Failed Firmware downgrade.

Recommended Posts

Hi, yesterday I bought a key to downgrade my printer's firmware, epson wf 2510.
unfortunately the firmware downgrade was not successful.
I resurrected the printer from the recovery state with an official update, but unfortunately the downgrade key is no longer valid.
it can be reactivated?, I would like to retry the firmware downgrade.
thank you.

my order number is:
# 16529662

Thanks, I tried the downgrade again, but nothing to do.
Is there any other solution? I can't read non-genuine cartridges with the firmware installed.
