Tired and obviously confused today, so I updated the firmware which I never do. To recover, I used the MAC dmg file from Paul Muir above. Saved it to a to new folder somewhere and extracted it (click on dmg file). Then I used Finder to go to Applications, Epson Software, Epson Firmware Updater. Create a "backup" folder and copied the old software to that. Copied the newly extracted dmg files from my backup folder (19_license.txt, Epson Firmware Updater.app and FWCH67TL.efu) to the WF-7840 Series folder.[br]

Then put the printer into recovery mode. Turn off printer. Hold 4, 7 and Job Status button on right side of printer, then power on. It came up with a black screen similar to DOS. I then ran the updater using the files I had placed in the WF-7840 Series folder (navigate to folder and click to run on Epson Firmware Updater.app. Follow app steps. It took some time and you need to not turn off the printer. The power button will blink occasionally while waiting. Wait until it turns off by itself. Took about 10 minutes for me. Then I just powered it on, got the unsupported cartridge error. Opened the top and removed and reseated my third party cartridges and that worked for me.[br]

I only wrote this because I could not find a MAC specific solution. I am on Sonoma 14.2.1 and had to read a lot of articles and posts to piece this together for MAC. [br]

But large thanks to Paul for including a MAC file.
