Ti-Nspire CX II Bootloop Issue -> Connectivity Issue

[ConcernedAlpaca]

Hello, I am writing this as a concerned college student with an exam in 72 hours. I am sending this out to a couple of forums, please do not flag me for spam..

If I do not have this calculator then I will be screwed for an exam worth 40% of my grade.

My TI-NSPIRE CX II which is the holy grail for my physics journey in my engineering career had a charging issue after leaving it to charge over night being stuck in a bootloop, I later discovered that the charging issues became more and more pronounced as I realized it would only turned in when plugged into the c omputer. I then proceeded to go to the maintenance menu and then reformatted OS before deleting OS. The day after that the new Ti battery I ordered came in and it fit like a glove, the calculator no longer had a boot loop issue, I have spent the past 48 hours trying to install the OS however, after exhausting nlink, TI LINK, getting a trial version of the CAS software to no avail, it has not worked.

for a brief moment yesterday I heard a connect sound on my computer after (maintenance menu)reformatting and resetting, I believe I did the reformatting and resetting for 4 combined hours. I also balanced this with my studies.

Together with my CS-savvy nephew, we reinstalled USB drivers, the uninstalled the old driver for the calculator that no longer worked, we also tried the student software, we took out the battery and then held the on button for 35 seconds and plopped it back in, we tried different ports, and we tried a dongle, I tried a box wire, I tried a standard microUSB wire, the calculator itself is stuck in "Operating System not found. Install OS now." I also tried deleting the OS a second time.

The main issue is that the calculator just will not connect to my computer or any of the student software, it just won't. Please help, the calculator is alive, its doing its little dance of loading but it just needs an OS, I know anything above 5.5 is horseradish, so I downloaded a 5.2 OS, it's a calculator from 2019. PLEASE HELP! Sad

Hello.


If you can hear a connect sound, then the calculator should appear somewhere.
If it isn't listed by any software, you should open the peripherals list window and check for warning signs.

There are several issues with your attempts.

TI-Nspire Computer Link isn't compatible with the TI-Nspire CX II.

Same issue with old versions of the TI-Nspire Computer software (and up to date versions don't come with a trial anymore).
So where did you get your TI-Nspire Computer software ?

Where did you find the TI-Nspire CX II USB drivers ?

You also mentioned nlink. Which edition did you try, web or standalone ?
The web edition is only compatible with Chromium web browsers, and is also incompatible with Windows.


Thanks.
