active sync is back !
after days of deep dive, i found out that even if your device is dead you can activate the usb by :
-turning on the device
( without usb plug
)
-keep pressed the power button, insert usb plug
( while keep pressing the power botton
)
-after 15/ 20 seconds active acive sinc is connected !
I can browse the content of the device and use register work shop
unfortunately during many previous attempts I used the format tool. so I have maybe deleted more stuff...
