[LG G Pad 7 Questions & Answers] PRichardson:
Partition Info for LG (v410) Gpad.7 AT&T.LTE

It may be too late to be useful anymore, but in the narrow case that might help speed along a custom ROM (hopefully CM11).

(& I'm also little confused why the v400 is lumped together with the v410 in PaperWastage's OP, but regardless) ...

... below is the partition info from my v410 (AT&T, LTE), along with the actual images:
