That sounds like you're trying to load the bootloader update when you've
already got the new bootloader installed.
You already have the bootloader updated, so trying to load it again won't do
anything useful.

And this is using the latest build of P3Tools ?
The bootloader update, as well as relocating the bootloader in memory to
support the new CPU type, also changes the sysex maker ID.
If you use an older version of P3Tools, it will send the old sysex ID, which
would give 'BAD DATA' warnings.
Check you've definitely got the latest P3Tools build. If it still gives you
BAD DATA, try MidiOX.
