i just bought a modded xbox not sure what chip it has but it has avaqlaunch and when i got it home it started flashing red and green. worked till i got it home.
It seems like some Dash's change the colors of the led light just for aesthetic touches. But are you saying that it doesn't work at all? Like, it won't load games or anything else?
If your XBox FRAGs then it's probably a bad solder point on the header pin or the D0. Check the soldering job. If two are touching or one doesn't look very full you may need to add a bit. I had the same problem when I installed my Xecuter but it was a quick fix.
I took it apart and the chip is solderless but still not sure what chip it is. it doesn't boot up and I can't figure it ouy.
well if it isnt booting correctly, then you really need to take it back to the place you bought it from, and have them replace/fix it. Because FRAGing is almost alway the sign of a botched soldering job.
the chip is solderless and appears to be instaled correctly i now got the message that my xbox needs repair. I still can't identify the chip but there is an two leds on it one green and one yellow. now when i turn it on it comes right on and starts flashing green and red and gives me the xbox needs service message.
If its solderless did you try taking it off the adapter? Try taking it off and booting. If it boots properly without the chip the adapter isnt seated properly. Could have gotten a bang on the way home. Dont unscrew the adapter for the mo just take the chip off the adapter! Use this to find out what chip: http://www.xbox-scene.com/modchips4_table.htm
Also, you say you have Avalaunch on there, the reason your box is FRAG may be a bad BIOS flash on the chip. If you have a backup BIOS bank boot from it and reflash the primaries.
I have no idea how to do that.I can't even discern which chip is in there. i looked at it and can't find one on the internet that looks like it.
