old xbox question

hi
i know these r out of date but was using mine for media great stuff
anyway i had mine chipped (DuoX)
but i got a second and thought i would soft mod the chipped one
with one of the auto install disks and move the chip too the second
instead of going through the normal soft mod route
but it messed up during flashing and now the mod chip seems to be
blank/corrupt as xbox wont boot and has error message

my question is what to do now? can the chip b easy reflashed with cromwell
or should i just buy a new mod chip?
can an1 recomed a cheap supplier of xmob or chips
thanks

I would have thought it more likely just files missing from the hard drive rather than the duo-x2. Can you be more specific on the error message ?
What happens if you put the chip on the 2nd un-modded machine ?
If the error message is on the 2nd machine, have you fitted it correctly (1.6 ? bank switch correct ?)
