My name is***** am sorry to hear that you are having this issue.
I will be glad to assist you with this.
To unlock and reset your Kindle, Paperwhite or Fire:
1. On a Kindle Fire (any model) attempt to enter a password—any string of characters will do—five times in a row. After the fifth failed attempt, you’ll be prompted to reset the Fire without having to go through the menus as described above.
2. On a regular Kindle, Kindle Touch or Paperwhite, reset your Kindle by entering “111222777″ as the parental controls / screen lock password.
did that work for you?
