New member, first post. I've been using a Nexus 4 quite happily for the last 4 months or so without issue. I received the OTA 4.3 update today and installed it. Upon reboot, I got an error (no details, just a dead droid image that said "Error" beneath it). I let it be for a while, but it didn't boot or restart, so I restarted it manually. I'm now unable to boot the phone; it sits endlessly on the animated X (I've let it run for hours with no change). My Nexus 4 was stock, but I downloaded the WugFresh tools in an attempt to fix things and unlocked it. I tried booting from recovery, the Back to Stock option with Soft-brick/Bootloop selected, ADB Sideload, etc. Sideload seems to work with the latest 4.3 image, but it still sticks at the X upon reboot. I tried the stock 4.2.2 image, but it throws an error because the radio baseband is apparently different in 4.3 and that made its way into my current firmware. I thought about reverting that back to an earlier image from 4.2.2, but I can't find one. Can anybody help me out? This is my only phone and I'm stuck.
