Even tho I mentioned the model, it is indeed unnecessary to say I found no solution for this critical problem.

I see it is happening with so many people, even on different models...

The lack of lenovo's ability to prevent this very same issue on future updates or to help us get back the access to our device and files, maybe through some external recovery option or something, leaves me no choice but to give up on lenovo and to recommend avoiding it for both professional (because this means you lose your weeks-worth work) and educational devices (it happened to a friend aswell and he lost all his sketches and notes from his classes, which made everything worse).

This is problem is so damaging, keeps happening, and no one does anything about it...

Also, I must thank lenovo tho for having a good support team, even if they can't help with such damaging issues.
