[Android Q&A, Help & Troubleshooting] Creater0822:
The problem that I've put into quotation below has been solved and here's what happened: I've basically been an idiot.

After I had gotten TWRP ported I did a reboot from TWRP into the system. But little did I knew that when I swiped for the reboot into the system, I had accepted to let the TWRP flash a SuperSU that wasn't compatible with the phone (some SuperSU were for whatever phone my TWRP originally intended to be for), hence breaking it.

Either way, you came here for the TWRP image that's working for your VKWorld VK6735X so you can find that, as well as the flashing tool I used from my Google Drive folder.

But before all of that I obviously have to tell the same boring warning: I'm not responsible if you lose your data or brick your phone! Make sure to have backup for whatever you don't want to lose!

Head to the Google Drive folder, download the two zip files to your pc (lol not your phone), extract them anywhere you like and follow the steps below:

From the extraction of "Flash VK6735X.zip", install the drivers from the "Driver" folder. Windows might be acting stupid because it's Windows.

After installing the drivers, run "flash_tool.exe" which is located in the folder called "SP Flash Tool v5.1708"

(Optional) Go to your phone settings, go to "About phone" and tap the "Build Number" until you've unlocked the Developer options.

(Optional) Then go to the Developer options and enable "OEM unlocking" as well as "USB debugging", honestly you don't have to but why not...

Power off your phone and take out the battery

Back to the flashing tool you've opened in step 2: Load a so-called "Scatter-loading File" and select the file "MT6735M_Android_scatter.txt" which you've extracted from the "TWRP port for VK6735X.zip" file. The "recovery.img" file must be located in the same directory so do not separate those!!

Leave your phone battery removed and do not connect your phone to your pc yet: Press the download button

After pressing the download button you can connect your battery'less phone to your pc, no need to hurry since the flashing tool will only start once your phone's connected.

Wait 'till the flashing tool pops up a small green window saying it's done.

At this point you can place the battery back into your phone and unplug it from your pc.

Congratulations, you've installed TWRP.

Step 6:

And this is step 7:

How to get into TWRP:

Hold down the volume up button, then press and hold down the power button whilst still holding the volume+ button and wait.

In a few seconds you'll see three tiny options on your screen, with the volume up button you'll select between the three options and with volume down button you'll enter them.

Choose Recovery.

Be cautious: DO NOT swipe in any situation inside TWRP before you've read what it says, otherwise you may accidentally flash a SuperSU that isn't compatible with your phone and get the exact same problem that I've described in the quotation section of this post xD

Lastly you can find the Stock ROM inside the "Firmware" folder, if you select the scatter file inside this firmware folder with your flashing tool you can basically flash your phone back to stock.
