Note: At present the pop-up warning message has nothing to do with SRM version 1.3 because we are going to install SRM version 1.2.5-8227-1 and not SRM version 1.3 – This message that appears to us today is a clear intention of the imminent launch of SRM 1.3

After you click Yes on STEP 3 a new pop up window will appear with the following message: The system cannot be shut down during the update. Do you want to continue? Click Yes. Wait approximatively 5-10 minutes for the update to be completed. Follow the instructions in the image below.
