Hello.
Well i have a problem with my sony ericsson w595,
i have tried to fix it but i can't.
The problem is that the mobile is rebooting by itself once in a while.
I tried to connect it with the pc in order to update it, but the phone must be turned on and used in phone mode to be updated, but when i turn on the phone and connect it to usb, it reboots, so the connection is lost every 30-40 sec and i cannot do anything.. If i connect it when it is turned off the only option is mass storage, which is not the appropriate.
If someone knows something about this, i would appreciate it a lot if he/she could help.
thanks in advance.

Check your battery, could be on its way out. Also check your connection for the fast port, give it a clean and see, my old w995 had that problem, good luck!

Use Sony Ericcson Update Service(SEUS) rather than PC Companion.
It uses a different way of connecting which i believe may be ur solution. . And oh it seems that it is now Sony Update Service(SUS).
