FireOS 4.5.5.1 can be rooted and supports SafeStrap v4. This is a fairly new development. Prior version of FireOS above 4.5.2 could not be rooted and/or did not support Safestrap. Amazon doled out a gift with the 4.5.5.1 update.
Prior to 4.5.5.1 it was the only path to getting to a rootable version of FireOS v4 (rollback to 3.2.8 then upgrade to 4.5.2).
Huge thanks, that time I have asked your help I did not expect doing the “homework” will be so complicated. Few years ago I found it impossible to carry out all this steps without making any mistakes but here I am again.
Last week I found my tablet in my mom’s house as she carried on using it until its crashes got really annoying. After charging overnight it could turn it on, remove Safestrap, and xposed framework, and I got TWRP 2.8.7 back, made a backup of everything just in case, then i started researching if there is anything new that would make my job easier. Found a comment of yours somewhere where you expained step-by-step how to unlock the bootloader on 13.3.1.0, updated TWRP to 3.1.1.-1, then followed ggow’s instructions to flash AOSP Extended with gapps and magisk.
Everything worked well for the first try so my tablet is up running again, following questions will be asked in relevant threads
)
Glad you were able to work through the procedures and revitalize your HDX. A tip-of-the hat in your direction as it speaks to personal discipline and tenacity. Suspect several learnings took place along the way that will prove beneficial downstream. Enjoy your revitalized device!

Introduction:
The main question is: Why we wanna root this tablet and install SAFESTRAP?The purpose of this tutorial is to make the tablet ready to save the stock rom with SAFESTRAP and get a rooted device which is able to get googleplay store and an alternative launcher, maybe if you want i can add a section which contains how to SAFESTRAP the stock rom right and how you flash your first custom rom to your device. Let me know if you want this?!
Ok here we go

Thanks to Faznx92 for your awesome KFHDX ToolKit!!!
Thanks to ggow for your awesome HDX Nexus ROM v2.0.1!!!
Thanks to Hashcode for your awesome SAFESTRAP!!!
Thanks to 058515471 for your Tutorial!!!9I started downloading and installing everything, and while doing that the Kindle won't let me save the edited build.prop using es file explorer or build prop editor. I can't seem to change permissions of the file either. Bummer. Should be interesting upgrading to 13.3.2.6 to rollback. Hoping to not brick the device, but its on its last legs anyways.
This is where my downgrade didn't go as smoothly as planned.
Got this from the command prompt.
Unable to chmod /system/build.prop: Read-only file systemCode:Adb shell chmod 644 /system/build.prop
OTA?
Go into wireless and forget your wireless settings passwords. If the Kindle can't connect to wireless how is it going to download an update? I guess turn wireless off to be extra cautious. Disabling and renabling OTA updates through KDFX seems to mess up the check device thing to update the internal sd card bin files for the steps below.
Remove Safestrap
Boot into stock rom slot.
Go into safestrap and uninstall recovery.
After this I reran KDFX to towelroot and put su on, just in case.
Update to 13.2.2.5 for the Eventual Downgrade tp 13.3.1.0
http://forum.xda-developers.com/kindle-fire-hdx/general/update-1314-4-1-1-probably-sangria-t2901813
Had to factory reset, before the device would even see any bin file. Ended up using the 13.3.2.5 bin file. Would not update to 13.3.2.6. The device would say its not valid and delete the file. You weren't kidding that this is not straightforward.
https://s3.amazonaws.com/kindle-fire-updates/update-kindle-13.3.2.5_user_325001120.bin
Downgrade to 13.3.1.0
After I got 13.3.2.5 on the device I used the install.bat from here
http://forum.xda-developers.com/showthread.php?t=2782159
The final step of following the instructions of putting 13.3.1.0 on internal card and rebooting did not work. I had to yet again factory reset, then put update-kindle-1X.3.1.0_user_310079820.bin back onto the internal sdcard. And then finally got to 13.3.1.0.
No matter what I did to upgrade and downgrade these bin files they wouldn't take unless I factory reset each time.
Install TWRP here
Make sure you have root through towelroot and su, using KFHDX+ToolKit+v0.95 .

