esantosbravo 0 Report post Posted May 15, 2015 In my case, the printer goes into recovery mode also. I used 2 keys and the downgrade not worked yet. Via USB, all firmware files were transfered to the printer and after firmware upgrade a message is shown: ROM IS NOT WRITABLE. After this message and executing a reboot ( turn off - turn on ), the XP411 goes to Recovery Mode. I sent an email to John - Admin but he didn't replied yet. I did an upload a video to youtube to share the problem with others users and try to solve. This is the YouTube link: Share this post Link to post Share on other sites
