Then you didn't only select the wrong files, you also skipped at least one important part of the how-to.

I'm sorry, but your calculator is now bricked beyond repair by any software tool.

To repair it, you'll need to buy an USB/TTL interface, and connect it like this to reflash a Boot2 image :

Actually it is very beginner friendly. You just have to be very careful and read everything twice. I've also briked one nspire :D

As far as I know, everything is written in a very comprehensive way, together with captures so that you can check at each step.

The USB/TTL interface should't cost more than $5.
I've got one; if you can ship your calculator to France, I'll gladly repair it for you.

It's not difficult if everything goes well.
You'll have to :
- install a software supporting serial ports and Xmodem transfers (ExtraPutty for example)
- connect to the new COM port @ 115200 bauds; Data bits: 8; Parity: Even; Stop bits: 1; Flow control: None
- put the calculator into Boot2 receiving mode by holding :nsdo: :nsen: :ns2: while performing a reset
- send a 4.0.1+ Boot2 image using Xmodem (for example archives_voir.php?id=481757 )

You can just type "usb ttl" in your favorite marketplace.
For example :
https://www.ebay.com/bhp/usb-ttl

Note you'll need male cables for the calculator side, and you'll have to secure them on the Npire Dock connector as pictured :
39

If you're not sure I can do it for you; I'm not charging anything for the service; so twice the shipping fees should still be less than a new TI-Nspire price.

My Calculator is bricked and every time I try sending the boot2 img file in RealTerm it gets about 1/3 of the way through and gives "Download error: 255BOOT1 Error:" "Halting boot due to download error.". When I tried ExtraPutty it only manages to send 4 packets before it aborts. How can I fix this? I'm using Windows 10.

Edit: I managed to get it to send more of the boot2 img file. Wish me luck. It turned out that I had to click send less than a second after resetting with the key combo.
Edit2: After that finished it now says that there is no DIAGS and no BOOT2 image.
Edit3: It turns out my calc was rebooting during the transfer. It seems to be working better with ExtraPutty.
Edit4: After 6 hours of work, it finally worked. Yay!!!!

I tried installed CAS on my Ti - Nspire CX and I got an X in a circle on bootup

Image

Image


After I tried to do :nses: :nsme: :nsmo: I got a clock screen that wont go away

Image

(Images borrowed from other replies)

Ive read through each post on this thread and not one matched my problem exactly but I was able to find pictures of similar screens. When I do :nses: :nsme: :nsmo: my computer makes a sound that it recognizes something is plugged in now but my TI-Student Software doesn't recognize any calculators probably because it is stuck on the clock screen

Any help is appreciated thank you!


(If I need to buy a USB TTL interface will this have everything I need? https://www.amazon.com/DSD-TECH-Convert ... dpSrc=srch)



And if I do need to use putty can I get a clarification on what to do after I put the settings in? I don't want to mess up the wiring
