Just an update on my very slow attempt to bring my D3 back to life. I've been running on a backup phone for a week now and it's better but not great. I did a factory reset on my primary phone but found that even this didn't correct my non-functional camcorder. I took it one step further and SBF'd the phone back to original stock (wiping everything in the process). This has fixed the camcorder problem and I am now in the process of loading my apps back on and reloading all my music etc. I'll post the final result of this experiment in the next few days when I finish reloading everything.
