Pretty sure I flashed mine from OEM firmware, but it's been a while. The nmrpflash utility can be a little picky. And we have no idea what file / version you're trying to flash, but the factory-to-ddwrt file wasn't working for quite some time until things were fixed. Worst case scenario is serial + TFTP. Build 52869 is the first build to actually flash and boot.
