First of all, make sure you’ve input device password correctly — it’s your OpenSprinkler’s device password (it’s opendoor if you have never changed it), not your WiFi password or anything else.
Second, if update failed, give it another try. Sometimes the transfer may be interrupted due to WiFi signal issue etc. Try a few more times and see if it succeeds.
