RE: USB Upgrade issues

Did you also connect the power, when you press and hold the redial button?

Kind regards,
Frank.

I am not an employee of Yealink.
Dutch is my native language, not English. Apologies for my imperfect grammar.
Please do not send unsolicited PM messages. I will not answer them.
