Thanks for the suggest, but I send the phone to the Sony Ericsson assistence. I tried the sony ericsson update service, but when the cel reboot , the updater can't detect him.
THe sony ericsson assistence, give me back my cell with another face plate and fixed, but the IMEI was changed, I think the SE put away the old damaged main board and put a new one on it, put the new frame and send me back... easy to fix when you have all the pieces =)

Thanks a Lot, and this post may be locked !
