I ordered two X2Pros a few days ago, and Im experiencing problems too. I double checked all my connections with a multimeter, and everything came out okay. With one chip, I enable it (non-flashed) and it reboots 3 times, then flashes red and green so Im assuming my d0 point is correct because of this. However, this chip cannot be detected with the X2BM, and therefore cannot be flashed. With the second chip, I re-did all the wiring and used the second FCC cable and external programmer. X2BM detects this fine, writes to 100%, then fails on verification. With DIP #4 on, it doesnt go to the reboots/flashing red and green. Ive switched out the chips, and they have the same behavior each time the first chip will boot, but not flash the second chip will flash, but not boot. Ive tried multiple computers with X2BM to flash. Im pretty convinced that both of these chips are bad
So now what? I've e-mailed extreme mod's support -- hoping to get some information soon on returning them to be tested.
