[Q] Get blue fire, but pressing volume up goes to fastboot

view story

http://forum.xda-developers.com – After following the instructions and rooting the KFHD7 as well as installing the 2nd bootloader and TWRP, I see the blue fire and press the volume up, but instead of going to TWRP, it goes to fastboot. If I don't press the volume up, the KFHD7 boots into the rooted stock kindle image. I tried reflashing TWRP but no change in behavior. Anyone seen this and know the cause? (HowTos)
