Add 3.1/Ndless compatibility to your TI-Nspire CX HW-J/K
« on: October 29, 2013, 12:18:20 pm »
As explained in a previous news, changes on the motherboard in new TI-Nspire CX hardware revision J and above are making them incompatible with versions 3.1, and thus with Ndless / nLaunch.

A Chinese online shop nosed the bargain and has started selling hundreds of TI-Nspire CX spare parts: 3.1 compatible TI-Nspire CX motherboards, thus compatible with Ndless / Nlaunch. ;D
The motherboard reference is Firebird Color MB 6421. So it's the motherboard used in the initial version of the hardware, prior to hardware revision A.

Currently there are:
  • 200 TI-Nspire CX motherboards  at 200 yuan each (about 25€ or 35$)
  • 50 motherboards TI- Nspire CX CAS for 300 yuan coin (about 35€ or 50$)
An affordable and easy to install motherboard for new extraordinary possibilities with your TI-Nspire CX! ;D

We tested, and installing the old motherboard together with the more recent keypad board doesn't cause any problem. ;D

Note that the TI-Nspire CX and TI-Nspire CX CAS motherboards are apparently identical.
But do not attempt to turn your TI-Nspire CX intro a TI-Nspire CX CAS with a TI-Nspire CX CAS motherboard, because it just does not work . TI knows of this method (commonly called 'case-switching') and has made things more difficult than that: as the motherboard, the keypad board has the CAS and non-CAS types too. If you mix the types, the OS does notice it when launched and will either:
  • display a blocking error message about an incorrect keypad
  • reboot automatically
You would need to buy the CAS version of the TI-Nspire CX keypad board too for such a purpose, of course if you can find such a spare part.
Note that it may be possible to bypass this protection by using a current or future version of nLaunch, although it has not been tested yet. But even in this case, it would be dangerous to be forced to use Nlaunch to make your calculator work, when TI clearly wants to make everything possible in order to block it.

Interesting trick. I wonder if it's easy to switch or if it requires some soldering and stuff? It could be a particularly risky move for people who have no clue what they are doing.

No soldering required. :)
The board is just clipped and screwed.

The screen flat ribbon is just inserted in a clipped contact.

Ah ok. I was worried about it being tied to the mobo and requiring some special glue or extreme care to be connected to a new one.

At least I'm glad swapping mobos works, since on the Xbox 360, you can't even swap an hard drive without flashing it first. That said, knowing TI, the days until this stops working are most likely counted, although I doubt they can do much about the store re-selling those motherboards, since it's located in China.

It was the case on TI-Nspire ClickPad/TouchPad.

It's not the case anymore on TI-Nspire CX/CM :)

So I just reveiced mine today ;D! Delivery took 3 Weeks, but what do you expect when it is coming all the way from China (shipping was free)!

Anyway, just wanted to say is that they sent me a Firebird_Color_MB_6422 and not a Firebird_Color_MB_6421, as displayed in the description!

Edit: It's the CAS version btw :)

Hmm I hope that not too many people get the wrong board (at least not a non-Ndlessable one). Welcome to the forums, by the way! :)

Thank you for the report.
FireBird_Color_MB_6422 is still fine.
I hope you'll be happy with it :)

I doubt they're going to have spare parts with the J/K motherboards soon anyway.
But I suppose you can still tell the seller to check that the motherboard reference starts with "FireBird_Color_MB_64".

I used Google translate to get around the site, it runs quite well! Confirming your registration on their Website is done by SMS (there is an option for email registration but it didn't work for me...)
You can only pay by Credit Card. There is an Option for "Paypal" but that's Google translate mixing up the Chinese equivalent of PayPal, Alipay with the western used PayPal! After that it will automatically register you to Alipay, where, when you are prompted on your profile page, will need to confirm the payment. After that you just have to wait the 3 weeks (depends :)!).

Well, I meant about the switching itself but the information you told can be useful for many people, so thanks for that :)

Still such a pity that now we have to resort to hardware mods. However, this method is better than nothing!
Due to dissatisfaction, I will be inactive on Omnimaga until further notice. (?? THP hasn't been much success and there's also the CE. I might possibly be here for a while.)
If you want to implore me to come back, or otherwise contact me, I can be found on GitHub (bluebear94), Twitter (@melranosF_), Reddit (/u/Fluffy8x), or e-mail (if you know my address). As a last resort, send me a PM on Cemetech (bluebear94) or join Touhou Prono (don't be fooled by the name). I've also enabled notifications for PMs on Omnimaga, but I don't advise using that since I might be banned.
