Installation:
Root install method 1 (no TWRP)

• Reboot phone into bootloader mode
• Download boot.img to PC and fastboot flash with: "fastboot flash boot rooted_b378_boot.img"
• Reboot phone back into system
• Install phh's SuperUser app from Play Store
• Install JRummy's Busybox Installer and install to /vendor/xbin

Root install method 2 (with TWRP)

• Download boot.img to phone (Internal Downloads or External SD)
• Use OldDroid's TWRP: https://forum.xda-developers.com/p9/development/twrp-t3565703/post71244945#post71244945

Note: To get AdAway working, go to Preferences, then scroll down to "Target hosts file" and set it to "custom target". Then set Custom target to "/vendor/etc/hosts"

No responsibility if this doesn't work/breaks your device/eats your cat etc. - make sure you backup your data and have a backup boot/recovery image handy

This is not systemless root yes? No OTA support?

Yes this is Systemless, OTA should be fine - I've manually flashed OTA via dload but not tested normal OTA upgrade

SuperSu does not currently work on the P9 with Nougat, partially due to lack of loop mount support in the kernel. Kernel sources are needed to rectify this, so I encourage people to email Huawei asking for their Nougat kernel patches.
PHH is not perfect (some apps don't work fully) but it's the best we have right now

ohh okay thanks for the info and also the work, i guess im waiting till the fully working method is out.
I've heard that they will relase the source near this month or the next when they finsh updating every p9

 

[svardman]

Is it possible to use this prerooted boot.img for l19 honor 8?

 

[aico60]

No. It's for P9, Honor 8 isn't P9, right?

Thank you for the guide, everything worked as described. I've got my P9 with c432 b378, rooted and TWRP installed.

By testing so far, RootChecker, AdAway (v3.2), Titanium and Reboot (to boot into TWRP or fastboot) all work fine with this phh's SuperUser

PS: It's possible to install Chainfire's SuperSU instead, and Viper4Android works too, see e.g.

Hi all, is that ok to flash on my current P9 L09C432B383 ?

The stock and pre-rooted boot.img states its form .378 but would it be ok on .383?

I dont know how to get root on it currently...
