[Q] AT&T's 6-11-14 FOTA crashed my rooted D800

I need help to restore my phone to functioning. It only boots into TWRP.

Before the ATT FOTA, the phone was running stock OTA KitKat 4.4.2 with latest kernel. It was rooted with ioroot 2.5. I also installed TWRP 2.7.0 to evaluate custom ROMs. I had done a nandroid a month back, but I can't recover it in TWRP as it's not listed. TWRP indicates I may have lost root access and tries to reinstall SU to no avail. I did a wipe of everything but data, so there is no SU to run.

I've got my computer setup with ADB 1.0.32, but I'm not able to get the LG unified USB driver to work. This has halted me as I hoped to push a ROM onto the phone.

Please help!

I followed the thread and I used the TWRP command line to run:

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


Below is the output:

Updating partition details…
Full SELinux support is present.
/ # dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota
dd: writing ‘/dev/block/platform/msm_sdcc.1/by-name/fota’: No space left on device

The phone is still stuck in a boot loop and loading TWRP. Any recommendations?
