Hello,
I've tried researching this issue but nobody seems to have the same issue that I do.
Background: I've had my Pixel C with the stock OS (Android 8.1.0) and everything else stock. It is not rooted, and the bootloader is not unlocked as far as I know. I bought it on eBay like 4 years ago. Never had an issue with anything. I have connected it with multiple USB A to C cables (to rule cables out) on multiple Windows computers (to rule out specific computer issue) that I've used with ADB on my OnePlus 7 Pro before, so all the platform tools should be good (ruled out that the platform tools were the issue).
Issue: I cannot boot this thing into fastboot mode. I can connect it to adb and get it listed in adb devices just fine. I set it to always trust the computer. I try issuing a "adb reboot bootloader" and the Pixel C screen shuts off like I would expect. The screen goes black, then...nothing. The rainbow lights on the back light up as though it's powered on, but nothing ever happens.
Troubleshooting:
So far, I've tried turning off the device completely, then powering it up while holding down the volume- button. This gets me the same black screen with the rainbow lights turned on.
I've tried holding volume- & volume+ while booting, and that gets me into Safe Mode (whatever that is). I've tried volume+ and power, which doesn't seem to do anything at all.
I checked device manager, and the device gets detected when it is in OS, but when I issue it the adb reboot bootloader command, and get the black screen, NOTHING shows up in device manager. No "other device" or "unknown device" or "android device" anything. In fact, listening for Windows audio alerts, I hear the device disconnect when it reboots, then I never hear it reconnect.
At some point after boot cycling it multiple times, it came up saying "The device is having trouble booting, you can click try again or you can try reformatting." It looked like the stock recovery, but not fastboot or anything. Haven't gotten that to show up again. I did go through with the device wipe.
If anybody has ANY ideas for how to get this thing booted into fastboot, please send them my way. It would absolutely make my week
EDIT:
Just tried this and am getting somewhere hopefully...
I did "adb reboot recovery" and it gave me the dead Android screen. Did Power & Volume+ and got the menu opened. Was able to get an adb sideload working and I sideloaded the latest OTA. Here is the logs shown on screen:

All i can get is this screen. It doesn't boot or charge only this. I tried power+volume up, volume down etc. still did not work. Also i tried other charges.
All I can manage to enter is that white backgrounded screen then i tried to enter the recovery and again i get that screen.
I plugged to PC and i hold power, vol up vol down etc. i just hold randomly. And I got windows connected sound. All the alphabet came through as disks.
These are the not empty ones:
After that I hold the power button I got these:
Than it returned back to the image in the first post.
I still can see the htc splash screen after 2 seconds first image in the first post.
And also sometimes i am managing to connect it to PC. QHSUSB_BULK is the device name

Did you try holding power+vol up for a minute or more?

Actually I tried all those stuff. Now the only thing that I can get is boot screen. I can enter the fastboot but i have no idea what to do with. And also when i enter fastboot my Windows 10 can see My Htc name under the device manager.

This is all a good thing, and points to your phone being recoverable.
From what you've posted, its sounds like YES power + vol up works (this function forces a reboot) and power + vol down get you into bootloader. So the phone powers on; the main issue is not booting into Android OS.
To determine the path forward, we'll need more info. Please do fastboot getvar all, and post the output (delete IMEI and serial number before posting).
Dear developers!
After successfully flashing and upgrading a friend's Samsung, I got the courage to do the same with my Lenovo Vibe P1.
I followed this video and everything was perfectly: I unlocked the bootloader, connected using QFIL and flashed the TWRP recovery he provided, until the 8:00 minute in the video the program said "Waiting for reset done..." and my QFIL just stucked on that message, so after waiting 5-7 minutes I disconnected the cable in hope that it will reboot to recovery, got some log errors and since then the phone is hard bricked.
Turning on does not work, recovery/bootloader/charging does not work, essentially the screen is dead, the only thing that works is recognization in QFIL program.
When I try to flash stock rom or that recovery from that video again, it first says a protocol error:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
When I try to Download again, now it gets stuck at the Working folder (last message in the log, see below)
EDIT: Depending on the QFIL version, the version below actually gives the same error as above after few minutes.
In addition, any attempt to connect the phone to Windows using USB results in numerous partitions being shown from the phone internal memory (many of which Windows does not recognize as formatted):

Is there anything that could be done to recover my phone please? Not having the right financial situation to purchase a new one and school starts soon so pretty bad situation for me now.
Kind regards,
kangarko
Update! I deleted all partitions from the phone and was successfully able to flash a couple of ROMs from the Internet (including a stock one). However, after each flash one, I get the "Waiting for reset done..." message and than the phone gets disconnected from my Fusion (virtual Windows 7 in Mac), and when it gets connected again it says Finished but the phone is completely black. No signs of any activity, it does not restart itself nor vibrates, and I end up with the problem in my first post again ;(
Help still needed... noticed I typed "Lenovo" in the thread title instead of Vibe, I corrected that but the PHONE IS STILL BROKEN.
Alright, got it solved somehow.
Flashed "P1a42_S272_160506_ROW_QPST" using QFIL 2.0.0.3 and Lenovo usb drivers v1.1.33 + Qualcomm drivers 1.0.
Newer QFIL versions are disfunctional over my device.
Always make sure to hold Power button for 13 seconds to make sure the device is OFF, then connect to QFIL. After it finishes the flashing process, simply disconnect and hold Volume UP button + Power button for 13 seconds and than again to make it boot.
You can find some useful stuff here (including TWRP):

