Hello, I've tried it all.
I have a P8 lite 2017 and I would like to root it for free.
I can't get the fastboot unlock code.
I can't manage to install android 5. even with HW_android_stock_5.app (2.6 G)
I only can downgrade from androi 8 to android 7 from HiSuite.
The dload/UPDATE.APP methode always failed at 5%, whatever the app or the source it comming from.
I've tried with or without SD card. I unplug the phone at every downgrade attempt.
I've tried erase data on P8, wipe cache, erase and format SD card.
Can someone help me please ?

P8 lite 2015 here... tried every single link in this thread, none worked.
Actually I'm not sure if the phone even tries to flash the UPDATE.APP
I turn it off, then with the sd card loaded on the tray, vol + and - while powering on. Just getting the EMUI reboot/wipe factory/wipe cache screen.
I'm about to throw the phone away wtf.

Last resort.. I'll flash TWRP using testpoint.

The method is to pull the unlock code from the phone. For this we will need root. You can only root for a blocked bootloader on Android 5.0. So:
1. If you do not have Android 5.0, do a downgrade.
How to go on Android 5.0 (downgrade):
1. Download Rollback and B170,
2. Unpack the rollback and upload update.app to the dload folder on your phone,
3. Turn off the phone, then hold vol +, vol- and power. The phone will install a rollback
4. Unpack B170 and put in the dload folder on your phone,
5. Turn off the phone, then hold vol +, vol- and power. The phone will install B170.

2. Root your phone with KingRoot,
3. Download Minimal ADB and fastboot, connect the phone in USB Debugging mode and start the ADB,
4. Enter the command:
Code: 
adb shell
And then:
Code: 
su -c "grep -m1 -aoE 'WVLOCK.{14}[0-9]{16}' /dev/block/mmcblk0p7 |grep -aoE '[0-9]{16}'"
You will receive the unlock code. Copy it.

5. Press ctrl + d and Enter:
Code: 
adb reboot bootloader
6. Enter:
Code: 
fastboot oem unlock ****************
(paste your code in place of the stars)


And that's it. You have the bootloader unlocked :)

    I used Kingroot to Root my phone on EMUI 3.1, but I found that I can't flash anything in the "UNLOCKED" bootloader.
    So I guess, we need to re-unlock it after getting Root by using Kingroot. Maybe we can use this way to get unlock code on a Rooted device:
    Open terminal and type "su"
    and type the following command one by one:
    Code: 
    cd /storage/emulated/0
mkdir -p PartitionBackup
cd PartitionBackup
dd of=/storage/emulated/0/PartitionBackup/nvme if=/dev/block/platform/hi_mci.0/by-name/nvme
dd of=oeminfo  if=/dev/block/platform/hi_mci.0/by-name/oeminfo
strings nvme | grep WVDEVID -B 1
    The method comes from: https://blog.csdn.net/autohacker/article/details/50715639
    Maybe you can try it.
