You can use the srk tool, its the easiest method.

Remember you will choose d801 to fix.

I'm sorry for posting my thing here but I was unable to find where to make a thread from. (And I'm in REAL BIG TROUBLE)

I had rooted my d800 and installed twrp 2.7.0.0. I flashed a ROM (via https://forum.xda-developers.com/att-g2/development/rom-stock-lollipop-30b-stripped-t3144195). My phone booted and worked well until I rebooted it. Now it's stuck on the boot screen (no bootloops though).
The worst part is my phone DOES NOT CONNECT TO A PC EVER SINCE I ROOTED IT and I forgot to flash a custom recovery (and don't know how to access the stock recovery). I do have the backup of d80020y system but don't know how to access recovery.
Do you have any suggestions @iowabowtech.

Okay. Finally. For the first time my phone does connect to the PC. But it shows under driver software installation that
USB Composite Device - ready to use
QHSUSB_BULK - no driver found
USB Mass Storage Device - ready to use
Qualcomm MMC Storage USB Device - reafy to use

It says that QHSUSB_BULK driver isn't installed but it still shows the numerous drives (I don't know what that means). What should I do next? Follow the same guide as for a QHSUSB_BULK error (as on http://androidforums.com/threads/lg-g2-d800-bricked-soft-bricked-back-to-brick.953331/)?

There is a qhusb driver posted in one of the threads here. That would show you the exact error code. But I can tell you already that you are in 9006 mode. So yes, you can use the same advice I just posted to the previous guy. The srk tool from XDA.

Edit: here's the link for the qhusb drivers:
https://www.dropbox.com/s/3hovx8h7nauy7e6/Qcomm_Drivers.zip?dl=0

Instructs for driver install...unzip into a regular folder on your desktop. Go to device manager, right click on qhusb device and manually update driver using the entire folder of drivers on your desktop as the source location. Windows will pull the individual files it needs.

How to do that 'dd'? While in download mode? (As I said it's the first time my phone has connected to the PC, I haven't spent time with adb ever)

How to do the 'dd'? While in download mode? (As I've said before it's the first time my phone has connected to the PC, so I haven't spent any time with adb. I'm a noob)

Your phone was showing up as being in qhsusb_bulk (9006). That's why all the extra partitions were showing up on your PC. So while in that mode, my advice was to use the srk tool from XDA developers site. I linked it several posts ago for another user having the same problem as yourself.

You don't have to know how to use the dd utility when using the srk tool as it does it all for you. You just select your model and choose the option to fix a 9006 bulk brick.

I'll try that ASAP. Thanks alot for your precious time and guidance

EDIT : I just read on a thread that G2 could be unbricked just by kdz/tot if download mode was accessible. Do I still need to dd write those img files if that's the case??

EDIT2 : Is it possible to dd write the TWRP img instead of recovery.img ?? And then flash the system backup of d80020y that I did before bricking. (That'll be easier for me, as well consume less data. Data is life) @iowabowtech
