Can't access fastboot and adb no matter what. - Nexus Player Q&A, Help & Troubleshooting

I haven't used NP for the last year and now when I decided to give it a go it's suddenly stuck in bootloop. First it booted as normal, but just out of the blue the screen turned black and bootloop was a fait accompli. Now all I see is the Google logo. I've been trying to access fastboot for days now.
I've switched cables, downloaded drivers manually etc. but nothing seems to work. Could USB3 ports really be the reason it's not connecting? Guess it would be my last resort before attempting a factory reset. The situation seems hopeless.

Probably bricked LG G2 running SlimSaber

So basically this rom is awesome but it had only one problem. When I plugged my phone in the charger while it was turned off, it bootlooped until I restarted with the cable off. It was no big deal and nothing bad ever came out of it.
Yesterday my batter ran out while I was asleep and when I woke up it was already turned off. I, absentmindly, tried to turn it on, LG Logo, off again. Did it one more time, nothing happened, realized it's out of battery. Plugged in charger, try to turn it off/on, usual bootloop happens. Say ok and proceed with what I always did, phone gets past LG Logo, goes into SlimLP boot animation and for the first it has just stayed there. No restarts, just endless loading. Longest i Left it on to load was about 45 minutes. Never got back on.
Apart from that, I think that for some reason my recovery got uninstalled somehow, by itself, a few weeks ago. I only noticed this because before, when I wanted to get into recovery, I pressed the usual buttons and it went straight into TWRP. Now the same buttons take me to the "Factory reset screen". I know that everyone says to just go ahead and press power, but I am afraid, since I am not sure if TWRP is still functioning. This happened to me another time on the same phone, and when I confirmed the factory reset, it factory resetted.
My problem here is that I want to get my music and photos. I'm only able to enter that factory reset screen and download mode. Can I "flash" twrp safely from download mode? Should I use Flash Tool 2014 and Normal flash(which says it keeps the data) a stock g2 rom? Can I mount my phone to the computer in download mode to copy my files? I want the most risk-free approach.
Thanks in advance.

Hi, first If you can enter download mode I think you can flash kdz (Kitkat) file to stock using Flash Tool 2014. But I had this problem once and the keep data flashing didn't work (stucked at 50%), I ended up flashed it with other option (erased all data).
2. You can try the "Factory reset" nice and easy.
I think you can't see files on the device unless you enter Twrp.
It's wise to backup your phone on the computer montly or so, thank you.
I went ahead and nuked my download mode using the SRK tools. Then got access to fastboot, through which I booted to twrp and then I could move my files. All's fine, flashed my ROM again and it's going better than ever.

Help with strange bootloop

So, my G4 Plus got itself bricked out of thin air. I got it last year , unlocked it ages ago, tried some ROMs but decided to go back to stock+ because of pesky camera problems.
Earlier today i was using it normally when it froze and a long vibration started. With no other options I made a hard reboot and it started up again, only it didn't... The boot animation came out all choppy before rebooting itself again. Sometimes it lasted longer, sometimes a bit shorter but it never fully booted up again. Back home I booted into TWRP, flashed cache/dalvik, nothing. It DID get to a full "G" logo, then rebooted itself again. Got a ROM into the SD card, started flashing, froze, reboot again. Tried formatting everything, same thing, froze, reboot.
Just about the only things I can do with it are boot to TWRP and do anything that doesn't involve storage (so pretty much useless) and bootloader.
I also tried just about everything in my power to flash it on ADB/fastboot, but windows itself won't recognize the thing. All sorts of drivers, command lines, windows test mode (for driver certificate shenanigans), nothing worked. I even tried the same on a netbook with win7 since my desktop doesn't have a single USB 2.0 and I heard ADB has trouble with 3.0, nothing again. It doesn't recognize the device at all. They do recognize my girlfriend's G5 by the way, but seem to want nothing to do with my crippled-down-to-bootloader G4+.
I need some help guys, any clues?
Remember:
-Not your everyday bootloop
-Stuck with bootloader and limited usage of TWRP (i can copy files from SD to Internal with no problems)
-Neither Win10 with USB3.0s nor Win7 with USB2.0s recognize the phone at all, at least in this state (every driver out there already installed in every order)

