I also got the 4.3 update, but I made sure to preload the last stock image using oden, "or the one that I found which was 4.0.1", which of course cleaned out everything, and it locked down my phone and un-rooted it, and I was fine with it. I needed to have all my apps to work like they should, and all the roms that I have tried over the years had some issues with certain apps, especially bluetooth never worked the way it should with the roms, well I am happy with the 4.3 stock rom , everything works as it should, phone is smooth, of course I am using nova launcher, the only issue I have encountered is the volume seems a bit on the low side. In regards to the poster, it looks like you have hard bricked your phone, it is all over xda with people loading the latest Verizon update while they where rooted and unlocked. Sorry to be the bearer of bad news. Never take an update over the air while rooted and unlocked. Have you tried safe strap, there are instructions on xda. Can you put the phone into download mode and connect it to Odin, let me know, I can direct you to the link for the stock image.
