Hey ya'll - I'm having issues booting Android on my Sprint Touch Pro. Any help you can offer would be appreciated!

Here are details:
Hi, I have a Sprint Touch Pro (RAPH800)
I have the Sprint Raphael Radio V1.11.00F
I also have MightyRom 4.12 installed
I have loaded the Android files onto my 4GB micro-SHDC card via ActiveSync.
My problem is that Android won't boot! It gives me errors including:
mmc1: command timeout
mounting /dev/mmcblk0p1 on /mmc failed: No such device or address
mounting /mmc/tmp/system.e2img on /system failed: No such file or directory
etc.
I have reformatted my micro-SD card to FAT32 and also tried msmsdcc_id of 1, 2, and 3.
