Dude! Ive been searching everywhere for someone having this same issue, I thought I was the only one. Im in literally the same exact situation, Im also using virtualbox and I tried updating the firmware and now my dna is bricked, I looked at the usb tab in virtual box and it also reads a bunch of numbers similar to yours. Did you happen to find a solution by any chance? This legit happened to me the day I got my box and I havent even been able to use it yet so Im desperately looking for an answer to this issue. I really hope you figure it out!
