ok, by looking at this, i guess the docs are indeed wrong...(page 6)

You cannot mess up anything, the preenfm2/3 cannot be bricked.

The error in the doc is the symbol x in the address. It should have been a regular X and it was a weird characater. Sorry.
I just fixed the doc. I also removed -R which was useless.
The firmware zip files contained the correct command which are :

Code: [Select]

dfu-util -a0 -d 0×0483:0xdf11 -D p3_boot_1.01.bin -s 0x8000000
dfu-util -a0 -d 0×0483:0xdf11 -D p3_0.3.bin -s 0x8020000
