To update DJI Mic 2, download the firmware .bin file from DJI's Mic 2 downloads page, connect the receiver (powered off) or a transmitter to a computer by USB-C, copy the file to the root of the device, then disconnect. The receiver updates by itself; a transmitter updates when you power it on. Repeat for each unit, then check the versions on the receiver. There's no app update for Mic 2.
Step by step
- Download the Mic 2 firmware package from DJI's downloads page and unzip it if needed, so you have the .bin file.
- Remove the phone adapter from the receiver if it's attached.
-
Connect one device to the computer with the USB-C cable that came with the kit:
- Receiver: must be powered off when you connect it.
- Transmitter: can be on or off.
- The device shows up as a drive. Copy the .bin file to its root folder, not into a subfolder.
-
Disconnect from the computer.
- The receiver starts updating automatically and its screen shows "updating."
- Power on a transmitter to start its update. Its status LED blinks red and green alternately.
- Repeat for the second transmitter and the receiver.
- On the receiver, swipe down, open Settings, Version to check the receiver and linked transmitter versions.

Update not working?
- Transmitter won't update after power on: DJI says to disable Auto Record on the receiver, or stop the transmitter's internal recording, then try again. A transmitter that starts recording as it powers on won't update.
- Update failed: download the firmware again, restart the device and repeat. A corrupted download is the usual cause.
- Computer doesn't see the device: use a data cable, not charge-only, and try another USB port. The receiver must be off when connected.
- File in the wrong place: it must sit in the root directory.
- Transmitter storage problems: the transmitter only supports FAT32 with an allocation unit of 16 KB or less. If you formatted it on a computer with other settings, format it from the receiver instead (Transmitter Settings, eMMC Storage).
After updating, re-link if needed by placing everything in the charging case. See how to pair DJI Mic 2.
Mic 2 vs Mic Mini updates
DJI Mic Mini updates through the DJI Mimo app on your phone instead of file copying. See Mic Mini firmware update.
