Hello People,

After the HDMI stopped working on my Marantz NR1504, someone changed the memory on board successfully. He could not update the firmware after it. He tried to contact the marantz support but seems the firmware is not available to be downloaded anymore.

Is there any chance someone has downloaded the firmware for NR1504 previously and still have a copy?

Regards
Ankur

No, it is purchased by the person who fixed it, new. He told that the update fails as the chip do not have requited firmware.

Basically you need to first load the boot loader on this blank chip so that you can load flash the firmware. Only service center will have the necessary programmer to flush the chip with boot loader.
 
Purchase the Audiolab 6000A Integrated Amplifier at a special offer price.
