Resurrecting Older TT GO 730

I have a GO 730 that was working but through connection problems acquired the Malformed... Error in TT Home. I backed up INTERNAL and Storage to two folders and did some resets, formatting and pasting the files back but the Malformed error remains and now getting the No Maps Found Error. I ran F/A which I got from another forum, supposedly up to date, and it ran without error except telling me about the date on the "Integrated meta.txt" having a date of 4/16/2019 in red (Don't know what the significance of that is) and I still get the No Maps Found error. Have wasted a lot of time on that so please get me oriented. Map is North_America_2GB 9510 but application is 9541.
I can't search No Maps Found here.
Anybody know where to begin? Thanks

Yes you have waisted a lot of time so start reading very carefully

After you have read it carefully you know that without a meta code
activate and downloading a map is a waste of time.
and North_America_2GB 3010_9510 has no meta code
