In this kind of scenario the best way to unroot or bring back your device is to Install Stock ROM On Lenovo K3 Note ROW Version.
Yes! Installing the stock ROM or Official ROM can bring your device back to the factory condition. Same as when you first access your Lenovo K3 Note ROW version.
A. Download Tools:

Both are suitable for k-50
Download flash_tool And rom contain all in in one link of A40 and T5

B. File Preparation

Unzip or UnRar all the above file you downloaded.

C. Enable USB Debugging

Go to Settings>> About>> Build number and tap it 7 times to unlock Developer options. Then return to Settings>> Developer options and tick the USB Debugging option.

D. Install Driver

Install the driver then restart your PC, then connect your phone to PC via USB cable and wait till Windows configures it. Make sure the USB Debugging is enabled in this process. Once the configuration has completed, again restart your PC.

1. Charge your phone up to 80% and disable all those firewalls or antivirus on your PC
2. Run as Administrator the flash_tool.exe, that you will find by extracting flash_tool
3. Click on “Scatter-loading” and browse the scatter file MT6752_Android_scatter.txt, you will find this in target_bin folder inside the K50a40_S112_150610_ROW folder.
And t5 choose the folder vibe
4. In the menu “Option” tab, go to “Download”, and put a “tick” in the “DA DL All with Checksum”;
5. Now choose the Firmware Upgrade option like this
Now hit the Green Download button like this pic
6. Now turn off the phone and remove the battery for at least 5 seconds, then put the battery back.
7. Connect your Phone to PC via USB, this will start the flashing process.
8. Once the process has completed, we will see a huge green check box. Now we can disconnect the phone from the cable.
9. Now switch on your phone, it will take some minutes for first boot.
If the flashing process does not start just remove the battery then put it back and repeat the process or install the driver properly. Do comment for any doubt or question.

    @Vikas .These roms are already available in the catelog. Sharing both these old roms on the same page with the same instructions would cause new users to loose their NVRAM information trying to flash K50-t5 a K50A40 build. It would cause WIFI issues on their devices. K50a40_S112_150610_ROW is one of the worst unstable K3 note roms available. I suggest you to obtain K50A40 ROW marshmellow latest official rom availabe here.
    Good luck!

    Understand flashing the K40 row rom but the K50-T5 will not work unless you flash it with stock/custom recovery on phone itself

    Saying this coz the downlink for KT50 downloaded me "Lenovo_K3_Note_VIBEUI_V2.8_1534_7.201.1_DEV_K50-T5_WC13_(by_xdafirmware.com)"

    No vibe folder with a flashable "flashtool" rom after unzipping.

    This only contains an update.zip, ment to be flashing with stock recovery or with custom recovery (with update-script mod) on phone.

    Is the download link for K50 wrong or am I missing here something.

    Be carefull not to use format all/download with flashtool otherwise you loose your nvram (wifi/bt and imei) and serial number, so make backup of your phone so that you can recover stuff if needed.
