There may be several causes for this, including the following:
- The MPE+ Velocitor may take several minutes to determine the correct boot loader.
- Some chipsets require the mobile device's power button to be pressed before it can transmit data. If it seems to stall at a particular boot loader, release the hold the device's power button to force it to advance to the next boot loader.
- The MPE+ Velocitor has stopped functioning. Unplug then reattach the MPE+ Velocitor from both the PC and the mobile device, then click "Reset" in the wizard.
