This guide explains the root cause of the "License check failed (1006)" or "License check failed (TimeStampError)" pop-up message during Smart Launcher authentication or software update on GDS Smart / KDS 2.0 / GENESIS Smart, and provides step-by-step instructions to resolve it via Automatic Date & Time settings and network verification.

 

Applicable Products & Environment

  • Hyundai: GDS Smart / GDS Smart RND
  • Kia: KDS 2.0
  • Genesis: GENESIS Smart
  • Related Component: Smart Launcher (Installation & Update License Authentication)
 
 

1. Symptoms: Smart Launcher "License check failed (1006 / TimeStampError)"

  • Authentication Blocked in Smart Launcher: When installing, updating, or authenticating your license key in Smart Launcher, an error pop-up appears displaying "License check failed. (1006)" or "License check failed. (TimeStampError)".
  • Installation Cannot Proceed: Even if the installation package download completes, the authentication step fails and prevents the update or installation from finishing.

2. Root Cause & Diagnostic Criteria

Key Root Cause Summary: Error code 1006 (TimeStampError) is NOT caused by a defective license key or a software/server defect. It occurs when the tablet's Date & Time is out of sync with the authentication server (exceeding the ±2-minute tolerance) or when a workshop firewall blocks connection to the authentication server.

 
  • Tablet Date & Time Synchronization Mismatch (Primary Cause): Smart Launcher validates license authentication requests against the server's UTC timestamp. The maximum allowed clock difference is ±2 minutes. If Automatic date and time is turned off on the tablet and the device clock drifts by 2 minutes or more from the server time, authentication fails with error 1006 or TimeStampError.
  • Not a License Key Defect: As long as the license key is entered without typos, enabling Automatic Date & Time allows the exact same license key to authenticate normally.
  • Workshop Network / Firewall Restrictions: If a corporate or dealership Wi-Fi firewall blocks external authentication servers, license verification may also fail with error 1006.
 
Diagnostic Factor Applicable Cause? Notes
Tablet Date & Time Configuration Error Yes (Primary Cause) Fails when tablet clock differs from server time by more than ±2 minutes
Workshop Network / Firewall Block Yes (Secondary Cause) Occurs when restricted Wi-Fi blocks authentication server access
Defective License Key / App Defect No The same license key succeeds once time synchronization is restored

3. Step-by-Step Resolution (Automatic Date & Time · Mobile Hotspot)

Step A: Enable Automatic Date & Time and Automatic Time Zone in Tablet Settings

  1. Open Tablet Settings: Go to Settings on your Android tablet.
    Tablet Settings screen
  2. Open General Management: Scroll down and tap General management.
    General management menu
  3. Select Date and Time: Tap the Date and time menu.
    Date and time menu
  4. Enable Automatic Date and Time: Turn ON both Automatic date and time and Automatic time zone.
    Enable Automatic date and time toggle
 

Step B: Connect to a Mobile Hotspot and Retry Authentication

  1. Switch to Mobile Hotspot (If Workshop Wi-Fi Is Restricted): If the error persists after enabling Automatic Date & Time, connect the tablet to a smartphone mobile hotspot (tethering) or an unrestricted Wi-Fi network to bypass firewall blocks.
  2. Verify License Key & Relaunch Smart Launcher: Close Smart Launcher completely, relaunch it, verify that there are no typos in the license key, and proceed with authentication again.
 

Verification: Once Automatic Date & Time and network connectivity are properly configured, license verification completes immediately with the same license key, allowing software installation and updates to proceed normally.
