When performing the downgrade I must have accidently selected the wrong image file and ended up with YE05.

I should have read the post dedicated to this because I forgot to replace the dll and that is how I ended up with YE05. The strange thing is that I unistalled Activesync and the modem drivers are working properly. SamsungPSTlite sees the phone and is able to get the info off of the phone (SW version, etc..) but once I get the phone in PDA Emergency mode the download Eboot is verified and it hangs on the waiting for download screen.

Any ideas?
