A couple of months ago I tried to "convert" my basic Nspire into CAS, but because I was (and still am a bit ) a NOOB, the first thing I did when I got my calc was to update the OS to the infamous 3.1.0392...
Only after a "long conversation" with Lionel, who was very patient with me ( ), I understood I couldn't have the CAS function anymore...
But since now we have the wonderfull news about Ndless 3.1 release (YAY!!), I tried to do it again following these instructions, using the OS 3.1.0392 basic and CAS, but I still can't seem to make it work... I can go through every step, except I'm having troubles in sending the ndless_installer-3.1.0.tno file to the folder ndless in the calc... Everytime I try to do it, the calc reboots and the file isn't there and I can't do any "CAS" operations in the calc...
Am I doing something wrong or is it still not possible to do the "conversion"?...
I won't risk putting boot2 v3.xxx on my nspire cuz I don't want to live with the impossibility to downgrade to OS 2.1 however it looks that ndless3 is near from being out. So maybe it is wiser to wait a while and try all Lua programs out there until it is out that to spend the time and effort on downgrading for nothing...
I actually thought about that possibility... An update that will allow to go around the lockdown... We'll see what the "Gurus" come up with!..
You're right! Don't to the upgrade! You loose too much and you gain almost nothing...
OSLauncher just launches the other OS, it does not install it in any way; just reboot the calculator and the effect of OSLauncher is gone
So I tried do install the OSLauncher... But because I'm a NOOBBB... I updated the SO when I purchase the calc... That means right now I have the "deadly" SO 3.1 and I'm stuck!...
I tried to find a solution to do a downgrade with this SO and found a software called TNOC that claims that removes the boot2 from the SO and generates a new file without the boot2. Tried that and installed the SO generated by TNOC but didn't find any difference and couldn't do the downgrade..
Then I also read that there is a way to "crash" the SO by installing it and during the instalation, swap the keypad to the TI-84 and swap back again.. or something like that.. That should crash the SO and then should be able to install any SO.. Well, I don't have the TI-84 keypad to try this, but I notice that Texas in Portugal was offering these keypads to whom purchased an Nspire calc... But that promotion was only untill June! (how lucky am I?... )... I've sent the coupon anyways, together with a nice letter see if I can convice them to send me the keypad!....
In the meantime, do you have any other sugestions of how to "kill the beast" SO 3.1?...
I will definitely give it a try! If by any chance the OSLAuncher doesn't work properly or if I decide to go back to the original OS, I can install it with no problems, right?
I'm not sure I understand correctly your problem, but the emulator communicates neither with a real calculator, nor with TI's software (TI-Nspire Computer Link Software a.k.a "TINCLS", TI-Nspire Computer Software a.k.a "TINCS").
I'm sorry, but I'm still a noob in this field.. With the emulator we can use the CAS functions on a non cas spire calculator, right? And we do this by installing the emulated OS into the calculator correct? My doubt is how to install it in the calculator..
I'm trying to install the emulator on my non-cas nspire but I have a doubt... I followed these <a href="http://hackspire.unsads.com/wiki/index.php/Emulators#Setup">instructions</a> and reached to the point of getting emulator screen to start the installation. Now, my doubt is: Should I have the calculator plugged in at this time and the OS will be installed automatically or should I let it load, then save the flash as <name>.tno and install it using the software from Ti-Texas?...
