Which type of brick, and how to recover? - OnePlus 6 Questions & Answers

Hi, several months ago I believe I tried to root my OnePlus 6 and it resulted in some kind of brick.
When i power on the device it shows the OxygenOS loading animation for several minutes and restarts multiple times. Then it boots into some empty android menu (usually a black screen with the power options when i hold the power button)

What kind of brick is this, is there a guide to fix ? Thanks

Got it working back on stock now.
eventually got into fastboot, unfortunately my pc didnt pick up the device. USB issues are a pain. roommates PC booted TWRP on the phone after a few attempts and we got it installed. Sideloaded stock image (overwriting custom recovery) and it booted setup just fine. testing it out now.

[SOLVED] Rooting failed, please help

Hey everyone. I got my S8+ today and I haven't rooted a phone since my S2 and that was like 4 years ago. I was a bit stupid and started to root my new phone and used twrp-3.1.0-1-dream2lte.img and it seemed like a success but now my phone won't go into the TWRP or past the turning on screen. I've been trying now for 5 hours to find a solution but without success. Now anything I try in odin mode turns to FAILED. Does anyone have a solution?

SOLUTION:
Boot into download mode but don't press to continue. Restart but immediately boot back into download mode and continue and flash what you are trying to flash For some reason this worked after 9 hours of trying everything....
Interesting. Tks
This works, it's due to the phone not being recognised the first time in download mode for some reason

"Your device has been unlocked and can't be trusted." after trying to install TWRP
Hello everyone,
I was trying to install TWRP and flash an image to my Honor 6X but at some point it just wouldn't want to reboot anymore and just stayed in the following screen.

Does anyone know what to do now? Just booting into the OS would be enough.
Edit: Just left it charging and it booted, lol
Edit 2: after trying to reboot into bootloader its stuck again :/
Edit 3: It booted again after like half an hour. there doesnt seem to be any logic behind the reason it boots. Sometimes it does sometimes it doesnt.
Power off device by Holding power button
Then boot into bootloader by holding volume down and plug usb
Then Flash elite twrp

I have a Samsung Note 10 (N971N) which was rooted and on Android 10. I flashed TWRP but it didn't work and I don't exactly remember what I did because my phone has been down since the past 36 hours. I've tried everything, downloaded and flashed 3-4 stock firmware for my phone but nothing seems to work. My phone automatically boots to this screen that is shown in the picture. I've tried connecting it on Smart Switch as well as it says on the screen (in Korean) but that doesn't work either. Whichever firmware/recovery I flash using Odin, it gets stuck on Recovery.
I've tried flashing HOME_CSC and CSC both but nothing works. I was trying to save my data but now I just want to get my phone back up again. Googled and found nothing useful, would really appreciate some help!
At the top it says:
VOLTAGE LEVEL (4148)

Pixel 2 Hard Bricked due to being flashed with fastboot stock ROM/firmware (No EDL, No Fastboot, No Charging screen)

Hello, I've been searching for the past 4 hours on this problem and seems like most of people's Pixels were forced into EDL mode.
However, mine was flashing with Android 9 bootloader (walleye-pq3a.190801.002) from my local drive (I assume it was corrputed) when I was downgrading from Android 11 stock rom, it was a successful flash (walleye-rp1a.201005.004.a1)
Before it can flash the radio partition. It got bricked immediately. Hold buttons only twitches the OLED screen up. Nothing pretty much outputs the screen or recognized by computer.
I wonder how because like it was flashed successfully with the bootloader with the walleye-pq3a.190801.002 build while the zip file doesn't have CRC error when it was extracting.
Below was the progress of the flash.

Pixel 4a troubleshooting

Hi I was wondering if anyone would be able to help me troubleshoot my device before I take it to a shop. I was browsing on it today and it froze and black screened (80%+) battery. When trying to plug into the computer and power into fastboot (Power + Vol Down) I get an audible that the computer is registering the device for a moment before it instantly disconnects. I tried booting via ADB but it's unable to connect to the phone as it's instantly dc'ing. Regular fastboot and power cycling did nothing, this has been a past issue but has been resolved by simply plugging in and waiting ~10 minutes which does not seem to be working this time

I've got it to recognize in my device manager yet ADB is not detecting it at all. (Worried the device is not in M2P mode), any suggestions are welcome
Update: Holding the power button for the (100th time at least). Let my phone boot up
