Refer to post #2 for the details of where the backup is stored, named, and how to restore them if necessary.
The issue you had may have been because you weren't using the erase EFS option. I don't know for sure. Or, you may already have an issue with your persist - refer to the FAQ " On soak test 2 or later, I have my IMEI but no signal. What can I do?" on the second post.
Thanks for the prompt reply. I will try this and post back the result/observations.
