My calculator ti nspire cx cas 2036000558 P - 0511c
entered in a boot loop. I tried to remove the os and reinstall the version avaible on the official site, but without resoults. i changed the battery but it's the same.
i don't known what to do.
help me please!

Hi !
1) Did you ever do something "unusual" on your calc, such as putting Ndless or so ?
2) How exactly acts your calc ? I mean : at which point of the boot does your calc reboot ?

yes i tried to install ndless to read the pdf files. For a period it worked. it going to metallic screen with the clock at center and restart.

Let's try this.

Hold before a restart, and release the keys after the screen turns back on.
This should trigger the diagnostics menu which may report a GPIO error. In this case, press to fix it.

Once at the diags main menu, just press the reset button on the back.

most of the tests failed especially: tochpad keyboard adc calibration and others.

Don't bother about them.

Just restart and check if the problem is solved.

it's the same.... boot loop

Ok, strange.

Try holding before reaching the metallic screen then.
Does it change something ?

if i hold esc the hands of the clock do not turn and then it disappears and restarts

Then try to remove the OS from the maintenance menu.
Hold before a reset.
