hey, needmsome expertise please. been doing this for a long while now, and wanted to update my chip from an x2.6 to a X3, so all i did was remove my x2.6 and put in the X3(yes it's turned the right way) hooked up the power/eject assably and the wires and pins are the same as the x2.6 only the x3 is turned the other way. i got the flash bios screen and i know how to make bios discs, so i made a couple just in case of a bad burn! after the flash is shut down, and when i powered up, i get a blank scren with no A/V at all. MS dash boots fine, and if i put back in my x2.6 that works fine. so i put in the x3 again, and again, boot from the backup using the power/eject trick, and flash once again, with a newly made iso bios cd. And guess what? yep! blank and no A/V everytime i try to flash the same sh*&t happens. i have a 1.2-1.5 xbox and my d0 wire is installed from the top, i went to cllege for soldering/computer repair, so i do know that it is not my perfct soldering job, plus my x2.6 works everytime like a charm. i run evox, build 3935, 250gbhd, and my setup is perfect, besides the ten minute swap turned into a all day and night thing! i can't figure this out, so i has to be a X3 problem or you know what to do. thanx and help me please.
