Not sure what you mean by "formatted the phone" but if you can still get back to TWRP recovery, you should be able to fix it by using the built in terminal feature there.

To access recovery using the external keys, first hold power for 15 seconds to be sure you're powered off, then release. Then press both power and volume down until it boots to the LG screen. Once you see the LG screen, release the 2 keys, then quickly press and hold them both a second time. You should see a prompt to factory reset the phone. As long as you still have TWRP, you can press power twice and instead of factoring resetting, it'll bring you into TWRP instead.

Then open the terminal option built into TWRP and enter the following line, making VERY sure you get it exactly right including spaces, slashes, everything.

dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota

Should be able to reboot to system at that time.
