Of course, I downloaded Ver2.45 sample firmware and updated it immediately. But nothing improved.From what I remember the issue is solved by the "unofficial" V2.45 firmware that is not on the website but supplied directly to the customer.
Think there are a few people on this forum who had this issue and got the V2.45 firmware from John.
There was no support after that and I returned the D30Pro after all.
The D30 Pro firmware on Topping's HP is still Ver2.44 from before and there is no change after that.