TWRP Flashable .3.2.3 Bootloader Upgrade here
http://forum.xda-developers.com/kin...p-flashable-3-2-3-bootloader-upgrade-t3025504
Create Unlock File
Once that was done I went through the steps for the unlock file here

Fastboot on windows 8.1 x64 is something special.
With the device plugged in, uninstall the adb driver from device manager and reboot.
This video helps explain how to install the fastboot drivers, sort of, https://www.youtube.com/watch?v=afrvSGiMAtk. Or follow text below.
Mouse over to top right of windows screen for the charms menu.
Click settings at the bottom.
Change PC Settings
Update & Recover
Recovery
Advanced Startup
Restart Now
At this menu click troubleshoot
Advanced options
Startup Settings
Restart
Then type 7 to force driver install without signatures.
Fastboot Into the Kindle
From there boot the Kindle into fastboot. I held down power/up volume/down volume like another thread suggests. Or go into TWRP->Reboot->Bootloader
Download this driver and put the unzipped folder somewhere.
http://forum.xda-developers.com/showpost.php?p=59268023&postcount=8
When TWRP says fastboot, plug the USB cord from the motherboard port (not external ports) to the Kindle. In device manager fastboot hopefully shows up and forces the install of the downloaded drivers. I had to uninstall whatever yellow triangle drivers were showing up, until fastboot would finally show. It will give a red box saying are you sure. yes I am sure, and now you have working fastboot drivers on Win 8.1 x64.
Install Minimal ADB and Fastboot
At this point, I was sick and tired of going to the Android Studio directory and used minimal ADB and Fastboot instead.
http://forum.xda-developers.com/showthread.php?t=2317790
Finally unlock the bootloader
Copy the unlocked file into wherever your fastboot.exe is located. And type below line by line.
(Makes sure a device shows up)Code:fastboot -i 0x1949 devices
(replace the filename with the file you created from cuberHDX.py, once done should show successful in green letters)Code:fastboot -i 0x1949 flash unlock 0xFILLIDSERIAL.unlock
(cross fingers)Code:fastboot -i 0x1949 reboot
Install CM12
http://forum.xda-developers.com/kin...ent/rom-cm-12-unofficial-apollo-thor-t3050199
Put cm12 rom into a directory (I make a roms folder on the internal card), reboot into TWRP, install cm12 rom.
Install gapps from here
http://d-h.st/users/dhacker29/?fld_id=27426#files
I used this latest version, gapps-lp-20150211-signed.zip
Huge thanks to everyone who has put their 2 cents into what to do from the various threads all over this forum.3Major success!
Unlocked the bootloader using Linux (Python already installed, just had to install some plugin for it to do its job), flashed TWRP, didn't see it upon restart - remembered it's not like SafeStrap, appearing every time. Rebooted into recovery via ADB, backed up 3.1.0, flashed 3.2.3, and eventually installed Nexus 4.
I have it working, but I just realized that I don't have a Titanium Backup of my apps, though I do have a SafeStrap backup of the earlier Nexus ROM.
Would it be safe to restore the SafeStrap backup via TWRP to grab a copy of all my apps, then re-flash Nexus 4, so I can restore those?
I want to thank @ggow, @Cl4ncy, and @Davey126 for getting me this far!3
Don't factory reset - at least not yet. Path forward:
- remove Xposed, Safestrap and any other app that has hooks into the system (basically anything that requires root access). Retain Fire OS 13.3.x, root and SuperSu.
- download 3.2.5 here; print upgrade instructions
- disconnect from wifi and remove all wifi profiles
- disable/remove OTA blocker (if installed)
- upgrade to 3.2.5 using previously referenced instructions
- reroot using HDX toolkit (optionally block OTA with the same tool if you plan to enable wifi; must be unblocked for next step)
- downgrade to 13.1.0 (here) following instructions in lower part of post. DO NOT MESS WITH BUILD.PROP!
- install twrp (here). Disregard bootloader unlock and 3.2.3.2 firmware guidance for now
- upgrade boot loader to 3.2.3.2 (here)
- flash Nexus 2.0.5 or CM11 (you can't get to CM12 without additional steps)
This is just a rough outline; you need to do your homework for each step. Read the relevant threads and take note of cautions and gotchas. Be aware there is significant risk associated with some steps that can yield a hard brick. Plan your actions and don't take any step without an understanding of expected and unexpected outcomes. Post questions in the forums if you are unsure.
A more expansive version of the above along with bootloader unlock guidance can be found here. Good luck!
