I have trouble with upgrade the HDMI FW by using RS232 port.
My AVR is 875.
I was successfully finished procedure to upgrade the Main FW by using RS232 port.
I had before update:
Main: 87 1.02/07625A
DSP 1st: SR8051 07601A
DSP 2nd: SR8052 07518A
DSP 3rd: SR8053 07518A
Successfully applied the "Main Update 1.04" and "Main Update 1.08".
Now I have a trouble with applying HDMI update to v1.02.
I use this update: TX-SR875 HDMI v1.02\HDMIUpdater805_08528A
On the AVR display: Search F/W
And nothing happens. AVR working correctly when I replug the power cord.
I tried several times, each is the same effect.
Here is a screenshot how it looks like after pressing "Video Update":
I wonder why the button layout is different from screenshots in the documentation.
Can anyone provide a link to the current HDMI firmware version to TX-SR875?
