Help In such a deep hole help!!

[Jason M]

So I recently bought a Verzion version of the LG G2 from some guy and it was working fine. After I had it activated Verizon was downloading a Software or System update and after it installed, my phone never booted up to the main screen. Turns out the phone was rooted and had flashed ROMs and what not. I don't really know what it exactly means but I'm starting to understand more and more the more I try to fix it. As of now the only thing my phone does is boot up to the Team Win Recovery Project v2.8.1.9. Not knowing what I was doing, I wiped everything from the phone so the only thing on the SD is the TWRP file. When I go to the reboot option > Power Off I get sent into the screen "Swipe to power off" Above the swipe It says no OS installed. Once I swipe I get put into another Swipe screen but this time it's swipe to install. "Your device does not appear to be rooted. Install SuperSU now?" When I swipe to install, the phone's CMD shows for about a second then it reboots. Note* When I go to the factory reset screen(Holding Vol down and power button) The top left of the screen says rooted. Again nothing besides TWRP files are on the SD card.
What I have downloaded:
LG G2 driver
KitKat_Baseband_VS980
ABD and Android Studio with SDK manager
I was searching on all sorts of forums and they're saying CloudyG3_2.1 is a good way to get the phone working again so I have it downloaded as well.
Also just downloaded ioroot
I tried sideloading it but couldn't really understand how it worked. I couldn't get the files into my phone. ROMs don't really matter as of now because I can't even use my phone, I'm really just trying to get my phone to factory settings as if it was never Flashed/Hacked. If i do manage to recieve help and fix my phone I wouldn't mind added the cool stuff but as of now I just want my phone back.
Please Help!!

thats odd.honestly an update should never have even updated your phone on twrp.it should have just failed.find a custom rom zip file put onto an sd card or something,go to twrp and install it.accept the install supersu if it asks again upon reboot ya ya ya.honestly i dont think it was the rom.you saw the update didnt take and you advanced wipe be my guess removing the system and everything.


also uhhhh i dunno why your downloading a whole sdk and adb interface.last i checked i dont think any lg uses those commands

 

[Jason M]

It says a rom is too big. can you link a rom that'll work?

 

[iowabowtech]

Do you still have download mode? If so, you may be best off restoring the phone to factory 26a. To check for download mode, power off the phone entirely then press and hold volume up while at the same time plugging into a PC.

 

[Jason M]

No i cannot go into download mode. I have now installed a ROM to the phone but im still stuck in the TWRP menu. It wont reboot to the actual phone

 

[iowabowtech]

Boot into TWRP. Don't select any menu items. Then use adb to run...

adb shell
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/misc bs=256 count=1 conv=notrunc
