Answer 1

Change your ADB connection time-out i think that is causing problem.

If you are using eclipse you can go to Window -> Preferences and then it is in DDMS under Android.

Window -> Preferences -> Android -> DDMS -> ADB Connection Timeout (ms)

By default it is 500ms change it to 10000ms.

Got this off an Android forum where I asked the same question. Hope this helps somebody else.

On a terminal emulator on the phone:

mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system

Then on the cmd prompt, do the adb push

This same thing just happened to me because I already had an emulator running. Make sure you don't already have an emulator running.
