D802 Won't install stock rom with LG flash tool 2014! (No Recovery Mode & Bootloop!)

Hello,

I have a D802 LG G2 Android phone, and I've been flashing roms for almost a year now, I knew my way around LG Flash Tool 2014 until I lost my backup files on my USB. It didn't really matter much because I could find the right version for the flash tool from the imei of the device.

The last 2 rom's I've had were CM 14.1 (unofficial), and I had edited boot.prop to get google assistant using an app from play store.

I was quite fine with the rom until I had learned that CM was officially shut down and that they had moved into Lineage OS, where I decided to install Lineage OS. Everything went pretty fine, I fully wiped my phone, and and flashed Lineage OS for D802 which I downloaded from the official website, I also downloaded the gapps and flashed them, and everything booted up perfectly. Last thing I needed was root access, and there was the download page on the Lineage OS website as well. I flashed everything and went in to the SU app, and it prompted that it had SU binary update, I accepted and the phone went into recovery to flash the updated binary. After that I got stuck in a bootloop.

I tried to go back to recovery but no success. The only way I could repair this was LG flash tool 2014 and then go back to stock and re-install Lineage without the binary update. But LG flash tool will go up to 2% or 4% and then says phone disconnected...

Here is the log from the flash:
