TWRP Installation / adb device not shown in fastboot / running out of ideas

[ottavio22]

Hello everyone,

I am running out of idea here while trying to install the latest TWRP for my MI9. I unlocked the Bootloader with success and installed all Xiaomi and Android Drivers. I can successfully detect my phone over adb and give commands over it. As soon as I boot into fastmode however, the device dissapears from the list and cannot be found.

While phone is on:
PS A:\Ordner> ./adb devices
List of devices attached
ee8cb08f device

While phone is in fastboot:
PS A:\Ordner> ./adb devices
List of devices attached

I restarted both, PC and Phone, updated the Drivers and changed the USB ports.
I really could use some help here. Thank you in Advance!

Edit: I am using the newest adb and fastboot Version. Also when I connect the phone while in fastboot, my PC recognizes it with the classic "device connected" Sound.

Step 6 – In the Command Window type, the following code & Press enter to boot your device into EDL Mode.

adb devices
adb reboot edl

I cannot go that far because my device is not shown

Can you use the command adb reboot bootloader to reboot directly into the bootloader ?

Yes!
However, as soon as I am in the fastboot, the device can not be found anylonger!

Drivers seem to be working fine. The cmd command fastboost devices Show me a connected device which is my phone.

I managed to install twrp on the phone. (I hope)
However, now it does not boot into it. When I press the volume up and power button it goes itnto MI-Recovery 3.0. As twrp was never installed…..Help!

Hi Fastboot is diffrent from ADB.

Fastboot commands are working if your device is in Fastboot-Mode and ADB (Android Debug Bridge) is working while your device ist up an running.

if you are in fastboot mode with your device you have to type
# fastboot devices
instead of
# adb devices

Thanks, I figured it out last night ;-). The problem is that as soon as I reboot into fastboot mode, no unit is discovered in Windows. Same on my Mac and other PC as well. ADB = fine, reboot to fastboot = no device at all...

- connect PC and phone with USB cable
- put phone in fastboot (reboot phone and then holding "Volume -" and "Power on" buttons simultaneously)
- you should see a bunny picture and an info "fastboot" on the phone
-> on some devices you will see only orange info "FASTBOOT" and no bunny
- type in "cmd window": "fastboot devices" and hit RETURN
- check if you see a number (sometimes with characters)
-> then all is fine

- if you dont see a number:
change USB port / change USB cable / use USB 2.0 / use an USB Hub / check driver installation

driver and so on…
