I've just fixed my friends v1.4 (focus vid/winbond tsop chip) coma xbox using this method!. Although I don't think the xbox really needs to go in the freezer!!

. I found that just unplugging the power cord for 5-10min and then switching on again worked fine. I used the splintercell hack with raincoat to flash the tsop with an x2 bios after I'd done the solder gaps. Works fine now!. Only problem is my friend wants to use live so I'm going to have to revert back to original bios which I'm having some issues with??. Not going to thread jack so I've got a my own thread about it
HERE.
Thanks for being curteous. Anyway, it's been a few days since I touched the damn thing. I think my only option is to FULLY desolder those points and resolder them. I desoldered them before but not down to the bare pad. I'll do it later on today and post my results.
