I'm having the same trouble. Did you solve it?

Hi polemax

i fixed it by holding the reset button.

I tried this method initially though it didnt work. what you need to do is get a slim and firm object to press and be able to hold down on the reset button. you will hear a click when you press it, then you hold it down for 10 seconds.

i hope you fix your problem and remember, for me pressing the reset button does not work - you need to to firmly hold it down for around 10 seconds.

all the best

Thanks for help

I have the same problem! But reset factory doesn't solve it :/
