Ok now you need to turn the phone off, then turn it back on by pressing volume down + end at the same time and this will bring up the hboot menu. Now press the volume up button and this will bring up the recovery menu. Use the trackball to select "flash zip from SD card." Use the trackball again to select the ROM that you put on your memory card and install it. When it is finished, power down the phone then turn it back on just by pressing the end button. Let your phone sit until the ROM boots up. If it doesn't work just post here again saying exactly what happen and what ROM you are trying to flash.
