    I need some help for the resident gurus' here.

    I would like to flash the modem that came with my last firmware update, but I can't find a download for that modem anywhere. How can I do this myself? I have the MD5 file. So I was wondering can I extract the MD5 file (using 7Zip) until I see the modem (it says its a .bin format), and then just archive it as a .zip? Will that make it a safe CWM flashable file, or am I completely off base here?

    Thanks for the help

    The easiest way is to take an existing cwm flashable modem open it up and delete the modem.bin. Then add the modem.bin from your firmware to the cwm zip.

    Wot he said. :)

    Best to use 7zip on your pc to edit the zip file.

    Ok, so I took a LPS kernel that is CWM flashable, used 7Zip to find it. I double clicked to open the kernel and it showed me a META-INF file, a flash_image file, and a modem.bin file. I deleted the modem.bin file, but how do I add the one that I want?

    Also are the other two files gerneric then? Nothing on them needs to be changed?

    With the 7zip window opened just drop the new modem file into it, close, then you are done.
    No nothing needs to be changed in the other files/folders unless the zip file was originally made to work with a specific rom only (Most modem flashable zips won't be so you should be ok).

    I must not be understanding something quite right. While in 7Zip I can see the kernel, now without a modem in it, and the modem I want to add. Still in 7zip, it won't let me drag and drop the modem into the kernel from inside 7Zip.

    Is the drag and drop part done in the regular folder not in 7Zip or is there something I'm missing?

    Just right click the zip file and goto 7zip then open archive.
    From there on in its just windows features ie double click to go into folders, right click delete etc, and once in the correct folder just drag modem.bin file from pc into the zip.
