I am unable to get it and I've tried various things to get it to pop up.
First attempt: disable and re-enabling USB Debugging and making sure its connected as a Camera (PTP).
Second attempt: Revoking auth (did not work).
Third attempt: Factory reset with stock firmware Verizon.
Fourth attempt: Reinstalled drivers and restarting ADB with the commands adb kill-server and adb start-server.
I do not know what else to do.

Hello,
First of all, the problem started when Android Kitkat update ota came to my device. After downloading it, my device was not able to verify it, as a result of which, it started downloading the update all over again. It downloaded the update more than 10 times without any success.
So finally I decided to sideload it. I set up everything properly, double checked everything. As I was going to send the update.zip to my tablet through command, the cmd prompt showed me "error: device not found".
I restarted the device, checked the drivers in my computer, even checked whether adb recognized it by commanding "adb devices". It did.
So again I turned it off, entered fastboot mode, But this time before entering recovery, I connected the device (it gave the connecting sound as on Win7). I ran the command "adb devices" and it showed no device at all!
My device is complete stock, unrooted. Usb debugging is turned on and MTP is selected.
Use a toolkit to install\test adb drivers then slide load using it. Some times windows install some crap adb drivers u have to remove them and install the naked drivers.
Toolkit is in development section.
I tested with wugfresh toolkit.
Please ignore my spelling mistakes. English is not my native language.
I have tried multiple troubleshooting tips such as revoking permissions, rebooting the phone and computer and still it shows up as unauthorized. I was on MM and then entered the beta program thinking it would mess with some system files but still adb shows up as unauthorized and no dialog popup shows up on my phone to authorize it. Does anyone know a fix to this situation?
It means it's RSA locked - you need to boot the device and activate USB Debugging, then when prompted on the device, allow the RSA Fingerprint/Key.
Try again afterwards.
I know there are instructions (which I am following) and a similar thread (which doesn't provide a solution). Anyway, I am following the instructions and I'm stuck at the command for detecting fastboot devices. The command window shows nothing, not my serial number or an error message. The Fastboot Protocol option on the tablet's menu just loops back to the same menu. I followed all the instructions (undetailed as they are) correctly, but on the fastboot device step I am stuck. I can't use the CyanogenMod links anymore because they're down. Other websites only give me steps I've already done or don't apply to this.
Basically, I just want to know how to make my PC detect my tablet so I can then wipe and flash the images. I want to downgrade because some apps just don't work correctly with 2.0 and I don't really want to wait for an eventual fix (which may or may not fix all the app issues).
I should mention that I can detect the adb device when it's on normally ( I type adb devices and it shows up). But when i reboot into bootloader and type adb or fastboot devices it isn't detected, and when I try to use fastboot protocol (either before or after connecting) it doesn't do anything.
Had the same issue with fastboot myself. If you are running Windows 10, that could be the problem. The ususal about checking different USB ports etc. also applies.
The drivers are most important. The naked usb drivers seemed to help me the most. Also, if you are going to change the usb drivers you have, reboot between changes. Fastboot can be challenging, but you are on the right tack.
All along ADB was working fine. Now when I enabled it, nothing is detected on the computer. The phone went entirely missing. If I turn it off, the phone comes back. Anyone encountered this?
With ADB turned off
- Phone works in PTP Mode to PC
- Phone works in MTP Mode to PC
- Phone works in MIDI to PC
With ADB turned on
- No phone device detected at all. So I am not even able to change to any of the ADB drivers

What do you mean by "ADB turned off" and "ADB turned on"?
Are you talking about USB Debug?

