Important Notice
  • NCK Pro Box requires a hardware box in order for the module setup to work
  • If you've chosen to go with a loader version (no box required) then it might get flagged by your antivirus. You're responsible for choosing to ignore the warning
  • ¬†Avoid restoring a different model's QCN as this could brick the device
  • Its recommended you backup your currenct QCN / EFS before flashing another just in case the newer one makes the device worse
  • Remove the device from Diagnostic (DIAG) mode after this procedure so your Qualcomm device can connect in other modes like MTP

That includes your IMEI, Baseband, WiFi & Bluetooth address, basically anything that involves the phone's radio is managed by the QCN so if this gets corrupted, you'll have a case where your phone can't detect signal or you begin to have NV issues ok?
