USB Firmware Updates – North American Denon AVR units only
Although the firmware update issues seem to be more of a problem with the XX13 models, if you are having difficulty loading the latest firmware to your 4520CI, please PM me after reading and agreeing with the disclaimer noted below and I will provide you with the file to load via USB.
This firmware is for use with North American Denon AVR units only
. Feel free to use it under the condition that it not be forwarded to other individuals and is for your personal use only. It is provided with the understanding that you will “use it at your own risk
” and it comes without any implied warranty from D&M. You agree that D&M will not be held responsible for any damages to your unit resulting from the inappropriate use of this firmware or from updating the unit in an improper way. As this update being provided to you is not supported by D&M, should you have any installation issues, please do not call Denon customer service for support as they will be unable to assist you.
After downloading and unzipping the provided .zip file, you will find a “firmwares” folder and a Word document which provides instructions on how to install the firmware update. The “firmwares” folder must be moved to an “empty” FAT16/FAT32 formatted 2GB (or larger) USB memory stick. Note that should you have any issues with the update, you may have to reset the unit’s microprocessor after doing the update so prior to installing the update, be sure to copy the unit’s on board configuration file to a PC using the Web Control SAVE feature.
