Stuck on "Unlocked Bootloader" screen after flashing SuperSU

After flashing SuperSU, my phone is stuck on this "Unlocked Bootloader" warning, but I can't even turn it off to enter fastboot mode...is there any way to fix this or my phone is hard bricked?
( I created a TWRP backup before flashing SuperSU )
( I'm using Android 6.0 )
It happened to me too, but hold Volume Down & Power Buttom for 10 secs, will shut down and restart in fastboot mode.

EDIT:
I restored the backup and used this tutorial. Fixed now.

i would while booting the device keep pressing the power button to force shutdown the device. immediately after turning off, press and hold both power button and vol - keys for 10sec or more and release. this will get you into the bootloader screen. on that keep pressing vol - to select 'recovery' and press vol + to go into the recovery. good luck

that leaves you only with one option. get into the bootloader screen, and flash the latest stock ROM using fastboot commands. then try flashing custom recovery, custom ROM from the beginning. i would skip flashing bootloader though.

still stuck at device is starting screen
found this one is working for me https://www.******.com/install-twrp-recovery-root-honor-6x/
you must have flashed incorrect recovery.
remove USB and try to boot to system, it should boot. but if you try to boot to recovery, you can as you may have flashed incorrect recovery.

Device stuck at bootloader unlocked screen

Today I had a strange issue with my Oneplus 7 pro GM1913 running OOS 9.5.5, device unlocked, twrp and rooted. My device ran out of charge and was turned off. When I plugged into the charger, it boots up and for a few second the oneplus logo and charge the device for some time page came in and then the bootloader unlocked screen came in. I haven't charged the device offline after the battery ran out, it was my first time and i thought it was supposed to be like that. But after some time also it was on the same page. Then i plugged out the device and it was stuck on that page. I tired hard reboot, tried to connect to computer. Nothing was successful. Computer showed unknown device and failed to successfully connect. Not recognised as adb device shown nor fastboot device. Then atleast I tried entering into fastboot mode by pressing power button + volume up. At that time it rebooted into system and then everything was okay. But then i noticed i also lost the twrp recovery. Then i had to flash twrp through magisk manager.
Anyone has any idea what happened? Thanks in advance
You have to flash magisk again after flashing TWRP.

Stuck at the bootlogo
Hey guys, i hope i get some help from here.. tried to root my one plus 7 pro international version installed twrp everything worked fine... and after that i tried to reboot in system mode.. now im stuck at the bootlogo with the red middle dot and the 2 white ones. i cant even turn it of now.. no command are working... can anybody help me to fix this pls?
Thanks!!!
I had exactly the same problem. System was running fine with just Magisk installed (I boot TWRP with fastboot on a computer).
Then I ran completely out of charge, and the OP7Pro wouldn't boot anymore: at power on, it shows briefly the OnePlus logo, then displays the boot loader unlocked warning for a very long time (a few minutes), then goes to the bootloader menu.
I can boot TWRP and unlock the data partition. I will try flashing the stock boot and see what happens (and report).
Edit: I had to reflash stock boot and system to have the device boot again.
hi guys,please need help;I have just unlock bootloader on my one plus 7 pro and i was fastboot it with twrp img but i didn't install the twrp recovery one my phone so now the phone blocked on de bootloader unlock screen, I tried to switched of but always back on the same screen, please need help how to do ,thanks

I figured it out. basically when i get to the above attached image I was required to hold volume up+down+power key until the fastmode doesn't comes up. It will take 20-25 seconds. So you will be required to hold it for that long.

Stuck at TWRP Loop!

My phone got stuck at TWRP Loop!!
So, there is what i did...
I flashed Samsung a7 firmware ANDROID 10 [download from firja] and it worked. I needed to root my phone and tried Magisk new app.
But, with new Firmware I did not had TWRP installed, so I flashed TWRP with oden as instructed in this POST [BTW, I followed first method , not the *****OREO ROOT INSTRUCTIONS:***** ].
** TWRP version is 3.2.3-1_ashyx **
After that my phone got stuck at TWRP Loop.
Phone will not boot to normal , only BOOTLOOP to TWRP. Most of the time TWRP doesn't load fully and TWRP screen seams Black Line [in horizontal axix, MY phone display fine, it seems come from The TWRP!! ].
So, I am kinda STUCK at this TWRP Loop and TWRP load at it LOGO nothing more.
I tried every possible KEY combination to get to the fastboot mode/download mode but failed.
One or TWO time I was able[or it did it self!] to boot into TWRP (TWRP loaded but , with BLACK line) , i tried to enter download mode but failed.
So, what can i do?
-Thanks
I got the same problem, i did this: Power + volume down next when it restarted fast pressed v+ and v- and plug in the cable before it showed samsung logo

Nothing to worry and don't panic,
I've been facing problem like this.
To enter bootloader / download mode. With USB Cable plugged You must press and hold Power + Vol Down button then count it for 7-8 seconds, after that immediately release Power button, and press Vol Up + Down. Repeat this step if fail. U will see Download mode.
Regards.

You hold volume down + power button for 7 seconds and phone will be power off.
Then you press both volume buttons (vol up + vol down) and plug in cable what is connected to computer, this pusch you to download mode of phone.

Hi, Bennie from Holland here, with the same problem: tried to flash Twrp to the Samsung A750FN and now stuck in not working Twrp logo, flashing for 2 seconds and further a black screen< The fastboot using Odin can be used via the method described by szimin22, bur the adb fastboot gives no response. Does someone know the correct trwp version for this mobile or a firmware file that can be flashed by Odin?
A Week Later ...
i have installed on the a7 the firmware dated okt 2020 and i can install without any prob trwrp or PBRP! but the machine goes into bootloop again. The only thing which seems to be resolved is a normal functional recovery. Now the return to the phone itself and we are home! any suggestions, pls give us a chance to not smash the a7 through the kitchenwindow
