an update :
i didn't try de-solder CPU_RST to front side yet ... but tried different routing, and as Mr C mentioned to remove the loop (green wire), all that and same result !!
but i notice some strange thing ! ... when i tried to access Xell by the eject button it didn't work! the console as i said is glitching fine with good boot time, but xell gives me a (scattering screen-digital noise) i don't know how to describe it !! lol ... could it be bad flash?
