Alcatel OT918D bricked!

Hello all,

i've got an Alcatel OT-918D
Recently, i've try to root it with SP Flash Tool.
But when the load, i've disconnect the usb port so i can't boot it!!
i just can recharger it (i can see the blue del)

When i connect my alcatel in my computer via usb port whitout driver or not, i recognize it after 5minutes during 30seconds and after he don't recognize it!

Sorry but i'm french so i don't speak english very well :/

Can you help me please?

Thanks
