王朋辉 0 Report post Posted May 22 I purchased a Firmware Key to downgrade my Epson WF-3825 printer firmware. However, the firmware update process took over an hour without success, so I restarted the printer. Afterwards, WIC showed that the firmware had been uploaded, but my printer still has the original firmware version (SI08M4) — the downgrade did not actually take effect. When I tried to use the same key to retry the downgrade, WIC said the key has already been used. The failure was due to a socket connection error during the process, not a successful operation. Could you please issue a replacement key so I can perform the firmware downgrade in Service Mode? Thank you. （This article was translated from Chinese; please excuse any inaccuracies.） Share this post Link to post Share on other sites
