Clone a Modem? ( May have bricked SB5100)

[Sunaj]

Isn't the firmware file supposed to be 2 megs? I have a folder with many firmware in it, most of them are 700 kb. Whenever I choose 'write all' assuming this will bring up a box that will let me select a firmware, nothing happens and at the bottom it says " choosing binary or something"

when i try to read all', it gets stuck at 100 percent and never completely finishes
