Your DJI Smart Controller 2 refuses to update past firmware version V01.00.0820, repeatedly displaying Error Code 0x02 during every attempt. Whether you’re using home Wi-Fi, a phone hotspot, or DJI Assistant 2 on your computer, the process stalls at the same point before failing. This specific DJI Smart Controller 2 not updating issue traps many pilots in a frustrating cycle of failed attempts. Before you waste more time troubleshooting network settings or reinstalling software, understand this critical reality: Your update failure likely stems from a fundamental controller-aircraft mismatch rather than a simple technical glitch.
If you own a Mavic 2 Pro, you’re attempting the impossible—this drone only works with the original Smart Controller, not the newer Smart Controller 2 designed for Mavic 3 series aircraft. This incompatibility causes the persistent Error Code 0x02 across all update methods. In this guide, you’ll discover how to definitively identify your controller model, decode what Error 0x02 truly means for your setup, and learn whether your device can ever successfully update with your current drone.
Verify Your DJI Smart Controller Model Before Updating
Stop all update attempts immediately—this single verification step could save you hours of wasted effort. Many pilots mistakenly purchase the newer Smart Controller 2 (RC Pro) for their Mavic 2 Pro, unaware of critical compatibility differences. Your controller’s model number determines whether update failures are fixable or indicate an incompatible purchase.
Original vs. Smart Controller 2 Physical Identification
Examine these key differences to avoid further frustration:
– Original Smart Controller (CP.MA.00000219.01): Works exclusively with Mavic 2 Pro/Zoom. Features a distinct grey linking button and matte finish.
– Smart Controller 2/RC Pro: Designed for Mavic 3 series and newer. Has a black linking button, brighter display, and “RC Pro” labeling.
– Critical indicator: If your controller links directly to Mavic 3 aircraft but shows compatibility errors with Mavic 2 Pro, you have the wrong model.
Quick Model Verification Checklist
Follow these steps to confirm your controller’s identity:
1. Power off the controller completely and remove any connected devices
2. Locate the label on the back panel or inside the battery compartment
3. Match the model number against DJI’s official specifications:
– Original Smart Controller: CP.MA.00000219.01
– Smart Controller 2: RC-N1 or RC Pro model numbers
4. Cross-reference packaging labels for “Mavic 2 Pro compatible” wording
Decode Error Code 0x02 Update Failures
This specific error consistently appears across all update methods because it signals a core compatibility conflict, not temporary network issues. Understanding its pattern reveals why standard troubleshooting fails.
What Error 0x02 Actually Indicates
While DJI hasn’t published official documentation for this code, its universal appearance points to three critical failure scenarios:
– Firmware package rejection: The controller recognizes the update as incompatible with its hardware
– Hardware identification mismatch: Your Mavic 2 Pro identifies the Smart Controller 2 as an unauthorized device
– Update pathway corruption: The drone-controller communication protocol fails during firmware verification
Error 0x02 Failure Sequence
Notice this consistent pattern during every update attempt:
1. Download phase: Progress bar advances normally (85-95% completion)
2. Verification stall: Progress freezes at 98-99% as the system checks hardware compatibility
3. Critical failure: Error 0x02 appears within seconds as the controller rejects the update
4. Automatic rollback: Device reverts to previous firmware version (V01.00.0820)
Why Wi-Fi Updates Fail for DJI Smart Controller 2
Home networks and phone hotspots aren’t the culprits—Error 0x02 appears regardless of connection strength because the failure occurs during compatibility verification, not data transfer.
Phone Hotspot Limitations Explained
Using your smartphone introduces unnecessary complications:
– Data cap interference: Firmware files exceed 500MB, triggering mobile data restrictions
– Connection timeouts: Phone sleep modes interrupt the 10-15 minute verification process
– Network switching: Automatic Wi-Fi/cellular handoffs break the continuous connection required
Network Troubleshooting That Won’t Help
Avoid wasting time on these common but ineffective fixes:
– Switching between 2.4GHz/5GHz bands (the error occurs post-download)
– Disabling firewalls or antivirus (DJI servers resolve correctly)
– Resetting routers (the failure happens during local verification)
DJI Assistant 2 Update Failures: Connection Breakdown
Computer-based updates fail because DJI Assistant 2 cannot establish the required drone-controller communication chain when hardware is incompatible.
Why Mavic 2 Pro Creates Update Blockers
Attempting updates through your aircraft creates a fragile three-step pathway:
1. Computer connects to Mavic 2 Pro via USB cable
2. Drone attempts to relay firmware to controller via radio link
3. Controller rejects the update during hardware handshake
Any mismatch at step 3 triggers Error 0x02, regardless of software version.
Critical DJI Assistant 2 Limitations
When these symptoms appear, compatibility issues are confirmed:
– Greyed-out options: Factory reset and firmware menus remain inaccessible
– Device misidentification: Software may show “Unknown Device” instead of controller model
– Firmware mismatch warnings: Assistant serves V01.01.0076 (Mavic 3 firmware) to incompatible hardware
Confirm Mavic 2 Pro Compatibility Immediately
This isn’t just about updating—it’s about whether your controller can ever work with your drone. The Mavic 2 Pro’s hardware limitations make compatibility non-negotiable.
Official DJI Compatibility Matrix

| Smart Controller 2 (RC Pro) | ❌ Fails | ✅ Works | ✅ Works |
Compatibility Verification Protocol
Follow this sequence before proceeding:
1. Power on Mavic 2 Pro with controller disconnected
2. Check aircraft status lights for normal operation
3. Attempt controller pairing:
– ✅ Compatible: Grey linking button illuminates solid white
– ❌ Incompatible: Button remains unresponsive or flashes red
4. Consult DJI Fly app for specific error messages during pairing
Alternative Firmware Update Methods That Might Work
Only attempt these if compatibility verification confirms your controller matches your drone. For genuine Smart Controller 2 units with Mavic 3 series, these approaches bypass Error 0x02.
SD Card Firmware Installation
When direct updates fail, try this manual method:
1. Download firmware file V01.01.0076 from DJI’s official site
2. Format microSD card to FAT32 (not exFAT)
3. Rename file to RC_PRO_FW_V01010076.bin
4. Insert card into controller’s SD slot
5. Power on while holding Fn + C1 buttons for 5 seconds
6. Navigate to System > Firmware Update in hidden menu
