Hi,everybody .
I tried to flash a new rom ,not the first time I did it,now my Xperia Z C6603 just boot on the Xperia screen an empty screen with light on .
Can't use Sony update,Emma,Flashtool cause the phone is quickly disconnected in flashmode .
I also tried fastboot mode in flashtool but the phone doesn't move ...!
I tried to flash with C6603_10.5.1.A.0.292_Generique_FR.ftf .
I think it's still alive because of the screen ant the battery's charging but ,after reading many posts ,trying many ways ,versions of flashtool ,re-installing drivers ,I don't know what to do !
Thanks to U if you've got time to give me an advice .
Merry Christmas to everybody !

Swith off the phone and open flash tool click flash choose rom then click flash wait till prepare the rom and only connect your phone when it is prompted in flashmode.

Otherwise

Try to drain you battery fully and try something after that

I'll try to drain my battery .I didn't think about that and nothing to lose !
I tried many times with several versions of Flashtool but my phone is quickly diconnected ,even when I connect it when Flashtool asks me .
I've the same problem with Sony Update ....
Thanks for your answer ,starting draining ...!
