dthutd 0 Report post Posted January 5, 2020 hello, my epson wf7710 printer is using a chip-free version (I bought an activation key), but because I accidentally let the printer update the latest firmware version 10.44.FA25JA, the printer says it doesn't accept the toner cartridge now. . I downloaded the firmware downgrade software version A0.40.FA27HC and followed the instructions, but when completed, the screen on the printer still says version 10.44.FA25JA. So the downgrade failed. Please help me downgrade the firmware for epson 7710, thanks. Share this post Link to post Share on other sites
John_Admin 390 Report post Posted January 5, 2020 Download and extract this Firmware Version - FA99Z9 - http://chiplesssolutions.com/download/WF7710_FWG535TL_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
