[Huawei P9 Plus Guides, News, & Discussion] thomascook:
So we just managed to get our Huawei P9 Plus (VIE-AL10C00B106) successfully rooted

0.) *** if you have your Bootloader UNLOCK Code from Huawei, jump to STEP 3 ****

1.) downloaded DC-Unlocker, created a account, added 4 Credits(4EUR) to account. Device should have USB DEBUG Mode enabled and you need to enable 'Manufacture' mode: in dial pad type *#*#2846579#*#* - you enter the "Project Menu", go to "Background settings" -> "USB ports settings" and switch to "Manufacture mode". Dont forget to have your device Drivers (ADB) installed

2.) Once your P9 Plus is normal booted, start DC-Unlocker (here we tested 1.00.1299) , select "huawei phones" with "auto detect" and hit the Search-Button. Your device should be found and listed with IMEI, FW ect.

If you have entered your account details under "SERVER" in dc-unlocker, you can now use the "read bootloader" Button to get your bootloader unlock code - your Credits are GONE then. SAVE THIS CODE BEFORE CLOSING DC-UNLOCKER!!!!!!

3.) Boot your device in fastboot - screen should show "locked" as status on the white screen. Type command "fastboot oem unlock XXXXXXXX" (replace the XXXX with your unlock code from DC Unlocker)

4.) Phone Screen should show a WARNING Message and offer to press VOL UP to UNLOCK phone - WARNING, if you select UNLOCK and press PWR Button to agree, DEVICE WILL INSTANTLY RESETED TO MANUFACTUR DEFAULT

5.) Download the Root-SuperSU-v2.65.zip (DIRECT DOWNLOAD) and put it on a SD-Card

6.) Download the TWRP3.0.2_EMUI4.1_H95X File (DIRECT DOWNLOAD)

7.) Reboot your phone and re-enable USB DEBUG Mode, dont forget to ALLOW Debugging via PC if promped. Insert your SD-Card with the SuperSU Zip into your phone if not already done.

8.) RUN TWRP3.0.2_EMUI4.1_H95X, it will reboot your phone in Fastboot mode. By pressing 1 and then enter, you will Install TWRP 3.0.20. Follow the instructions, by pressing enter again your phone should reboot

9.) while rebooting, HOLD VOL UP and VOL DOWN together pressed until Phone tell you "booting", it should boot into TWRP now

10.) On TWRP, in the right Corner, you can Switch Language from Chinese to English (selectable, dont worry). Now go to INSTALL, move to EXT_SDCARD as source and select the SuperSU ZIP -> INSTALL

the installation of SuperSU may show mounting/unmount errors, but will be installed anyway.

After Operation is done, reboot your Phone into normal Mode. You should find SuperSU installed on your device now.
