However, when the process completed, the printer still displayed version 10.44.FA25JA, indicating that the downgrade failed. Please help me downgrade the firmware for Epson 7710, thanks.</p><p></p><h3>Solution</h3><p>1. Download and extract the Firmware Version - FA99Z9 - <a href="http://chiplesssolutions.com/download/WF7710_FWG535TL_FA99Z9.zip" target="_blank">http://chiplesssolutions.com/download/WF7710_FWG535TL_FA99Z9.zip</a>.</p><p>2. Upload the firmware to the printer in normal mode, without putting the printer in Program Update mode.</p><p>3. The uploading process will get stuck at 70-80%, which is normal.</p><p>4. Open task manager and stop the updater process.</p><p>5. The printer will blink for about 5-15 minutes, then power off.</p><p>6. Power on the printer again - the chipless firmware is now installed on your printer.</p><p></p><h4>Successful Outcome</h4><p>Ok, thanks, it worked!</p><p></p><h3>Additional Inquiries</h3><p>- Do you have the Activation Key for Epson 7210?
