today I tried to update again with custom firmware (Main, Video and DSP) (M:N076 7B11 and V:N060 A6C7 and D:05.13r4 047E)
but not displays "Update success" at the end of the update process but it shows me Write NG!
I closed the amplifier and opened it again and they all seem to work normally
here some photos my question is:to try again with custom firmware yes or no.
thank you very much
The three checksums are correct for the custom firmware with the larger volume display. I just checked mine and I have the same values as you (the one that was modified is for the Main processor, and the new checksum should be 3ADC, which you have).
And since you clearly have the larger volume display and "HELLO" on startup, you are running the custom firmware.
I can't explain why you got "Write NG!" instead of "Update Success". Normally this means the calculated checksum didn't match the expected value, but that doesn't seem to be the case here.
I think you should be OK, but if you want to try again to see if you can get "Update Success", I would suggest you burn the CD again just in case that's where the problem is.
