John_Admin 390 Report post Posted November 26, 2019 Download and extract this Firmware Version - FA24I5 - https://chiplesssolutions.com/download/chipless/WF7710_FWG535TL_FA24I5_FA99Z9.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! Open task manager and stop updater process. Printer will blink for about 5-15 minutes - then will power OFF. Now power on the printer - chipless firmware is installed now in your printer! Please reply about results. Share this post Link to post Share on other sites
