<6>[ 1.167571 / 01-01 00:00:01.159][3] [120] set_dload_mode: download_mode:0

This verifies the order that parts of the firmware are loaded in. It also invalidates that I thought they weren't loaded when in download mode. I can now verify download mode will still load even if they fail verification.

This also validates that booting from SD card is no longer possible:

<6>[ 1.165940 / 01-01 00:00:01.159][3] B - 525240 - bootLUN:1, currentLUN:1
<6>[ 1.165978 / 01-01 00:00:01.159][3] B - 525240 - xbl is matched with bootLUN
<6>[ 1.166028 / 01-01 00:00:01.159][3] D - 976 - LGE SBL Image Loaded, Delta - (51579 Bytes)

bootLUN is pulled from QFPROM, so they COULD have had SD card support, because ...... notice that SBL is a delta of XBL.

EDIT: my understanding of this was backwards. I now not only think it is possible to boot from SD card, but with a little more work, I am sure I can get it.
