Fastboot loop after install vendor firmware - Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe

Hey,
I flashed new vendor EU firmware with android 11 then reboted phone it boot normally to system "Evolution X". Next I downloaded update and after click install it rebooted to fastboot.
I can't boot to recovery because it's always reboot to fastboot. So tried to install again OrangeFox recovery but after usage command "fastboot reboot recovery" I got message "fastboot: usage: unknown reboot target recovery" and it's still rebooting to fastboot. Tried Power + Volume UP.
Any solution for that?

Okay, if someone will have simillar problem just download MIUI Official ROM - Fastboot version:
https://xiaomifirmwareupdater.com/miui/raphael/
Then unpack it and flash dtbo.img - fastboot flash dtbo dtbo.img
And now everything should works fine.

boot problems 5.5.22 Mi Note Pro

Hello,
my Mi Note pro worked fine at the beginning, running the latest stable ROM.
I then installed 5.5.22 Developer ROM which also worked fine.
For some reasons, I then downloaded "Minimal ADB and Fastboot" and flashed the recovery.img - since then the device does the following:
* does not boot beyond the Mi Logo
* can boot into Fastboot mode
* cannot boot into recovery mode (volume up + power) - it once did this somehow, as I saw the screen flickering and could see the 2.0.1 recovery version in red below
I then flashed the device with the 5.5.22 Fastboot ROM, which worked fine. But the device still does not something different then the three points above.
I then updated the device with the Mi PC Suit to the satble and also again Developer ROM which worked, but the deivice still did not boot.
I then flashboot flashed the 5.5.22 recovery and boot.img, but again, nothing changes. The deivice can boot into Fastboot, but not into recovery and also does not boot normal.
Any suggestions, what I could do? I tried so far absolutely everything, but maybe I forgot somethign important.
regards,
JJ

There is no working recovery other than what comes from official MIUI firmware, it is possible the bootloader refuses to load unauthorized firmware. You are going to probably need fastboot ROM images

Do you have fastboot and frp unlocked?
Yes it is frp unlocked
Check my answer in this thread.
Hope it helps! And if it does, please hit the Thanks button.
please try this :
- download full update rom for your device, extract the .APP files using HuaweiUpdateExtractor
- boot into fastboot by press and hold Volume Down and plug in usb cable into your pc and your phone, hold it until it boot into fastboot
- do this :
fastboot flash kernel kernel.img
fastboot flash ramdisk ramdisk.img
fastboot flash recovery_ramdisk recovery_ramdis.img
fastboot flash recovery_vbmeta recovery_vbmeta.img
fastboot flash recovery_vendor recovery_vendor.img
fastboot flash system system.img
fastboot flash vbmeta vbmeta.img
fastboot flash vendor vendor.img
- reboot your device and hold Volume Up and Volume Down to get it boot into eRecovery and do Wipe Cache Partitions and then do Factory Data Reset, and reboot again
- let it boot normally, and see what happen next, i can't remember for sure because it's been so long i unbricked my Nova 2s with this method. there are 2 possibility, you'll boot into system normally, or it will boot into eRecovery again and there is an option Download Latest Version And Recovery and you can choose that, of course you should have connection to internet via wifi.
please report back if you have difficulties.

Hi, please don't ask me how I did this but I somehow hardbricked my phone, Model: LLD-L21
currently status is literally a brick, screen doesn't even turns on, holding keys doesn't lead to anything, Only thing I have is fastboot command, in fact when I connect my phone to PC, I hear connecting sound from windows and fastboot drive is up, (even in bootloader the screen is off) so what I have:
FRP is unlocked
Bootloader is unlocked
last installed firmware was EMUI 8
working fastboot
literally nothing more, how can I unbrick this brick my own?
[update]:
I tried your solution but at last part, vendor cannot be flashed (Command not allowd) and I guess no hope

How you did FRP unlock?

confused, cannot flash TWRP

Strange, maybe I am missing something but not aware of what...
I've been on Revolution OS and as being curious I gave Android Q a try....means, I flashed "Q" successfully yesterday -through Mi flashing tool- but wasn't happy at all, therefore I went back to Global Dev (again via Mi Flashing tool) to reinstall Revoultion.....Regardless of which TWRP version I' am trying to flash, even after Fastboot is indicating a successful TWRP flash I am not able to access the Recovery. Trying to use adb reboot recovery ends-up in the stock recovery....also fastboot boot recovery.img dosn't help....
even trying to flash the TWRP version I used to install Revolution recerntly does not work.

