"Then I got the official sysex ID so I released a sysex ID patch for
bootloaders that had already been upgraded to 3.0, and replaced the 3.0
bootloader with the 3.1 bootloader update. 3.1 included the new sysex ID, so
it was only a 1 step update for those who hadn't already applied the 3.0
bootloader.
I can see why that might be confusing..."

Not so much confusing as that I had forgotten the details, especially since
I hadn't been paying as close attention to p3 details recently.

"It is harmless, but since the new bootloader loads the bootloader update as
if it were a main program, a second copy of the bootloader will be installed
where the main program should be.
If you try to boot this, it gets stuck in a 'Firmware check...' loop,
because it does the firmware check, then boots the main program. but the
first thing the main program does is to reset the firmware check address
pointer and jump back to the firmware check code.
I did think of putting some code into the bootloader to detect if this was
attempted, but that would have pushed it into the next page of code memory,
losing code space that would otherwise be useable by the main program."

ok - well, I'm pretty sure that I what happened was that I loaded the 3.0
bootloader a couple of months ago, and then loaded this one.

I tried loading back an earlier O.S. last night (3988.syx) but that didn't
work.

"Maybe with the confusion around the different bootloader updates, you've
actually got the T89-3.0 release on there ?
In that case, try the sysex ID patch, and see if midiOX will load that.
If it loads and runs, then retry the current image.
That's the last explanation I cna think of, let's hope it works..."

Well, I definitely have loaded both bootloaders. I think that's what you
mean. So I can try this and see what happens.
