I have a Kindle Fire HD ("7) and to protect some of my pictures that mean a lot to me, I stored them in an app disguised as a calculator. I haven't used my Kindle since last year until now. I went to the app and forgot my pin number and the answer to the security question needed to change the pin. I saw that the app needed to be updated, and I allowed the update which made things worse. What I found out was that to change the pin, I needed to dial a certain number in a phone dial pad which is obviously out of reach and that there is no longer option to answer a security question. Ive tried accessing files through NUMEROUS file explorers and I still have no luck. I am desperate and runnin out of ideas. What do I do now?
