I am sorry Alex didn’t get back to you. I hope he got your email.
We have seen a consistent issue with the kit installations. I think perhaps the instructions to upgrade the Bridge first are not very clear because people seem to miss this step until it’s too late. In any case, a DAC is needed to update the Bridge firmware. I will try and get Alex to answer you on Monday. You can get the Bridge rescue firmware and take care of it - although to A&T’s point - you must have a DAC to do this.
