Error: "Burn Failed: Uboot mismatch"

Cause: Your firmware is for a different RAM type (DDR3 vs DDR4) or NAND size. You need a PCB-specific build.

The Flashing Process

1. Install HiTool on your PC. Do not launch it yet.
2. Install the device driver: Inside the HiTool folder, run Driver/install.bat as Administrator.
3. Prepare your STB: Unplug the power. Do NOT connect the USB yet.
4. Configure HiTool:
   • Launch HiTool.
   • Select Hi3798MV100 from the chipset dropdown.
   • Go to Options → Configure → USB Port.
   • Select your PC’s USB port.
5. Load the firmware:
   • Click the "Burn" tab.
   • Click "Browse" and select your .xml file.
   • Check "Burn eMMC" or "Burn NAND" (depending on your box).
   • Ensure all partition files (fastboot, boot, system, recovery) are located in the directory listed.
6. The Magic Step (Boot Download):
   • Click "Burn".
   • Now connect the USB cable to your PC and the OTG port on the STB.
   • Immediately connect the power adapter.
7. Watch the progress: HiTool will detect the device. The blue progress bar will move to 100%. This takes 3-5 minutes.
8. Disconnect when "Burn Success" appears. Power off, disconnect USB, reconnect power. The first boot takes up to 5 minutes.
