Since you are not concerned about existing data:
- from TWRP Advanced menu wipe System/Data/Dalvik/Cache partitions
- from TWRP Install menu flash modified FireOS 4.5.5 ROM

That's it. If FireOS can not 'see' the serial number the device many have been black listed by Amazon and/or altered at the hardware level before you acquired it.

Remote possibility the OTA block is creating an issue. You can remove it following the guidance in this and this post. If successful the device will try to download an OTA update but will not be able to apply it as it has dependencies on stock recovery which has been replaced by a custom recovery (TWRP).

So a serial number of zeros indicate a blacklisted kindle? What part has been removed to alter the serial? Then kindle does not appear to have been opened before at all. It looks to be new besides the android os being installed.

I never did an advanced wipe with the initial Fire os flash. I just did the factory wipe is there a difference?

Sorry - original post contained a typo (should have read 'may' vs. 'many'):
...if FireOS can not 'see' the serial number the device may have been black listed by Amazon and/or altered at the hardware level before you acquired it.

It was speculation not a statement of fact.

A 'factory reset' omits the system partition where the ROM resides. While unusual neglecting the wipe the system partition can result in instability and/or unusual behavior of the recently installed ROM. In most cases it simply fails to boot if not an incremental update to the existing ROM.

I have attempted the fire os flash again, unfortunately with the same result. I do notice that even though I executed the wipe step stated as per your instructions, when the Fire os loads I see the couple of pictures I downloaded while on the Nexus rom. It is like it is still using parts of the android rom. Is that standard for this type of flash?

EDIT: I also received the symlinks failed error in the initial install. The tip about changing the mount state of system allowed it to fully install but still no serial.

TWRP wipes preserve the media folder where pictures/videos reside.

I don't have any great ideas around serial number issue. My recommendation is to flash a supported version of Nexus and call it a day. Restore the backed up Nexus build if you want to preserve any content other than pics. Otherwise a 'clean' install is the best option.

Sorry this didn't work out the way you hoped.

I have been poking around and I saw some threads where plain stock roms were offered. I will lurk those threads and see what others have done. I actually found a thread where someone had the same desire as I do with this rom on a HDX. You also commented with help for them ( although the instructions were a little different) and they were successful. I would post that thread but I am not sure how to. I also wonder if I would have made my own thread instead of under this old discontinued thread I would have maybe received help from other contributors that may have an idea of what is happening or if I am doing something wrong.

In any event,
I thank you for all of your assistance. I appreciate it. Cheers.

Sure. Hope you are able to find a solution. Keep in mind the device does not have a stock recovery which limits options for restoring stock FireOS. Good luck; feel free to post questions if you find something that looks promising.

(Don't neglect to consider Amazon Underground w/Nexus which should yield much of the functionality you seek; unfortunately, no Alexa)

Since i unlocked my bootloader 4-5 days ago I've been trying almost every Rom. Nougat based have some problems regarding the WiFi and the Camera seems a bit dark. These are huge deal-breakers for me, since I use the tablet for streaming and Skype. Same goes with the WiFi on the Marshmallow builds. And I tried this Rom, a bit old and now discontinued, but to me is the best. Very stable, while not as buttery smooth as Nougat, it works "fine". No problems with Wifi or Camera or whatsoever. The only major concern is the security issue, not being updated to latest security patches remains open to many vulnerabilities. Another "non-issue" is the fact that many new apps today require at least Lollipop to run, but older apks can be found on the internet.

I am familiar with this ROM having used it as my daily driver for nearly a year. I recommend you try the immediate successor (here) which still receives occational updates. Same KitKat base, same developer/maintainer. It remains the 'go-to' choice for those seeking a fully functional HDX ROM w/o the camera and radio issues you noted. Also works with an unlocked bootloader which is a benefit to some.
