[Help] Completely Messed my Phone Up lol...

Hello,
These past two days have not been a good day for my phone lol. Some background:
BEFORE:
I had a 4.4.4 Custom ROM [Forgot the name...]
TWRP: 2.5.0.2
AFTER:
I clean flashed http://forum.xda-developers.com/gal...m-cyanogenmod-12-0-nightlies-verizon-t2998057
I cleared cache + Dalvik after the flash and it asked me if I wanted to fix root (From what I read before, you're never supposed to press Fix, rather you're supposed to prses Do not Fix and you'll still keep your root.
However, I accidentally pressed Fix Root and Now I lost my root. The ROM I flashed is glitchy because from what I read is because I have TWRP 2.5.0.2.
Now I'm stuck on this ROM, I have no idea how to upgrade to the latest TWRP and don't know how to get my root back . [Can't get TWRP Manager because I don't have Google apps (I tried flashing the GAPPS by Paranoid but it keeps crashing because I think it's the outdated TWRP)]. I tried to download TWRP manager on my phone via another site, but it doesn't install on my phone for some weird reason.
Thank you,
Jerry
Download, install and run the towelroot.apk file. This will root your phone, takes about 2 minutes

bootloop after super su update

i was trying to get my z3v all set up for my wife to use, the usb port went out a couple months ago and i upgraded to the galaxy s8+, so we bought a wireless charger for the z3v so she could use it. anyway super su prompted me to update which i did then i updated the file hosts on adaway, i rebooted after this and now the phone is stuck in a bootloop.
it seems like once every 8-10 loops it boots farther in showing more of the boot animation which i find odd. i can only get into the stock recovery which has limited options. would doing a factory reset from stock recovery help? i had exposed installed if that makes a difference.
You must have flashed wrong about recovery or boot partition... Bootlops generally happen when boot or recovery partitions were messed. Flash twrp again. If possible, find a rooted twrp zip.

How to completely restore main firmware from crdroid ?

So I rooted my tablet today in the morning, and has been discovering new stuff with root all the day it's night now. And I tried custom root (crdroid),
And it was pain in the ass. 1- wiped everything using the advanced tool (data,cache 1, cache 2, system) and used the
(Tabs3_oreo_forced+encryption_disabler).zip flashed it then flashed SuperSU, booted into it, explored for 2 hours noticed no SuperSU, wanted to go back to download mode but serial image shoed on screen and in the middle was: {Press home key to go into download mode} did that then got to twrp and wanted to install supersu but couldn't mount data, tried million combination of magisk the disabler and supersu but it's either: run vanilla crdroid, (without google service and stuff and couldn't download thanks to the loop) get data unmounted, get stuck on the screen saying: (tab s3 by Samsung blah blah) so I'm hoping to get back to the original firmware, which I'm downloading it now (region: iraq) but after I get back to original I'm gonna root it (because it worked flawlessly then, I can do that) but any help on how to install main firmware, should I just twrp the install ? Or can you guys give another way ?

Hi thanks for the reply it has been a really long loooooong time since i checked xda on my account, and I'm happy to say I'm now a master in custom roms and rooting, currently trying to port s-pen functions, and fix the damn camera problem with custom roms on this particular device. Thanks again.
