How to receive Right Root in this new Device S3PRO From UMIDIGI Brand

Italian Thread here...

This Thread is not for beginners and all the steps made will be down the warrancy at own risk.

This tutorial will guide you through the process of installing a custom recovery image

on your MediaTek based UMIDIGI smartphone and to receive right root access.


Some possible issues that might need your attention:

• Custom recovery images of different Android versions are not always interchangeable. For example, you can't install an Android 5.0 recovery on a 4.4 system and so on. Any exceptions are mentioned in the list of recovery images.
• At most of the devices, after flashing the TWRP image, first you have to boot into recovery (TWRP) or the stock recovery will be restored.
• At some devices, after flashing TWRP, first you have to root your phone (install SuperSU or Magisk) or it won't be able to boot into the system.
• Once you've rooted your device, you won't be able to install OTA updates anymore but the only way to update your phone is flashing with SP Flash Tool. Flashing a stock ROM (with the stock recovery) will make you able to install OTA updates again.
• At some devices (or specific ROM versions), when powering on your phone to boot into TWRP (power + vol-up), after about 3 seconds, you have to release the power button (even if your screen is still black) and keep only the vol-up button pressed until the TWRP welcome screen pops up or the recovery will be skipped and your phone will boot into the system.
  

What you need:

Driver for Preloader USB VCOM mode:

Windows 10 already can automatically install it or you can use this:

MTK_Driver_Auto_Installer_SP_Drivers_20160804.exe

SP Flash Tool application:
SP_Flash_Tool_v5.1812.rar

Adb Command for Windows pc:

Command adb for dos/windows

A custom recovery image that fits your phone

Procedure to how to flash the Recovery into Umidigi S3 Pro

Now is not possible to flash the recovery throught flashtool because there is a bootloader locked so we must go ahead with adb command.

1) download all the previous files;

2) in Android S3 Pro in "Settings System details" enter in about phone ot make visible the developer options click several times on about phone ....

3) in Setting System will be now shown the developer menu' enter and switch to visible OEM unlocking allow the bootloader to be unlocked.

4) reboot the phone and with power menu' and volume + in the same time enter in booting menu'.......select fastboot mode.

5) Now in windws  pc run the commad cmd or open a ms-dos window and enter in the adb folder ;

6)write the command fastboot devices...and the phone connected with the usb cable must answer the command that is connected..

7) use the command

fastboot oem unlock

o

Fasboot flashing unlock

and wait checking the device screen....

8) copy with windows command the recovery twrp.img in the adb folder and renamed it with recovery.img

to flash in the phone use this command : Fastboot flash flash recovery recovery.img

the process will start ...and wait it...

9) make this command to reboot into recovery mode: fastboot reboot.

10) now take the buttons pushed with power menu' + volume + and select recovery mode....

11) in recovery mode will show probably russian language...skip the alert with the arrow back and enter in details menu' on the right top to change the language...

How to Root your Umidigi S3 Pro

How to Root:
Enter in the Recovery mode.....
You need to FORMAT the partition given TWICE a simple deletion is not enough it seems in Android 7 and upper.
Follow this procedure in this exact order and should solve most problems.

1. Install TWRP through flashtool or adb command  and then directly restore in recovery (twrp) do not enter in android system under penalty of twrp deletion and restoration of the original recovery.
2. Select Wipe / Advanced / select date Yes to confirm. When finished, choose Restart, then always in recovery.
3. Choose Wipe Advanced Format DATA again type Yes to confirm When it ends choose Restart always in recovery.
4. Select Wipe and select cache and Dalvik scroll to confirm When it finishes choose Restart and always in Recovery.

5. Now install Magisk 17.1 use this version tested

Magisk 17.1 (Tested)

you can restart in the android system and you will find magisk installed.

For a full root you have to install from the play store busybox app and install the busybox binaries at least in sbin and bin (system folders) the app will guide you
Busybox see here:

Busybox in the google playstore
I prefer this app to others because of its track automation that doesn't require much experience.

Hi friend :
I found you here trying to find twrp for the s3 pro. We already talked about xda. I have a question. Would this twrp allow a backup of the vendor?
If we had a vendor backup, could we install a GSI?
Thanks for everything

Hi Totmakina,

Yes this twrp is builded to make a backup also of the vendor partition and its data.

Excellent Ghost! You already have your s3 pro? I'm going to buy it right now from my basket! To be able to enjoy it!
With this twrp and having a backup of vendor we can install gsi's and sgsi's (roms covers of other devices?) I do not know if you know the channels in telegram, I guess that of course!
We must be in contact to share.
Thank you very much again for your splendid help Ghost!
