I saw this calculator a few days ago, and I found that the mark was "TI nspire CAS" instead of "TI nspire CX CAS" or something like "TI nspire color CAS"
So I asked the seller for some pictures, here they are.
By the way, the seller told me that he had a PLT-FHH1, but the screen was broken and he doesn't have the right power adapter to test.

Hey guys, I have the same problem and did some research on this as well.
I'm not trying to hijack this thread.
Would anyone mind giving some insight on what type of converter this should be?
I saw this http://www.amazon.com/USB-TTL-Converter-FT232RL-3-V/dp/B00BIF471O as it seemed most similar to http://ourl.ca/10147/196556
I am extremely new here and just bought the Nspire CX.
If anyone could provide n00b information or resources, much would be appreciated!
Yes, that is what you need to downgrade the CX. Once you got the USB2TTL, you can follow the guide to flash 3.1 boot2 into your calculator, and then use nLaunch to get OS3.1 working on your calculator.Final step, download nsNandMgr and remove the downgrade protect. Sorry for my poor English.

It seems that all PLT-FHH1/SU1 comes with a erased flash? Or they just erased the boot script so the OS is still there? This is what I want to find out.Luckily, I know many people who sell prototype nspire in China, I have told them to help me find one.
I will ask him to take a picture of the serial number.

On ClickPad/TouchPad, they were stored in the Boot1.
I haven't investigated this on CX/CM yet.
As far as I can tell from various experimentations, it seems that the Boot1, which is common to CX and CM models, knows about both CX and CM keys, but adds a model check for running the Boot2 and Diags.
But the Boot2 only knows about the model specific keys.
That's why for example you cannot directly run a CM Boot2/Diags on your TI-Nspire CX.
But if you flash the TI-Nspire CM manuf splashscreen (which have no header with the model ID unlike the Boot2/Diags) on a TI-Nspire CX, the Boot1 will accept to load the splashscreen and the Boot2 will reject it.
Edit: Sorry for the delay, but here is a better picture of the TI-Nspire Color prototype external Flash-NOR chip:
It seems to be a MXIC MX29SL402CBTI-90G.
Reflashing this with a patched TI-Nspire CX Boot1 will let you do everything you've allways dreamed of 
Ok, I will have a try after fixing my CM-C prototype.(I'm also trying to find a PLT-FHH1 prototype and read the flash with my programmer.) By the way, the guy who has a 64MB Clickpad told me, nPal works well!

The TI-Nspire Color does already have a CX Boot2, as it is a TI-Nspire CX prototype.
But its Boot1 uses the developper keys instead of the production ones.
So the Boot1 will reject all production TI-Nspire CX Boot2 and OSes, meaning probably everything you've got, and this has nothing to do with the manuf.
Are you sure that the key is stored in Nor(boot1) but not somewhere else(ASIC?)

On TI-Nspire ClickPad DVT1.2 and DVT2.0 prototype units and hardware revision A production units, the Boot1 was an external documented ROM chip, a SST 39WF400A.
The flashing tool is available here with source code, but it's essentially assembly code implementing the read, erase and write functions:
http://tiplanet.org/forum/archives_voir.php?id=10069 (Ndless 1.7/2.0/3.1)
http://tiplanet.org/forum/archives_voir.php?id=4184 (Ndless 1.1/1.2 for the 1st prototype reflashing)
On the TI-Nspire Color, the external Boot1 NOR chip is by MXIO.
I have problems reading its reference on the photo, so I'm going to open my faulty TI-Nspire Color again.
I'll either edit this post or reply in this topic.
One idea, as CM would accept CX's boot2 after mod the maunf, we could do the same thing on Color. But ndless doesn't support devbuild 3.0, so I think we need a nand programmer.

If you (or someone else) buy one of the TI-Nspire Color, be aware that you won't be able to update it with production OSes.
It includes development builds of the Boot1 and Boot2 which check the OS with the development RSA keys. So all production OSes released on TI website will be rejected.
Unlike production TI-Nspire CX, the TI-Nspire Color Boot1 seems to be included in an external NOR chip present on the back of the screen board (and missing on production units, where the Boot1 was moved and secured inside a different ASIC chip), which means it might be possible to reflash it with a production or patched Boot1 image.
This could prove be very interesting and useful
We already did that TI-Nspire ClickPad DVT1.2 and DVT2.0 prototypes.
But the chip here is completely different and so does need a specific tool we haven't developped yet.
Could you provide me with the model of the NOR chip? Thanks.

I asked the seller, he told me it just stucks at that screen, reset does't fix this problem.
For me, I don't have money to buy that. (PS, the seller has 3 nspire color, 2 works well)

Yes, we allready saw this on a TI-Nspire Color prototype.
If you manage to boot it, could you tell us the OS/Boot1/Boot2 versions?
Thanks.
This calculator doesn't belong to me and I don't think it could boot into OS successfully.

This calculator is not mine, it's being sold on taobao(a website like ebay) at 188 CNY(about 30.7 USD).

EDIT Ok it works now! For some reasons rebooting never worked, but after installing the latest Ndless version and still having no luck running the game, I rebooted once again and now it launched. So far it appears to work.
As for the game it looks pretty great! Good job so far!  , it reminds me of Super Mario RPG isometric maps. the only bugs I or other people found so far are:
1) There seems to be a little display bug causing my Nspire arrow cursor to remain displayed, although darkened, in the screen corner.
2) Text isn't aligned properly all the time, which can make it hard to follow convos.  (Mentionned above)
3) Untranslated menus, but I assume that you will translate them too later.
4) Arrows/numbers moves in the wrong direction. For example, if I press left or 4, I move up-left and if I press down-right I move down-left. Also the 1, 3, 7 and 9 keys to move diagonally do nothing.
I have finished and uploaded RC1 version,these bugs should have been fixed

The graphics are indeed pretty damn impressive. The dialogs seem a bit weirdly placed but I guess it's alright. Strangely my assumption for the quit menu item was correct ^^ Anyway, good job at translating this (or at least the dialogs), I hope you plan on translating more
[Edit: ] some images can be found here http://tiplanet.org/forum/viewtopic.php?p=139259
I will translate others in next version

Wow it looks really impressive!
But it's still Chinese.
