Acer Jade s57 root flash failed, can’t start the phone

Hello everyone.

I’ve tried to root my Acer jade S57 with the smart phone flash tool v5.1444.00 and the process didn’t went correctly.
I followed the steps here : http://ift.tt/1Yzxe85
I’ve successfully flashed the recovery (download only + only recovery checked) once and it was successfull (by successfull i mean the first red bar go through, the second purple bar and the yellow one as well), but after i unpluged the smartphone, then tried to start it in recovery mode but i never managed to have any screen on, the phone vibrate as it should in recovery mode but nothing appear.
After that i might have tried different option with the soft, like a format or update.

I know i messed it up and i would like to know a way to restore the default params and get back my phone working (flashed or not) ?
Any help would be nice, thank you.
