How to undo/ "goBack" in C5 version

Permalink
I have test site on wamp server - the Upgrade manually give me some errors ("An exception occurred while executing 'update...) when i try to edit blocks (insert works fine). I dont have time to solve them for now (maybe this is C5 bugs - i saw some of my issues in "bug reports").

Inside:
C:\wamp\www\concrete5_test_8\concrete\config
'version'           => '5.7.5.6',
    'version_installed' => '5.7.5.6',
    'version_db' => '20151221000000', // the key of the latest database migration

Inside update
C:\wamp\www\concrete5_test_8\application\config\update.php
- i comment this lines:
<?php
/* return array(
    '0' => 1,
    'core' => 'concrete5.7.5.7',
);
 */

"THE PROBLEM" its still 5.7.5.7:
system/environment/info:
# concrete5 Version
Core Version - 5.7.5.6
Version Installed - 5.7.5.7
Database Version - 20151221000000

Hi siton,

When you say that you upgraded manually, did you follow the steps described in this tutorial:
"How to manually upgrade concrete5 (5.7)"
http://documentation.concrete5.org/tutorials/how-to-manually-upgrad...

Have you tried forcing the upgrade described here:

I do the steps - but When i run the script
/index.php/ccm/system/upgrade?force=1

I get this error:
An exception occurred while executing 'truncate table CollectionVersionBlocksOutputCache': SQLSTATE[42S02]: Base table or view not found: 1146 La table 'my_site_8.collectionversionblocksoutputcache' n'existe pas

In first i upgrade by putting the C5 new version insdie update folder (this tut) - now you show me another approach -
