My Xbox was working properly but I had the older dashboard in my Xbox 360 E jtag. I installed the latest dashboard using Simple 360 Nand Flasher. As it reflashed, it turned the console off and now its not opening.
When I press on the console button the green light pops up and I can also eject the disc tray and the power adapter is also perfectly fine plus the HDMI is fully plugged in and properly working. When I press the xbox start button the green light pops up as usual but it doesn't boot up nor does it make any sound.
I have tried to start it multiple times but it isn't working On the TV it just says No Signal.
