Thanks for this method.Quick update on this, I decided to try the MSMTool Readback process and it worked perfectly fine!
Phone now rooted.
Whats curious is the ddr type prop doesnt exist on my phone. I have model KB2005, am wondering if all of that model is DDR4X or something and thus maybe why its not listed.. /shrug
How do you revert the boot partition to stock before starting the OTA? If you don't do that then an incremental OTA will fail.
