Hello
I buyed a  JY-HQS02N4G-2 on the official store
Joying say to me:
"Hi dear friend, thanks for your order, But I am sorry to tell you that this new interface have not stock in EU warehouse"

I paid for this new interface but......

"Hi dear friend , we can send the old interface  to you from EU warehouse . if you didn't like that's interface , I can send you  a firmware to exchange to  new interface" like this

Ok I accept. BUT....
I received an very old interface the same at photo
