HELP! Stuck in fastboot!! (bricked?) - Redmi K20 / Xiaomi Mi 9T Questions & Answers

Dear everyone,
I am stuck in fastboot. I installed the greek TWRP, and cleaned my data by typing ''yes''.
I connected my phone to my PC to put a ROM zip on it, but it only glitched out (it showed multiple storages in Windows)
I restarted my phone, and it won't boot in recovery. When I try to boot to recovery via adb, it just shows
PS C:\adb> fastboot boot recovery.img
Downloading 'boot.img' OKAY [ 0.616s]
booting FAILED (remote: 'Failed to load/authenticate boot image: Load Error')
I am really scared now that my phone is hard bricked. Not sure why though.
Flashing a fastboot ROM wont work either, it just says flash done instantly.
I have done this so many times on my other Xiaomi phones I had without any problems.
And also, is it possible to turn the phone off for now? Because I dont want to have the fastboot screen burned in.
Regards

Did you try flashing the fixed russian twrp? When I flashed the greek twrp on my phone and rebooted through adb it didn't reboot so I rebooted manually and it rebooted into stock recovery. I rebooted into fastbood and flashed the fixed twrp and it worked. If you can get into fastbood you have a chance of reflashing twrp or flashing stock rom so I don't think its bricked yet

Can you flash a recovery using? :
Code:
fastboot flash recovery name-of-recovery.img
If you can, then download a rom and flash it through the recovery that you installed.

[HELP] Recovery Bricked and can't reflash

Hello,
I've decided to install the Beta version of Oxygenos 3.0. Since my phone came from the OnePlus support, I've unlocked the oem, installed TWRP and flashed the Oxygen zip.
However, a day later I've spotted important touchscreen issues (I can't use the touchscreen sometimes).
To see if it is a software problem, I've decided to go to the recovery to reflash a backup. When I try to go to recovery mode, nothing Happen! (Just the oneplus logo ).
So, i've decided to reinstall TWRP by flashing it with fastboot.
"fastboot flash recovery recovery.img" -> OK
"fastboot boot recovery.img"
downloading 'boot.img' ...
OKAY [0.702s]
booting...
FAILED (remote: dtb not found)
Click to expand...
Click to collapse
I've tried to install the stock recovery but I've the same error.
PLEEEASE HELP. I've waited a week to receive my phone because it had a problem but it's broke again :crying:
Note: I can go in Android normally (but with the touchscreen problem)
http://forum.xda-developers.com/oneplus-2/general/firstaid-zip-revert-h2os-mm-beta-to-lp-t3306967 try this.
This happened to me too except I would not boot into the OS or recovery. I ended up going into fast boot and formatting the System, recovery and data partitions. Here is what I typed.
fastboot format system
fastboot format recovery
fastboot format data
I am not sure if you have to format the data but I did.
After that I flashed TWRP
fastboot flash recovery recovery.img
Then I booted into recovery and was able to restore.

I've tested your manipulation and it worked well too.
For those having the same problem OR want to install Oxygen OS the CLEAN WAY, read this post before: https://forums.oneplus.net/threads/installation-instructions-faqs-oxygenos-3-0-0.439108/
It is very important to read the faq before flashing and doing **** like me.

OPT bootloop, no recovery, cant boot into twrp.

So i just saw the new Oxygen OS 3.1.0 is out in OTA form. Me being rooted i tried flashing it through twrp, which i had installed before. (i should also note that i had Xposed installed too, on Oxygen OS 3.0.2) now i think i might have gotten my zip file wrong and installed a previous version. The boot animation is the square, triangle and circle one. It just goes through my apps and tries to update them for eternity. When i try putting the device into recovery (power+vol down) it just freezes on the oneplus logo. I later discovered that i can use fastboot when in that mode. I tired flashing twrp but i couldnt boot into it. fastboot boot recovery.img didnt work either, giving me this:
downloading 'boot.img'...
OKAY [ 0.746s]
booting...
FAILED (remote: dtb not found)
finished. total time: 1.011s
Now i have no idea what to do. I'm sure I've made SOME kind of mistake along the way, but i cant find a way to fix this. I have a nandriod backup of just before flashing if that might help.
fastboot reboot-bootloader puts me in fastboot mode but it doesnt change anything.
also, ADB naturally wont detect the phone whatsoever.
Ill be very glad for any help! Thanks!
Are the drivers accurate? Does your PC recognize your device as it should in Device Manager? That's usually what I check first when I have fastboot errors. I think the only way to fix this is through fastboot... so I would focus on trying to get that to work first.

