It sounded like you destroyed your Xbox 360 due to bad soldering or a soldering mishap (splashed solder??)

if it does not turn on at all, that means the xbox cannot load the SMC code from the NAND. this can have several reasons, maybe your cygnos NAND is empty?

if you get RROD, thats most likely not caused by the cygnos installation, only if you shorted something. otherwise the console simply doesnt boot at all. try to look at all places with a magnifying glass.

we recommend to solder some fresh solder onto the pads on the bottom side of the mainboard before you solder the cygnos360 onto it, because that solder MS uses is pretty much crap...
