Put Site into Maintenance mode to Upgrade. Upgrade failed. How remove "Maintenance" Mode Now?

Permalink
Put 5.5.2.1 site in "Maintenance Mode", updated Addons and got everything working.
Then backed up DB
No longer found familiar interface, could not find where I clear the cache and disable it in order to upgrade.
Went to Update page was offered 5.6.3.1 and 5.6.3.2 for upgrade.
Read about both, decided to select 5.6.3.2 because of the write up saying is had many code fixes.
The upgrade failed yet again. Concrete5 appears to be the worst CMS in history for upgrades!
Why offer something that always fails?

Now there is this new mess with being in "MAINTENANCE MODE"
How do I get out of it now that the site has FAILED to upgrade?
What am I supposed to do?

Searched on forums and I find nothing. Thanks.

Thanks, found out a little late. Ended up going back to previous DB and loaded it. Then tried upgrades again, after saving db upgrading addons several time successfully. This time for some reason it did upgrade from 5.4.2.2 to 5.5.2.1 without complaint
