I installed the CU Updates of the August, then run the command of Upgrade-SPFarm command after that my schema version changed, so I can't deploy any solutions in visual studio. I need to rollback the process.

  • What you mean by you can't deploy any solutions? Are you able to access the sites? Aug 30, 2016 at 13:14

There is no safe rollback path. That is reason we should always backup before applying major changes to the system.

  • I have Farm Backup,How long its takes to Restore

  • did you reset all of your farm servers? did you run the configuration wizard after the upgrade? Aug 30, 2016 at 13:53

You cant roll back a CU as it upgrade not only the File System on the SharePoint Server as well as upgrade the Databases.

Options, you have to troubleshoot the issue what is casuing the issue.

  • Open a Support Ticket with MSFT to solve the problem.
  • Examine the Upgrade logs, ULS logs to find any clue.
  • I would Run the Configuration Wizard on All Servers
  • Still having the issue then try to clear the config cache.

Lastly you can restore from a farm backup, which required a lot of efforts as you have to rebuild your farm.
