Hello, I’m Nathan, and I’ll be assisting you today. My livelihood depends on your positive feedback, so your satisfaction is my highest priority.

Sorry to hear you’re having trouble.

What is the complete model number?

Customer: replied 1 year ago.
Hi no one has helped me but charged me on my card.
Expert:  Nathan replied 1 year ago.

Per the terms you agreed to you, you are charged the full amount upon corresponding with an expert.
You've posted no details of your question, and I've asked you for some additional information.
I cannot help you until you provide the requested information.

I need to know the complete model number of your receiver.

Is it actually powering up and operating normally but it just won't update again?
Or will it not boot up past the retry update screen?

Customer: replied 1 year ago.
Sorry to say I had mentioned that I cannot work late night I had to sleep at that time, and could only work next day, still you charged me, if ok we can discuss now
Customer: replied 1 year ago.
AVR X1100W

Sorry, none of those comments came through, only that you powered off during an update.

Unfortunately with denon receivers there are really no firmware recovery options.
If an update is interrupted, it can "brick" the receiver, causing permanent damage. Ultimately, repairs will probably be required.

There are a few steps we can try, but I need you to please answer all of the questions I asked:

Is it actually powering up and operating normally but it just won't update again?
Or will it not boot up past the retry update screen?

Customer: replied 1 year ago.
It is powering up but not working normally, message I get is retry update and then after sometime it shows normal Cab/Sat, if I restart again same way
Expert:  Nathan replied 1 year ago.

Okay,after it gets to the point of normal cable/sat, are you getting audio/video?
Can you get into the menu at that time?

Customer: replied 1 year ago.
No, no audio video and does not show anything on TV
Expert:  Nathan replied 1 year ago.

Okay then in that situation your powering off has corrupted the firmware.

The only thing we can try here is a microprocessor reset,

Expert:  Nathan replied 1 year ago.

Starting from power off,

press and hold the tuner preset + and - buttons on the front panel

keep holding while powering back on, until display starts flashing

then try to go into the setup menu and run the update process again

Let me know the results.

Customer: replied 1 year ago.
Did the same , still the same issue
Expert:  Nathan replied 1 year ago.

Thank you for confirming.

Unfortunately, that is the only thing you can do yourself here. There is no manual or usb based recovery option for denons.

The receiver would have to go in for repairs at this point, as the interruption of the update corrupts the firmware and the only way to recover that will be to replace the main board in the unit. Denon typically will not honor any warranty coverage for this, as they consider it a user error.

It won't hurt to try filing a warranty claim, however if they won't cover it, you are probably better off replacing the receiver. Repairs will run you about $450, and you can replace it with a brand new unit (or even the newer model) for less:

Please note:

I am an independent technician and I've spent my personal time, unpaid, in a good faith effort to assist with the question for which you solicited my services. I am only paid for my efforts when customers such as yourself leave positive feedback for my work. Again I apologize there is not a better outcome here, though this is really beyond either of our control. I do hope you’ll consider leaving a positive rating for me, rather than “shoot the messenger”, so that I may get credit for my time spent in good faith to answer your question accurately.
