Posted 26 Oct 2015 Sounds to me that you have a problem with the memory card. Is it a Siemens memory card ? How did you erase the memory card ? You can not format the memory card unless it's done with a Siemens equipment. Share this post Link to post Share on other sites

Posted 26 Oct 2015 Don't really know if you damaged it, but the Siemens format is different than the format written by your PC. You have to buy a new card or format it with a Siemens PG Share this post Link to post Share on other sites
