Is the easiest method the one given in the nlaunchcx readme file?
0) backup your documents from your nspire on your computer
1) install the 3.1.0.16 boot2, usually known as "3.1".
If you have installed OS 3.1.0.392, 3.2.0.1212, 3.2.0.1219 or 3.2.3.1233 you
already have it. If you have installed any newer version, you probably will
not be able to easily install the 3.1.0.16 boot2.
Otherwise, install OS 3.1.0.392:
CX CAS:
http://ti-pla.net/a3718 CX :
http://ti-pla.net/a37172) get a compatible OS. See
http://tiplanet.org/forum/archives_list.php?id=OS+Nspire - NOTE: Not all TI-OSes are compatible with nLaunch.
OSes 3.1.0.392, 3.2.0.1212, 3.2.0.1219 and 3.2.3.1233 are.
For a full list of compatible OSes, check src/patch.c
3) use TNOC (
http://ti-pla.net/a1922 ) on the OS upgrade to remove the boot2
(you can remove the examples too)
4) rename the TNOC'ed OS to phoenix.tns
5) transfer phoenix.tns to your calculator in the folder /nlaunch/, being at
the root of the user-accessible part of the file-system
6) get to the CX folder
7) transfer nlaunch.tns and preloader.tns to your calculator in the folder
/nlaunch/, being at the root of the user-accessible part of the file-system
if you have installed it on OS 3.1.0.392, uninstall Ndless by launching
ndless_resources.tns
9) reboot (the reset button is the easiest way), go to the maintenance menu
(
http://ti-pla.net/t5360 ), delete OS (option 2)
10)reboot, transfer nlaunch.tco/tcc to your calculator (an error will certainly
be shown on the computer, check if it is ok on your calculator)
- /!\ the initial exploit can fail. If the progress bar is stuck at 60% and
nothing is shown (you should briefly see "YZ") at the top left of the
screen, reset and send nlaunch.tco/tcc again.
- /!\ getting to the OS the first time can be fairly long (max 3 min); the
progression bar can be quite unstable. If the bar did not move at all
during 3 minutes, consider the boot as a failure
- NOTE: unplugging the USB cable "at the right time", i.e. after sending
the TNO/TNC and shortly after the bar has reached 60% again, may increase
the reliability of the installation procedure. Likewise, the second
generation of Ndless (1.7/2.0) worked better when USB was unplugged.
11)enjoy :-)
- /!\ when rebooting, the progress bar can sometimes be stuck a 60% with
nothing shown at the top left of the screen. Simply press "reset" until it
works.
NOTE: if it is working fine and you want nLaunch to be more stealthy when
booting, you can compile a quiet version ("DEBUG 1" in nlaunch.c).
Seems pretty complicated. I am confused on how to find a compatible OS
