USB not detecting HL7688 after firmware update

Hello Klin2,

I was not able to update the software as the model is different. I am working on HL7688 not HL75xx. I have attached the screenshot of the error message for your information.

Is there a fix for the HL7688 version which I could test to see if the problem is fixed?
fw_download_error

I would like to ask you, is there a workaround with the existing build A2.15.1 which we could perform to fix the problem?

Thanks
Harish K
