Firmware flashing and option activation is performed using the UBT utility which is located in the same archive with CARBUS Analyzer. The interface is in a special update mode—Boot mode.

When connected to the computer, the interface is in the operating mode – the main mode.

Switches to Boot mode

Connect the interface to the computer

Run the UBT utility

Select a port and click Connect. You can see: Interface isn’t in BOOT mode.
The UBT form shows the firmware version and board version. Note that the Hardware parameter should be: CH-OBD.M02 modified Boot (see screenshot above). If you do not see modified Boot, your interface has a previous boot loader version and you must install a jumper on the XP1 connector to boot.

Click Start Bootloader. After 4 seconds, the interface will enter the Boot mode. If the interface does not boot into Boot mode, you may have previously downloaded a firmware that does not support automatic boot transition, in which case you will need to install a jumper between pins 3 and 4 of the XP1 connector on the interface board and then connect it to the computer, In this case, after pressing Connect, the interface immediately appears in the Boot mode.


To flashing the firmware, click the REFLASH button and select the required firmware file. The current firmware files are located in the UBT\Firmware files folder. Once the file is selected, the firmware process begins. It must wait for it to end.

After the firmware flashing is successful, you must press the Disconnect button and reconnect the USB interface cable.

If you have installed a jumper to go to the Boot mode, you must disconnect the interface from the computer and remove the jumper !
