What version Xbox? This and this should help.

Chip or TSOP?

If chip, which chip?

Which BIOS did you flash?

Which flashing tool did you use?

It's possible that you flashed a 1.0-1.5 BIOS, which is why your Xbox is no longer working. With an Aladdin chip then the only way to recover from a bad flash is to hotswap it into another Xbox with a chip, then reflash, or to replace the chip as you are doing. Which chip have you ordered?

When you get the new chip make sure you flash it with a 1.6 BIOS. If it's a DuoX2 then you can use x2_5035_v16plus_512k.bin, if it's a 256k chip you'll have to use Evox M8plus_16.bin.

Once it's working you'll be able to hotswap the original chip back and reflash it, so you'll have a spare!

DuoX2 is a good choice. You should be able to just plug it in to the existing pinheader, so long as the installation looks correct. You will need to solder the BT and D0 wires. Have a look at this picture for details of what a DuoX2 installation should look like.

Yes, I mean hotswap as in unplug the chip while the Xbox is running!
