Problem with Exam mode HP Prime 2

[eduardobueno99]

My HP Prime G2 calculator is stuck in the basic mode and exam mode settings. The keyboard is not working, it only shows the current version.

I have tried restarting the calculator by resetting it and pressing the buttons, but it didn't work.

I have opened the Connect Kit via computer and tried to delete the exam mode, but apparently that didn't work either.

In short, the calculator is stuck in exam mode and the keyboard is not working, only a few keys on the black keyboard are working.

Has anyone had a similar problem? How did you solve it?
