DJI Matrice 400 Firmware Update v17.02.12.04 Boosts Line Inspection

DJI released a new firmware update for the Matrice 400 on 28 May 2026, bringing aircraft firmware v17.02.12.04. The release sharpens the platform for utility and energy inspection teams, with new Line Inspection support on the Zenmuse H30 Series and a smarter Power Line Follow mode for LiDAR payloads. Here is a clear breakdown of what changed and how to install it.

What The 28 May 2026 Matrice 400 Firmware Update Includes

This DJI Matrice 400 firmware update is a focused, inspection led release rather than a broad overhaul. DJI has concentrated on the workflows that matter most to power line, pylon and infrastructure crews, building on the steady stream of Matrice 400 updates seen across early 2026.

Three headline changes stand out. Line Inspection is now available when flying the Zenmuse H30 Series. Pilots can adjust the gimbal pitch angle during a Line Inspection run. And Power Line Follow can now be set to continue after a signal loss when paired with the Zenmuse L2 or L3.

Each of these targets a real pain point in long range linear asset surveys, where flights track miles of conductor and the operator needs the aircraft to behave predictably even when the picture is busy or the link drops.

Line Inspection Comes To The Zenmuse H30 Series

The standout addition is native Line Inspection for the Zenmuse H30 Series. The H30 and H30T are DJI's multi sensor inspection cameras, combining wide, zoom, thermal and laser range finding in one payload. Adding Line Inspection means the Matrice 400 can now lock onto a conductor or structure and fly a consistent, repeatable path while the H30 captures the detail.

DJI has also added gimbal pitch control during Line Inspection. That sounds minor, but it gives the pilot the freedom to tilt the camera up or down mid task to follow sagging spans, catch fittings on the underside of a crossarm, or hold a clean angle on insulators without breaking the automated run. The result is fewer repeat passes and more usable frames per sortie.

For asset owners and inspection contractors, this tightens the gap between data capture and reporting. Cleaner, more consistent imagery feeds straight into defect detection and condition reports.

Power Line Follow Now Continues After Signal Loss

The second meaningful change applies to LiDAR work. When the Matrice 400 carries a Zenmuse L2 or the newer L3, you can now configure Power Line Follow to keep running if the control signal is lost.

Long power line corridors often pass through terrain that interrupts the radio link, such as valleys, dense tree lines and built up areas. Previously a dropout could pause or end an automated follow. With this setting enabled, the aircraft maintains the task and keeps gathering point cloud data along the line, which protects the continuity of the survey and reduces wasted flights.

This is a practical reliability gain for beyond visual line of sight and long corridor operations, where every interrupted run costs time and money.

Firmware Versions In This Release

Alongside the aircraft firmware v17.02.12.04, the 28 May 2026 package updates the wider Matrice 400 ecosystem. Key versions include:

• Remote Controller firmware v01.64.08.14
• DJI Pilot 2 App for Android v17.2.0.24
• Zenmuse L3 v17.02.00.02
• Zenmuse H30 and H30T v10.05.02.01
• TB100 Intelligent Flight Battery v16.00.00.63

DJI also notes that the BS100 Intelligent Battery Station firmware carries a battery update within the same release, so plan a little extra time if your kit includes the battery station.

How To Update Your DJI Matrice 400

Updating is handled through the DJI Pilot 2 app and DJI Assistant 2 (Enterprise Series). The built in DJI Pilot 2 app updates alongside the remote controller firmware, so keep the controller charged and connected throughout.

One important step applies to payloads. When using the Zenmuse L2, P1 or H30 Series with the Matrice 400, update the payload firmware first using an SD card before updating the aircraft. Skipping this can leave the camera and aircraft out of step. Always confirm every component, the aircraft, controller, payload and app, sits on the latest version before flying a live job.

FAQs

What is the latest DJI Matrice 400 firmware version?

The latest aircraft firmware is v17.02.12.04, released on 28 May 2026. It ships with remote controller firmware v01.64.08.14 and DJI Pilot 2 for Android v17.2.0.24.

How do I update DJI Matrice 400 firmware?

Update through the DJI Pilot 2 app and DJI Assistant 2 (Enterprise Series). For the Zenmuse L2, P1 and H30 Series payloads, update the payload firmware first using an SD card, then update the aircraft and remote controller.

What does Line Inspection on the Zenmuse H30 do?

Line Inspection lets the Matrice 400 fly a consistent, repeatable path along a conductor or structure while the Zenmuse H30 Series captures the detail. This update also adds gimbal pitch adjustment during the run for better framing.

Does the DJI Matrice 400 support the Zenmuse L3?

Yes. The Matrice 400 supports the Zenmuse L3 LiDAR payload, and this firmware adds the option for Power Line Follow to continue after signal loss when flying with the L2 or L3.

Final Thoughts

The 28 May 2026 firmware update keeps the Matrice 400 firmly aimed at professional inspection work. Line Inspection on the Zenmuse H30 Series, mid task gimbal control and a more resilient Power Line Follow mode all add up to fewer repeat flights and cleaner data for energy and utility teams. It is a worthwhile update for any crew running linear asset surveys.
