Hi! I bought a herelink more than 1 year ago and when updating the CONTROL firmware, the serial is being refused. I found that I need to contact the dealer to get a new serial in pattern “####-####-####-####” in order to upgrade. The update has already been done, but I’m stopped at the screen that asks for the serial and unfortunately my dealer hasn’t responded so far, can anyone help me about this?
please provide the device serial number
Settings > About Phone > Status > Serial Number
Thank you for your help.
