Broken homey pro 2019 not turning on

Hi, all lovely people.

I got a Homey Pro 2019. Someone was giving it away because it was broken.
It doesn’t turn on. The connector ribbon does not sit well because the i/o port seems broken (the small brown thingy that holds down the ribbon is missing). But on forcing it in and some angle, it makes cracking sounds a couple of times. Nothing else, no LED or anything.
Is there any hope? Or should I throw it away?
