I was trying to install a new room on my htc desire but it was looping the white htc screen. So i thought, i'll just find another room and install it. But i did a terrible mistake i've formated the SD card to fat 32 and now i can't flash it cause it keeps saying can't mount /dev/block/mmcb!!!!! I belive it is because i've formated the regular android files that were on SD, and, since i can't load the android rom, i can't get them anymore. How can i fix it?
