So after many tries on my Huawei P9 Lite, i successfully manage to do all the things we wants ! I never wrote tutorials so please don't be rude on me
Works on : VNS-L21 and VNS-L31
- Huawei Driver installed ( Can be done by installing Hisuite from Here )
- Unlocked Bootloader ( IT WILL DO A FACTORY RESET SO SAVE YOUR DATA BEFORE )
- SRKTool Huawei ( I've re-ziped it with P9 lite recovery, get it Here )
- TWRP Recovery File ( Included in SRKTool Huawei )
- Flashable SuperSu STABLE Zip ( Get it Here )
1. Unlock the Bootloader
To unlock the bootloader, without any tools, i used the huawei website !
Here is the address : LINK (Chinese version because the English one is offline at the moment, create an account if asked to !)
/!\ Save your data before doing anything ! Unlocking your bootloader will do a factory reset !
Now fill all the informations like this :
We get our Unlock Code for Booloader, write it somewhere !
Now we must activate the OEM Unlock option on your phone, go under Settings/Developer Options and tick the "Enable OEM unlock" option. In the same menu check if USB Debbuging mode is enabled, if not do it !
Connect your phone to your computer !
Then unzip the SRKTool Huawei somewhere and launch the application ( srktoolHuawei )
Do like the Following pics !
Press Enter twice:
Select Option 1 and press Enter
Are you sure to continue ? Y
Do you have bootloader ? Of course we do ! ( The one we wrote somewhere, you remember ? )
Now your phone will reboot in Fastboot Mode :
Press Enter (again)
Write your Bootloader Code and press Enter (again !)
Would you like to continue ? Of course !
Here we go ! If you carefully followed the instructions your Bootloader is unlocked ! (Mine says Failed because it's already Unlocked ! )
2. Install TWRP !
Okay now i'll tell you how i installed TWRP in the P9 Lite ! Like i said at the start of the tutorial, i provided SRKTool Huawei with the right recovery not the one given with the utility, ( For the scecptical, i used a TWRP version for the HUAWEI G9 Youth (Chinese version of the P9 Lite))
So connect your phone to your computer and start SRKTool Huawei, Press Enter until you got the main Menu !
Select the Option 3 Install Recovery !
We got the Huawei P9, so choose it !
We want to install TWRP, Option 2 and press Enter !
Are you sure ? I guess we do ! So Y
It will reboot your phone in fastboot mode !( And if you've done everything right, you'll see PHONE Unlocked and FRP Unlock on your screen phone ) Press Enter again !
Wait a bit, and voila ! TWRP should be installed !
Press Enter and your Phone will reboot in system mode !
Now to reboot your phone in Recovery Mode, turn it off and start it by pressing Volume Key Up + Power ! This TWRP version is in Chinese but you can change the language in TWRP Itself !
2.1 Change the TWRP Language !
Now you're in TWRP in Chinese, we better want the English version !
1. 2. 3. 4.
Boot your phone in normal mode and plug it to your computer, download the SuperSU STABLE zip from HERE (don't extract it)
Now put the zip file on your sdcard, unplug your phone, turn it off and reboot into Recovery Mode ( Volume Up key + Power )
Select your SDCARD if it's not selected by default ! Select Storage -> MicroSD Card -> OK
Then choose the ZIP file you've put in your SD Card ! And Swipe to install it ! Reboot aaaaand
Voila ! Your Huawei P9 Lite is finally Rooted with Custom Recovery and Unlocked Bootloader ! Enjoy it !
( Warning ! You'll maybe get a message when you boot your phone, saying you that it is not trusted and insecure anymore, thanks google, don't worry it's just because it's unlocked and rooted ! )
