Firsts, there is a dedicated TV list, better if you post there.

Yes, this was wrong. Instructions do not say that you can drop these
tables and hope to keep data in the tem at the same time.

So, you effectively removed all TV information from the system: DSes and

They *are* managed. But there were nothing to manage because these
tables were removed. Upgrade tool can upgrade tables, it cannot not

table and complain that upgrade went incorrectly and you lost your data.
This is the same!

If you did not touch TV tables, they would be upgraded just fine.
