Please read the post carefully before typing in any stupid commands that can screw up your phone.

Follow instructions EXACTLY as mentioned in this post.

The reason you are getting a “security downgrade” error is because you are trying to downgrade your bootloader, or GPT partitions. You cannot do that on the device.

Didn't you make backup...? First thing one should do is it....
You cannot flash official zip either soak or final by TWRP, you need stock recoveryfor that...

Now you can only do is flash stock via fastboot method (but you updated to soak it is not preferable)
Try this:
download any custom ROM from development, and load it to memory card, and flash it....

Since you haven't made backup, you have to go with fastboot flashing... As you updated soak your bootloader is now updated with it, don't downgrade it.... You will see gpt and downgrade errors while flashing... I can't say anything more about it, i didn't try that.....

You can follow guides available, see in guide section...
