I deny that: I just successfully booted SHR with: Code: sudo modprobe -r cdc_phonet ; ./flasher-3.5 -k zImage -l --boot='root=/dev/mmcblk0p5 rootwait rw console=ttyO2,115200n8 console=tty0 omapfb.vram=0:2M,1:2M,2:2M mtdoops.mtddev=2 panic=10' with U-boot installed where it was. I can't imagine anything you can try except getting battery and USB away for a couple of sec.
