In recovery it says 4.0.1 (TWRP v2.7.1.0)
That means you're on Fire OS 4.5.2, no downgrade below 3.2.8 possible due to rollback protection by Amazon (attempt would brick the device!), no possibility to unlock the bootloader, thus no CM12.1, SlimLP or CM13 for you. Only available options CM11 or Nexus for Safestrap v4.

Concur. But since you received your HDX with Safestrap v4 installed (the SS version was obvious as you were running CM11 which can't be used with lower versions of SS) there is the tininess of chances FireOS could have been upgraded to 4.5.2 while the bootloader remained at/below 3.2.2.3. Special skills are required to do this and such actions are usually revealed by the presence of TWRP recovery which can be accessed via <power>+<vol-up> from a cold start. That's why I suggested you give unlocking a whirl even though the odd are exceptionally long.

BTW - one of my tablets falls into the above category (running FireOS v4 with an unlocked bootloader). Not that I possess such 'special skills'. I shamelessly followed other posters guidance which created the test environment that I was seeking.

tl;dr - If you enjoy pursuing improbable odds give unlocking a whirl.

Good point, indeed unlocking is worth a try. Zero risk, it either works or fails. ;)

Install will not complete?

I've installed safestrap according to the instructions posted above but the status of the safestrap install never changes to installed. I have granted root permission, and I get a popup dialog saying that installation has been completed but the "state" does not change to installed, nor does the safestrap utility appear upon reboot.

Any tips?

Wow - that's an exceptionally old version of Safestrap! Support has long been discontinued. Likely not compatible with the version of FireOS on your device.

Best course of action is to unlock the bootloader so you can install any of the ROMs for this device including CM 14.1 (Nougat based). You can do that now as your device is rooted. No need to upgrade/downgrade FireOS.

Be sure to backup personal content as the device will need to be wiped prior to installing another ROM.

    *** DISCLAIMER ***
    I work on projects that may brick your device. Don't sue me, hate me or try and kill my dog if that happens. I will feel bad the community will feel bad and hopefully we'll find a way to get you going again. But, the very nature of my projects involves a certain amount of risk taken by YOU. And by using the projects that I work on, you've accepted that fact.


    PLEASE PLEASE BE VERY CAREFUL WITH SAFESTRAP!!
    MAKE A BACKUP OF STOCK RIGHT AFTER YOU GET SAFESTRAP INSTALLED SO THAT YOU HAVE SOME KIND OF DISASTER RECOVERY.
    THEN YOU CAN RESTORE IT TO A ROM-SLOT (AFTER YOU MAKE ONE).
    ONLY MODIFY ROM-SLOT FILES. LEAVE YOUR STOCK ROM ALONE!!



    WARNING: THERE IS AN UNKNOWN ISSUE WHERE IF YOU HAVE ENCRYPTION ENABLED AND INSTALL SS IT BOOTLOOPS. IF YOU FIT THIS DESCRIPTION PLEASE STAY AWAY FROM SAFESTRAP FOR NOW.


    UNKNOWN ISSUE: If you try and start Wifi and the device crashes/reboots, try turning on bluetooth prior to enabling wifi and see if that works.



    CURRENT PROJECT STATUS:
    BETA-STABLE


    WHAT IS SAFESTRAP?

    Safestrap is a Bootstrap / Recovery for locked bootloader phones. The goal is to avoid touching your primary system (I'll call this "stock" system) and only flash or make large changes to another place on your phone that Safestrap treats as a "2nd system" (in this case, it's a series of virtual ROM slots located on the internal emmc area: "/sdcard"). Once installed, you will see a "Splashscreen" giving you the option to hit "menu" to enter recovery. The recovery portion of Safestrap is now based on TWRP 2.7.x.x (a touch based recovery) and you can perform .zip installs, backups and restores here. The additional features I've added to TWRP are mostly located under the "Boot Options" menu:
    1. Here you can create virtual ROM-slots for flashing ROMs. These ROM-slots allow for different sizes of /system, /data and /cache partitions. The defaults *SHOULD* be good enough for flashing the stock-based ROMs.

      NOTE: The bigger you make these partition the less room you will have to make other ROM-slots.
    2. You can activate a new ROM-slot by choosing the slot you wish to make active and then selecting the "Activate" button. Once active, you will see the "rom-slot#" up in the top of the screen shown in green. If you make the "stock" ROM active, then you can see it in the top shown in red.
    3. Once a ROM-slot is active, all actions you would normally perform using TWRP are directed to that ROM-slot. For example, "Install" to flash a .zip, backup and restore.
    4. For more information you can read up here:
      http://blog.hash-of-codes.com/how-to-safestrap/

