Recently my TS401 wouldn't allow me to access functions because of the message " Are you sure to delete the TPMS data (Y/N)?" even when pressing Y or N, it wouldnt go away. So I started by updating software, succesfully did to version 5.59, but now if I unplug the USB it will always turn on in Update mode, if I plug the USB it turns on in the main menu but each time I select any of the menu options it shows again "Are you sure to delete the TPMS data (Y/N)?"

 Hi, I tried several times your method, but it still starts in PROGRAM MODE, however if I start it with USB it does seem to power on right, but as soon as I start going through the menu the "ARE YOU SURE TO DELETE DATA" appears and seem to block functions.
