Luc 0 Report post Posted September 22, 2015 I also ran into the issue, that the printer does not recognize my cartridges anymore. After reading and surfing around, I found that Epson blocks 3rd party cartridges with there last firmware update. So I decided to downgrade again, but the printer display always says 100percent done, but WIC-Reset never ends. I tried this several times, no luck. So I decided to install the original firmware once again to be sure, no errors occurred, but the Epson-Firmware-Updater-Tool begins uploading, but stops at 47% and never continues. In several threads, I read that you must not have any Error-messages in the front-panel, so that an Upgrade/Downgrade works. Is this correct, and isn't there a way to pass this, because I don't have any original Epson-cartridges anymore. Regards, Luc Share this post Link to post Share on other sites
John_Admin 388 Report post Posted May 14, 2016 WP4525 firmware downgrade is supported now If printer has any errorrs or you dont have original ink cartridges - You have to make firmware Update in Program Update Mode. First set printer to this mode then upload the Firmware to printer. Share this post Link to post Share on other sites
