Omnia firmware update - 'image upgrade failed'

[Guest OZZIE9]

hi all, want to upgrade my samsung omnia ROM to a version from a different country (Singapore). Have edited the current firmware version in the registry and used hex edit to change the updater, per instructions at the following link

The updater verifies my current firmware, but then gives the following message:

"Image upgrade failed, please manually reset the device and execute the program again."

hope someone can help. The following is the only other reference I can find to this problem.
