When i attempted that major fail was the result. The firmware installation halted and froze. All i have is a black screen on the 3790t. Super dissapointed.
Logo gone when 37xx go to 34xx because of different size of logo.
If you run on 34xx firmware then you need 34xx Logo to be flashed not 37xx logo.bin
The black screen is not the sign of dead 37xx. If you see the light appear on screen after you press power button so it means you can access preboot mode to go back to 37xx firmware.
