It's just about connecting 3 wires - no need to know anything about electronic and I'm not an electronic dude at all either.


Yes, after reflashing Boot2 3.1, installing Nlaunch, launching OS 3.1, and installing Ndless, you'll be able to run C/assembly programs and PDF/image readers.

Boot2 reflashing apart, other steps only use softwares, are easy and pretty well documented online.

So, After I do this, What will my OS actually be then?
3.1 OR 3.6?

When Boot 2 "ignores" the minimal installable OS version set in memory,
what does that leave me with basically, is what I'm asking.

Thanks,
Stefos

P.S. It looks like I have to spend $10 for the contraption from amazon.com
Can you take a look at it & tell me if that's the one to get please?

Merci

After you've installed Boot2 3.1 and Nlaunch, you can run either OS 3.1 or OS 3.6.

You can even have both OSes together in your TI-Nspire and switch between them when needed.
Check this: http://tiplanet.org/forum/viewtopic.php?f=57&t=13213&lang=en

Like I said above, everything is possible ;)

Hi again,

Well....I went to the TI planet link you gave me & my boot 2 code version is 3.2.4.7...This is o.k right to take it to the next step
you mentioned?  It seems so.

Can you please let me know?  Also, Did you look at the amazon.com link I embedded?  Is this what I should buy?

Thanks,
Stefos

No, Boot2 3.2.4.7 is not ok for this tutorial.
You need Boot2 3.1, and that's why you need to reflash it first using an USB/TTL interface first.

I could see no amazon link embedded in your post.

Understood completely.....Thank you

Here's what I intend on buying as I have Win 7 professional...
http://www.amazon.com/NooElec-Adapter-Harnesses-Jumper-Compatible/dp/B009GXEF8A/ref=sr_1_4?s=electronics&ie=UTF8&qid=1386856661&sr=1-4&keywords=usb+to+ttl+converter

Will this work?

Merci,

It looks ok.

Thanks, so I'll place an order for it & post back when I get it to get help in actually doing what needs to be done.

I've never did this before!

Merci,

Stefos i'm pretty sure all you do is push up the bottom part of the cas stick your three wires in, put them into your ttl/usb converter and plug the usb

into the computer. Then you flash boot2.img. Its in any ndless file around on ti-planet.

Yes but you need to be very careful where you put the 3 wires, to prevent short circuits and/or frying your calc.

From what I read, critor made it sound like this couldn't happen.

So, since I don't know what I'm doing....I'm taking a BIG risk trying to run 2 OS's on my calculator.

I thought this would happen.......  This is NOT cool.

I don't think I'm going to do this folks unless someone can show me IN PERSON....
It's much too risky.

Thank you.......I should not have upgraded, then maybe I wouldn't need to go through all this mess.

@DJ Omnimaga: do you have a source about this ?

Unwanted contacts with adjacent pins happened to me many times.
And it never bricked the calculator.



Anyway, here's the complete process:

- remove any OS using the maintenance menu (hold Doc+Enter+EE while resetting)

- download a Boot2 3.1 image for the TI-Nspire CX:
http://tiplanet.org/forum/archives_voir.php?id=4617

- connect and secure the three Tx, Rx and GND wires to the Dock/J01 connector


- install and run a compatible terminal software (like the Hyperterminal private edition coming with Windows up to Vista)

- configure it with:
* the right COM port (check your device manager to know which one your adapter did default to)
* Baud rate = 115200
* Data = 8 bit
* Parity = none
* Stop = 1 bit
* Flow control = none

- trigger the calculator Boot2 update mode be resetting while holding Doc+Enter+2
(beware, they will be a timeout - just reset and try again if you're not fast enough)

- from the terminal send the previously downloaded file using the Xmodem protocol

- install one of the available Nlaunch packs

@DJ Omnimaga: do you have a source about this ?

Here: http://ourl.ca/18458 (After the person tried the Nspire Audio player)

I have to wonder if it's not a combination of this plus other things, though, such as previously running a bad Ndless program or doing a mistake with another (for example, setting Nover to dangerous AHB frequencies), then attempting to use the audio player?

In February 2002, I once bricked a TI-83 Plus Silver Edition just by trying to group archived programs together through an OS 1.13/1.14 (83+SE-only) bug before. The result was random, since in one occasion it just resulted in a calc freeze, but I suspect that this bug could result in overwriting random parts of the memory including the certificate, since in the other occasion nothing could bring the calc back.

Okay fellas!

What's going on here?

One person is telling me: NO problems if you screw up

The other is telling me: BIG problems if you screw up

I know it's my fault for upgrading but this is a tad wee too much.

Can someone please clarify?

Thank you,
Stefos

A non-responding TouchPad happened to me many times in various situations.
The post isn't comprehensive, so we can't even be sure a shortcut was  the cause.
And he didn't reply after being told how to remove the battery (full reset as some things like the SRAM aren't properly resetted with the button on the back).

Anyway, the pin for the audio player is not adjacent and completely different.
