Factory Bad Block

Hello there!

My calculator was stuck in the middle of the loading and also could not start the DIAGS menu, so I bought an TTL-USB to try to solve the problem however, I saw that bad block that you can see on the image https://imgur.com/bMf86i4.
I have tried to reboot it in the DOC + ENTER + EE mode but np matter what function I use it end up at the beginning no matter how much time passes.

Hope you can help me!
Thanks in advance

I had the same problem on a Nspire CX CAS, and I had to flash a new Boot2 with the TTL-USB

How did you do to flash? Because mine after appearing the error doesn't let me send the file

I used this tuto : https://tiplanet.org/modules/archives/d ... air301.pdf .
Even though it's not intended for Nspire CX (CAS), it will work if you choose a correct Boot2 for your calc (4.0 for Nspire CX for example

)
