Request Help Rooting LG-LS770 (Sprint)

[gjdunga]

So, I've been messing around with lglaf for a while, but I have never been able to get the job done.

I can get the device to respond to listing partitions, dumping the device, but I have yet to figure out how to push something to the /system/bin directory. I'm afraid to do much more than this due to LAF... The only reason I want to root this piece of crap is that it's the only thing I have, I'm disabled and broke, and I keep hitting the internal filespace wall. It sets the sd card as an internal partition and the external card as another, weird name.

Does anyone want to hand-hold me a touch? I know it's probably a lost cause, but I'd like to try... Hell if it goes well, I'd consider putting TWRP on it.

FYI: The device is supposed to be un-locked, I have the MSL code and I've used CDMA TOOL and can access it this way. I haven't tried the Qualcomm QPST.

I am happy to post/provide the full dump of the device upon request.
I have contacted LG directly, and even though they have open source software for the device, the refuse to help to "unlock" the device, even though I own the dammn thing.
