[Upgrading, Modifying and Unlocking] routehero:
For my interest, I captured traffic on my USB bus while doing a flash of the phone with LG Utils.

Snippet is below. Tool is called Bus Hound for anyone who is interested.

This is the 'partitions.mbn' file that's in the DZ firmware package.

Anyway, we can do some alignments and see that there's some significant amount of data that we don't readily see from Linux. Particularly, the AMSS partition, which is Qualcomm's brains for a cellphone.

Interesting stuff. A snippet out of oemsbl.mbn @ offset 0x00035AAC which looks like a password of sorts.
