Thank you for allowing me to assist you, my name is Joe and I will be happy to assist you with your concern today.
How can I further assist you with your kindle or ipod?
Is the kindle you are referring to that you came back to and something did not work the same as the fire you are also referring to? Or are those two different kindles that you have?
What do you mean by "optimum" key?
My apologies if I am confused on anything.
When you were previously working with someone on your kindle fire did that happen to be amazon kindle support? I say this because I do not show any other questions from you in regards ***** ***** kindle fire.
If you were speaking to amazon kindle support please contact them back directly at http://www.amazon.com/gp/help/customer/display.html?nodeId=200127470
You can also call them directly at: 1-***-***-****
If you would like to continue with me I will need to know exactly which kindle fire version you have and then I will have you try a soft reset.
We do not work hands on with customers devices and thus why I think you may have been dealing with kindle directly.
