It seems Kingroot (NewKingrootV4.80_C135_B242_office_release_2016_02_ 03_105203.apk)
is working, but you may need to run it a few times before it will root

You may see This Warning
It is not unusual for Anti-malware to give warnings about root programs, because they often use exploits/Trojans in order to gain root access. just click on details, then visit this unsafe site.

Looks like the HD 8/10 Does not have a nice Fastboot screen, like the Fire 7 in
Seems it's just a black screen.
There should be a few different ways to get to Fastboot mode

From Power off: Hold Volume Down and power on.

From Power Off: Hold Volume UP and power on, it should boot to Recovery
From Recovery: select Boot Bootloader, bootloader has Fastboot mode enabled

From Rom; Use ADB command
adb reboot-bootloader
or
adb reboot recovery


I don't think the modified boot.img is going to work as it is now
Creating a bootable custom recovery may be the best option for the HD 8/10
like ggow did here http://forum.xda-developers.com/ama...ecovery-cyanogen-recovery-2015-11-04-t3240726



Original Post:

Looking for Testers for a Possible Root method
Using the same method of creating a Boot.img that makes the /system rw for the 2015 7 in Fire.
@csolanol and @diegocr have created a batch file, with a modified boot.img for the HD 8/10.
There is some risk that this method will not work, Amazon may have done something different in the 8 and 10 models.
If the boot.img does not work, the tester may have to re install the firmware via adb sideload, or this could brick the device, although that is unlikely.
just post in this thread, if you are willing to test, the batch file is already uploaded to dropbox.

Tom, thanks for sending this.
Since you're sending this via PM, I'm assuming you'd prefer me to ask questions via PM, rather than the forum. If you'd prefer this on the forum, I'm happy to move the conversation there.

Running Win 10 64bit, New Kindle Fire HD 8" 5th Edition, connected directly via USB (not USB hub).

I'm running into the following.

When it should go into Fastbook mode, the device just shows a black screen even though the Device Manager appears to show the Fire in ABD device mode.


Booting device...
downloading 'boot.img'...
OKAY [ 0.219s]
booting...
FAILED (Status read failed (Too many links))
finished. total time: 0.502s

//It didn't reboot so I manually report it

//lots of errors similar to the following

mkdir failed for /system/app/SuperSU, Read-only file system/app/SuperSUunable to open /system/app/SuperSU: No such file or directory
chcon: could not label / ...

//looks like the files weren't written
//I'm addred drivers and tried to make sure they lined up with what you'd written for both Composite & fastboot mode.
Replying back in the thread, just didn't want to make the boot.img available if it causes issues,
but easier for csolanol , diegocr and others to reply in the thread.
The script may not work with the HD 8"
If it tried flashing the boot.img anywhere other than fastboot mode, the rest will also fail.
May need to do the step manually, till we figure out somethings.
From power off, hold volume Up, and power on, does it boot to fastboot mode?
Are you familiar with using adb/fasboot commands?

Fastboot mode only shows black screen

Environment: Kindle Fire 8 HD (5th Ed), Surface Pro 3, Win 10 Pro 64bit, connected directly (not through USB hub)

When I run the batch file fastboot appears to reboot the Fire into bootloader (I think). At that point the Fire's screen appears black. Nothing on the screen.
Windows Device manager shows a change in the device from "Android Composite ADB interface to (something ABD)




I press a key & get the following Error. Multiple attempts each produce the same error message (only the times vary)
Booting device...

OKAY [ 0.219s]

FAILED (Status read failed (Too many links))

The bat command doesn't reboot the kindle and I have to do it manually. At the login I press another key and get the following

mkdir failed for /system/app/SuperSU, Read-only file system/app/SuperSU unable to open /system/app/SuperSU: No such file or directory
chcon: could not label / ...​

I've managed sporadically (power & volume down ) to get into recovery
wiping cache hung with some error messages
factory reset proceeded but was followed with cache related error messages
Now its not finishing booting.

Based on the video there should be something on the screen when the Fire goes into fastboot and that never happened on my device.

Re: abd commands. I've only used them occasionally.

An no, Vol Up & Power doesn't boot into fastboot.
Currently it shows "fire" with a color swipe and just sits there and doesn't appear to finish booting.

No, that's more recent.

I ran the batch, got the error message I posted. Rebooted the Fire. Re-ran the batch. Same error message. Rebooted the Fire. ran the batch, same error. Manually make sure the drivers are right. Try continuing and get the write error messages, reboot the Fire. Stumble on Recovery, try to wipe cache. It hung. (I think this is was really messed me up) reboot. And a few more attempts with the batch. Tried wiping the cache again. Rebooted got to recovery, factory reset. Saw error messages related to cache folder.

error wiping cache is not good,
Do you have adb.exe and fastboot.exe files?

if not download [TOOL] [WINDOWS] ADB, Fastboot and Drivers - 15 seconds ADB Installer v1.4.3 by Snoop05
run the adb-setup-1.4.3.exe
follow the on screen prompts. you can allow install drivers, and adb global
it should end by opening a command prompt like

Code:
Microsoft Windows [Version 10.0.10240]
(c) 2015 Microsoft Corporation. All rights reserved.
C:\Program Files (x86)\Minimal ADB and Fastboot>
connect tablet to pc
type/paste in command prompt window
Code:
fastboot -i 0x1949 getvar product
should get something like this back
Code:
Memphis

Thank you for the detailed help.

adb installed
ran command fastboot -i 0x1949 getvar product
result
< waiting for device >
Kindle still stuck trying to boot but the device manager switched from showing Fire as under Other Device to Android Composite ADB Interface and its showing up under Portable Devices as Fire but with a yellow ! icon.
