imsd turns out to be fully public already (0.2.7 snapshot + emergency stage 1 + the make build path) - no tag needed, same git-archive dance as the kernel. callaudioshim was a load-bearing unpackaged home-dir script on the phone (callaudiod replacement, working in-call mic mute); now an aport autostarted at phase 1. kde-telephony's modem daemon autostart is hidden via /etc/skel from the imsd package, mirroring the phone's user override.

fp6-img
Flashable postmarketOS images for the
Fairphone 6, built nightly from the
Catcrafts milos-linux
combined-stable kernel branch, with
imsd (userspace VoLTE)
preinstalled.
Maintained by Jorijn van der Graaf (TheMightyCat) at Catcrafts.
Caution
Emergency calling is unverified. Calls (including 112/911) go through imsd, whose emergency path is spec-shaped but has never been verified against a live network. There is also a known kernel bug that can wedge the modem data path until reboot. Do not rely on a phone running this image to make emergency calls.
What works
Everything on the combined-stable branch: display, touch, wifi, cellular
data, NFC (reader), speaker audio, microphone, IMU, magnetometer, barometer,
ambient light/proximity — plus VoLTE calls (both directions) through imsd.
Verified on exactly one device / one carrier (KPN NL). Reports from other carriers are very welcome.
Flashing
Download boot.img and fairphone-fp6.img from the latest release, unlock
the bootloader (Fairphone's official process),
then:
fastboot flash userdata fairphone-fp6.img
fastboot flash boot boot.img
fastboot reboot
Default login: user / 147147 (same as official postmarketOS images —
change it). Never re-lock the bootloader with a custom image installed.
VoLTE configuration
imsd is installed but needs your carrier's P-CSCF address:
# /etc/imsd.env
PCSCF=<your carrier's P-CSCF IPv6 address>
Find it in a stock-firmware capture or your carrier's IMS documentation, then
systemctl restart imsd. See the
imsd README for the full
variable reference and carrier assumptions.
How it builds
build.sh drives pmbootstrap
with the aports/ overlay in this repository:
device/linux-postmarketos-qcom-milos— the pmaports kernel aport, repointed atcombined-stable(source tarball generated with git-archive; the Forgejo instance serves no source archives) with the exact kernel config the development FP6 runs.modem/imsd— imsd, packaged from source. Itsprovides=81voltdkeeps the conflicting modem-firmware IMS helper off the image (two IMS stacks cannot share one PDN).main/postmarketos-config-nftables— adds the-imsdsubpackage accepting imsd's IPsec-protected SIP ports on the IMS PDN (auto-installed alongside imsd).
Roadmap
- End-to-end pipeline validation (first complete image built 2026-08-08)
- Speaker-audio userspace files (
soc-fairphone-fp6-audio: topology, amp config, UCM — byte-identical to the tested dev-phone set; blob provenance to be settled before this repo goes public) - imsd in the image (pinned to the public 0.3.0 commit; the phone's working call stack incl. callaudioshim and the modem-daemon autostart override ship as packages)
- Nightly schedule once the first dispatched run is green
