Any time you see "Further improvements to overall system stability and other minor adjustments have been made to enhance the user experience," it's them closing an exploit vector. That would be a lot of fuses to blow.
I wonder how many of these systems have secure enclaves and some ability to have a WORM-style hardware incrementer. The SoC version of an odometer.
So despite 11 Software updates, there has only been five firmware updates.
When we're talking about fuses odm_reserved has 256 bits to play with. Assuming that one bit is 1 fuse. Then they can do 256 firmware updates before they're in trouble.
Firmware is a pretty horribly misused term these days.
There's a cheap/easy/reliable hardware exploit now, so Nintendo has given up on patching things for the 3DS. In fact, their latest firmware even opens up a new bug.
"640K ought to be enough for anybody!"
But seriously, in the 3DS world, they've been going back and forth with hackers for a long time. There are a lot of updates for that system:
