Failed o2 rom flash

[monkeyharris]

hi there, i hav an o2 xda 2, that i managed to flash to 1.72 rom, but now i would like to sell it so i tried to flash it back to the original o2 rom (with all the o2 interface etc) and i get an error message saying "ERROR 100: MODEL ID " and then it all stops, so now i hav an xda2 with a blank screen, that says serial at the top and v1.03 at the bottom in red. windows picks up that the device is there wen i dock it but i cant drag any files on to it at all. im completely stuck now :( havnt got a clue how to get it back to how it was, all i want is it to be back to normal. can anyone help? cheers

OK. Try this:
1. Press Power+Navi-key+reset in one time (you will be in bootloader - that screen with Serial 1.03, if you put it into cradle, it will change to USB 1.03)
2. Kill ActiveSync in Windows (wcescomm.exe process) using Task Manager
3. Put XDA2 into cradle
4. Run the update again
