The radio is placed in bootloader mode by switching on the radio with the enter key held down. The status message ‘Bootloader’ will be displayed on the screen.
The radio can then be connected to a PC via a USB data cable. The status message will change to ‘USB Plugged’, and the PC should display two external drives connected. The first is for the radio flash memory, and the second is the content of the SD card or eMMC.
This mode is used for reading and writing files to SD card or eMMC and/or the radio flash memory.
This mode can also be used to connect to Ethos Suite for updating the radio. Please refer to Bootloader Mode in the Ethos Suite section.
