[Help]Oneplus 6T stuck on fastboot screen, can't turn off - Android Q&A, Help & Troubleshooting

So I just now tried to root my Oneplus 6T. I followed this guide: https://www.xda-developers.com/oneplus-6t-unlock-bootloader-root/
The steps I went through were:
1. Enabled unlocked bootloader, enabled debugging USB mode and set USB mode to file transfer
2. Ran "adb reboot bootloader"
3. Ran "fastboot oem unlock"
The phone reset and rebooted, and I redid steps 1 and 2.
4. Ran "fastboot boot twrp-3.2.3-x_blu_spark_v9.91_op6.img" and got the message:
Sending 'boot.img' (28664 KB) OKAY [ 0.627s]
Booting OKAY [ 0.069s]
Finished. Total time: 0.877s
After this it tried rebooting and it is currently stuck on the fastboot mode boot screen. I've tried the following:
1. Turning it off by holding the power button >15s - Didn't do anything
2. Turning it off by holding the power button and volume down button >15s - Didn't do anything
3. Running "fastboot reboot" and got the message "< waiting for any device >" and didn't get any further
My current thought is to let it run out of charge and try rebooting it into the bootloader. However, this will probably take a very long time, since it was quite full when I started. Any ideas for what might fix this?

If you can enter in fastboot mode try with Tool All In One application :good:
You can do eveything with it

I solved it by letting the phone completely discharge and then booting it with twrp-3.3.1-17 instead.

But I just realized, it's for ulefone Armor 2, while I try to root a Armor 2S..
I followed instructions, but I've got a problem on the point 2.

After few test, who doesn't work at all, I've decide to reboot my phone.
Now, It's stuck on the main screen with this text :
Code:
Orange State
Your device has been unlocked and can't be trusted
Your device will boot in 5 seconds.
And after 5 seconds, the screen go black for one second and return to the message.
And I can't go to recovery mode anymore. Volume+ and Power button don't do anythong but show this "Orange state" screen.
Please tell me there is a solution to unbrick this phone..
Thanks in advance
Try to relock again bootloader with command : fastboot oem lock maybe it can fix that issue but do at your own risk !!!
Thank you for your answer, but the phone is not recognized by the computer at this point.
I can not send command from the PC (adb or fastboot)
Try some key combination keys like :
hold Vol + and plug usb
hold Vol - and plug usb
hold Vol + ; Vol - and plug usb
If that doesn't work , let your battery to be completely empty 0% and repeat process . Good luck

fastboot boot twrp.img FAILED (remote: unknown command)

Hey guys,
I have an European LG G5 H850 with an unlocked bootloader. It is my first time rooting, and after unlocking the bootloader, I wanted to boot TWRP once, but I didn't want to install it, but instead keep the stock recovery untouched. So I booted into the bootloader, entered "fastboot boot twrp.img" and I got this message:
downloading 'boot.img'...
OKAY [ 0.462s]
booting...
FAILED (remote: unknown command)
finished. total time: 0.482s
I have absolutely no idea what I'm doing wrong. I made sure twrp.img is referring to the correct file, and I tried both the Android SDK platform tools and the 15 seconds ADB installer, but none of them worked. When I try flashing the recovery with "fastboot flash recovery twrp.img", it seems to work because this appears:
target reported max download size of 536870912 bytes
sending 'recovery' (20900 KB)...
OKAY [ 0.471s]
writing 'recovery'...
OKAY [ 0.198s]
finished. total time: 0.670s
But when I try to boot into the bootloader again, it just gives me the option to do a factory reset, nothing else. So I assume that something went wrong. I have absolutely no idea what it could be, so please help me. I also asked on reddit, but didn't get any answers so far. Any help would be greatly appreciated!
Thanks in advance!