    HOW DO I INSTALL SAFESTRAP?
    1. Requirement: Rooted w/ SuperSU installed
    2. Requirement: Allow APK install from Unknown Sources
    3. Download the Safestrap APK
    4. Find the APK using a Filemanager tool and open it on your device, then click "Install".
    5. (If updating from an existing Safestrap you might be warned that this will over-write the existing installation. Click the "Yes" equivalent to this message.)
    6. Once installed, open up the Safestrap application as you would any other app.
    7. Agree to the disclaimer that you won't try to sue me and hunt me down with a rifle if you manage to break your phone..
    8. Then use the "Install Recovery" button. You should see the current version down in the lower left corner of the window. And the "Status:" should say "Installed" when you're done.
    9. From there you can reboot and you *should* see a new splash screen during the boot up. While this is showing you can enter Safestrap Recovery using the [ menu ] button.
    10. That's it for the installation! Read below for a brief overview of Safestrap Recovery v3.x


    HOW DO I ENTER RECOVERY?

    During each reboot a splashscreen will be displayed showing whether the device is running a rom-slot or on the "Stock ROM".
    Press the button shown on the screen to either enter "RECOVERY" or "CONTINUE" booting.

    HOW DO I UPGRADE SAFESTRAP?
    • Push the APK up to your sdcard.
    • Boot back into the "stock" rom-slot.
    • Go into your old Safestrap app and use the "Uninstall Recovery" button
    • Open an "explorer" of some sort (ESFileExplorer, etc)
    • Browse to where you pushed the APK
    • Click on it and install like normal
    • Once installed, open the APK
    • Grant SU access
    • Use the "Install Recovery" button
    • All set, now you can reboot and re-activate whatever rom-slot you were using

    Here's an amazon-os .zip that can be used on rom-slots for re-flashing the OS -- MUST MATCH STOCK ROM:

    THOR ONLY (HDX 7") 13.3.1.0: Download from goo.im
    md5sum: 24fee10d8c6b0dbf583465baa938e842

    It's the straight Amazon OS:
    • not DeOdexed
    • will not stop OTAs
    • is not rooted
    • the only changes I made, were to strip out the boot.img or modem.img flashing stuff.

    To root, I recommend flashing SuperSU.zip from here and flash in Safestrap to the active rom-slot after flashing the ROM:

    As of version 3.x, Safestrap Recovery is now based on TWRP. For more on TWRP you can visit their website: http://www.teamw.in/

    WARNING: Safestrap is heavily modified to be "Safe" for your device. Do not download TWRP from their website and expect it to work the same way. Also TWRP does not support Safestrap, tho some issues that may come up will be TWRP dependant, please try and contact myself or look on the forums for your device for answers before hunting down TWRP people. They won't be able to help w/ Safestrap specific questions.

    For the purposes of direct user testing I've established a channel on freenode.net IRC: #safestrap
    I'm in the channel mostly all the time, but may not be active for discussion.

    Special Thanks To
    DeesTroy & TeamWin for all their hard work making TWRP such a fantastic recovery

    For those that missed it in the 1st post:

    KNOWN ISSUES WHEN USING ROM-SLOTS (The ROMs are kept on loop device mounted partitions)
    1. In theory you will lose an extra 3-4 percent battery compared to normal usage from 100% to 0% due to the extra read/write work involved when using ROM-slots.
    2. The /data partition is kept separate from the "/sdcard" contents on SS ROMs. This causes the Storage settings to only show the size of the loopback data partition and then it shows "used" which includes the "sdcard" + /data so this can look odd at times (larger usage than partition size). It doesn't have any adverse affects that I know of.
    3. No custom kernel flashing support at this time. Don't try it. It won't work. All kernels need to be signed by Amazon at the moment.

    CHANGELOG:
    • [v3.75-B02]Bugfix rom-slot booting
    • [v3.75-B01]TWRP 2.7.1.0 update + display fix for 13.3.2.3.2/13.3.2.4
    • [v3.72]TWRP 2.7.0.0 update. *** This includes a bugfix for backup time showing correctly ***
    • [v3.72]Raised /data partition size to 16gb
    • [v3.72]Swapped "Reboot" -> "Download" mode to "Reboot" -> "Bootloader" (places you in fastboot mode)
    • [v3.70-B01]Seems like I have a solid fix for the "snow" effect when getting into Safestrap sometimes
    • [v3.70-B01]System partition now matches stock EXACTLY. You can't even change it in the settings due to the way I'm creating it during rom-slot creation. It's not a bug, that's on purpose. That being said, there should be plenty of room in that space to do what we want.
    • [v3.70-B01]Battery % now being displayed correctly in recovery
    • [v3.70-B01]Updated to latest Safestrap sources
    • [v3.65-B01]Initial release for Thor (Kindle HDX 7")

    I just saw the posts regarding the new update woes.

    I may need a day or 2 to debug the update... I'm always nervous when patching Amazon's stuff.

    I also need to d/l the new sources as well.
