Still no root

Hello fellow huawei p8 max owners. I still haven't been able to root my P8 Max. My computer is running windows 10. Is there someone who can put the files here that are needed for a succes full root procedure? Thank you in advance.
I'm running B026........
Successful Root
I have achieved root on both of my P8 Max devices (DAV-703L) following this process posted by rowihel2012 (and thanks to dodzs for posting the root tools):
http://forum.xda-developers.com/android/help/q-root-p8-max-t3152663/page3
1) Get your unlock code to unlock your bootloader (I am running Windows 10 and had no problem with adb commands after installing HiSuiteSetup_2.3.55.1.exe (http://consumer.huawei.com/en/support/products/downloads/p8max-en.htm)
2) Load TWRP (after completing "fastboot flash recovery recovery.img" remember to remove your USB cable. Then hit the power+volume up. When you see the Huawei logo release the power button and continue to hold the volume up button until you see TWRP.
3) Load the UPDATE-SuperSU-v2.46 file in the root of your sd card. Boot into TWRP using power+volume up method. Once in TWRP click Install and select the zip file and bingo...you have root.

I have tried fastboot in Windows XP with my Huawei P8 MAX, without success...
I have tried
UniversalAdbDriverSetup6.msi
Huawei_Mobile_Driver_v1.0.zip
even the Huawei USB Driver 1.6.10.08
There is no problem with starting my Huawei in proper mode (with USB cable connected it have been started with Vol-up and power)
In control panel/devices I DON'T have question marks (?) devices now, after driver installation it all looks ok.
But the "fastboot devices" (minimal_adb_fastboot_v1.3_setup.zip) shows nothing
and "fastboot device" shows <wait for....>
Of couse I have the unlock number from https://emui.huawei.com/en/plugin.php?id=unlock&mod=detail
Which version of drivers from which site is ok for Huawei P8 max and Windows xp ?
Please help !!!

SOLVED
Magically "fastboot devices" has showed my P8max (after restart probably)

you need to reinstall your adb. your commands will start working.
if you are using windows then go device manager and uninstall adb driver, then click search and it will reinstall the adb. after that try again the commands. thats what i do always when i stuck in that situation like yours.
or simply try another computer for adb

What happened?
For some unknown reasons, I brick my phone too after flashing magisk on stock ROM 10.3.7. At first I'm getting bootloop. Then decided to just drop magisk and reflash stock ROM again. Then I encountered an error. Hopefully this method will work.

Hello. I have a redmi note 7 pro that died after updating to version 10.3.13 global version. it seems that this version came with antirollback. the phone came with the bootloader unlocked and I had installed twrp and root on it, and I didn't manage to associate it with my account. after updating, I tried to install an older version because I could not install twrp but unfortunately I left the check all and lock checked. so I opted for a dead phone with a locked bootloader and that didn't let me install an older version than 10.3.13. unfortunately the phone I think is the Chinese version and had an unofficial version installed by my global seller. after installing version 10.3.13 it tells me that this version of miui cannot be installed on this device. can anyone help me revive him?
My phone got bricked redme note 7 pro ,I tried with flash tool echo mismatch it's getting error what is the problem which rom i need
Anyone can tell how much service center charges to unbrick via edl mode?
