[Other Tools & General Discussion] pdegraaf:
After reading so many useful threads on this forum, I figured it became time to share my experiences with a very new phone with others. I used the work of others, so maybe nothing new, but even so, it took some time to find all info and adapt the TWRP imade. Using the information here and my customized TWRP image, you should be able to root this phone very fast.

I assume some experience with booting into recovery, unlocking bootloaders and flashing. Please be aware of the risks of doing this and be aware that it will void your warranty

The steps

A-Make a good backup of firmware and data

1) First step has to be to save the existing software. I used the SP Flash tool to do so. Be VERY careful with this tool, as it is very easy to brick your phone already in this first step. The tool has an innocent looking "Download only" buttom, do not be deceived, as this button is UPLOADING to the phone!!! Use the Read back function and read from 0 until the first 3.8Gb. If all goes well, you do not need this backup. Unfortunately I do not (yet) have the scatterfile for this MT6750T phone. You need the scatterfile to be able to download the different partitions. Anyway see: [TUT]MTK Android (Sp flash tool ) tutorial on XDA Developers

2) Install Magisk man from googleplay, run it and choose download Magisk zipfile. Save this file in your (unencrypted!) SD card

3) Backup your Userdata. A way to do this is the built-in Recovery rom. It will also backup properly if your phone is encrypted . You can backup to the SDcard or to an OTG usb disk.

B-Start the actual hack

4)	Unlock your bootloader look here: how-to-unlock-your-android-phones-bootloader-the-official-way in short:

a.	Make yourself developer (settings/phone/tap the image info 6x)

b.	In the developer tab choose: “Allow unlocking the bootloader”

c.	Shutdown phone

d.	Press and hold Volume UP and ON for five seconds

e.	Choose the bootloader by using the Volume Up key

f.	Press Volume down to activate

g.	Connect your PC to the phone

h.	Start CMD on the PC and browse to the directory where ADB is installed (e.g. C:\adb)

i.	Type: fastboot oem unlock

j.	You need to confirm by using the Volume Up key. YOUR USERDATA WILL BE ERASED

5)	Flash the customized TWRP recovery image for the Elephone P8 3D. I made this rom using Carlivs image kitchen, using TWRP 3.0.3 for OPPO FS1. Unfortunately, this did TWRP worked fine if you booted it with: fastboot boot recovery.img, but when I flashed it, Touch did not work. Luckily, somebody found out what the problem is and he wrote a complicated, but complete story how to fix it and it works now!! See github.com minimal-manifest-twrp READ_ME_FIRST issues thanks to user “LosTigeros” for his post. The TWRP image can be found at Custom TWRP

Type: fastboot flash recovery twrp-P8-3d(patched).img

6)	Test TWRP by switching off your phone and the reboot into recovery (press volume up and on at the same time and choose “recovery”. Do NOT choose the option to install the TWRP app!! While you are at it, use backup to backup all the partitions.

C- Rooting the phone

7)	From TWRP, install the magisk man zip file

8)	Test if your phone works and if you have root access

9)	Reboot the phone into the bootloader

D-Lock the bootloader again

10)	Lock the bootloader: fastboot oem lock (your user data will be deleted again)

11)	Switch off your phone and the reboot into recovery (press volume up and on at the same time and choose “recovery”)

12)	Use the option “wipe” in TWRP to wipe Dalvik cache, cache and user data. If you skip this step, your phone will continue to boot into the recovery mode ….

13) You should now restore your user data

14) Your phone should work again now and should be routed….

E-Current developments (June 1st 2018):

- The stock ROM and stock Recovery were extracted by ProfessorKNOX and uploaded to MegaNZ (see post further down)

- There is currently a scatter file available for the P8_3D which seems to be working (see link further down)

- As far as I am aware, so far no newer TWRP files than the TWRP 3.0 I posted have been succesfully tested yet

- Finally, Elephone P8 3D is now supported by the universal Coolpad Toolkit of KP@2016. This Coolpad Toolkit can now be used by any Elephone P8 3D owner to make rooting easier. Please make sure that you know what you do when you use the tool and ALWAYS make backup copies of your full ROM before changing ANYTHING. I have NOT tested this toolkit myself Link to coolpadtoolkit/

Good luck! Paul
