Can Somebody help me to fix my samsung galaxy s4 mini?

[AC Question]

about a year ago, I broke my device.
My device (Samsung galaxy s4 mini GT-I9195) was succesfully rooted and evertything worked fine.
Untill I went to the recovery boot menu and clicked on random things.
So I (accidently) mounted my cache and unrooted my device at the same time....
then I booted the device, and it didn't work anymore. I waited for several minutes nothing happened. It was stuck at the boot screen. The only things that work are the buttons and the device can be seen by my pc in Odin mode.
PLEASE HELP!

I would go through the entire flash process again. Flash a new recovery and an up to date ROM. If Odin doesn't work for you investigate ADB commands from the download mode.
