I'm having the same problem with my phone, but I'm unable to get SEMC version 8.4 or 8.7 to function for me. I have the multiserver cable, which I also assigned to COM1, but it just sits there waiting at "switch phone on". I am able to flash the phone with xs++ and setool, I've also customized the phone, but it always goes back to the Please wait and does nothing else. Could you post some photos since you were able to fix your phone?

Thanks

Rob
