[Q] Hardbricked D800, Please Help topic

Just got my D800 in and was wanting to put a custom ROM on it. So I started off by rooting it with Stump Root.

I then wanted to put a custom recovery and rom manger didnt work and so I tried TWRP Manager. I selected the wrong phone, the LG G2X and it rebooted and will not come on now.

When I go to device manager, the phone is showing up as QHSUSB_BULK and when I plug the phone into the pc, a list of drives show up and windows wants me to format them.

I am wondering if anyone has the 20y files I would need to fix a hardbricked phone that doesnt have adb, fastboot or download. I believe I would need the following:
1- sbl1.img
2- aboot.img
3- rpm.img
4- tz.img

can I install an earlier firmware version or does it need to be the same exact one that was on it before?

I am talking about using this method:
