[SuperSU] Andydg22:
Hello everybody! I am new to xda so I hope I'm in the right place. Rooting a KF (2013) has proved to be quite challenging for me, also because I am dumb :). Anyway I have tried to install the 'Permanent Root with Superuser' via Kindle Fire Utility 0.9.8 but I am not able to. I know that I am missing something but I am too dumb to understand what. I need the help of experts. So, I have run Kindle Fire Utility 0.9.8 and I got this:

I have connected my KF Soho to the laptop through the factory cable and I have selected 1, and I got this:

2 Fastboot (4002)
3 Recovery (5001)
0 Recheck ADB/Fastboot Mode

ADB Status: Online
Boot Status: Unknown

Please make a selection or hit ENTER to return:

Then I have selected 1 and I got this:

***********************************************

The system cannot find the drive specified.
failed to copy 'files\nbmode' to '/data/local/nbmode': Permission denied
Unable to open /data/local/nbmode: No such file or directory
/system/bin/sh: /data/local/nbmode: not found

The kindle has been told to reboot in Normal Mode.

Press any key to continue . . .

If I select fastboot instead, I get this:

***********************************************
* Activating Fastboot (4002) *
***********************************************

failed to copy 'files\fbmode' to '/data/local/fbmode': Permission denied
Unable to open /data/local/fbmode: No such file or directory

The kindle has been told to reboot in Fastboot Mode.

Press any key to continue . . .

In both cases my tablet reboots but checking with 'Root Analyzer' I can see that it is not rooted.

I have also tried rooting with Root_with_Restore_by_Bin4ry_v30 choosing the 1st option but I get this:

======================================================================

Device type:

2) Special (for example: Sony Tablet S, Medion Lifetab)
3) New Xperia Root by Goroh_kun (Xperia Z, Xperia V [JellyBean] ...)

x) Unroot

Now unlock your device and confirm the restore operation.
Please look at your device and click RESTORE!
If all is successful i will tell you, if not this shell will run forever.
Running ...

At this point, my kindle fire displays a screen where I have to choose between 'Do not restore' and 'Restore my data' and I chose 'Restore my data' but my tablet does not reboot at all and the runme.bat file keeps running forever. I have also tried not to press anything at all on the 'Do not restore/Restore my data' screen and I get this:

Successful, going to reboot your device in 10 seconds!
Waiting for device to show up again....
Going to copy files to it's place
mount: permission denied (are you root?)
You can close all open command-prompts now!
After reboot all is done! Have fun!

Press any key to continue . . .

My tablet actually reboots but checking with Root Analyzer I still see the message 'No, your device is not rooted'. What should I do? :'( Ask me all the questions you need and I'll do my best to answer them. Also, please keep in mind that I am not technical therefore explain me things as you would explain them to a quite smart baby :) Thanks for your help! :)

Also, I'll write here more details about my device if it is of any help for you guys:
