Hex Editing

HEX Editing with XVI32:

Overview:

* First let's take a look at XVI32 and familiarize ourselves with its features.

* Open XVI32 and open the 0032_0001.seem in XVI32 just to take a look.

* On the main screen, you'll see two columns. On the left side is the "HEX" representation of the file. On the right side is the "ASCII" or text representation of the file.

* When one of the columns is shaded, that means it's inactive and you're working with the other side. In the screenshot below, you'll see that I'm working with the "HEX" side.

* Take a look at the status bar at the bottom of the screen. You'll see "Adr. Hex" when you're working with the "HEX" side. This is the hex offset, or the location of where you are in the file. This is very important. I'm at offset 35 right now.

* One last thing, when working with SEEM files, each hex offset has eight bits or "switches" which can control up to eight different settings on your phone. When we adjust one of these settings we have to change the proper bit. XVI32 has a nice tool called "Bit Manipulation" under the tools menu. Go ahead and select it. You'll see that for the offset that I'm looking at, bits 7, 6, 5, and 3 are checked or set to "1". Bits 4, 2, 1, and 0 are unchecked or set to "0". When adjusting settings in the SEEM files, you'll be referred to an offset and a bit within that offset to adjust. Use the bit manipulator to do this and only change the bit that is referenced. Remember, checking the box sets that bit to 1 and unchecking the box sets it to 0. Be sure to click "Set" after you check or uncheck to actually make the changes in the file.
