Fastboot can't detect my unlocked device - Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe

Hi I have a problem where my pc does not detect my unlocked device in fastboot. This is a problem because I tried to update from global V10.3.3.0 to miui 11 but that did not work probably because there is not the right recovery on the device. So I can not get into the recovery and I can not get into the system this would of course be no problem because I can get into fastboot but my computer wont detect my device. How can I get my 9t pro to be detected in fastboot?
My device is unlocked. I did all that some time ago and it says so when I try to boot into system or recovery.
USB debugging is on. Idk if that is still there because I did try to update the system to miui11 but it was not detecting my phone in fastboot even before I did that update.
When I connected my phone to my computer when the system still worked I could use "adb devices" and that worked
I could also transfer files and stuff when my phone was connected to my laptop
So only when in fastboot my unlocked device is not detected if it was I could get back up there.
I really hope that this is some driver problem or something. Please help
Edit:
So at this point magically the system worked again! But I still can not use fastboot

I seem to have this problem:

bricked my Mi5

Hello!
Was using 7.2.8.0 ROM out of box.
Tried to update to developer 6.5.19 but something went wrong. Now only fastboot/recovery works. Can't do fastboot oem edl - tells me it should be unlocked. Same problem with fastboot flash system - tells me device is locked. Me PC Suite doesnt recognize device at all. Tried on my laptop and PC. Help please.
any1?
Are you logged into your Mi Account on the phone? If yes I guess you have to wait for bootloader unlock and then flash rom with fastboot.
I logged in last time my phone worked.
The unlock procedure uses my phone and it cannot start so I will be unable to unlock it since only fastboot and recovery modes are available.
any other suggestions?
apply for the bootloader unlock code with your mi account (use other phone while you fix the xiaomi), wait for the unlock approval sms code, its tooks like 7 to 15 days, then download the software for the unlock bootloader process, loggin with your approved mi account, put your phone in fastboot mode, connect it to the pc press start and thats all (no need to boot in normal mode for unlock), you should have your bootloader unlocked and you will be able to enter in EDL mode and flash again the rom.
P.D. Sorry for my bad english

That's pretty much exactly what I wrote in my post XD
Have you try to flash using MiFlash?
You can download it from here
My friend also encounter this problem and what he did is:
1. Use a fresh installed notebook with Win 7
2. Use MiFlash to flash the image file.
Image file can be downloaded from here.
It should works with locked bootloader as you are flashing the stock image.
Please give it a try.
Any luck alien2k1?
I'm in the same boat, bricked Mi 5, can access bootloader and TWRP recovery, but can't turn phone on because of bootloop. I want to use Mi PC Suite to flash the fastboot rom. But, when my phone is in Fastboot mode, and I connect it to the computer with the micro USB, it says "Try connect in normal mode first then switch" . But my phone is stuck in a bootloop and I can't "connect in normal mode first." It can't detect my phone in Fastboot mode, and it can't detect my phone in "normal mode" because I can't turn the phone on in normal mode because it gets stuck in a bootloop.
My bootloader is unlocked.
I can't open MiFlash either and I can't turn on USB debugging on the phone because its stuck in a bootloop. What should I do?

If you're on unlocked bootloader and can access fastboot, why don't you use the fastboot packages? There's a script provided by them in the fastboot downloads to flash everything

I am in the same ****in situation, have you solved your issue ?
thanks
Looks like everyone is in the same boat here. I have tried several methods but the Redmi Note4 wont work. Mi PCSUIT wouldnt detect my phone either. Fastboot wont work with the message "Try connect in normal mode and then switch." I am wonder what is the sure and final solution to this problem. The issue is flashing all over the internet but no specific solutions yet.
If you have any working solution, please share. Thanks

