My AT-1 update does not work

If your device does not update, which you can best recognize by the fact that the software version does not change after the update, please proceed as follows:

  • Try one or more other USB sticks. Preferably "old" USB sticks with little memory (e.g. 4GB). 
    Repeat the update attempt several times: Some AT-, especially early serial numbers, recognize USB sticks for the update only after several attempts.
  • Make sure that the update file has not been modified by your operating system or corrupted during the download by downloading a file on another PC and playing it on the USB stick.
