Hi everyone,
 
I'm a bit nervous about the situation, first of all I hope that i'm writing in the right place. If it's not the case, feel free to move this post.
 
To explain it briefly, I tried to set the root mode on my S8+ thanks to Odin v3.10 and I went to the Downloading mode. But during the installation, I think I unplugged the cable a bit too early.
 
So my phone now is automatically rebooting, (display an image with android logo in a blue screen and 'deleting').
 
And when I try to go again in the downloading mode, it display "downloading...".
 
I tried to relaunch the Odin flash but it doesn't work and ask me to restore my phone.
 
I tried to set the root mode to get important data that I accidently delete, it's very important for me and now I don't even know if I could get all my data back....
 
Thanks for your help, and don't hesitate if you need more precisions.
