[Bricked?] Stuck on Unlocked bootloader screen - OnePlus 8T Questions & Answers

Uninstalled magisk to update OTA to 6.8 (because it wouldnt work) then it just reboots and now its stuck here on the "blah blah your bootloader is unlocked"
OS: 11.0.6.7.kb05aa
wtf can i do, pc doesn't detect it?

Try the below hardware key combination to get into fastboot and flash your stock boot.img (from the correct rom) and see if that fixes it.
If not you can try to flash the latest rom through fastboot.
If that is not working you can always use the MSM/Unbrick tools (see posts in Guide forum) to restore completly to stock (Warning this will wipe your phone !)
To enter Fastboot and Recovery Modes using the physical button combination, you will first need to power off your OnePlus 8T completely. To do this, simply press and hold the Power button to bring up the Power menu and select ‘Power Off’.
Once you have done that:
Press and hold the ‘Volume Up’, ‘Volume Down’, and ‘Power’ keys together to enter Fastboot Mode
Press and hold the ‘Volume Down’ and ‘Power’ keys together to enter Recovery Mode

Have you tried to fastboot a recovery image?
Code:
fastboot boot recovery.img
Where recovery.img is the full path to your correct recovery image on your computer
ie:
Code:
fastboot boot C:\recovery-RA-sapphire-1.5.2.img
i tried doing that but it said
FAILED <data transfer rate failure <too many links>>
**nvm, it worked now**
hm i'm still relatively new to Android, but don't you enter recovery mode through home + power and not menu + power?
wow, I could of sworn I used to be pressing menu + power..Guess I haven't flashed a new rom in a while.
I thought it was Back + Power!?
back + power (and volume down + power) gets you to a boot screen/status screen where you can check motherboard and radio.
home + power is how I've always gotten to the recovery screen

[Q] Key combination to enter bootloader and recovery

Hi all!
Ultra-NOOB question here! I just acquired my One S, rooted it with the all-in-one toolkit and installed a recovery.
Now, which keys do I have to press to enter the recovery from the shutted down phone? And when? Does fastboot need to be turned off?
Til now I had to connect to my pc and adb reboot recovery...
Thanks!

disable fastboot
turn your mobile off
press powerbutton and volume down button and keep it pressed till the bootloader turns on.
navigate with the volume buttons to "recovery" and press the powerbutton here you go

I think I just bricked my phone, Please help

Don't know what I did in TWRP recoverty, now I can't boot into to fastboot or recovery. Black screen with `MI` logo stuck there.
I did tried connecting with PC, adb showing
Code:
no device found
.
What can I do?
Try to enter twrp by pressing Volume up + Power button or fastboot mode - Volume down + Power button. Or let the phone discharge completely and then try the above key combinations.

CANNOT enter recovery mode proper

The issue: When booting I get the "bad key" boot text which hangs for about 10 seconds before going to splash.
When doing power button + volume up, the bad key hangs for so long that holding down power button just SHUTS THE PHONE OFF.
I can do power button + volume down to enter bootloader, and then enter recovery mode from there, but when I do that I get NO COMMAND
Ive also tried with adb
adb reboot recovery
same thing NO COMMAND
Everything that I google about NO COMMAND comes back with "oh just do power button + volume up duh" and each time I read that as a solution it makes me a little bit more angry.

Ive been following this guide to root my moto e6 and everything has been fine so far, but im stuck trying to install magisk. Magisk manager has already been installed, and I believe I have installed magisk. But I cannot boot into proper recovery to use it.
About to give up, hopefully someone can help
installed a bootlogo following this guide
https://forum.xda-developers.com/moto-e5/how-to/boot-logo-moto-e5-stock-bad-key-removed-t3869259
to see if that would help. No change. Cant boot into recovery mode proper.

bad key and/or N/A is just the phone saying it has an unlocked bootloader.
NO COMMAND when entering Recovery, yes, google is right. When you see NO COMMAND, press and HOLD the power button and TAP the volume up key. You should see at the top, Android Recovery and a bunch of options below. If you don't see this, your recovery partition was probably modified/corrupt. Flash the original recovery.img from a stock rom. I don't think there's a working E6 TWRP recovery image yet.
If you still haven't figured this out I have a possible fix. I found that upon first installing the magisk_patched.img from the guide you linked, everything booted up fine and magisk and root were working. I however made the mistake of booting normally...somehow this affects the magisk boot function in the recovery and gives the no command screen. I just fastboot flash recovery magisk_patched.img again and booted straight into recovery and that fixed it again. Just make sure once you have root again to use a program that allows you to boot back into recovery again directly.

When I get to the Android Recovery which option do I choose?
I tried "Reboot system now" and Magisk was still not installed

problem mtk6592

hello i m to unlock oem from adb and reboot tablet but it won't start only restart and go to boot mode volum down not working to choose fastboot
If english isn't your main language then use google translate and I'll try my best to understand.
Anyway, does adb recognize your device? Does adb devices returns devices attached and a serial number?
If so then try adb reboot bootloader
Or try manually booting with volume buttons, usually it's (Volume Up + Power) combination, on some devices it's (Volume Up + Volume Down + Power) combination.
You have to enable USB debugging and oem unlock in settings for any of this to work.
After successful booting to fastboot. Use fastboot oem unlock for older devices or fastboot flashing unlock for newer devices.
Then use fastboot reboot after successful unlocking. Note: Most devices use prompt to confirm bootloader unlocking which in turn requires the user to select "yes" with volume buttons.
If your device doesn't boot to bootloader and you have oem unlock and usb debugging on and tried all of the above. Then most likely your device bootloader cannot be unlocked, which explains why you can't find your device in XDA forums.
I did all of the above, but after unlocking oem, this is what the picture became
volumn down not working
I'm not following here, what exactly happened? Did you unlock the bootloader?
yes I unlocked the bootloader but after fastboot reboot it does not turn on it reboots only as shown in the video
Try booting into fastboot again and using flashing unlock_critical
I can not enter the fastboot mod because it does not work for me volumn down
Is your device detected on your PC? Try adb reboot bootloader
after unlocking oem, the tablet does not turn on and does not see the pc
Try connecting the device to your PC while pressing volume button to boot to bootloader. If it still doesn't boot then you can only fix the volume button.
Can you tell me what's your device model?
my model is x101 china model tablet .
boot only working volumn up
I can not choose boot mode
I never saw a bootloop after unlocking bootloader before. Maybe you modified your device in anyway before doing this? Like one click root apps or anything whatsoever?
If you can get volume down to work then you should be fine. Also try power button too pressing it should have the same effect as volume down.
I haven't modified anything. only the power button does not work only the volume up and the volume down is not pressed Please help me how to recovery system

Is your device battery removable? If so, remove it and wait 5 minuets and connect your device to your PC while pressing volume button to boot into bootloader.
If not then completely discharge your phone and wait for 24 hours. and then try connecting it to your PC while pressing volume button to boot into bootloader.

I discharged it but still nothing fixed
Hence the reason not buy cheap Chinese products. You can only take it to a service center to fix the volume down button.
