Hello everyone,

My Denon AVR-X3400H is completely bricked due to corrupted bootloader in the main CPU.

**Technical details:**
- Model: Denon AVR-X3400H
- Main CPU: Renesas R5F564MLJDFC (RX family)
- Problem: No boot, no response - requires JTAG programming

**What I need:**
Original firmware dump (.hex or .bin format) for JTAG programming from a working AVR-X3400H with the same CPU.

If anyone has a working AVR-X3400H and can create a JTAG dump, or has the firmware file, please help!

Thank you in advance!
