No Recovery, Fastboot Won't Work, Bootloop </3

Phone: LG G2 (D801 - T-Mobile)
Windows 7 Home Premium 64-bit

Accidentally flashed non-working recovery img. Tried 1000s of xda pages to fix this. PLEASE help I DO NOT wanna have to factory reset.
[x] adb universal drivers installed
[x] sdk installed, google usb drivers installed
[x] computer recognized phone as adb
[x] sdk-tools folder in C: directory, ran command prompts from this folder (contains both fastboot.exe and adb.exe)

When I try to fastboot my recovery.img file it says the cursed ''waiting for device'
I am trying to recover TWRP back onto my device.

I've been working on this for 11+ hours now please help.

And also my phone is rooted of course.
