Please note that here have been two versions of TC2TR hardware with Bootloader V3.x. These versions are identifiable by their serial number and both require a different version of firmware. This firmware is for all TC2TR units with serial numbers BELOW 8323095. Serial numbers ABOVE 8323095 only work correctly with version 5.13. ( goto Legacy firmware TC2TR )

KissBox CPU versions are related to their boot-loader version and marked accordingly on the serial number label. A boot-loader version being V3.x for example indicates a V3 type CPU. When uploading firmware to a KissBox the Editor firmware wizard will also inform you of the Boot-loader/CPU version of the connected KissBox.

It is important to check that you load the right firmware in the right box. The TC2TR should only be loaded with Firmware specifically meant for it. Using a wrong firmware file will lead to erratic behaviour. Accidentally loading an incorrect type of firmware will not physically damage the KissBox, it will however stop functioning. If this has happened, it can be solved in most cases by re-loading the correct firmware.


The new V3.2 bootloader hardware is not compatible with older bootloader V3.0 firmwares. The installation of the wrong firmwares on V3.2 hardware will “brick” the unit. It will have to be returned to the factory for repair.
