WF-6090 - Firmware Downgrade Not Working

Recommended Posts

I am unable to downgrade the firmware of the epson wf-6090. I did all the steps... I finished the processes, put the printer in IPLK service mode - IPL Updete. When I give the command to downgrade the firmware, the program stops responding. If I put the printer in normal mode, the process starts, but does not complete and I lose the key. I have already paid for 3 keys...

Firmware ver: DG03K7 date: 03/07/2020 to DG15G4 15/042/016...
