I lost control of my RedBear DUO . I cannot engage it anymore into the 4 SETUP/RESET steps. If I press both buttons, and release reset , the RGB LED goes solid white, then it goes to solid blue, then blinks blue. I tried to setup the WiFi, then I get the cyan/red LED flashing all over. That's it!
The dfu-util says no device in DFU mode available. I cannot engaged it into that mode.
Then I tried to update the firmware using the 1MB drive, I move 4 files: part1 & 2, the Wifi, and web file, then I ran the Burn bootloader in the IDE, now I get this message: Flash algorithm write command FAILURE written to the drive.
The DUO really lost its mind.
