Follow the guide here for how to get adb to work.

Then do the following as it sounds like you didn't change the permissions of the build.prop after copying it.

adb shell
su
mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
chmod 644 /system/build.prop

then reboot and try again.
If you can't get adb mode working you won't be able to fix this.

good luck.

You have to uninstall the Microsoft drivers for your device before you can install the ADB drivers which will allow you to get ADBworking and make these commands. There's only a dozen or more threads already for this exact problem in the general and the troubleshooting section... And they all contain links for the drivers and explain how to uninstall Microsoft drivers etc...
