Hello, community 
This is my problem:
Yesterday I tried to root my S3 Mini but something went totally wrong.
I've tried about 5 firmwares (various versions of cf-root and a "Rooting Kit" which was adjusted to the S3 Mini, according to the website at least) so far, all giving the same result: The first part of the boot screen saying SAMSUNG GALAXY S3 MINI appears, but the process stops there and nothing's happening until the battery dies.
Then I tried to put the original firmware back on the phone, which I downloaded from Samsung LIVE. Same result.
Nothing's working anymore, except the ODIN Mode.
Is there any way to get my phone working again? It would be great if the data wasn't lost, but that's not the main thing. I just want my phone to be usable again.
