I have a Denon AVR-3808 with firmware update issue.
When I power up, after same seconds I see on display :
Please wait… Update retry
Sub Firm Updating 25min
DSP1 Firm Updating 24 min ...remain forever on display.
I try all that I read on internet:
Power up using Standard and DSP Simulation to reset and after try again to update.
HDMI connections are ok and internet radio is ok.
Browsing internet I found it is possible to update using PC with: “DFW_0019_AVR_AVC3808_(Rev.1.0.12).exe” but I can't find this software on internet.
I have service manual and I verify all voltages on the 1U-3799 DIGITAL P.W.B Unit and there are ok.
I made the diagnose with using STATUS and RETURN:
GUI FPGA CONFIG : A080719A
GUI PRG : 00007621
GUI DAT : 37750020
Please help with any advice.
