I have not upgraded the software in my older Nspire for over 5 years or more! Can someone tell me how to do this so I can be active with my tinspre again, please? Thanks

Hello John,

If it was over 5 years ago, then your calculator (which must be a Nspire
Clickpad) has a boot2 older than 1.4.1571. Therefore, in the current
state, attempting to transfer the OS 2.1.0.631 or newer versions will
result in a failure to launch the OS...
First of all, you need to transfer e.g. OS 1.7.2741, which contains that
1.4.1571 boot2 version, which remains able to deal with OS 2.1.0.631,
and even the most recent OS version, AFAICT.
Afterwards, you can either:
* transfer OS 3.1.0.392 to further update the boot2, and later, upgrade
to 3.6.0.546 (latest version for which there's a port of
http://ndless.me ) or 3.9.0.463 (the newest publicly available version,
at the time of this writing);
* stick to boot2 1.4.1571 (it works, after all), and switch to the
nLaunchy ( http://ti-pla.net/a12130 ) way of launching OS. This way, you
won't have to put up with TI's silly anti-downgrade protection and you
can switch between multiple OS versions (
http://tiplanet.org/forum/viewtopic.php?t=13213&lang=en ).
The second way is more powerful and leaves you more freedom.
The first way is easier, but leaves your calculator and your usage
thereof subject to TI's whims. That is, locking people onto newer
versions (after they have been transferred to the calculator) which are
larger, at best not faster (often slower), bring little in the way of
new features, and take away the power of native code, as happened once
again with OS 3.9.0.461/463.
Hope that this helps :)
Bye,
Lionel.

Contact 800-TICARES (US and Canada) for the official information. Other countries have similar services.
My advice: ALWAYS update your devices (computers, tablets, phones and calculators) when anything becomes available.
Exception: Mac OS updates always seem to cause problems.

As far as Nspire calculators are concerned, John's advice of always
updating them when any software update becomes available is questionable.
You'd better wait for a little while, to let the most severe problems
surface on other persons' calculators, before they get in your way on
your own calculators / your students' calculators ;)
Over the past three years, as reported on this group, problems and
misfeatures in new OS upgrades (besides the usual increasing RAM
consumption, document format backwards incompatibility, anti-downgrade
protection, reduction of functionality caused by closing access to
arbitrary native code) have included:
* a whole range of bugs in math functionality which the TI-68k and
Nspire series never had for 15 years. It took multiple releases for most
of those bugs, introduced by OS 3.0.1.1753, to be fixed (assuming that
all of them are now fixed ?).
* the same OS 3.0.1.1753 was even worse than math bugs: the defective
boot2 upgrade procedure embedded into that OS left at least hundreds of
Clickpad / Touchpad calculators without a valid boot2, meaning that they
were both unable to boot, and unrepairable through the sole equipment
provided by TI.
USB - RS232 TTL adapters are cheap, but most people don't have them
handy, and anyhow, there are more productive ways to spend one's time
than having to reflash the boot2 in Nspire calculators bricked by faulty
OS upgrades.
* additional slowness resulting from e.g. font rendering changes, or a
document format even more bloated and stupid than it used to be.
nLaunchy resorts to overclocking the calculator (at safe frequencies, of
course) to counter the bloat.
Of course, new OS upgrades have also brought some functionality that you
may find useful for your own purposes. TI's release notes describe most
of those changes... but not the drawbacks and hidden costs.
