CODE: Not connected


Trying to update my Code 50 to the new firmware but it says "Not Connected" to the computer. I've tried everything that is on the troubleshooting page, I have an Mac pro and tried with both Crome and Opera. Last time I updated it was not any problems. 

I have following versions on the amp (see this when I'm starting the amp in the bootloader mode)
BL: 0.6
MCU: 1.3
DSP: 1.1

Do you have any more tips on how to update the firmware to the new?

Hi! I have the same problem. Bought my CODE 50 yesterday and spent the whole night trying to connect it by USB, But there is no way.
It says "Please connect your CODE amplifier using a USB cable", I used two different cables but none of them worked.
Need some help, thanks!

Hi Manuel,

Can you confirm what you are connecting too, to do the update.

Hi Manuel,

Thank you for the details, there are no error logs our end, I would suggest checking the usb drivers on your PC, if they are not picking up the connection.

Hi Andreas,

Thank you for getting in contact, have you tried another cable to see if this is the issue, I have sent it over to the team to look into.
