Hello,
Unfortunately, uploading a backup to a device with a different product code is not possible. Even if the device models are the same, the product codes must match in order to use the same backup file.
I also noticed that you have already created a similar topic on our forum: RUT240 *6**** and RUT240 *D**** Back up
Therefore, I kindly ask you to continue the communication there. You will receive a reply from us shortly.
Thank you.
Best regards,
