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? D:
-
So you did the complete format, or just deleted the OS?
-
Yes, since the previous options didn't work.
-
Answering yes to a two option question... XD
-
I think something like this has happened to me before. I guess you might have to unplug and replug the battery. You only need to unscrew the "upper screws" to remove the battery cover.
-
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. :D 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?
-
It's not exactly idiot proof, you have to be careful to make sure you don't bend any of the pins that the battery plugs into (I actually did that once, but I was able to get it to bend back to normal position). Since then I've gotten the hang of unplugging and replugging it, so it hasn't happened again.
-
Found the warranty. It says I've to try replacing the battery before I return the calculator. The warranty also says it become invalid in case of improper service :s
And there's nothing about replacing the battery in the manual (it just says rechargeable AAA batteries is strictly forbidden and other useless stuff..)
I found a video about how to replug battery on TIs site link (http://education.ti.com/educationportal/sites/US/productDetail/us_nspire_battery.html) (Now I know you should unplug the white thingy from the calculator and not the cords from the battery, heh..)
But I don't find any videos or tips about how to unplug it. Help?
-
There is no big secret to remove a battery, basically the hardest part is to get your fingernails under the "plug-piece", after that you have only to pull carefully.
-
I've tried with installing the newest OS (both from their homepage and the safe copy on my computer) but
What happens exactly after OS reinstallation?
-
This is actually a problem with running the non-CX version of gbc4nspire. That version assumes that the screen buffer is in SRAM at 0xA4000100, and it writes pixel data there. Apparently some stupid code assumes something about that RAM during boot, which causes a failure to start the OS if that RAM holds invalid data. This actually explains why this glitch could have happened to Critor even without Ndless. It also explains why unplugging the battery fixes the problem, because the RAM loses its data.
-
Hey everyone, I'm having the same problem too. The only thing is: I can't do the steps OP mentioned because they don't do anything.
I see the grey screen with a clock for some time but then it dissapears. Holding Doc+Enter+EE and pressing ON also doesn't do anything. Any advice?
Also, how the heck am I supposed to remove that battery?! That plug is so tiny. Would it be bad to pull hard on the cord to get it out?
-
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

For those with the same issue, could you please check whether the following alternative procedure found by simonsimons34 works for you?
- Hold the the following keys at boot time: Esc+Menu+Minus
- This brings the diagnostics menu. Then run the NAND tests (I don't know which option it is)
- Exit the diags software. The OS will hopefully boot normally.

i exdently uninstalled ndless how do i get it back
-
I'm not sure to understand your question, but the user guide may be what you need: http://ndlessly.wordpress.com/ndless-user-guide/
-
I tried all the above, Ndless still wont reinstall S.O.S.
-
Well if you don't describe what goes wrong we can't help you.
-
Well i got ndless now my calculator keeps restarting again and again, i cant stop it.
-
use the maintenance menu and you can reinstall the OS. That should get your calc working again, but it will completely remove ndless.
This is basically the end-all restart, but it shouldn't remove your documents.
to get there, hold Doc+Enter+EE while rebooting. When the menu comes up, press T, then 1. After that, use tilp or ti-connect to install OS 3.0 when it asks you to.
-
i tried but it says put new battery and stuff
-
hello, i have another problem with my ti cx
my ti will restart and in the middle of the reboot it shows "system error" and a low battery sign
and after that my ti closes (it just stops at the middle of the reboot bar and closes) (so it not a reboot loop)
i cant get to the diagnostics menu and the maintenance menu says "replace batteries and try again Press any key to turn off"
Please help me!
-
Have you tried charging your battery ?
-
The cx comes with just a rechargable battery, and can't use AAAs. Iirc it's still removable tho, albeit under a screwed-on cover?
Try booting it while it's plugged in, so it uses the usb as a power source.

I know I have one :P
But in France, we have a difference between one battery (which is said "batterie") and batteries (which is said "piles"). So I got confused and said "batteries" instead of "battery". Editing post.

ive tried pluging it up with USB and booting it
doesnt work:(

Please help me!
The TI-Nspire CX battery is only charged while the OS is running, or with the charging test option from the diagnostic software.
With a low battery (charge below 30%) you cannot access the maintenance menu, even connected to an external usb power source.
For your problem, the only way out is to charge the battery.
I understand that your OS doesn't boot and gives you a system error, which allready happened to me.
But why aren't you able to access the diagnostic software?...
If you've damaged your diagnostic software, then the only ways out are:
- to remove the battery from your CX and charge it by plugging it into a compatible device or by directly connecting electric wires
- to have someone with a CX lend you his/her charged battery while you access the maintenance menu to remove the OS and if it's not enough reformat your NAND ROM

accidentally delete the ndless directory :'( , in my calculator (TInSpireCAS with click pad )restarts indefinitely, as I can recover the system
[MENU] + C: Option (Delete All)
I thought that refers to erase all the current folder ;D
solved :w00t:

The TI-Nspire falls into a reboot loop
Reboot the TI-Nspire, by unplugging the USB cable, then removing and putting back a battery on classic TI-Nspire or by pressing the reset button on TI-Nspire CX.
Enter the maintenance menu by turning it on while holding the following keys until half (1/2) the progress bar:
with the ClickPad keypad: [Home]+[Enter]+[P] then[ON]
with the TouchPad keypad or the CX: Doc+Enter+EE then ON
If the maintenance menu displays the message “Replace the battery and try again“, see below “The TI-Nspire CX falls into a reboot loop and ran out of battery”.
Select ’2′ to uninstall the current OS. Reinstall it when asked to.
Next time make sure to never delete the file ndless_resources.tns as long as Ndless is installed. To uninstall Ndless, ndless_resources.tns should be opened first from the Documents screen, then deleted.
For those who have any contact with TexasInstruments Calculators , add an option to lock folders accidental erasure

Yes, that worked for me! Thanks for sharing that non-battery-pull solution! My fingernails thank you!

Not sure to understand what you're saying : there is already a popup asking for the user to confirm the deletion of a folder/file.

I just would like to thank you as this worked for me when my calc was stuck after I had to reset it running Linux since it wouldn't close.
