I didn't boot before doing this the first time and had no issues. Now, I'm trying to upgrade to 5.7.894 before reflashing Mav so I get the updated baseband and kernel, but it keeps hitting errors.
EDIT: Well, I gave up on stock flashing 5.7.894. I flashed Mav, it booted fine, I flashed DJMOD's theme, no status bar...? I've tried flashing 2.5 with Bootstrap, booting, rebooting, flashing DJMOD, done the same in SS, tried flashing 2.5, flashing DJMOD, then booting...no luck. I'm torn now. Go back to my no texting Nand and trouble shoot more, go with stock 2.5, or go back to Liberty (shotty camera). Sorry for being a huge pain in the ass. Thanks for the great dev support man!
Ok, I'm convinced it's just my device. Flashing just 2.5 results in no status bar. Looks like I get to have what remnants of my sanity I still possess bludgeoned from me by Big Red's customer service tomorrow. If I can't talk them into a GNex, I'll be sure to root, protect, and flash 5.7.894 immediately and come right back here with a clean device.