Yes, USB debug in development menu, even turning it on/off, revoke does not seem to make it work again. it just does not show up on my PC.
Further tests done.
Fastboot works.
Adb works in recovery mode when booted into TWRP 3.0.2-3.
Think I need a way to reset the ADB /usb debug settings within the phone as it looks more and more to be an issue from the phone rather than Windows (v7 x64 sp1)

Not the way I read it. Sounds to me like the exact opposite.... a driver issue with your PC/OS, not the phone. In order for the phone to have adb/fastboot capabilities, the correct drivers need to be installed and actually working on the PC. Without going into detail, you could use a few different tools to REMOVE and install the correct PC drivers. Wug's NRT Toolkit has a very good step-by-step driver configuration guide with verification. I now just use the 15 second ADB installer here on XDA because it is minimalist, and just works. That being said, the NRT has a USB removal tool to rid your system of old USB entries that are likely causing your problem. Give it a whirl.

Shall give it a whirl. Previously it was incorrect driver issue years ago but everything has been working fine on all my Android devices till yesterday when I can't seem to ADB to my 6P. I have the latest USB drivers installed via Android SDK Manager.

Still no go. There's no device at all where I need to change/delete/update driver if I turn on ADB USB mode. Phone is only seen by Windows Device Manager when I turn off USB debugging in developer menu. I still feel it might well be something in the developer menu causing this issue.
I am checking on the folder /data/misc/adb . Permissions is rwxr-s--- . What's the permissions you have for this folder?
Using USBDeview (trying to compare between 2 sets of 6P, both with the December 7.1.1 roms)
6P that works over ADB
Reported VID and PID is 18d1 / 4ee2
6P that does not work over ADB
Reported VID and PID is 18d1 and PID is 4ee1, 4ee5 and 4ee8 depending on which mode (PTP/MTP/MIDI).
Nothing gets reported to be connected at all when I used USBDeview while the 6P that does not connect over ADB USB has USB debugging turned on.
Problem fixed. No idea what was the cause. Hopefully it will help someone else who gets this down the road.
Steps performed
- Clean up SU
- Reboot
- No go
- Reboot to Recovery
- Reflash EFS backup
- Reboot
- No go
- Reboot to recovery
- Clear cache, clear dalvik
- Reboot
- No go
- Reboot to fastboot
- Reflash System, Vendor, Boot
- Reboot
- Works
- Reflash Magisk and PHH
- Still works
Puzzling.
Glad you got it fixed.

Yeah, would have done a full factory reset if all else fails since the hardware was indeed able to connect to my PC properly. Glad the various flashing worked out.
It's weird.
I had my HD8-6G on v5.3.1.0 (now, v5.3.1.1).
I installed the Amazon Fire Drivers that were on the Amazon developer website. But, my Win7x64 PC complained that it still didn't recognize the HD8 device while it was in ADB mode. So, I manually selected the Amazon.com ADB Composite Device for my updated driver. This works ... partially
If I booted the HD8 into "adb sideload" mode, the HD8 was properly recognized, and I was able to install the v5.3.1.1 update. However, the tablet is still not visible when I did an adb devices command. in my ADB / Fastboot shell. I tried running KingoRoot, and the tablet wasn't discovered.
How can I get ADB working properly on Win7x64?

this might be silly, but make sure you have developer mode enabled/adb enabled. also enable unknown sources in security. I would think it should show up when you issue adb devices..how strange.
* also I like to check stay awake.
Those are the very same drivers (fire usb for everything except recovery, and the android ones for the adb composite for recovery) I used and I'm on Windows 7 64 Bit.
* I just put my device in recovery mode and yeah it says android composite adb interface 10/27/2014 1.4.0.0 Amazon Services
hmm..actually it says the same when i reboot

I have all the same settings you list above, but the ADB device isn't being found.
I also don't get prompted for an RSA key. Could that be related? I may have been prompted previously, but I don't think so. This is the first time I think I did any ADB stuff on this tablet.

yes, you must get prompted for RSA key. If you disable usb debugging, then reenable it (with tablet still connected) you should get a prompt and check remember. That definitely is an issue if that never was applied.
* also I like to make sure stay awake is on. In addition, whenever you reboot the tablet, upon rebooting, I like to make sure the screen is unlocked and sometimes you need to quickly unplug it, then replug it back it once it's rebooted for the device to show up in my computer.
