What say the device manager, which driver is installed when the phone is connected? Other usb cable? You use a hub or usb 3 port? More ideas I don't have in the moment

I don't own a hub.... my PC has both USB 2.0 and USB 3.0 neither works... and the drivers just says winsys microsoft driver. but the device's name is showing the phone's name in device manager.. but it's not showing as an android device just a USB device

I do exaclty what the video says. Pressing the volume + and volume - together only redirects me on test mode. Do you know what else i can do? I want global stable back..
If your phone is redmi note 3 pro, aka with qualcomm cpu, follow this post : http://en.miui.com/thread-235865-1-1.html
if it is with mtk cpu, follow this post: http://en.miui.com/thread-279784-1-1.html

in ADB with USB-debugging on you can write "adb reboot edl" in command promt and it should make your phone reboot to download mode.
download mode is the screen off and the LED is just blinking red.
Flash with MiFlash the rom you want?
If all drivers are installed on your pc(adb&fastboot) open adb cmd tool and type : Adb reboot edl
whith your phone on

I cant because phone isn't recognised from miflash. I can only enter fastboot mode but cant flash with locked bl. :/
Also reboot edl doesnt work because pc doesn't recognise my phone.
it's not clear what "not recognize your phone" looks like, but let's try these simplified steps.
prerequisite: your phone is redmi note 3 pro (qualcomm cpu), windows 64bit, mi flash version 20160401, you've downloaded fastboot ROM.
step 1 install mi flash on your pc
step 2 reboot your pc
step 3 enable usb debugging on your phone
step 4 connect your phone to your pc
step 5 in command windows, run adb devices
step 6 authorize your pc on your phone
step 7 in command windows, run adb reboot edl
step 8 launch miflash
step 9 choose rom
step 10 flash
Check device manager in your pc and report back on whether it shows your phone under portas as Qualcomm 9008 port or 900e port (try and enter edl mode with the button press trick).

By saying my pc doesn't recognise the phone i mean that when i have the device powered on an then connect it to the pc, nothing happens. its like connecting the phone with a usb cable and not connecting the other side with the pc. Like the pc isn't powered on. That's why i can't run adb devices and furthermore reboot edl. Also i can't access usb mode in 6.5.12 stable dev rom, through settings and every app that i checked. Its like the usb mode selector app crashes. sorry for my english... i hope you understand me

while, did you follow what I've written?
or maybe you can try these first: factory reset your phone, then when you connect your phone to pc, you should use the original usb cable coming with your phone, do not use other usb cable even it worked for other phones.
then follow steps I've mentioned.
if successful, after step 7, you should see this in device manager windows.

Thanks for replying. My phone finally decided to be nice and when I connected it to my USB 3.0 port on my laptop and powered it on just installed mtp drivers and finally worked like a charm. It charges it can be recognised by PC. I installed global stable ROM now and I am fine. thanks for your time.

It seems to be a driver issue, installing MI pc suit will install all needed drivers.

Redmi Note 3 Pro ist not recognized

Hello Guys,
I would like to flash a Redmi Note 3 pro with twrp.
The problem is it is not recognized by PC. It's not even showing anything in device Manager.
I installed usb drivers from Xiaomi, I booted to Fastboot Mode and connected the Phone to the PC. Nothing is happening. No device ist showing in device Manager.
I tried 3 different USB cables and also to connect it to a notebook instead using my PC. No Chance.
Then I tried to connect a Redmi Note 4X in Fastboot mode and the same happened. IT IS Not recognized and the device manager don't show a new device.
Both phones are officialy unlocked.
Anyone who faced the same problem and can help

Hi, so you have tried 2 PCs, 2 phones and 3 cables. I think you missed it in the Device Manager. Please connect your RN3P phone in fastboot mode and run http://www.uwe-sieber.de/usbtreeview_e.html then do File/Save full report, and post it here. Alternatively, run any live Linux and post lsusb output.
Thank you for your reply.
As it seems I can´t post links because i`m new and when I try to post the report here it says I can`t because it has more than 30000 caracters
But as I said it won´t be recognized. Both of them won`t.
When I connect them in working mode I can´t even access the data like pictures etc.
One of the 3 usb-cables were originaly packaged as I at first suspected the usb cables were faulty.
But now a friend of mine come by and I tested to connect his Redmi note 4x and it is working. The only difference is that he has miui 8 and I have miui 9 from xiaomi.eu.
So I am out of ideas now. The only I can imagine is that both usb ports on the smartphone are ****ed and therfore it won´t connect properly.
Charging is no problem by the way
Bro you have to setup adb drivers perfectly a single error in setting up leads error but no worry it would not harm your device....
So first of all setup adb driver from the given link it will show you how to setup adb driver
Then go your processor of setting up twrp.
If you need any help on setting up twrp just reply on it....

