John_Admin 388 Report post Posted February 2, 2020 Please download firmware here - https://chiplesssolutions.com/download/WFC5710_FWG239TL_ZZ99Z9.zip Upload firmware to printer in normal mode - dont put printer in Program Update mode. The uploading process will stuck at 70-80% - it is ok! Printer will blink for about 5-15 minutes - then will power OFF. Now power on the printer and run License utility and use your Activation Key you have used first time. Please reply about results. Share this post Link to post Share on other sites
