Cant restore after 3.20.06 ROM upgrade

[rhills]

Hi All,

Today I upgraded my O2 XDA ROM and Radio Stack to the latest "official" versions (3.20.06 ENG and 4.21.00 respectively). I followed the instructions carefully, particularly WRT backup.

However, when I tried to restore my backup after the upgrade (via M$ ActiveSync), I get a "Device Mismatch" error - "Restore cannot be completed successfully. The selected backup file was created from a different type of mobile device...". It wasn't of course and I suspect that the error occurs because it was a different ROM version.

Anyone any ideas how to work around this? I saw a workaround for the problem on the ipaq (http://www.pc-counselor.8m.com/How_to/index.htm#backup1) but when I looked at the relevant part of my backup file, the value they said to change from was different (the 'howto' said it should be 0600 but in my file it was 0100).

TIA,

Rob Hills

i dont know if this is correct, or the right way, but this is what i woulda done: downgrade to old rom, then do a restore

Yes, I'd thought of this approach, but concluded that it leaves me with the old version of the OS and no obvious way to upgrade without losing my data.

u dont want to restore things from an old ROM anyway, wont be compatible, or may cause problems...so I've heard
