Root cause: openpilot v0.11.2 (pushed to
release-tizi2026-10-22 02:04 UTC) movedsystem/hardware/tici/all-partitions.jsontoopenpilot/common/hardware/comma/all-partitions.json, so therelease_tizimanifest URL insrc/config.jsnow returns 404.release-ticiandrelease-micistill serve the old path.Fix: update
release_tiziinsrc/config.jstohttps://raw.githubusercontent.com/commaai/openpilot/release-tizi/openpilot/common/hardware/comma/all-partitions.jsonVerified: I ran 7dddd54 locally with only that change and recovered a 3X. All 32 image URLs in the new manifest resolve.
Heads-up on a separate issue after flashing: that manifest installs AGNOS 19.4, while v0.11.2 requires 19.9 (
AGNOS_VERSIONinlaunch_env.sh). On 19.4 the bundled setup crashes at startup withModuleNotFoundError: No module named 'serial'(fromsystem/hardware/tici/lpa.py, same as openpilot#38620), so the device sits on the comma logo. Installing pyserial into/usr/local/venvover adb got setup running; after that, openpilot's AGNOS 19.9 update started (in progress, will report back).all-partitions.jsononrelease-tizilooks like it wasn't regenerated for 19.9.mcowell commentedon Oct 22, 2026
Follow-up: the AGNOS 19.9 update completed and stock openpilot v0.11.2 runs fine on the 3X. PR with the URL fix: #239.
