I tried to update to 3.9.9. As a result, my BeatBuddy won’t turn on.
I downloaded the files to a PC. Connected the BB to the PC via USB. Copied the files to the BB SD card. The BB flashed Upgrading Firmware. I disconnected the USB (BB was still connected to power, no I did not pull the power cord out). The screen went black. BB will not turn on.
