[SOLVED]stuck on black screen - G2 Q&A, Help & Troubleshooting

Hi,
I'm wondering if you could help me out. I bought a D800 G2 today from the internet. I rooted it and then used autorec to install twrp. I then created a backup and selected reboot to system. It then rebooted to a black screen and Now it will not boot. It just gets stuck on a black screen after the lg logo.
adb is working and I can get into twrp using adb commands. I can also get into download mode....
Thing is I have never had an LG phone before so I do not know how to get it to boot again. I read about two methods- KDZ and TOT but not sure which one I should use.
Thanks for any help
edit--tHANKS @thedoctor13th for the guidance...
Solution was to download custom rom onto a flash drive and use my otg to flash custom rom considering I was able to get into recovery. then update recovery and make a nandroid. phone's working to my knowledge. Haven't inserted a SIM into it yet. Will try that tomorrow.

Just try to flash another recovery and its should be ok then.
You can't do anything but use the attached file. Run this its the :G Mobile support tool. Then run recovery and it will download your firmware and flash it again. It will get you out of the softbrick if all else has failed.

Stuck at boot logo, computer has access to file system

I'm in a very peculiar position here, where my LG G2 is stuck as the LG boot logo, but when plugged into my computer I have access to the internal storage. Here's how I got to this situation:
I previously owned a G2 on CM11 that had hardware issues. Before swapping it out due to those issues, I had made a backup using the package listed here, which created a few .img files, including boot.img.
On my new phone, I rooted, installed TWRP, made a backup of stock
Flashed Mahdi Rom
After flashing Mahdi Rom, my phone would immediately boot into fastboot, showing "fastboot started (new line) udc_start"
I did with the procedure listed here to be able to access download mode, and this was successful.
I then followed the procedure here to return to stock, but I got an error in LG FlashTools saying that I had the wrong model number. After a bit of digging around, it seems that this error may have been caused by the Mahdi Rom flash renaming my phone to "G2" instead of "d800".
After troubleshooting this for hours, I took a stab at flashing the boot.img file mentioned earlier through fastboot. Flashing this boot.img is what triggered the predicament I'm in now - I can access the phone's internal storage on my computer via USB, but it's stuck at the LG logo.
At this time, my phone will not ADB, fastboot, or enter recovery; I can only access download mode. When trying to enter recovery, it loads for about 1 second and then I'm kicked out and it goes back to the LG load screen.
Thank you in advance for any and all help

You can't take an OTA w/ a third party recovery like TWRP or PhilZ CWM Touch installed. If you can't flash the *.kdz or *.tot file from download mode, then you'll need to revert to this method...
[FIX] NO Recovery mode, No download mode, after OTA on rooted LG G2
http://forum.xda-developers.com/showthread.php?t=2582142
If you can get into recovery, then you can just flash another ROM or restore a nandroid. If you don't have a ROM on the internal SD, then you can use ADB to push a ROM to the SD while in recovery.
i can enter TWRP, and i can enter factory reset. then what should i do?i dont have a rom in my internal storage
i can enter download mode and i can enter TWRP. but i dont understand... sorryy im totally newbie.
thanks for your help btw

All you need to do is SEARCH and you will find what you have to do in order to get the phone to boot up again.

[Q] Phone working fine but no Download/Recovery

Hello guy's,
i have quiet a strange issues with my lg g2
I was on Cloudy flex (Kitkat) with my rooted G2 and wanted to try out the new Lollipop Cloudy ROM.
So i flashed it using TWRP.
It did not work and i Realized that i should have bin on Android 5.0 stock before flashing.
So i went back to 4.4.2 Stock ROM using the LG flash Tool and a kdz file.
Now the Phone is working fine, but there is no way to got to Download or Recovery mode anymore.
I did not expect TWRP to be installed anymore but i don't even have the stock Recovery and much more important no download mode.
Can somebody help me?

d802
i think i bricked it now!
i was able to root the device and i installed Flashify.
Than i flashed laf.img with flashify according to that FIX: http://forum.xda-developers.com/showthread.php?t=2706590
Now i cant do anything regardless of what i do the LG logo comes up and stays there for ever.
Even when i plug in the USB cable only the LG Logo pops up.
At least i can still see it in device manager but i can not find it in CMD using that instruction:

Well you are doing stuff on your own m8.
You will get a secure brick this way.
More info needed..what is your device recognized as ?

LS980 black screen (bricked?) unsure how to get back.

So I was relatively ok playing with my lg g2, rooted and have twrp 2.8.6.1 installed. It has been couple of months since I can't connect to freedompop/sprint network -- I can't change the cdma setting from nv to ruim/sim, I am thinking that it was the cause. Then I decided to upgrade twrp to 3.0.2, I boot into twrp, flash img, recovery, then I can't boot back to recovery. Something with fastboot. Surprisingly, I still can boot to system. Check root access, still have it. Then I used flashify to flash twrp back to 2.8.7 but to no avail, still the same thing, no recovery but boot into the system. Then I use autorec for ls980 on androidfilehost by bender_07, that's when things went down. Screen just black, not even lg flash screen, nor download mode, nor recovery. When I plugged the phone to computer, it asks to format multiple drives (15 or so), I am not sure where to go now. Anyone have any ideas?
-Found a solution, managed to get download mode working and tot-ing back
