# Building a Mobian Image for the Pixel 3a
## Prerequisites
Cloning the repositories
Kernel: https://salsa.debian.org/erebion/sdm-670-linux
Mobian Recipes does not have the changes merged, as the kernel is not yet part of Mobian: https://salsa.debian.org/Mobian-team/mobian-recipes/-/merge_requests/113
Take my temporary fork of Mobian Recipes instead, for now: https://salsa.debian.org/erebion/mobian-recipes/-/tree/erebion/sargo-build?ref_type=heads
The fork will be maintained until there are official Mobian images for the Pixel 3a.
## Compiling the Kernel
First `cd` to the kernel repo.
Then:
```bash
gbp pq import # import the patches to a patch-queue branch with the patches applied
ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- make defconfig sdm845.config sdm670.config usb-gadget.config # make kernel config, usb-gadget ist required for SSH via USB Cable
ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- make -j$(nproc) bindeb-pkg # make Kernel deb (one directory level up)
```
## Building the Image
First `cd` to the Mobian repo.
Copy the kernel deb to `devices/qcom/packages`, so that it gets installed onta the image we are about to build.
Temporary workarounds:
- Comment `loupe` in `include/packages-phosh.yaml` as that is currently not available in the repo. The image viewer can be installed later.
- Comment `mobian-phosh` because of a broken dependency and insert `phosh-core`, the metapackage just installs things like an XMPP client and nothing important we couldn't install later.
- Add your SSH authorized keys file to `overlays/ssh/authorized_keys`, important so you can log in later
```bash
./build.sh -t qcom -s -u mobian | tee mobian-build.log # -s for SSH, which we need later
```
(If you replace `mobian` with your own username, you will have to use that one for SSH later, of course)
Wait. It takes a while. Make sure the internet connection is stable, as the build fails if it cannot download all packages successfully.
Note: Your SSH Host Keys currently get generated while building the image, please don't give your image to anyone else.
## Flash to device:
```
fastboot --set-active --slot a
fastboot flash boot_a mobian-qcom-phosh-20240614.boot-bonito-sdc.img
fastboot flash userdata mobian-qcom-phosh-20240614.rootfs.img
fastboot erase dtbo
```
Boot up the device. Connect it via USB.
## Temporary manual changes
Documented in README.md in this repo.

# sargo-temp # sargo-temp
Temporary fixes that make Mobian work on sargo Temporary fixes that make Mobian work on sargo.
Please note that the MIT license does not apply to `qcom-firmware`.
## 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
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 dont have reason to believe sending wouldnt 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, udev rule in this repo does not look right yet)
- eSIM (supported, but needs a bit more testing)
- 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, 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
### 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 dont know how Kernel development works, so I would have never started porting without this project.
