Use PhoenixUSBPro when the projector does not boot normally and standard USB recovery is not possible.

• USB-A to USB-A data cable
• Magcubic HY300 Pro H726
• Projector power adapter
• update.img

⚠️ Important

• Use only the included update.img for the target H726 hardware.
• Do not modify, repack, or rename the firmware unless the procedure explicitly requires it.
• Do not disconnect power or USB while firmware is being written.
• Incorrect firmware can permanently brick the projector.
• Always double-check the firmware filename, checksum, hardware version, and flashing instructions before proceeding.
