Default [Q] Ace II i8160 with power button HS

Hello,

I have a samsung galaxy ace 2 i8160 with power button HS, i have tried to change it but no success.

I can start the phone when i start in download mode ( combination button with insert battery) but i can use recovery mode ( power button HS).

Is it possible to root the phone with Odin or other , but not with recovery mode?

Is there an pre-rooted rom flashable with odin?

Thanks for your help.
