Hi, I have an epson xp-442 printer (black model).
The latest firmware released by Epson prevents the use of non-original cartridges that I have already purchased.
In order not to waste resources, I decided to go back to a previous firmware.
I go into recovery mode, but the problem is that I have not found a suitable firmware on the network.
The xp-442 (black) is identical to the xp-445 (white).
Now I have installed a firmware found on epson australia, the RO20J9 of 2019 but it is too recent.
I installed the Wic Reset which offers the possibility of downgrading to the RO02GC of 2-12-2016 but payment of the keys is required.
I kindly ask if anyone has the original firmware of the xp-442 or a firmware of a compatible model (if it exists).
These would be fine too:
RO12G8 (12.08.2016)
RO10H8 (10.08.2017)
RO21HB (21.11.2017)
RO23I2 (23.02.2018)
RO05IA (05.10.2018)
Thank you all for your attention.
