So here is a link some of you may find useful.

It is the files needed to dump an image of our bootloader...




EDIT!

HERE is some fun Chinese info. I believe the site wants you to buy this document. I have searched for this document with no success as of yet. If we get the info on Secure Boot 3.0 maybe it will help us crack it.
 
This should be instructions on how to use the files above to dump the phone to usb. Good starting point right? My hope is that someone uses the instructions in this post and files linked above to dump the bootloader to a usb drive. Anyone up for the challenge? I have a spare LG Motion with a cracked screen (great for dev) for whoever successfully dumps the bootloader so we can crack it. I am hoping we can merge Nexus BL with ours to create a sweet ass bootloader / kernel / roms.

arm7 has nothing to do with actual software im afraid. most cpu's since mid 2010 have been arm7 or higher. the best way i can explain it is

arm 6 is like the old amd 2 socket while amd 3 is new arm7 (with arm15 being amd3+) inside amd3 there is a lot of different cpu's most of which require different drivers than the other cpu's.

the whole core concept im getting at is all squares are rectangles but not rectangles are squares.

i made a quick little chart that took far longer than it prolly should have. but you guys are looking for an lg device that would be in that orange box. you get one that means that requirements (pretty slim pickings :/) and gets unlocked and there is a very good chance you guys will ride t hat wave.

as you can see just jamming an arm7 software could have caused some serious issues for whoever may have tried it. obviously this doenst cover everything but hopefully its enough to at least give you guys a clear idea :)

did you see the article links I posted in the other thread for a bootloader? I think there was an evo link there. I wonder if it's the same evo they are talking about. but the chart did help somewhat.

Does it matter? That's a pretty good list of possible tests. Only like 4 lg phones though

Three of which we already knew of - Spectrum II, Escape, and LTE2...



Shabby/PG, these are stupid questions but: how hard would it be to make a bootloader from scratch?

Is there a way to give a false positive on the bootloader/kernel/sbl check? Like early in boot, symlink the real bootloader/kernel/sbl partition on the SD, destroy symlink, c/p unlocked bootloader/kernel to the right partition, and boom? Or fumes?

Is there anyone that could look into this? (Other than Adam Outler)
