My HTC M8 Stuck at ONE Logo once restarted. No Recovery, No DWNLD mode available.

I've seen already this thread suggested by XDA thread locator.
https://forum.xda-developers.com/htc-one-m8/help/verizon-htc-one-m8-stuck-htc-logo-t3163088

But I'd try to explain as simple as possible the whole situation which happened hours ago.
Don't know what happened but my mothers phone went off and restarted with htc one logo on it and nothing else later.
Power button itself doesnt work and is not responding.
Configuration PWR + VOL UP gives me restart but no recovery mode, giving me sound effect of restarting phone and ONE logo on it without any other reaction whatsoever.
PWR + VOL DWN zero reaction
PWR + VOL UP & DOWN pressed together restarting the phone and then gives me HTC ONE LOGO and nothing else.

when Phone is plugged in to the computer and I'm forcing the phone to restart it shows me new Device on the computer as a CD Driver every time.
So I think there is still hope to get this guy back to life.
It's running on custom rom but unknown version because it was purchased as a refurb from ebay 2 years ago and it was running just fine utill this very day.
I'm absolutely noob with flashing twrping etc so please ELI5 if possible, any type of help will be much appreciated.

Thanks in advance.

Hey, I had this same problem a couple of days ago. Here's what I did to get the phone into fastboot, from where you can install a recovery, factory reset etc.

1. Hold the power button + vol up button for about 10-20 seconds. This should shut down the phone.
2. Hold the power button + vol down button to restart the phone back into fastboot.

If you can get into fastboot, there are plenty of guides which can help you flash a twrp image. If you want me to give you some instructions on that just reply and let me know. Good luck!

Note that this phone doesn't have download mode (as some other Android devices do); nor is there a button combo to go directly to recovery. But you can almost certainly still get to bootloader, and from there boot recovery. In the current condition, you can get to bootloader by:

1) Hold Power+ vol up (as you have been) to restart the phone.
2) Once the screen goes dark (signaling it is about to reboot) let go of the buttons, and only hold vol down
3) Don't let go of vol down until the bootloader screen appears.
4) If the above sequence fails, its virtually always because the user just didn't get the timing right (either started pressing vol down too late, or let go too early). Just repeat steps 1-3 until you get to bootloader.

Once in bootloader, try to reflash the ROM, or restore a TWRP backup (if you have one). Spontaneously stuck on HTC logo screen is often a result of the OS/ROM becoming corrupt or otherwise damaged, and flashing/restoring the ROM will often fix it.

Thanks @redpoint73 I've managed to get to the preinstalled recovery.
Sadly reflashing/factory reset failed few times due corrupted files.
I'm ok with the fact that I lost the data on the phone since most of it was stored on the cloud.
Now I need ROM to flash on the phone thru recovery but I don't know which one would you reccomend.
It's my mom's phone so basically reliabilty and robustness over flashing lights and numerous unnecessary functions.
Version of android doesn't really matter.

Thanks again for help so far.
Can I put the rom I'm about to flash on external SD Card or I have to transfer it thru computer to the phone?
TWRP might be extra helpful or the recovery it's functions are just fine?

I'd need to know more about the phone in order to give any suggestions.

With the phone connected to computer, boot into fastboot mode, and (assuming you have fastboot setup on your computer) do the command: fastboot getvar all

Then post the results (delete IMEI and serial number before posting).

Also, what version TWRP (if that is the recovery installed)?

Can I put the rom I'm about to flash on external SD Card or I have to transfer it thru computer to the phone?

You will be able to flash a ROM from the SD card, if using TWRP.

TWRP might be extra helpful or the recovery it's functions are just fine?

Not sure what is being asked here (can't quite understand). Are you saying that another recovery besides TWRP is presently installed?

@redpoint73 I don't have TWRP but this...
Maybe pictures will justify the real situation.
I don't have the fastboot preinstalled on computer. (yet)
I wouldn't mind link to the pack with "must have" to complete the process

You have what is called the "stock recovery" or official HTC recovery.

You can't flash anything but OTA updates, or other official (HTC) signed zips with this. You need a "custom" recovery like TWRP in order to flash things like custom ROMs. So I'm curious what you meant before when you posted:

Thanks [MENTION=660462]Sadly reflashing/factory reset failed few times due corrupted files.

What exactly were you trying to "reflash", what were the exact steps, and the results (specific error messages, etc.).

I did the factory reset but it didn't help still stucking at ONE logo like posted initially. So this is basically the situation right now. I was able to get to recovery but nothing else.

Okay, so you're confusing the terms. Factory reset doesn't flash/reflash anything (flash meaning to install some firmware or software to the device). The only thing that factory reset does is wipe user data.

At this point, I'd suggest the best/easiest course of action in the current conditions (stock recovery, locked bootloader) would be to run the RUU intended for your device. Your device is the AT&T version, so the RUU can be found at the bottom of the page (and instructions on how to install): http://www.htc.com/us/support/htc-one-m8-att/news/

RUU is a complete factory image. You download to a PC (PC required, won't work on Mac or Linux) connect the phone (booted into bootloader-fastboot mode) then just run the RUU, and it will do the rest.

I'm confidant this will get the phone up and running. Your mom may not like all the AT&T branding and apps, if it wasn't there before, and AT&T is not her carrier (one of the main reasons for these devices to have custom ROM - to remove carrier branding). But we can cross that bridge (if need be), after we get the phone working.

Installed Software, downloaded RUU from website provided, turned phone into fastboot before installing RUU.
Something started happening with the phone during installation but installation itself cant be finished, it's an endless process of update, phone is already plugged 3rd hour or so to the computer but the update status remain the same.

Should I try different approach?

It just gets stuck sometimes. Just kill the process, and start the RUU again. It will probably work fine on the next try. It's a bit scary, as it says not to stop the process or disconnect the phone while it's running. But if it gets stuck like this, there isn't anything else you can do.

Good News, it's working. But it's bloated to the bones. How I can get rid of the carrier unnecessary software?
I was to afraid to kill the process during update to avoid scenario of bricking my phone completely.
But It's working!
