Hello phone gurus- sorry for my noobiness!

So- I HAD my phone working great- rooted- hotspot (I'm still on unlimited plan)
ACCIDENTALLY installed the OTA (after many weeks of ignoring it)

Then my phone wouldn't boot BUT I could get into TWRP
I tried using the console as posted in another thread (sorry can't post the link- I'm too new!)
but I entered this at the TWRP console:
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota
then hit enter
type
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/misc

At this point I received a message that I didn't have enough disk space after typing the commands as shown.

Then I rebooted and my TWRP is gone...

Now I'm stuck at the LG logo, with no TWRP. Hold vol up, vol down, rebooted many times nothing seems to work, just the LG logo.

I have ADB on my win machine and it was recognizing the phone, but now it doesn't.
In device manager I show three devices when I boot phone with USB attached:
CDC ECM- No driver
CDC SERIAL- recognized as modem
LGE ANDROID PHONE- No driver


Its been at the LG logo for about 30 minutes now.
Help Please!:crying:
