Okay, I learned a bunch by reproducing a working stock kernel from LG's sources (in order to avoid problems with GameTheory's illegal terms).
1. The loki_tool from git doesn't recognize the T-Mobile aboot (dated Nov 4th? 2013)
2. The T-Mobile device works just fine with the MetroPCS aboot (dated Jun/July? 2013)
3. /sbin/wallpaper in the recovery put me in the dark for 4 hours with 'Security Errors'
4. The camera works best with the stock (from source, config extracted from T-Mobile config.gz)
I don't mean to keep spamming, I'm just putting 'documentation' for the record.

I tried random ones from other phones on the same line of chips (msm8960, msm8974, etc.) and they either had symbol problems, or other dependency issues...
