This article will explain what to do if the firmware update on your V3, G3, V2, H4 or ProLx+ fails:
Could you please try the following steps below to resolve the issue:
*Disconnect the device
*Switch the device off
*Manually log out the app (closing the app doesn't log you out)
*Close the app
*Open the app
*Type email address and password to login
*Switch device on
*Re-try the firmware update ensuring that your phone/tablet are in close proximity to each other during the entirety of the update. This will ensure the Bluetooth connection is maintained.
Its also important to make sure the WIFI connection is strong, the Shot Scope device and the phone/tablet are near to each other and that the device isn't interrupted during the process (best to keep it on the Shot Scope app until sync is complete).
