Volta Stage 1 here. BMS Monitoring connected fine, so I saved all my settings. The first firmware updating tool I tried would only display in Chinese, so I tried the IAP one. Address it presented was 0x4000, which I I tried. Returned an error message about incorrect location, next pass returned a comms error, and I ended up with the one red LED and rolling green LEDs mentioned. Battery has taken itself offline, so it's clearly unhappy. Any suggestions on recovery, please?
