Please help to get out of fastboot/Logo screen!! topic

I was on CM 11. I wanted to restart fresh to I flashed
to KF 8.4.6 which worked fine. I then (this starts the
trouble) tried to reset device (remove personal data) from within kindle screens

1) rebooted to red screen
2) finally got into fastboot
3) tried this:

fastboot -i 0x1949 flash bootloader kfhd8-u-boot-prod-8.1.4.bin

fastboot -i 0x1949 flash boot kfhd8-freedom-boot-8.4.3.img

fastboot -i 0x1949 flash recovery kfhd8-twrp-2.6.0.0-recovery.img

fastboot -i 0x1949 reboot

4) it reboots and stays at yellow kindle fire logo

5) then I tried just this but same result:

fastboot -i 0x1949 flash bootloader kfhd8-u-boot-prod-8.1.4.bin

Any Ideas?? Please? I am not upset that I cant use it...I'm upset that I cant fix it!
