I have messed up, I don't know where to turn. HTC One M8 softbricked in Bootloop.

I have an HTC One m8 that is stuck on Bootloader. It is an unlocked bootloader with S-Off. I had CWM but I installed stock recovery back onto the phone before flashing a stock kernel (I was trying to make the phone look untampered with before I turned it over to my provider), the Kernel came with a sha1 and was from a trusted website and I am 100% sure it was the right compatible Kernel I'm pretty sure I just had a bad flash.
I have tired the following to get the phone past the bootloader:
1. Fastboot USB Mode --> Try to get ADB to recognize the device --> Debugging mode isn't on (obviously) --> ADB can't recognize the device.
2. Use AndroidSDKSlim/ Android SDK tools / Android Utility to remotely turn on Debugging mode (I got nowhere with this)
3. Attempted to use PdaNet to remotely turn on Debugging mode (got nowhere)
4. HTC Sense doesn't even know whats going on
I just need to get TWRP or CWM or litearlly Any recovery installed. That's all I need, I can do everything from there. I can't remotely install a recovery via adb because adb can't recognize my device because I can't turn Debugging mode on because my device is softbricked!!! Gahhhh. I haven't been able to come up with a way to remotely enable debugging mode or to get adb to recognize my device.
Any ideas/comments/suggestions would be heavily appreciated - I've resourced from every relevant thread I could find. Posting here was a last resort I try to fix things on my own but I'm too many days into this with no results please anybody.

ADB won't work while on fastboot mode. ADB only while in recovery or on OS running.
You don't need USB debugging on for fastboot
fastboot devices - see whether your device is listed with serial no.
if yes then run
fastboot flash recovery NameofRecovery.img

Thank you for reply!
I have not been able to get ADB to recognize the device, which is pretty much my whole issue right now. It does not appear under the devices list. If I can just get adb talking with my phone everything else should be easy, I just can't figure out why it's not recognizing it.

When on bootloader/fastboot mode
run command
fastboot devices
not adb devices

Oh.. My..God..
You just saved my life, this whole time I thought fastboot utility in AndroidSDK was just a stripped version of ADB. I'm a moron!

1) Reboot the phone using Power+Vol Up
2) The moment the screen goes dark to reboot and before the white HTC logo screen appears again (Should be around 10 seconds), press the volume down key.... Do not let go of vol down until you see the bootloader screen
3) If the bootloader doesn't appear, you either started pressing Vol Down too late, or let go of it too early. Just do the steps again until you get it right.
4) Once you are in the bootlader, select select fastboot by pressing power key.
5)you can flash either permanent or temporary a TWRP recovery once you are in fastboot.
6)Once you are in recovery mode, you can transfer any custom rom to memory or sd card, then install it from the place you chose.
7) you can flash RUU file at fatboot mode as well.

It can only work in fastboot mode (when off press power+vol.dn).
The fastboot devices command must return your N7's serial number. If not, run it as root/admin and/or install a new driver and fastboot app or use NRT.

Now the phone starts normaly but I can´t start fastboot. When the phone is off and i press Vol down + Power the phone start the android system and the Huawei logo is coming not the fastboot Modus. I can see my phone and the order under Windows but i can not control my phone with the fastboot command. (example: fastboot device. the answere ist searching devices, but it comes no resolution) I loaded the last version of Fastboot, but the problem is the same.

And when you use adb to reboot to bootloader, what happen? Do you have "Minimal adb and fastboot tool" installed?

Sorry for my question, what´s the differents about adb and fastboot tool? I have install the last version of minimal adb and the fastboot tool, also the Windows driver for the phone. Debugging is on. I try to connect my phone about the fastboot terminal. When i try to set the phone into the bootloader mod with the fastboot terminal and the equivalent command, fastboot say´s "searching phone". My phone does not react.

So, you connect your phone, open minimal adb and fastboot too, run "adb devices", you see device id? If yes, run "adb reboot bootloader" . Phone shoult reboot to fastboot mode. Then run "fastboot devices" to see if it is connected properely.

i did it, like you described, but i see not my device id. Only the note "seach device"
Is it possible that TWRP is defect on my device? Is TWRP necessary for fastboot or only for root?

No, you should be able to use adb and fastboot with stock recovery.
After first adb command you shoult approve authorization on your phone.

Here is screenshot from minimal adb...
Phone must be in MTP mode.

And here is phone in fastboot

Many thanks for your help, now I m in my bootloader.
2 problems i had.
1. My daemon was not started correctly, i have not seen my device.
2. I used the wrong command. I started with fastboot, not with the command adb device. I tap „fastboot reboot-bootloader“,but the correct command is “adb reboot-bootlader“
Now i have seen my phone is unlocked, i hope i can root my android 6.

Usually this is a driver issue.
Just download your device driver or update it from device manager on your PC. (Choose update from internet)
Also you need unlocked bootloader to execute this command, use Mi unlock to unlock your Xiaomi device.

Did you really think I'm talking about your PC's drivers?
Search on google for your phone's drivers.
If you're new to flashing then please don't. Only do it if you know what you're doing.

General Bootloop pixel 6 pro

I got bootloop pixel 6 pro
Pc recognize it
Only adb devices and adb fastboot cmd work
Other cmd not work.
Can anyone help me

And always blackscreen. Nothing show or display

Have you enabled USB debugging?
To enable USB debugging you need to enable Developer Options in your phone first. To do this: Go to Settings > About phone > Software info > and then tap the build number about 7 times.
Edit: I can see you have downloaded the Android SDK Platform-Tools on the desktop. Try to run the command under the correct path ( C:\Users\XXXX\Desktop\platform-tools_r33.0.2-windows\platform-tools>

Indeed. I have definitely lost my mind.

Use android flashtool. You can't downgrade on official a13 and I think you have to flash it to both slots or use flashtool

Yes i have bootloader unlock. But totally blackscreen now. Any button do not work.

If ADB and Fastboot still work (and since your bootloader is unlocked), then @fil3s suggestion to use the Android Flash Tool is the best option to try.

Are you using A to C cable?

If fastboot devices works type
Code:
fastboot reboot bootloader
Or use adb sideload

What were you trying to do, and at what point did this happen?
Is your phone recognized as a Android device, or is it showing up as something else?
Does holding down the Power button + Volume Down do anything?
