No connection to ActiveSync is needed to load a ROM.

However, it seems like your bootloader is jacked if it shows both 1.2 and 2.4.

Try a hard reset and see if you can get to the welcome screen. If you can, don't proceed any further. From there you should be able to get an AS connection and reload the 2.4 bootloader.

If that does't work, look back through the steps johnw suggested and try them.
