I think it would be possible. I said over a year ago if someone was smart enough to make a "distributed computing/grid w/gpu acceleration" hashcat style attack we would have already cracked the bootloader! I am not smart enough, or I would have already done so. I am sure someone could examine LGs source or even kernel code and hack something together. Perhaps use dragonzkillers kernel "bypass" to allow it to run kernel unsigned. I think it was the LG Optimus 2(P990? So many similiar models). Same phone/spec practically. The GSM is, but the CDMA is NVIDIA Tegra 250 T20 (Harmony) based.

I cant find the link to the repo, but anyone who does develop should be able to find it.----------------EDIT-----------------------------
