SXTsq 5 High Power in endless boot loop ?

I tried to connect to an new SXTsq 5 High Power with WINBOX 3.12.
The first time i succeed, but now it seems, the device is in a endless boot loop.
Pushing the reset button or waiting a few minutes without power and reconnect did not help.
Another identical SXTsq 5 High Power can be connected at once by WINBOX 3.12 => my equipment (notebook) is working.

  • How to reset properly (reset procedure) ?
  • How to put the device in as-delivered state (factory settings) again ?
  • How to make a firmwareupdate manually ? The new SXTsq 5 High Power has in comparison to SXT Lite5 no Buzzer and
    no direct access to the pcb to the reset pin. Is it still possible ?

btw. the lables of the SXTsq do have no reasonable size anymore.

thanks for any hints
