Flashing from SD card..bootloader mode?

[evilvoice]

Well, I dont know what the qualifications are...I know I tried without formatting the card because windows said it was fat32 when plugged into the phone and it did not work. I then reformatted as FAT32 with 512 Table on a 2gb card and it worked...I didnt flash, but the option came up finally...it wasnt a clean card either because I wanted to test to see if it overwrote the card, which I dont think it will...so these are my settings

2GB FAT32 512 bytes
