Nowhere did you say it came with original dumps.(also, I already said you did a bad flash job on it before you did and that was the problem) And since it has been xclamped, you have further shortened it's lifespan. Again. There are tons of people selling working consoles for this much. And your OP says $180+ $20 shipping.
I guess you don't really understand that to repair it, you basically have to reJTAG the thing. List your item for what it is...
Xenon
JTAGable
Xclamped (that will also need repaired)
Banned from XBL
$130 + $20 Shipping
That sums it up... now allow me to retort...
Falcon
HDMI
Virgin system (not modded, not banned)
No XClamp rigged fix
Boots, loads, and plays games perfectly
JTAGable Blade Dash
No errors whatsoever
$100 + $10.70 shipping(US)
Think maybe you should lower your price just maybe. Look up a console (Can't call it a JTAG cause it's not, that all has to be redone) Banned, Errored, and xclamped... Perhaps, if you're lucky... $40
OP: I believe you've just been pwnt...
