Im not new to moddin just new to moddin slim systems. i was looking a jf tut and it said that slim lite-on cant be writtin to if dashbaord is up to date. is this tru? in order for me to right the fw to the slim lite-on the psb must be unlock by mod chip or alternate method. so on top of the x360usb pro v2 flashin tool i also need another mod chip just to write to slim lite-on.
