Fujifilm X-A1
Part of the protocol is documented (e.g. telemetry, not control).
Fujihack documents its RTOS API and patches its firmware 1.50 with a USB debugger (experimental).
Get started
One known way to put open firmware or software on this device, easiest first. Each one links to the project's own instructions.
- Back up your data and settings (and the stock firmware, when the guide says how).
- Check the exact model, hardware revision and firmware version against the guide: a close model may not work.
- Charge the battery or use a stable power supply; do not unplug during the install.

- Firmware
- Built against Fujifilm firmware 1.50.
A patched firmware update is built from Fujifilm's own and installed from the card like an official update; the USB debugger then runs code on the camera. Experimental: a bad patch can brick the camera and its boot ROM recovery is not reverse engineered. Flashing an unmodified official update restores it if the camera still boots.

Verification
Not verified. A "verified on hardware" badge requires a replayable test (hardware-replay) run on a real device with a stated firmware version.
