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!
I have TWRP up and running holy crap thank you so so so so much, you are seriously a life saver.

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.

Use the Menu in bootloader mode to reboot to bootloader while it is waiting for device. That should get flash-all. bat to just run.

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.
Please can you help me. What can i do? Many thanks for your help!

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.

New Razer Phone (1) stuck on download mode.

I bought a refurbished Razer phone one from the official razer eBay page, and it's stuck on download mode. I haven't tried flashing anything, I haven't even ever been to the home screen. What can I do to fix this?

Get the Google USB Driver and make sure your Razer phone is installed with these drivers
https://developer.android.com/studio/run/win-usb
Get Android SDK Platform Tools for latest ADB and fastboot tool
https://developer.android.com/studio/releases/platform-tools
Open command prompt to that folder and run these commands
fastboot flashing unlock
fastboot flashing unlock_critical
fastboot set_active a
from what i've gathered from other threads with similar problems, that's the jist of it...

It says "Waiting for any device" the problem is that it's not recognized by the computer.

Thank you ! Same problem. This is halp! after first run, works. Question, can I block it now? and how please... fastboot flashashing lock ?

Now I can block back? fastboot flashashing lock ?

Hello. Same problem. ( I bought a refurbished Razer phone one from the official razer eBay page, and it's stuck on download mode. I haven't tried flashing anything). It helped me. Now I can block back? fastboot flashashing lock ? Please, sorry my english...

EDIT: The links did not copy paste appropriately. I fixed them now.
These are all posts from various places in this thread:

"Find the driver here:
https://dl-ssl.google.com/android/repository/latest_usb_driver_windows.zip
unzip the files/folder to a location you will remember
Follow the instructions below, point the windows driver update to the .inf file in that folder then driver will install. Make sure you have the latest Android platform tools, the link is also in the PDF below.
https://s3.amazonaws.com/cheryl-fac...stall_Android_Fastboot_Drivers_on_Windows.pdf
open a command prompt from within the Android sdk folder while the phone is still in download mode (phone stays and reboots to download mode through each process below making the process fairly easy)
type: fastboot devices
your phone should show up once drivers are installed correctly
type: fastboot flashing unlock
use the phone vol + - and power to select yes
phone should stay in download mode
type: fastboot flashing unlock_critical
use vol + - and power to select yes
phone should stay in download mode
Download the firmware image below or if you want to try the following command type: fastboot set_active a && fastboot reboot
to see if the phone boots, not sure if all the phones have Android installed. One poster below seems to and also seems to have his bootloader unlocked. This won't be the case for everyone. If phone does not boot continue downloading the firmware to install it
https://s3.amazonaws.com/cheryl-factory-images/cheryl-o-global-6033.zip
unzip all the files and put them in the android sdk folder, from the same command prompt if you're on Windows
type: flash_all.bat
For Mac type: flash_all.sh
Will take a few minutes but firmware will install. These instructions are for RFD members that do not either 1) want the hassle of RMA or 2) take a chance at voiding the warranty (any phone flashing via adb is frowned upon by Razer)"
------------------------------------------------------------
"Yes. Reverse the locking procedure. Put phone back into Download mode (from power off, press and hold Vol up and then plug phone into computer) then issue fastboot commands to lock boatloader starting with critical."
------------------------------------------------------------
"if you have a ryzen pc and getting some error while unlocking... dont plug the phone in at the beginning... type the command when it says [waiting for device] then plug it in ... also dont forget to unlock critical right after"

Now I can block back? fastboot flashashing lock ?

it helped, now it is loaded; but after each reboot it writes, the phone is unlocked and that it is unsafe. can it be blocked back, is it safe that everything continues to work? please write what commands to enter?

Repeat the unlock commands using lock instead of unlock but in reverse order so:
fastboot flashing lock_critical
fastboot flashing lock
again you must place the phone in download mode (powered off...hold volume down key down...plug in) between each command and follow the onscreen instructions.

I used to enter these commands , the instructions were only after 1
I did not turn off the phone and the question on the screen was only after the first command. I probably entered only 1 command <if it was necessary to disconnect phone? ... thank you for help.

Sudo.
If ur using linux - run it with sudo. always run fastboot with sudo
