Another Can't boot after unlock and twrp install

I'll try to make this brief and to the point as I realize how many people come here seeking help.
I've rooted many android devices (my first was an htc incredible) so I'm not exactly "new" per say, but don't really fully understand what I'm doing either long story short.
Got my nexus 7 today, tested some things with the screen when I first got it (just playing videos to see how bright it is)
I Followed a video suggested (somewhere) on the forums (video here (but I can't post urls))
-Sat down, got the usb drivers from here - Can't post link
-got adb fast boot tools - can't post link
-Downloaded SuperSU
-Enabled usb debugging in settings
-Booted into recovery
-Updated Driver when prompted
-allowed usb debugging after entering adb devices command
-used adb reboot bootloader command
-used fastboot oem unlock command (worked succesfully)
-used flash recovery openrecovery-twrp-2.6.0.0-flo (personally I think it didn't flash correctly because I don't know how to explain issues I will detail below
- (unless this is where I went wrong) rebooted to get into os so I could place supersu.zip on internal storage for rooting
- sticks at glowing X
ADB won't recognize the nexus 7 in recovery or bootloader
Windows only sees the nexus 7 as either

I've tried wiping from recovery, it fails.
I DO seem to be able to get adb to recognize the tablet when it is in recovery mode now.

I've tried reflashing Twrp, still can't wipe, Is it possible for me to just install kitkat from recovry straight from adb or fastboot? It's been a while but I was thinking if I could just reset the os it might work. I have razor-krt16s-factory-7235eb0d.tgz ready to go I just don't know how to put it on the tablet without an sd card to transfer with
I have also installed Wugs Nexus Root Kit but since I have no idea what build of 4.3 my n7 is running...it really isn't doing me any good -_-.
any help would be appreciated, I'm stumped but will be continuing to dig for answers.
Thanks

[Q] Kind of Bricked My Device (Nexus 7 3G)

So what happened was that I tried to install the update of paranoid android's latest version. Since TWRP cannot install it, I used CWM. All my back-ups are in TWRP so I had no chance to restore. Now, my device is stuck in recovery mode. I could enter the fast boot mode. Now I don't know what to do since all guides in restoration say that I have to enable USB debugging, something impossible in a device which cannot enter the interface.
Please help. Thanks

You only need fastboot access so you don't need usb debugging, but you will need the Android SDK.
1) Read this guide.
2) Download the latest factory image from here.
3) Follow the guide from the "Flashing the Factory Image" section's 4th point.
Good luck.

reinstall stock ROM on a soft-bricked (?) Nexus 7 2013 - recovery mode failed

I have a Nexus 7 (2013) which was recently upgraded to Lollipop 5.0.1 from KitKat 4.4.4 via OTA, and it randomly restarted and is now stuck on the Google screen. I can get to the bootloader via the hardware buttons, and it's recognized as an Android device when plugged in via USB (USB debugging and developer options were previously enabled.) However, I can't get to recovery mode to wipe the device, as it simply gets stuck on the Google screen again. Fastboot commands are nonresponsive in fastboot mode, and I assume I need to get to recovery mode to run any fastboot/ADB commands.
Note that my Nexus 7 is entirely stock and has not been rooted or altered in any way, aside from OTA updates.
I can wipe and reinstall KitKat once I get my Nexus device to function in recovery mode, but I need to get there first!

Sir,
Please wait until mods will move this thread to the device specific forum.

Stand by
Until then read this thread: [GUIDE] Flashing a Factory Image with fastboot / return to stock
Good luck

Nexus 7 2012 Hard brick after downgrade?

Hello guys! I come now to the point ..
I bought the Nexus 7 WiFi only for in-car use .. When I received it, had the CyanogenMod 12.1! so I decided to install the rom AUTODROID 1.2! I downloaded the ROM, install the .zip TWRP (latest version) and so I had a bootloop .. Restore backup done previously with TWRP! I am looking online and I see that making the dowgrade from lollipop kitkat, first I had to flash the rom original KitKat!
ADB and fastboot drain, drain the "ROM" (the right one for the Nexus 7 2012 wifi), reboot into fastboot mode and do the command .bat adb .. but something went wrong
"Fastboot.exe stopped working"
From here you have begun problems: recovery is no longer accessible, and restart I always brought to the fastboot mode! I had the bright idea to turn off the tablet ...
From here .. Black screen, fastboot mode is not available, recovery is not available, so I can not even give commands ADB .. When the connection to the tablet pc, windows gives me input connection, but during the driver installation I give me the error "Unknown Device" ..
I do not know what to do .. Can you help?

You could try using the nexus root toolkit ( wugfresh NRT ) to fix your nexus

I just try it! but the program don't recognize the nexus via adb!
My computer "see" the nexus with the APX driver, but I can't do nothing.. no fastboot, no recovery e no adb! Just black screen

Stuck in bootloop after failed update.

Please help!!!
I tried to update my rooted Nexus 6P to 8.0.0 (OPR5.170623.011, Nov 2017) using the Flashfire app and something went wrong!!! The phone is now stuck in bootloop and will not get past the 4 google coloured dots. I can boot the phone into the bootloader and then get into TWRP recovery from there but thats pretty much it.
I hoped I would be able to fix it by flashing the system image, bootloader etc using adb and fastboot but have had no luck. I have tried on both a PC and a Mac and neither seem to recognize the device. When using the commands "adb devices" or "fastboot devices" nothing shows up and when I try to flash anything it says "waiting for any device" yet when the phone is off it signals that it is charging from the laptop.
I have updated my rooted 6P multiple times before using both Flashfire and adb/fastboot from both a PC and a Mac and have never had problems before this. I have run out of ideas to try so any help would be greatly appreciated but I fear I might have bricked my beloved Nexus 6P.

Weird. You should at least have fastboot when in bootloader mode, and MTP with TWRP. In bootloader mode, plug the device into your PC. The device is not detected at all? Have you tried wiping cache/dalvik? MTP not working in TWRP?

If you can boot into recovery then your device is not bricked. Make sure the adb and fastboot binaries on your computer are completely up to date. I'm pretty sure Google updated them for Oreo. You will need to flash the full stock image with flash-all.bat command when you get your computer to recognize your phone. Updating from Nougat to Oreo using Flashfire or Flashify is a bad idea because you are dealing with something way more extensive than an OTA update.