**** man. I'm in the same boat as of a few hours ago. I was having a ProxyController wakelock and the few Google results I saw told me I should reflash the modem. I accidentally flashed the old modem (OOS2, I believe). I can't boot into my rom OR TWRP. BUT fastboot does work. I also get the "remote: dtb not found" error when trying to boot from the recovery image.
As long as we have fastboot, we can always go back to OOS 3 using the various unbrick methods. I'm trying to avoid having to go through that whole mess of re-rooting/unlock the bootloader etc etc. I'll post on here if I'm successful.
Update: I NEED a functional phone so I just went and erased everything. Sorry I couldn't be of much help to you man. What I did:
I went here and downloaded the fastboot version of OOS3 and converted the bat scripts into bash scripts (I only have Linux computers near me right now...; the commands in that bat script are exactly the same as they would be in bash, I just had to rename the ".bat" to ".sh" and make it executable). I'm back in OOS 3 now, unfortunately. There IS a way mentioned on the page below that talks about how you can prevent userdata from being formatted, but I didn't really care too much. Hope that helps.

Phone stuck on Essential Logo (Powered by Android) screen while trying Oreo B2 OTA

I have tried everything to get this phone to boot up. I was downloading the Oreo B2 via OTA, not sideloading. While the update was installing, I went about my business. I walked away for a few minutes and came back to a phone that just sat at the boot screen. I let it sit for about an hour, thinking that was some how normal. After an hour, I hard powered down and it came back to the same screen. I have rebooted at least 50 times now with no luck.
I can boot into fastboot, but not recovery. If I try to go into recovery, it goes to the boot screen and sits there. I have tried to switch partitions, it is stuck on A, without luck. The bootloader is locked and I can not remote unlock it via fastboot. Nor can I manually change the boot partition to B.
I have an open ticket with Essential, but they have been blowing me off and basically told me I'm out of luck since I was in their Beta program. They told me to go to XDA. A$$wipes! Any help you can offer is greatly appreciated since I'm stuck with a bricked phone and having to use an old iPhone since I cannot be without a phone.
Exact problem happened to me last week and a very helpful XDA member saved me.
Just hook up phone to pc by adb, type in 'fastboot devices' (while in fastboot mode) and install 7.1.1 os again. You'll lose everything but at least you won't be softbricked anymore.
Edit: sorry, just read you do not have unlock bootloader so this probably won't work.
Have you tried wiping data in while in fastboot? That might get it to boot.

You don't need an unlocked bootloader to sideload the install (following the BETA instructions: https://www.essential.com/developer/beta-builds
Since you can use fastboot, it looks like you have working ADB environment, so you should be able to follow those instructions. The STOCK recovery works very differently than TWRP, so make sure you follow those intructions, particularly the "Apply update from ADB" part. It took me a while to understand this, especially because the type on the screen is so tiny, I couldn't tell any words were changing.
I'm having the same issue (stuck on the boot logo "powered by android" screen) and I can get into fastboot mode, however if I try to go into recovery mode it just gets stuck on the boot screen again.
When in fastboot mode, the device state is "locked" is there any ways to get this fixed?
You could try: (you will lose all your data)
fastboot -w
fastboot reboot

update im still stuckk
Have you tried booting to bootloader and mounting /system?
This is obviously corruption of the firmware, and has nothing to do with wiping userdata. Download the full firmware and flash all of it through fastboot.
I also have my phone stuck The bot is closed and I can not do anything

Was this your first time flashing TWRP? It sounds like you flashed the image to boot and not recovery...
fastboot flash twrp.img
Will result in the issues you stated, basically a "soft brick" condition.
fastboot flash recovery twrp.img
Is the correct format for the command. Without specifying the partition to flash, fastboot assumes it needs to go to boot... And if you don't have the original boot.img file it us unrecoverable.

Nope, not first time flashing twrp, been doing it for a few years.
The rom is bad that I installed. It makes twrp freeze as well and shutdown.
But I followed this guide https://forum.xda-developers.com/moto-x-style/general/xt1575-moto-x-pure-edition-factory-t3704142 and then reflashing latest twrp and restoring stock nougat rooted image backup I made worked.
