Ah, sorry, i've forgot to update my post.
I tried ODIN to get CWM and 2.3 GB beside but my infuse get bricked... (Option C, in infuse 4G dev' forum )
In fact, it was stuck on samsung logo while booting, after the flashing
I've tried one-click unbrick, and, curiously, despite the "successfully unbricked" status, my phone get hard bricked.
It don't boot at all. lol
So...Can i send my phone to service center or something like that ? Or, it's dead for ever ? :'o
PS: Sorry for my english, again. I'll try to do my best.
