[Q] SGH-T679 Flash Back To Stock via Odin - Not Writing To All Partitions

I am following the wiki instructions to flash an SGH-T679 back to stock firmware using Odin, using the files at the links provided:
http://xdaforums.com/wiki/Samsung_Galaxy_Exhibit_4G

Prior to this, the only thing I did to the phone was to upgrade to AOSP 4.1.2 using stock recovery, which worked fine.

However Odin does not seem to be writing anything to either the system or preload partitions when I do this (and now the phone will no longer boot past the splash screen). I have tried both Odin 4.43 and 4.44.

I did notice that the key combination to enter the bootloader changed after I ran Odin: it went from Volume Up + Home + Power to just Volume Up + Power.

I have not attempted to repartition or format the internal memory at any point. I am wondering if perhaps the Ancora.ops in the post above does not match the partition table on my device? Or is there something else I should try?

Thanks in advance!

Solved: the Ancora.ops file in uvlg3.odin.zip on the Wiki page is missing the preload partition. I added "12,preload" to the bottom of the file (per arco's Ancora.ops file found by Google -- can't link to it because I'm new to the forum).

Did you use uvlg3.flash2.stock.zip for firmware from the Wiki page? Coz I didnt find this file on the Wiki page.

Look just a few lines below that on the page, where it says:

Download Odin (Google it) and the stock factory images: uvlg3.odin.zip
