f) reboot, press UP + power to boot into TWRP

At this step my tablet rebooted into fast boot. My computer couldn't detect the device so I shut the tablet down. Now it won't turn on.

Is there anything I can do?

I've tried both Motorola and Amazon drivers

Single dash: "-i"

If that doesn't work drop the "-i 0x1949" as it's normally not needed.

Edit: I got it to work by using a different computer.

However on my second Fire HDX 7 going into "adb reboot bootloader" has been powered off and hasn't turned on since.

From what I can tell I've bricked 2/3 Kindle Fire HDXs. This is insane...

I got a bit further than that but now I got Error native opening file 0: The operation completed succesfully when doing dd of=\\?\Device\Harddisk1\Partition18 if=twrp_cubed.img commands

I got further to the next step.

dd of=\\?\Device\HarddiskX\Partition6 if=aboot_vuln.mbn
dd of=\\?\Device\HarddiskX\Partition18 if=twrp_cubed.img

all the diskindex I got were 1 so all I did was copy exactly the above like so

dd of=\\?\Device\Harddisk1\Partition6 if=aboot_vuln.mbn
dd of=\\?\Device\Harddisk1\Partition18 if=twrp_cubed.img

and I get Error native opening file: 0 the operation completed succesfully

Upon trying to reboot into TWRP I keep the black screen. The tablet seems to still be online and in bulk mode however