Fastboot not working

Hey guys,
I have a problem while trying to flash TWRP on my Xiaomi Mi5. TWRP was installed earlier and worked completly fine with flashing custom ROMs, flashing OpenGAPs or rooting the device but now for some reason TWRP got lost and the standard Xiaomi recovery is on the device again. Installed was MIUI 8 in the Dev-Version (weekly patches) for the last half year and was the last ROM flashed with TWRP.
And now comes the problem when i try to install/flash the twrp image via fastboot: If i reboot the device in fastboot mode it shows the following behaviour:
1. It show the fastboot logo on the screen for about 10-30 seconds before it reboots automaticly (doesn't matter if i connect it via USB before or while it shows the fastboot logo)
2. While it shows the logo on the screen and it is connected via USB it's not showing up in the console when i list the all connected fastboot devices
I can still use the devices standard recovery and the installed OS, just the fastboot part seems to be brocken. Am i missing a driver on my computer or something?
Has somebody else an idea how i can solve this automatic reboot in fastboot mode?
Edit: If this Thread belongs into another catagory, i apologize
Make sure minimal adb and fastboot are installed in your pc. After that, enable usb debugging from developer options and connect with your pc and let it there for a while to install drivers on your pc. Then go to twrp and your phone should no longer reboot after your connect usb. Flash twrp here.

ADB and FASTBOOT installed -> checked!
USB-Debugging enabled -> checked!
Windows installing drivers automaticly -> unsure. Windows didn't installed anything it just notified me that there is a new USB-Device (Device is also showen as ADB-Device and appears in the list of connected adb devices)

To that: TWRP is not installed on the phone anymore. I just have the standard xiaomi recovery where i'm not able to flash a .zip or something. I can just wipe all my data there
The reboot behaviour also appears if i switch to fastboot via "adb reboot bootloader" command while spamming "fastboot devices" to check if it appears before it reboots.
The standard recovery is usable as it should be without any reboots only the fastboot mode seems brocken.

Weird. Everytime this sorta problem happens to me, its because windows didnt have the drivers installed after you connect your pc with debugging enabled. So thats the only troubleshooting i did to fix things. And yeah it did show me drivers installed correctly after i connected phone with debugging enabled. Maybe for some reasonn those drivers arent being installed to windows. Give it more time maybe? [emoji23]

I too have the same problem..****
Install MiFlash on your PC and try again, the device will show up correctly on fastbook devices command. It was a USB drivers issue in my case.

[SOLVED] Mi a2 bricked, fastboot not detected

After installing the latest Pixel Experience, my phone keeps rebooting to twrp logo, and fastboot can't recognize device. Please help.
If the solution is edl mode, Is there any possible way to go into edl mode without disassembling device?
Edit: My pc magically able to recognize my device, then i boot to TWRP, wiped everything (except internal storage), flashed PE. Change slot then flash FBE disabler and magisk, then my phone is booting normally.
i'm having the same problem too. i believe my phone's partitions got corrupt since the log says that /sys/class/android_usb/android/0/state doesn't exist. can't really take my phone to a service center since, well, we don't have any of those in our vicinity
Fastboot oem edl. Try that and then miflash on fastboot

can't really do that since my pc doesn't detect the phone. i've tried edl but my pc doesn't detect the phone either.
Device not detecting in fastboot mode
i tried flashing with edl still device is not detecting with fastboot mode

Mi9t pro stuck to flashboot but doesnt get detected

So for some reason after wiping my phone with twrp my phone got stuck on fastboot. It does not boot to recovery nor does anything else other than reboot to.
Problem is that when i connect it to the pc it doesn't get detected by the xiaomi flash tool... Tried booting into edl and it detects it just fine but can't really do much there since I don't have a authorised xiaomi acount.
I had a orange fox and unlocked bootloader obviously. It's pretty weird that it doesnt get detected by the computer since it is in fastboot and I have all the drivers needed... Any ideas?
Thanks in advance

my phone wont turn on after i Unbrick it with abd

after i typed the last command (fastboot reboot )the phone wont start up again its like dead no light or anything is showing i connect it to a pc i hear the usb sound but nothing appear
i tried typing adb devices but nothing is showing
is the rom i install is bad or somthing and how do i fix it and turn it on at least into fastboot
Unsuccessful rebooting 7+ times was supposed to switch phone to use another of A/B slots with previously booting system.
If phone is unlocked, u can try to switch A/B slots via fastboot or temporary booting into TWRP.
If phone is locked, search for TestPont/EDL flashing guide.
