How to Apply the YM Multi Messenger Patch — Step‑by‑Step Tutorial

Before you start

• Backup: Save any important chats, settings, and configuration files from YM Multi Messenger.
• Source: Download the patch only from the official project page or a trusted mirror.
• Compatibility: Ensure the patch version matches your YM Multi Messenger version and your OS.

Step 1 — Download the patch

1. Open the official project page or trusted mirror.
2. Download the patch file (usually named like ym-multi-messenger-patch-vX.Y.zip or .exe).

Step 2 — Verify the file

1. Check the file size and filename against the site’s listing.
2. If a checksum (MD5/SHA256) is provided, verify it:

bash
Copy CodeCopied
sha256sum ym-multi-messenger-patch-vX.Y.zip 

Step 3 — Prepare the application

1. Close YM Multi Messenger fully (check system tray).
2. If the app runs as a service, stop the service.
3. Note any custom plugins or themes; copy them aside if needed.

Step 4 — Apply the patch

Option A — Installer (.exe):

1. Run the installer as Administrator (Windows) or with appropriate privileges.
2. Follow on-screen prompts, accepting defaults unless you need custom paths.
3. Restart the app after installation.

Option B — Manual patch (.zip or diff):

1. Extract the archive to a temporary folder.
2. Follow included README for exact file replacements. Typically:
   • Replace binary/executable files in the app folder.
   • Merge configuration or plugin folders as instructed.
3. Preserve file permissions when copying (use sudo or Administrator as needed).

Step 5 — Post-patch checks

1. Start YM Multi Messenger.
2. Verify version number in About or Settings matches the patch.
3. Test core functions: login, sending messages, contacts list, plugins.

Step 6 — Troubleshooting

• If the app won’t start: restore from backup, check logs for errors, reinstall previous version.
• If plugins or themes break: restore saved copies or reinstall compatible versions.
• If permissions errors occur: ensure files have correct ownership and execute permissions.

Rollback (if needed)

1. Restore the backup files you created before patching.
2. If you used a system restore point or package manager, roll back using that tool.

Quick safety tips

• Patch only from trusted sources.
• Keep a full backup before making changes.