Phone exits fastboot after launching MI Unlock Tools

Hi guys, I just got myself a Poco F1 and I was thinking about flashing it.
So first I have to unlock the bootloader right? I had OEM unlocking and USB debugging enabled, installed the USB driver and unlock tools and
was ready to unlock.
Booted my phone into fastboot and i noticed that every time i launch the unlocking tools I get kicked out of fastboot, and when i boot into
fastboot again, the PC stopped recognising my phone.
Anyone knows why this happens and what can i do to unlock my phone? I followed the steps closely and tried both USB 2.0 and 3.0 slots.
Any help is appreciated.
its seems like driver issues, you must install
1. miflasher (latest) it comes with qualcom drifers , and it prompts you to install
2. miui pc suite (recomended)
3. i also installed TOOL_ALL_IN_ONe ( https://androidfilehost.com/?fid=1899786940962603435) because windows (7) wasn't recognizing my poco / (install only drivers,) ( xda ref https://forum.xda-developers.com/android/software/tool-tool-one-driversunlocktwrpfactory-t3358711 )
4. I am assuming that you have passed the 72hours of waiting time and your miui is sim verified and your miui account has unlocking rights granted , if all are YES then proceed opening the UNLOCKER app and signin to the same MIUI Account and connect devce in FB mode and proceed!

Thanks for the reply.
I tried installing miflasher and miui pc suite and unfortunately it still didnt work.
I can see my device in adb fastboot devices but as soon as i launch mi unlocker my phone will exit fastboot and i wont be able to see my phone in fastboot devices again until i restart my PC.
And it repeats again and again...

1. different usb ports
2. different cables
3. different windows user account
4. different version of windows
5. different pc (perhaps my office/cafe pc/ or friend's pc)
6. different older/newer version of UNLOCKTOOL
7. combination of 6 with (1till5)

I have same situation with my personal laptop(Intel i7 based). After 2-3 reboots (from starting Mi Unlock), it will not stay in fastboot even for 5 seconds even if I don't use Mi Unflock / Mi Flash, no matter what port (USB 2 or 3) I use. I used my office PC, & connected to USB 3 port (to test) to my surprise I could unlock the phone using Mi Unlock & use Mi Flash to flash MIUI 11 from fastboot even though I connected to a USB 3.0 port.
I just had the same issue and realised both my Ryzen machines were refusing to work. then i plugged into an old sony i3 laptop and voila it unlocked instantly - i would suggest using another machine entirely. preferably an Intel since this seems to be repeating issue.
Or get a USB 2 hub, go thru that and see if it works.

I doubt it would, especially If it doesn't / didn't work with onboard USB 2.0. In my case I could unlock & flash fastboot ROM using USB 3.0 port on my office desktop (i3 & gigabyte mobo) while I couldn't get it to keep it in fastboot mode for couple of seconds using USB 2.0 port on my laptop (i7 based & even after a clean windows 10 install). Better for him to try another Desktop / Laptop.
I fixed it with this https://forum.xda-developers.com/attachments/howto_driver-zip.2480396/

Mi A3 not recognized when connecting through usb, cant unlock bootloader (Windows /Linux)

Hey everyone
I'm trying to unlock the bootloader on my Mi A3 (M1906F9SH running stock A11), but for some reason my computer (Windows 10) isn't recognizing it. It doesn't even show in device manager. "adb devices" doesn't identify it as being connected either. Having the phone on, in fastboot or in recovery makes no difference (in recovery it shows the "no command" error). I've tried 3 different usb cable and 3 different usb ports.
Ive tried reinstalling adb drivers, qualcom drivers, ran the 15 seconds ADB installer (again). Tried to add it as a legacy device in device manager but nothing worked.
Then I tried using Linux (sepcifically mAid) but it didnt recognized my phone either.
I recently installed a custom ROM on my poco x3 (and I did so a couple of times in the past with different phones) but it was never this difficult. I honestly don't know where to go from here.
Am I missing something?

same problem with me
i am also using mi a3 evolution x 7.2
my computer (windows 11) again and again connecting and disconnect usb.
maybe usb port has bad connection.
is usb debugging enabled?
i used ubuntu to root my mi a3 and to install custom ROM, it should show something when in fastboot mode.
