HELP AFTER UPGRADING TO 16756 IN RGH... IT BOOTS UP TO THE XBOX LOGO THEN IT SHUTSDOWN!

forget it i fixed it please ignore this topic n thank you

 

how did you fix it any tutorial?

 

You can just flash your old nand you was originally on
& restart the process of updating your dash

If no screen comes up even in xell just put your old nand on a usb, put the usb in the Jtag/Rgh, then turn on the Jtag/Rgh by using the eject button.
Just give it a few minutes to make sure it updated and restart your console as you usually would.

 

yes! that great will try it now!
