| Error | Likely Cause | Solution | |-------|--------------|----------| | | Missing USB drivers | Reinstall Rockchip Driver Assistant v4.7 or newer. Disable driver signature enforcement in Windows. | | “Download IDB fail” | NAND flash corruption | In FactoryTool, check “Upgrade Firmware” instead of “Restore”. If that fails, you need to “EraseFlash” first (advanced). | | Stuck at 87% | Incompatible firmware version | Your device has a different touchscreen driver. Find a firmware with the exact same LCD/Touchscreen code (e.g., YT7260B_JD9366 vs YT7260B_FT6336 ). | yt7260b+update+link