The "fastboot boot twrp.img" command didn't work for me either, but the keystroke to do a "factory reset" -- which is really a keystroke to enter recovery -- did work. Specifically, I
powered down the LG G5 completely (nothing attached to the USB-C port, or battery pull)
with the power off (preferably via battery pulled), held down the Volume Down and Power/Fingerprint buttons
As soon as the LG logo appeared, released and re-pressed the Power/Fingerprint button, all the while continuing to hold down Volume Down
Held down both while the LG logo showed, releasing them after the white screen appeared asking whether you want to do a full erase. Answer yes (Press and release Volume Down until the Yes is grey, then press Power/Fingerprint button)
It prompts you once again. Answer yes again the same way.
At this point after a few seconds, TWRP starts. It hasn't actually done an erase.
This is important: after fastboot flash recovery twrp.img, you need to pull the battery to power down, and then follow the instructions above to enter TWRP. Do not boot into system with the stock ROM after fastboot. It will replace TWRP with the stock recovery at boot time, and in that scenario, the full erase mentioned above actually does erase data and internal storage.
TWRP will on first start change the system image (once you "allow modification") so that the stock ROM stops replacing it at boot time.
If you did boot up the stock ROM after fastboot, you will need to re-enter fastboot and flash TWRP again (power down with USB-C port clear, hold down Volume Up, insert USB-C cable, fastboot flash recovery twrp.img). Then pull the battery with fastboot still running, then boot into TWRP as above.
Unfortunately most writeups aren't crystal clear about the correct sequence of steps. Most cover some steps and gloss over others.
You aren't doing anything wrong.
LG did not put the typical Fastboot commands into the bootloader.
Fastboot flash does not work either.
You need to follow the other methods available on xda to get TWRP on your device.
Edit: woops. That's only with H830. Follow the instructions in the H850 TWRP thread.

Question Unlocking OEM without access to the OS or the TWRP

I have a Moto G Play 2021 (XT2093-4) (another one), that I made a mistake to relock the bootloader after I had it unlocked. I don't have access to the OS on the phone anymore. Previously I had the treble floss installed on it. I don't have TWRP installed. The only thing I have access to is fastboot. I realise I might have completely bricked this phone but I thought I ask here to see if there is any way to unlock the OEM again just using the fastboot.
the fastboot screen on the phone has a menu option to go into recovery mode. stock recovery might be able to restore your phone to working condition.
volume-down + power buttons > fastboot mode > volume button to 'recovery' option > power button to execute. if your recovery screen is broken with the 'no command' message, hold down the power button and quickly press and release the volume-up button. that should get you to the working recovery screen where you can try to factory reset your phone.

Thanks, but I think my phone is completely messed up now. If you can believe it, I can't even get to recovery mode. I can get to fastboot and then find the recovery mode and click to go to it but then it just starts the fastboot again. I'm basically stuck in fastboot forever. It's just weird cause there's nothing wrong with the hardware. Thanks again.
if you have nothing working on your phone but fastboot mode, that might still be enough to rescue your phone. boot it to the fastboot screen, connect it to a pc that has the fastboot program installed, open a terminal window on the pc wherever fastboot is, and type 'fastboot devices'. if your phone answers with its serial number, you'rr probably able to flash a whole stock rom to it piece by piece. get a stock rom from somewhere like lenovo, using their lmsa program, or just download the right one from lolinet or somewhere. unzip it. then, for instance, to flash the boot.img to your phone you would type 'fastboot flash boot boot.img'. that would replace your possibly broken boot partition with a known good one. then 'fastboot reboot' to see if that helped. there are tutorials on the net for flashing the rest of the rom. be sure to read one, because all of the flash commands aren't that straightforward.

