[Root] Amazon Fire HD 8 & 10 (5th Gen 2015)

I think you should reinstall the firmware
Download
update-kindle-32.5.2.2_user_522054520.bin or newer
place the bin file in the same location as the command prompt has listed when using adb commands
reboot tablet to recovery mode>select apply update from ADB
check device manager tablet should be listed as sideload or adb composite interface
if not drivers are not correct
from command prompt

adb sideload update-kindle-32.5.2.2_user_522054520.bin

install may take 10mins or so,
it should reboot to recovery options again
wipe cache, wait for it to finish,
select reboot, may take a few minutes to boot

What is the correct button combination to get the fire into recovery? I've stumbled on it a few times but not in a repeatable fashion. Right now the device is still just showing "fire" with the yellow line passing across the word but makes no progress.

If that is not working could try adb command

adb reboot recovery

Thanks, was able to get it back running

Fire: from powered off
Hold Vol Up & Power
Booted into recovery

PC: Driver appeared wrong
updated Windows Device Manager drivers
Was under "Other"
selected Andoird ADB Interface

Fire: selected "adb sideload" something
error messages
E:Can't mount /cache/recovery/dropbox_last_lmsg
can't open...
E:failed to mount /cache (Invalid argument)

Fire: In recovery
selected wipe cache
This time it worked
sideloaded update-kindle-32.5.2.2_user_522054520.bin
Attempted to go to fastboot but the screen just stayed black (left it for 90 minutes and it was still black)

Attempted rebooting
unplug USB, finished rebooting appears fine.

PC: Attempted batch file again

PC: on the Device Manager fire appears under

It is very possible that fastboot mode on the HD 8, doesn't say fastboot on it.
don't use the batch file, till you can manually run some fastboot commands successfully
try

fastboot -i 0x1949 getvar product

product: THEBES
finished. total time: 0.031s

product: THEBES
finished. total time: 0.031s

Ok that should be correct other than I thought the 8in was Memphis and 10in was THEBES

 

[sd_shadow]

ok when you run the batch file, it asks you to press enter once the device is in fastboot mode, right?

 

[gt7599a]

Yes, should I go forward?

Yes, boot the device normally (stock rom)
open device manager and wait till it shows up as adb composite interface
run the batch
when it detect the tablet it should show two things on the batch window
serial # and something like Fire or tablet
something like this

A000asdfghjkl122346.................Fire

If you could post the first 4 of the serial and the device name, that would be helpful
then you can press enter
watch device manager for it to show up again
In fastboot mode device manager it should be adb interface (without composite)
if it takes longer than 2 mins, disconnect usb, and wait a few secs (or try a different port) then reconnect usb
once you see it in device manager press enter
you should see

sending...
success
writing...
success

if you see failed try to remember what failed
but it may go by fast
if it doesn't reboot by itself, reply here, and post what you saw
if it reboot back to stock rom, recheck device manager before continuing
press enter when you see it in device manager
same steps for the other reboots

Tried and it gave the same error I had originally.

Booting device...
downloading 'boot.img'...
OKAY [ 0.219s]

Sorry, I tried it with the batch file before I saw you directions. Let me try again & I'll post

Same error as post #32 above with slightly variations in the times

Fire doesn't really reboot. Device manager doesn't detect it.

Fire doesn't really reboot. Device manager detects it but as "Unknown USB device (Device Descriptor Request Failed)"

You are going to need to sideload firmware again
this boot.img doesn't seem to work

 

[gt7599a]

if I press and hold power it reboots fine. Or at least appears fine.

@csolanol and @diegocr
any ideas?
Did you use ?
update-kindle-32.5.2.2_user_522054520.bin
or
update-kindle-32.5.2.2_user_522053720.bin

 

[gt7599a]

I went with update-kindle-32.5.2.2_user_522054520.bin

 

[sd_shadow]

I went with update-kindle-32.5.2.2_user_522054520.bin

yep, good to know
do you know which version you were on before you started?

but i was asking about which version was used to create the boot.img

 

[gt7599a]

I didn't write down the version, but the device updated (on it's own) 3 different times when I first got it and during the earlier attempts & reboots

Hello, used boot.bin from update-kindle-32.5.2.2_user_522053720.bin

Can use bootimg.exe to extract and build it, here is with 7'' original boot.bin, ignore this .bin
Can only extract and rebuild boot.bin and lost signature, if unsigned boots by fastboot, bootloader don't check signature.

No idea why gives links error, at modified init.rc don't create any new symlink

What about the recovery posted in the Fire tread?
Will it work with the HD10? If so why it will not be possible to root it that way?
