I downgraded my bootloader to 1.2 to flash to Radio 3.42.50 through an RUU. I then pulled out my battery and stuck it back in then let my custom ROM boot up and quickly get it connected to ActiveSync/Windows Mobile Device Center to use Olipro 2.4 and let do it's thing. You have to do it quick because a newer ROM with an old bootloader will keep restarting after a period of time, so don't dilly dally, connect quick and get to working.
Better yet, just always buy a cheap SD card to avoid usinf RUU's and bootloader
