Ricardo's Comment : LG Optimus G Pro (GSM/LTE)
So... after asking around a bit, it looks like all the GSM variants of the G Pro carry the same hardware, except for modem firmware and antennas (which we never change, and neither should you ). This means the CM builds currently labeled as e986 should fully work on any e98x variant, without changes. The one possible exception is E985 (the China Mobile carrier variant).
So... in previous occasions where this happened, we labeled these multi-variant builds for the base model (the one ending in "0"), and we'll do the same again. Sometime soon the e986 builds will become e980.
