Hi,
I finally made the complete process of rooting my phone few minutes ago after struggling a bit. I wanna thank everyone here who were cooperative to share their experience.

Few notes from getting my hand dirty:
1- the batch file is written in Chinese, so you have to open the file with notepad and modify it yourself. Also path of commands were problem to me so I made my mind to make "static path to adb and fastboot executable:

@echo off
echo.
echo Check devices*
echo.
E:\TWRP\tools\adb devices
echo.
echo Remove old TWRP
echo.
E:\TWRP\tools\adb shell rm -r /sdcard/TWRP/theme
echo.
echo Reboot to Bootloader
echo.
E:\TWRP\tools\adb reboot bootloader
echo.
echo Install* Recovery
echo.
E:\TWRP\tools\fastboot -i 0x17ef flash recovery E:\TWRP\img\twrp.img
echo.
echo Install TWRP:
echo 1. Press and hold the volume up button on the unit
echo 2. Press the Enter key on the keyboard of your PC
echo 3. after the appearance logitipa TWRP release the volume
pause > NUL
echo.
echo echo in TWRP!
echo.
E:\TWRP\tools\fastboot reboot
echo.
echo To exit from the command line , press any button .
pause > NUL

2. You may be unable to flash the image due to that bootloader is locked. Follow these steps:
--- Go to tools folder. right click in any blank position while pressing SHIFT key and select "open command window here"
--- write the following commands to unlock it:

adb reboot bootloader
fastboot oem unlock

-- if you see "OKAY", it means your bootloader is successfully unlocked.

fastboot reboot

After that, run the batch again.

Note: The steps mentioned will ONLY INSTALL TWRP. You have to reboot again to install SuperSU.zip to root your device. In other words, you will flash Lenovo_PB1-770M_TWRP-2.8.7.7_by_SevenMaxs.zip as in the first post of this thread, then you have to reboot your phone while keep volume up to enter TWRP mode and install SuperSU

Is TWRP installed on your device?

I followed all the steps mentioned in the post. When I press enter after running the .bat file and the device reboots, I choose update firmware from sd, it shows sd card not mounted.

Did maxseven Russian splash screen loads when you press volume up button while powering up your phone?

I didn't see the splash screen. Perhaps it was too fast?

U can try this :

1. Set up ADB and Fastboot on your computer. You can download the full Android SDK from here, or get the quick ADB and fastboot installer from here. For Mac or Linux OS, click here.

2. Install USB Drivers on your computer.

Installation Instructions

Make sure you have setup ADB and fastboot on your PC. Also accept Always allow from this computer when you plug in the device for first time to enable USB Debugging.

Now connect your device to PC and accept the RSA Authentication prompt. Now open a command prompt or terminal window. Do this by holding shift key on your keyboard and right-click on an empty space and select “Open command window here” option to launch a command prompt window. Verify connectivity issuing the following command in cmd:
adb devices

Boot into the bootloader or fastboot mode. To do so, you can also issue the following code, while connected to the PC.
adb reboot bootloader

Now, as the Phab Plus isn’t recognized as a fastboot device, you will have to specify the OEM id. It is 0x2b4c meaning, any fastboot command must be suffixed with the following code.
-i 0x2b4c

Now this is important. We will proceed to unlock the bootloader. To do this, issue the following command. Choose yes on the device screen if prompted.
fastboot -i 0x2b4c oem get-device-info

If you see a message like (bootloader) Device unlocked: true, then reboot to bootloader
Bootloader on your device should now be unlocked. Reboot your device normally or issue the following command”

And start open the .bat file again :fingers-crossed:

I tried to follow the steps on my Lenovo Phab Plus but once it goes into the bootloader it doesn't accept the "fastboot -i 0x2b4c oem get-device-info". It just keeps on stating "waiting for device". I don't know what to do anymore.
