Yup, it makes sense. I will try with 4 new cells just to make sure if that's not the case

Update on the current situation: After trying a lot, with one of the cables I was able to connect and finished update. Then I reverted to previous firmware and it seemed to work well. Later on I discovered that was not charging the 4 18650 cells, so I try to see on computer what was going on . Couldn't connect it once again, even with same cable (on Linux OS) Decided not to mess more with it, at least until I see if same behavior persists on a windows computer. But at least it works once again. Not a huge problem if i need to charge battery on external charger. One question: If battery is not married , it may happen that they are not balanced and DNA board doesn't charge (or charge so slowly that seems that is not charging)? Thanks a lot for you help

New try, with several cables and the computer doesn't detect the board. Is there a way to force detection after a failed firmware update? Tried on Linux. Unsure if I can be more successful on windows...

Tried with several cables without success. Also no hub. DNA is not detected by PC. Will try on another computer to see if there is no problem with current one. (But I don't think there is)

Yesterday I updated to latest firmware, but it seemed that after doing it, DNA was not recharging. To make sure, decided to go back to previous firmware, but for some weird reason it failed to complete. After that, I cannot get it to connect to escribe. Any solution, or is it bricked?
