My Nspire CX CAS is healthy again. <3

Using nails didn't work for me :s. My mother took Nspire to her work place since she thought there would be electronic -pliers. But they weren't needed since it was quite easy with this kind of knife


When I started to load the empty battery, the damn clock screen appeared. But suddenly the language- and the other settings popped up and now the calculator is fine again. Thanks for the tips everyone!

@insertcoolnamehere: You remembered to press reset? I don't think it's a good idea to pull the cords :s

Yes I do confirm that I've had this bug on CX even without using Ndless.

Removing the battery was the only way for me to skip the "gray" screen.

So it's a bug.  Which means the warranty should cover it? (I'm guessing installing Ndless makes the warranty invalid. But after the complete format there shouldn't be any trace of Ndless..)


Or is it idiot proof to unplug and replug the battery?

Well, I installed Ndless 3 to my Nspire today. Now the screen looks like that.
Details: I put a non-cx cas gbcemulator on my calculator and clicked it and then the screen froze. Then I removed the Ndless-map with the resources.tns with the Student Software on my computer.

Apparently that was a stupid thing to do:

Do not delete ndless/ndless_resources.tns as long as Ndless is installed, as it can cause a reboot-loop that can only be stopped with a complete reformat & OS reinstallation.

I've already tried all this:

If the device is a TI-Nspire CX or TI-Nspire CX CAS, begin by holding down the reset button. With the reset button held down, press and hold the [Doc] [Enter] and [EE] keys. Release all keys at the same time. The device will boot up as in the previous reset, but will display a menu with the following options. Please try options 1, 2, 3, and 4 in that order.

1. Cancel - The most non-intrusive reset option; no changes are made, the unit restarts.
2. Delete Operating System – The operating system will be deleted without deleting any documents.
3. Delete Document Folder Contents – This will delete the user’s documents, but will not delete the OS.
4. Complete Format – This will delete the OS and all documents for a total erase of memory.

I've tried with installing the newest OS (both from their homepage and the safe copy on my computer) but

I haven't tried to remove the battery since I only have a screwdriver for the upper ones.

So, what's next?
