Do the same things I mentioned in the other thread you started.
Another option is to install recovery through fastboot. Then flash a rom.

And if you have TWRP already, just flash a rom. Or restore a backup.

Hey brother, had a similar problem myself my first attempt at flashing.
Go to the LG website, click Products at the top and go to mobile and cell phones in the drop down. Then filter by carrier (since LS970 is Sprint), Sprint. Find the Optimus G, click it, click product support, software update, then download the USB drives and install. Restart your computer, plug in your phone while in either download or fastboot mode and get her fixed!
Good luck!

So you were able to tot back to which version?
Your phone is still identified as ls980. If you have zvc, use ioroot25 and auto-rec to get recovery.

Thank you my friend for your respond but I changed my phone...My ls980 I had unbricked it I sold it..Now my phone is lg g2 f320...

I would root and auto-rec, but all the root methods I have found require a recovery mode. Even when plugged into adb, the phone will not force into recovery. Is there a way to root without recovery mode?
Thanks.

Ioroot 25, will do the trick. Airplane mode, USB debugging on. No recovery necessary. Then install auto-rec and run.

I've found the kitkat rooting tool for Optimus G Pro which was released yesterday. It's confirmed to be working for F240x series phones with KitKat.
StartRoot.bat will take you to a cwm recovery mode in where you can select the sideload option to install the root files. Once done, just install supersu from Play.
Just tried it on a F240K and works fine.

It's working On AT&T E980 (unlocked) E98018c too

With the phone turned off, press power & volume up buttons at the same time. Then when the white text message comes up, release both buttons.

i was on zvc, and i tried doing that abootzv7 downgrade and i dont think it worked....thats the only thing i can think of at the moment. i tried doing the downgrade before flashing, and i flashed the twrp recovery by the guy in the same link i posted. i didnt even try adding a new rom yet. I am able to push files to my phone through adb in the recovery mode at least.

oh my goodness...i just used the optimus rom http://forum.xda-developers.com/showthread.php?t=2590234 and its working but the keyboard isnt

Try another keyboard and see if that works. Cloudyfa ported the lg3 keyboard and it is nice.
If you want to be best fixed. Grab Cloudyfa auto-rec and use it. Under android development of g2. This puts recovery but also fixes download mode in case you need it.

And the next second its searching for networks. 4 stripes again and the whole story keeps repeating itself . How do I fix this i tried rebooting and going in and out of airplane mode.

Best would be if you could do a fresh install of your firmware using the flash tool ie. the cse flash. Do you have your firmware file downloaded somewhere? Another option I can think of is repairing using the LG PC suite. You may like to consider these options.