Sorry for the really late reply. I tried what you said, but it fails right at the (fastboot flash partition gpt.bin) command and the output I get is:
Sending 'partition' (37 KB) OKAY [ 0.002s]
Writing 'partition' (bootloader) Validating 'gpt.default.xml'
(bootloader) flash permission denied
(bootloader) Cancelling 'gpt.default.xml'
FAILED (remote: '')
fastboot: error: Command failed
It keeps saying flash permission denied. I have another exact same phone with an unlocked bootloader and I did the same on that one and I was able to flash a stock ROM to it. I've tried every RETCA and RETUS on this site: https://mirrors.lolinet.com/firmware/motorola/guamna/official/ but it fails with the same error. I'm going to try all the rest later but it's a lot to download for now.
Thanks again for the help!

Question Honor 50 Lite stuck on looping logo screen

Hello I am trying to boot my phone to recovery mode to do a factory reset since it keeps restarting and it does not passes the Logo screen, it is stuck on a looping state. I tried to access the recovery mode usign the volume buttons but is not working, it keeps restarting. I did not enable debugging usb since I never knew I was going to need it. Any help will be greatly appreciated.
lol easy.
if your has problem, can you boot your phone into fastboot, don't request usb debbuging.
install this file and unzip it on your pc. https://dl.google.com/android/repository/platform-tools-latest-windows.zip
now open this folder and open cmd window inside it.
and run this command "fastboot continue" for continue normal booting.
if you need to reset your phone, can you use this command "fastboot -w"
Thanks,
I've tried that but is says command not allow.
C:\adb\platform-tools>fastboot continue
Resuming boot FAILED (remote: 'Command not allowed')
fastboot: error: Command failed
Then I tried fastboot reboot to fastboot and it gave me this
C:\Users\Aiven>fastboot reboot fastboot
Rebooting into fastboot OKAY [ 0.001s]
< waiting for any device >
fastboot: error: Failed to boot into userspace fastboot; one or more components might be unbootable.
it goes back to the looping stage again.

Help Please... unable to boot into TWRP (or Orangefox)

First time poster.... please go gentle on me. Not entirely new to custom roms and TWRP, but really stuck here. I am trying to install a CrDroid ROM. Phone is not networked locked and brand new. What I managed to do so far:
1. Reset the phone
2. reboot into Recovery (Mi Recovery)
3. Wipe data
4. Unlocked the phone (using offical Mi Unlock)
I then proceeded to boot into Fastboot and flashed the TWRP (twrp-3.7.0_12-0-onclite), renamed to recovery. But after flashing and rebooting I can only get into Fastboot, or boot it normally. Holding down the Volume+Up and Power button doesn't get me anywhere but Fastboot. (Same for Volume-Down and Power Up). I tried both un-pluggin the phone from the PC immediately after flashing is finished, and using Fastboot Reboot command, but all to no avail. Its Fastboot or normal boot only.
I also tried whats suggested here upto the vbmeta image, but didn't make a difference. When sending the 'fastboot boot recovery.img' command, I get the following error:
C:\adb>fastboot boot recovery.img
downloading 'boot.img'...
OKAY [ 0.939s]
booting...
FAILED (remote: unknown reason)
finished. total time: 1.502s
Trying this guide for a 'custom' boot image from this page also didnt help
Really hoping there is a way to get this resolved. But totally stuck here. Have access to both Mac OS and Windows 10. If anyone can point me in the right direction it would be wonderful!
Ok, small update - in hope to help others...
I went ahead and used 'XiaoMiTool V2'to see if it might help to load a different ROM. When starting the app, I choose the 'Bricked' device option, even it wasnt bricked. I choose the Global ROM 12. (The phone showed up as unknown and I didnt sign in with the Mi Account).
After the new ROM was on it, phone started normally and went through the setup. Had to re-enable Developer Options, USB Debugging, but even so it still didnt work - installing the TWRP just kept bringing me back to Fastboot.
However, the TWRP from this page did work: https://twrp.me/xiaomi/xiaomi-mi439.html
I also took no chances and held the Volume up button pressed and with the Command window open and 'fastboot reboot'typed out, hit the Enter key at the same time as pressing the Power button on the phone.
Worked for me!
