Huawei p9, EVA-L09-problem with unlocking the bootloader.

Hello!
I am trying to root my phone, which requires and unlocked bootloader.
Here are the steps i have completed:
1. Got the unlock code.
2. Installed adb and fastboot drivers.
3. Installed HiSuite
4. Connected the phone to my desktop (windows 10).
Here i have to mention that the pc recognises my phone, and it is listed under devices. USB debugging and OEM unlock are enabled.
5. I opened cmd in the folder where abd is installed. Checked that abd devices finds my phone (which it does).
Here is where the problem comes in. After booting phone into fastboot (using adb reboot bootloader), i tried to find my phone using the command fastboot devices.
This doesn't find the phone. If i try to unlock anyways, it gets stuck on waiting for devices. I tried the same steps on a laptop (also running windows 10) and the problem stays the same.
Help is appreciated.
EDIT: solved the problem by using a windows 8 installed laptop.

Uninstall HiSuite, it may interfere with the phone's connection. It is not used when unlocking/root.

Thank you for your reply, but this didn't work.
To add a detail, the reason i installed HiSuite was, because in fastboot mode it says:
"Please install HiSuite and connect your phone to your computer with an USB cable.

You can try using this tool to unlock bootloader:
http://forum.xda-developers.com/p9/development/tool-srk-tool-huawei-bootloader-root-t3374068
I personally used this and worked flawlessly, make sure to get the latest version of it if you do.
If you are in fastboot&rescure mode, try the command "fastboot devices" and see if the device is detected, if not try unplugging and replugging phone

Will try the tool when i get home from school, but fastboot devices doesn't detect my device.
EDIT: The tool didn't work. It is stuck on waiting for device.

Fixed the problem by unlocking on another laptop (has windows 8).

adb won't recognize phone

I am trying to unlock the bootloader of my g5S+ se
Installed drivers
Turned on USB debugging
OEM unlock
Right click and type adb devices in the command prompt window nada. Devices found
Downloaded the USB drivers from the unlocking page at Motorola. In device manager checked no issues with the driver so what am I missing guys

Have you installed adb?

I can see fastboot devices but not adb devices

Fastboot not detecting

Hi,
I have a problem with my device, when I connect it to pc adb can see it easily but when i type "adb reboot-bootloader" it boots to fastboot but my pc doesnt see the device anymore and there is no device detected when I use "fastboot devices" command.
It used to work before windows update but now it does what I said.
Is it because of the drivers? if so can anyone send me a link to proper windows 10 drivers for china k20 pro.
I'm not rooted and no twrp. Just the stock firmware (10.3.16).

I had this problem in my Nokia 7 Plus, then i used and installed "minimal adb and fastboot" file which detected my phone in fastboot. It installs in program file with a folder named "minimal adb and fastboot"

You need to enable "USB debugging" in the developper options

It is enabled.
And ill try with the minimal adb option
Update:
Still not working

I have same problem, there is no way to recognize my 9t pro in fastboot mode... i cant do anything

First it should be intel pc
Try to install Xiaomi drivers and adb
Boot to recovery and fastboot while connecting to usb to install the drivers
Then check again

Did anyone solve this? I'm experiencing the same issue. ADB works fine, but no device is listed at all (device manager in win7 or syslog in linux) when connecting the phone in fastboot mode. It's like it wasn't physically connected at all.

Try changing ports / connect to another pc
Install proper drivers .
Is your bl unlocked now ?

Got it to work under win7 with great help from this post.
What I did was:
Update to the latest miui version (to MIUI Global 11.0.3, as prompted in system settings, I hadn't bothered to update because I just want to throw miui out)
Disable OEM unlock
Reboot
Enable OEM unlock again
Reboot into fastboot
Then the phone showed up as an unknown device in Device Manager
Right clicked the device and updated the driver, chose to search for drivers in the miflash_unlock-en-3.5.1108.44\driver\xp-win7-win8 folder
The device now lists as an Android Bootloader Interface device
And now:
$ fastboot devices
e150445 fastboot
MiFlash unlock detects the phone, and I could proceed with unlocking. Still have to wait though. Tried the older-version-trick as suggested here, but that just told me to update to the latest version. Guess I'll have to wait a week then...
Hope this helps someone. This is the most tedious unlocking procedure I've encountered so far...

Moto G5S Plus usb problem : adb no - fastboot yes

Hello ,
I encountered a very weird problem with the usb port.
I have turned on USB-debugging but my phone doesn't show the connection dialog that indicates the state of phone connection.
I experienced this on a windows-10 machine and on an Ubuntu driven machine.
Cables are ok, drivers are ok. I tried to connect an old moto g 1st edition and the rsa dialog showed up and then I could choose if I wanted to recharge the battery or make an another type of connection.
Adb bridge also worked fine with my old phone, so I am sure the computers and the cables are fine.
So I gave an last try to my XT1805. Did a reboot into fastboot mode by using the start and volume down buttons, and to my big surprise the fastboot commands worked fine.
Well after that booted back in normal mode, backed up everything a did a factory reset.
Unfortunately that didn't solve the problem, adb doesn't work but fastboot is ok.
Hope somebody con give me some hints to solve the problem.
Forgot to state that the phone is on Oreo updated by OTA to the most recent version.
Regards

You need to use adb device, in order to use the command while the device is on.
For bootloader:- fastboot (command)
For power on device:- adb (command)

Forgot to state that 'adb devices' does not show any device connected.
As I said it's not a problem on the computer side as other Android phones are accessed correctly in ' adb shell'.
