I'm having issues trying to read the nand off my xbox with the Matrix NAND Flasher. Whenever I try to read the nand I get an the error message "Could not detect flash controller! Can not continue". I've checked the soldering multiple times and have even resoldered a few times just to be sure. No issues when trying continuity checks with the multimeter. I've plugged in the power to the xbox, plugged in the ROL, didn't turn the xbox on and have tried reading using nandpro 2.0e. The drivers are all installed and I can see it under Device Manager. Xbox still turns on and boots up to the dashboard with no issues. Not sure where to go from here.

Any help would be much appreciated.
Here are some pics of the soldering job:
