3.4.7 Format SD cards
SD cards must be formatted after being formatted in other devices. Tap the ‘Format SD
cards’ bar to format all unit cameras’ SD cards.
Note:
Formatting SD cards permanently deletes any data they contain. Be sure to copy any files
you want to keep to a computer before proceeding.
We offer an option to format the controller’s SD card. If you switch on this button, the SD
card in the controller will also be formatted, but this is not recommended in common use
because it will cause the loss of log files in the controller. Logs are important because they
provide information on how users operate the camera and the system running state.
Developers check the logs to locate problems.
3.4.8 Factory Reset
With this setting, you can reset all cameras to default settings. This also resets the shot
counter.

Please follow the steps below to update firmware:
1) Power off YI HALO and unplug the microSD card from the controller.
2) Copy the ‘firmware_master.bin’ and ‘firmware_slave.bin’ files to controller’s MicroSD
card root directory.
3) Insert the microSD card back to the controller.
4) Confirm that microSD cards in all unit cameras are available.
5) Power on the rig.
6) Navigate the setting menu, tap the ‘Firmware Update’ bar, confirm to update firmware
on a pop-up, then the firmware updating will start.
Note: This process takes about 30 minutes normally.
