OnePlus 6T stuck at bootloader warning screen - OnePlus 6T Questions & Answers

I was trying to install TWRP on my 6T. The bootloader was already unlocked.
After flashing TWRP, my phone is now stuck at the bootloader warning screen (as it's unlocked).
I can't enter into fastboot. It won't even shut down.
I have tried all key combinations and only vol up + power key works but all it does is restart the device and it gets stuck again.
My pc isn't recognizing the device either.
What should I do?

try vol up + down + power to enter into fastboot

P9 lite l31 Boot loop that I can't find any information about anywhere! Unique, yay.

I tried to update my wife's P9 lite to Nougat manually and initially succeeded in some way. The version I installed via the dload install method turned out to be some sort of Bluetooth disabled demo firmware (I can't remember the name of it).
I then tried to downgrade back to MM 6.0/EMUI 4.1 and now have a bricked phone. I can't actually turn it off!
Hard reset options do nothing.
Here is the current situation:
The phone is always on - the Huawei logo is displayed with 'powered by Google' at the foot of the screen.
Holding down the power button returns the phone to the same screen after a vibration and a brief moment of blackness.
Holding all three buttons results in a double vibration then back to the same screen.
Power and down vol leads to black screen, vibrate, back to logo screen.
Power and vol up is the same as vol down result.
I'm out of ideas. Nothing online mirrors these faults. I'm ashamed to admit defeat but it is as dead as I've seen any handset. I can't believe it won't even power down. I'm in the doghouse here. Wife is not happy!
Download any update eg b161, download trwp and connect your phone to PC then press power + vol down. U should land to fastboot then open adb/fastboot and type fastboot oem unlock "unlock code" then enter if u get unlocked then flash trwp by fastboot flash recovery trwp.img after that go to trwp and flash the update.zip u downloaded. Then reboot

Thank you but it goes straight back to the logo screen when I try this.

Bricked YotaPhone 2, Bootloader locked, No Recovery

Hi pros,
- Yotaphone 2, was on 6.0.1 when bought (pre owned).
- When trying to do Settings -> Factory reset, it would flash the 'powered by android' logo' and then show the animation for some time, but wouldn't reset the phone completely (the older google account would still remain)
- I tried to get into recovery mode by (Power + Vol Up) combination. It would show the 'powered by android' logo for a second but not show the 'recovery' screen.
- Then I went into the fastboot mode by (Power + Vol Dn) combination. Tried Fastboot oem unlock. Again the 'powered by android' logo would show up for a second but no confirmation screen to unlock bootloader.
- I could still just long press the power button and the phone would boot up normally.
- (here comes the mistake) I flashed twrp_xxxx_backtobusiness.img using fastboot flash recovery twrp_xxxx_backtobusiness.img
- Now I am in a state where the bootloader is locked, no recovery and the phone does not boot. I can only get to fastboot mode.
It would be great if someone could help me recover my phone from this state. Thanks.

stuck in BootLoop

Hello i installed on my Rooted and Bootloader Unlocked Oneplus 6t the pixlify module
Then i clicked restart and now i can only see the Dark Google Boot animation
I Already Tried :
Turning off (restart) while pressing power and volume up to go intop Recovery (TWRP)
Its just not working i cant get into twrp
What happens Exactly after i pressed : power and volume up
Phone restarts
I see the Bootloader Warning
And then again the Boot Animation
Volume up + Power combination boots into bootloader not recovery, recovery combination is Volume down + Power.
Anyway you can't even boot to bootloader? Or it restarts after booting to bootloader?

You need to delete this module, you shouldn't install any magisk module without reading what they do or how they work.
It's perfectly stated in the repo that pixelfy isn't for OOS (Oxygen OS).
You need to boot into TWRP recovery, If your device is detected on your PC try adb reboot recovery
Or if it's detected in fastboot/bootloader then use fastboot boot twrp.img (Replace twrp.img with your image location and name)
If it's not detected try fastboot continue (You may have to spam this command for a couple of times)
Note: To run these commands you may want to install your device specific driver and adb tools. You can get the driver from here.
If you successfully booted into TWRP then flash pixelify zip again to completely uninstall it.

stuck on boot, can't go to recovery/bootloader (volume down button broken)

I flashed PixelExperience plus without the patch, and now its stuck on booting. and since my volume down button doesn't work, i can't boot to bootloader. Is there a way i can boot to recovery without the button or do i have to get it fixed
