LG G2 Unbrick - Help needed

Hello,

I'm currently facing an issue with my black 32 gb T-Mobile variant of the LG G2.

Situation: I previously installed Cyanogenmod 13 (stable/snapsphot) for D801 (Please note: I have confirmed this phone to be a D801 via checking mobo). It will not boot into Download mode or Recovery Mode.
Attempts to boot into recovery mode return "Boot certification error" which I had previously received before this brick occurred... I suspect due to incorrectly flashing TWRP 2.8.6.0. Furthermore, all attempts to enter
Download mode return the dark blue "Download mode" text with the dots then goes into a solid black screen that flashes between screen off and screen partially lit when plugged into the computer via USB.

Computers I have on hand:

- My gaming desktop running Arch Linux 4.7.2-1-ARCH according to the "uname -r" command.
- My Lenovo Thinkpad T60p running Windows 7 Professional 32bit.

Steps I've gone through in attempting to repair it.

- Installed all device drivers (both LG and both Qualcomm 9006 and 9008 drivers).

- Attempted to use BoardDiag 3.99c to flash KDZ/TOT files only to be stopped by a failsafe telling me that my device wasn't detected in Download mode. As I'm unable to enter Download mode, I'm not sure what to do with the BoardDiag tool.

- I've tried SRK tool to no avail... It stated it couldn't find my device. Funny because my device shows up as two instances "qhsusb_bulk", one of them turned into "qualcomm hs-usb qdloader 9006" when I installed the driver, but the other partially works, Windows suggests a "usb mass storage device" for the second instance of "QHSUSB_BULK". I am unable to get the a driver to install for the second instance of "QHSUSB_BULK" to install.

Upon plugging the device into my Linux desktop and following this guide: http://ift.tt/Kx3ner... I am able to see 39 partitions when I issue the command "ls /dev/sd*". I am able to see /dev/sda1, /dev/sda2 which is my SSD, root, and EFI partition for my main OS, /dev/sdb1 is my main 1 TB hard drive I use for storage. I should see /dev/sdc1 thru 39, but Linux only intermittently detects the partitions on the phone. It does however consistently detect the phone when I type lsusb.

I am quite confused as to how to fix this and need further suggestions on what I should do to resolve this. I've been struggling with this for over a week.

Anyways... please help me with this. I'm desperate to get my phone working again.
