I am in need of assistance. Just got my freedrum starter kit a week ago and have only used it one time and i am experiencing the endless red light problem which ive noticed some other people on here have experienced . Basically my sensors remain red, when i try to reboot (holding button 7s) it flashes and turns yellow. When i open the app, i try to update as directed and when i try to update in the sensorware app i recieve the following error REMOTE DFU INVALID CRC ERROR. i have tried letting the battery die and then rebooting yet the issue persists I suspect these sensors are broken. Please assist me with replacing them or resolving this issue.