can't recovery mode

Help
Initially I replaced the LCD. After being replaced with a new LCD, the first use is still normal. But after a while, my device turns off. But after being turned on again, just stuck on the mi logo. Then I tried it repeatedly but still stuck on the mi logo. Then I delete all data and do wipe partitions. But always experience unusual things. Loading cleans the data running, but when it's 5% it arrives directly to 99% and my device turns off again. I have tried many times, but always with the same results. And finally I tried to flash with recovery mode. The process went smoothly and looks fine, after the flash finishes, the device is restarted. But after being restart, after all this time, it just stuck on the mi logo. Then finally I removed the battery and I put it back on. But after I turn it back on, it just stuck on the mi logo again. Finally I tried to enter recovery mode, but apparently what appeared was the inscription 'the system has been destroyed'. And finally I flash using fastboot mode, but the device is still locked. And I have used edl mode too, but always asked for an account that has been authorized. Is there any other way? Please help, because I really need to use this device.
Thank you for those who helped

Screen stopped functioning while system still working fine

My phone screen stopped functioning, as in it stays as a black screen no matter what, during boot up, recovery, and Fastboot screen. The phone system itself is still functioning, If I boot into the system I get notifications from my apps which causes the notification LED to go off and I feel notification vibrations.
The most confusing part about this is it happened randomly, I checked my phone in the morning and it was fine, I shut it down and left it for an hour and came back and that's when I started having this issue.
I have tried rebooting the phone many times, and also to recovery and Fastboot and no luck, the screen stays black. I can fortunately access my files through my computer when I connect it through usb and its in the recovery screen. Also, Fastboot recognizes my device through my pc when its in Fastboot mode.
I have checked it around and it doesn't seem anyone has had this issue except maybe this guy:
https://forum.xda-developers.com/mi-9t/help/black-screen-9t-t3999649
But he doesn't seem to have found a solution.
As for my ROM, I was running Pixel Experience Buttery Smooth and I have also used the screen overclock mod:
https://forum.xda-developers.com/mi-9t/themes/screen-overclock-mode-t4079693
However It never ended up working for me so I stopped using it months ago.
If anyone has any suggestions for what I can do, I am extremely desperate as sending this phone for repairs is going to be really hard to do, I am really hoping this is an issue I can solve without doing that.
Thank you for any help
So I decided to try accessing my phone through my Pc by using a software like Vylor to mirror my screen to my PC, the problem is I can't get my device to be recoginzed by ADB. It is recognized by fastboot when in fastboot mode and when it is in recovery I can access all my files through the file explorer. However, when I boot my phone normally it adb does not list it under adb devices when it is connected through USB.
Does anyone know what could be the issue? I am sure I had usb debugging on before by screen stopped working.

Totally borked phone, need advice

I used to have a Pixel 5 phone, which unfortunately was run by a truck and now I am stuck with an old Samsung Galaxy S7 Edge phone. I have decided yesterday to install Pixel Experience on it and it all went fine. I have unlocked the OEM, enabled USB debugging, installed the latest version of TWRP with heimdall, and sideloaded the Android 11 Pixel Experience Plus ROM.
I had done a full wipe of the phone before doing it, including the system, etc. I have then recovered from the backup from my Pixel, and it installed all apps. Then I saw that there is a new version of the Pixel Experience, installed it, and plugged it into the charger and I woke up at the Google logo. I disconnected it from the charger and the Google logo was still there, it took me a couple of minutes to switch it off while holding continuously the power button.
I tried to go into recovery or download mode without any success. Then I have connected it to the charger again and I saw the battery indication with lightning inside, but normally it also shows you the battery percentages but this time, it didn't. I have then tried to connect to my PC, thank God this time, it booted straight into recovery. I have tried to sideload again the ROM, and this time, it worked till the end, but then I was unable to slide the slider to unlock it and restart the phone. Then switched it off and tried once again to sideload it, this time the phone died at half of the sideload. I am completely desperate now. Am I doing something wrong?
