Frequently Asked Questions (FAQ) Q1: Can I use a dmhz5350bt firmware update link for any device with that chip? No. The firmware also depends on the display resolution (800x480 vs 1024x600), RAM size (2GB/4GB), and MCU vendor (ST, NXP, or Rockchip). Always verify your exact build number under Settings → About. Q2: Will updating erase my saved radio stations and apps? Yes. A full firmware update wipes all user data. Backup your contacts and app data first using Titanium Backup (if rooted) or a simple file copy. Q3: How often should I update? Only when you experience a bug that affects daily use, or once every 12 months for security patches. If it’s working perfectly, skip the update.