What I've found is normal commands to boot into recovery do not work for this phone. Boot into fastboot, flash recovery then use volume up and power combination to boot into recovery. Hopefully that will get you back in.

ROM I used

The command I used
fastboot flash system system.img
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash cache cache.img
fastboot flash cust cust.img
fastboot flash dtbo dtbo.img
fastboot flash dummy dummy.img
fastboot flash logo logo.img
fastboot flash metadata metadata.img
fastboot flash misc misc.img
fastboot flash persist persist.img
fastboot flash vbmeta vbmeta.img
fastboot flash vendor vendor.img
fastboot erase userdata
fastboot flash userdata userdata.img
fastboot reboot
Finally I found a TWRP version that is working (3.3.0-0423 by wzsx150 -thx mate!) and got back to Revolution OS!!
Thx also for your support!

Can't Access Recovery or Device, only Fastboot

Hello,
I deciden to install Android 10 Beta 3 then install a custom rom. I succesfully installed Android 10 Beta 3, and tried to install Magisk as told in here. After the patched boot.img step, my device stopped booting.
When I press Power+Volume Up or Down, it always goes to fastboot mode. I can't boot into recovery from fastboot, I can't boot TWRP from fastboot. I tried:
fastboot oem reboot-recovery
fastboot boot twrp.img
fastboot flash recovery twrp.img
As shown in the image rebooting into recovery always failing. What can I do?
same problem here... were you able to fix it?
You might have to use the QFIL method to get your phone going again. Remember you MUST backup the EFS partition and anything associated with your phones imei and SN

这两个可怕的重锁码吓了我一跳,以为手机没电了。幸运的是,我找到了解决方案。你可能需要找个老股rec,跟着视频操作,不用拆机,重点解压。进入adb文件夹,生效

Hey guy,
My phone was running the rom "UL-ASUS_X00QD-ASUS-AOSP-17.0615.2005.25-1.1.1-user.zip" (downloaded from Asus Web). I tried to install the TWRP ver 3.3.1 unofficial and my phone was stuck on the fastboot mode only.
After a lot of searching on how to fix the issue, I didn't change anything and almost gave up, until I've read this thread.
My Asus Zenfone 8 flip is STUCK in CSC FASTBOOT MODE PLZ HELP!, RAW FIRMWARE ANYONE???
These are what I did to get the phone into the recovery mode:
1. Extract the rom zip file that my phone was running on.
2. Copy the file boot.img to adb folder.
3. On PC, at adb folder enter CMD, connect the phone then type
fastboot -w
fastboot flash recovery recovery.img
fastboot flash boot boot.img
fastboot reboot recovery
4. After that, my phone can be booted into the recovery mode.
Hope you can solve the same problem as me.
Bye bye ...

Help| Can't boot

Hi,
I have Carbon ROM with Android 10,
I wanted to flash Bliss ROM, and it says that I need a rooted device,
So I've downloaded Magisk and follow the instruction, created a boot.img and flashed it in fastboot, then I did the same only with twrp recovery & Magisk, flashed it and now it is wiered and I'm not sure what is the problem,
I have fastboot BUT when I try to perform any command, it shutsdown and preety useless, I've tried from PC, if I try from MAC, I can boot into twrp but every operation is causing the tablet to reboot.. So I can't even flash a stock ROM,
In PC, the recognized Android device (When in fastboot mode) I update it's driver to Android bootloader device
Now, fastboot says: "fastboot: error: cannot get boot partition size"
tried:
fastboot flash:raw boot boot.img
fastboot flash:raw recovery twrp.img
How can I solve it?
Thanks !!!
Did you also try
Code:
fastboot flash boot boot.img
?
I can boot into twrp but every operation is causing the tablet to reboot

I didn't understand the problem, I think.
You flashed a patched boot.img and your twrp recovery isn't working? Like if you press a button, it just reboots?
I have fastboot BUT when I try to perform any command, it shutsdown and preety useless

If you do
Code:
fastboot devices
it also doesn't work?
Or only if you flash a img?
