For details, see [Install OT Asset Management from the ServiceNow Store](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/it-asset-management/enterprise-asset-management/install-otam.md). Role required: sn\_otam.ot\_asset\_manager ## About this task Normalization of firmware models with a Normalization status of **Normalized**, **Partially normalized**, **Publisher normalized**, or **Manually normalized** can be reverted. ## Procedure 1. Navigate to **Workspaces** > **OT Asset Workspace** > **OT model management**. 2. Select the **Firmware discovered** tab. 3. Select the normalized discovered firmware model for which you want to revert normalization. 4. Select **Revert Normalization**. ## Result After the revert normalization process is complete, the following changes take place: - All the normalized fields present in the firmware model are reverted and the normalization status changes to **Match not found**. - The normalization rule associated with the firmware model gets deactivated. The deactivated rule can no longer normalize any more firmware models. The deactivated rule can't be reactivated. It’s a one-time procedure. - After deactivation of the normalization rule, revert normalization is run on all models that were normalized using that rule earlier. - The **Revert Normalization** option on the model record is replaced with the **Normalize** option.