Hi there.Did you experience USB not recognized?I already removed the battery-reconnect-hold volume + then connect the usb cable but still USB not recognized.
Hello,
I got an issue with my Xiaomi Redmi 7. I was trying to install TWRP with adb, but something got wrong, and now my phone seems dead, bricked.
Nothing happens when I try to turn on, can put on fastboot mode (with power+volume down), nor restart it with power+volume up. The screen are just black, and even the notification led doesn't light up when I connect the charger. My guess is the phone is in EDL mode.
Connecting to my computer it recognizes it as "Qualcomm HS-USB Diagnostics 900E", and I can see it on MiFlash, but when I try to flash any stock rom, it stucks in the very beginning. Here's a screenshot:

I've tried different versions of the stock rom, MiFlash and computers, but got the very same result.
Do you have any idea what can I try to bring it back to life?
Thank you in advance!

Hey mate, I'm not sure if you fixed it or not but I'm pretty sure that if it can boot to fastboot it's not bricked. What I suggest you would do right now is install xiaomi drivers onto your pc first and foremost (this actually fixed all my problems) then try to use adb and fastboot tools to fastboot flash recovery twrp.img. if that works you're safe and then proceed to advanced wipe, then vendors and system wipe then in an SD card or an otg flash USB install the lastest global or Europe ROM for miui 11.
Google release Android 12 Dev Preview and i decide to sideload that on my 3xl device (It not my daily use device so it fine for me)
1) I connect the phone, use adb reboot recovery in ota intrucstion and the screen gone black
2) It not show in adb, not show anything in the screen. I use Power + Vol Down for a while, then it show on adb devices with Window add device sound
Current State: + Black screen
+ Have vibration
+ Receive charging and show on adb, i use some adb command to check and it have 100% battery
Case i think happen:
+ No battery, no boot up : I tried use adb command and it in 100%
+ Screen die, error (Hardware): I dont think that happen because it working fine for me and i not did any damage to it, just reboot it to recovery. I tried a type-c to hdmi and connect it to my monitor but it
not render anything
+ Some firmware problems: I not flash anything yet, just boot it to recovery so i dont think this case happen, i tried some method like hold power, hold power + vol down but not work
It really weird things for me, it is the first time i see a device working normally just gone to black screen by boot to recovery, non respond in screen (squeeze gesture and fingerprint still give vibration), not ringing by call.
Some note may useful: I tried hold power + vol down, then hold vol + while still hold these two button, some kind of strong vibration happen then everything still the same
I really looking forward to people have the same problems and solved it!
Surfaceflinger might have been corrupted, so the only thing you can do now is try to guess the key combination for bootloader, or just use adb to boot into bootloader mode. Then flash the latest factory image. That will hopefully fix it.
My device not have oem unlock option, so seem like enter bootloader to flash image is not possible
But i have some update, i used a tool https://github.com/Genymobile/scrcpy and i show my display
to my computer

I try to touch on screen, use button, ... and everything seem like work. Only the display not display anything, just the black screen. At this point, i think it because of hardware problems - sound like so weird because i just run the device to recovery by adb
Model: LG K10 K430dsE
Spoiler: bootloop error

Bootloader is unlocked / oem unlock / usb debugging ON
This happened after i tried to adb reboot fastboot flash twrp.img (because without flashing twrp ididn't launch)
Now my device is bricked? - maybe it was even wrong twrp version, whatever couldn't find anything official for the exact model and device is old
When the phone starts i get the following message
"Your device is corrupt. It can’t be trusted and may not work properly"
Stuck into a bootloop
1. 'adb devices' does not find the connected phone, neither 'device manager' (did before) - cannot start twrp
2. Pressing UP and connecting USB, it goes into Download mode for ~10 seconds then exit and shows;
"Your device is corrupt. It can’t be trusted and may not work properly" and goes into a bootloop again
2.5 PC recognises the COM/PORT for a split second in LGUP + LG Bridge , then it goes away cause phone loops so i cannot enter upgrade and flash the .kdz
3. LGUP shows 'There is no handset connected. Please, connect a handset(s)'
4. LG Bridge does not see the USB, tried different PC and ports.
5. Removed battery, press UP + connect USB device tries to start and closes in 1s
6. When i try to go into download mode, windows shows
'MT67xx Preloader' Looking for updates/drivers, but fails to find it,
Download mode goes into bootloop again and shows 'Your device is corrupt etc'
Spoiler: flip
99,9% i will hear "your device is hardbricked and there is no fix"
It was probably wrong twrp img, K10 K430XX - flashed it and now the phone is gone prob
edit; pressing UP + connecting USB, will show on LGUP and LG Bridge, the device
'connecting' for a split second, then goes away - phone from download mode for 10s will go to bootloop again
