You have probably figured this out by now but the bootloader cannot be flashed via DFU and must be flashed via YModem or OTA for Photon and P1 with particle flash --serial bootloader.bin and only after you flash system parts.

Yes, I am successfully updating the bootloader using

echo f > $p1
sb -vv bootloader-0.7.0-p1.bin < $p1 > $p1

where $p1 is the name of the P1 serial device, usually /dev/ttyACA0 or /dev/ttyACA1
