Once the fresh firmware is installed, you face a new problem: BlackBerry World is technically shut down (EOL April 2024). You cannot download apps normally. Here is how to make your Z30 useful again:
| Symptom | Likely Cause | Fix | |----------|--------------|------| | Stuck on boot logo | Corrupt OS or wrong autoloader | Reflash correct STA100 autoloader | | No cellular signal | Radio mismatch | Flash the exact regional autoloader again | | Battery drain after flash | Indexing | Leave on charger for 24 hours; reboot | | Can’t add Google account | No Google Play Services | Use ProtonMail or Outlook via IMAP | | Android apps crash | Runtime 4.3 incompatibility | Use older .apk versions (2016–2018) |
