Work (Soon)

• USB host mode
• call audio (requires packaging q6voiced to get audio from the modem, use the Ansible Playbook in this repo to build the package and install it... but of course VoIP would already work)
• full disk encryption (no installer images yet, once the other stuff is done this will magically be there)

This Has An Unknown Status

• Fingerprint Sensor
• NFC (no idea what software I could use for testing, but should work, does so on pmOS)

This Is Missing And Will Come Later

• accelerometer
• magnetometer
• ambient light sensor
• barometer

The Main Issues That Prevail

• A systemd unit with a hard-coded value, that has to be manually edited for now (droid-juicer.service)
• ALSA config not yet packaged, has to be manually copied for now
• few things to do for kernel packaging and then submitting that to Mobian
• no call audio yet, as the daemon (q6voiced) is not yet packaged, but can be manually added for now using the playbook in this repo
• simple script that brings up Bluetooth has to be added somewhere (for now this repo contains a udev rule... but something is wrong with it. For now just run "/opt/bluetooth-mac.bash" to get Bluetooth working, repeat after reboots.)

The Sources (Use The Source, Luke)

• My efforts of packaging a device-specific kernel: https://salsa.debian.org/erebion/sdm-670-linux (which will be used until all patches are part of upstream Linux and we can finally use a regular mainline kernel)
• mobian-recipes, which is used to build images: https://salsa.debian.org/Mobian-team/mobian-recipes
• droid-juicer, which retrieves some important files from some partitions: https://gitlab.com/mobian1/droid-juicer
• https://wiki.postmarketos.org (lovely folks, thanks for sharing everything you found out the hard way :D)

Thanks For All The Fish

Huge thanks to be sdm670-linux project and flamingradian who runs the project (just one person!) to make sure the Kernel works on those devices! :)

I don’t know how Kernel development works, so I would have never started porting without this project.
