I have a kindle fire hd 8.9 that is stuck in a boot loop. When i power it on it goes to the (kindle fire) screen. it will stall there for a little bit then restart. then it goes to the same screen again. but this time it has a white light going threw the letters. sometimes it will go to the lock screen. but it wont let me unlock. when it gets stuck on the unlock screen. it will reboot again. i think the battery might be going bad because i can leave it on charge over night and when i unplug it and boot it up. it doesnt stay on as long as it should.
