WF-C5890 / WF-C5810 - DATA FILE IS NOT FOUND

[Jeff Garcia 0]

Hello, everyone.

Unfortunately it looks like Epson played a trick on us.
We are experiencing firmware upload issues on newer models of WF-C5890 and WF-C5810 printers.
Even turning on the printer in service mode, at the end of the firmware transfer process, the following error message is displayed on the screen: DATA FILE IS NOT FOUND. 
We've tried transferring the firmware in normal mode and in firmware mode, and neither is working.

Are you already aware of this issue?
We have at least 6 cases where it is not possible to transfer the firmware due to this issue.

Is there any solution for this?

Thanks in advance for your attention.

Hope you can help us. 

Att.

Jefferson.

Good day.

Please, provide more information about the issue, exact model and exact name of the firmware you are uploading as well as detailed descripion of how you are entering the service mode, if possible provide a screenshot of the printer's screen in the service mode at the beginning before you start the upload process.
