USB Firmware Updating

If you are unable to update your firmware over the Internet you may also update locally using a microUSB cable. To access the microUSB port you must open your BAC case by extracting the 4 screws on top and carefully removing the lid. Escape Room Techs will provide the appropriate firmware upon request. Once you have received this firmware, download the utility using the link below and follow the instructions.
