Default [Q] Stuck on (kindle fire) screen

Hello, I just got a Kindle Fire HD 8.9 from my sister. She asked me to try to fix it for her. Its all stock from factory. never been rooted. the only thing i can get it to do it boot to the ( KINDLE FIRE) logo. its sits there for a few minutes and restarts. someones if i let it sit long enough it will go to the unlock screen. but when i try to swipe to unlock it does nothing. I can get it into fastboot. but from there i can't get it to do anything. when i try to restore from the SR tool i get a error. FAILED <remote: artition>. any help would be great.
