All I can say is THANK YOU!! Thank you for allowing me to roll back (downgrade) my Epson XP-410 printer\'s firmware with ease!! A couple of clicks, and I was downgraded. This allowed me to use non-oem cartridges that would not work no matter what I tried with current firmware (Epson updated firmware just to battle the use of non-oem cartridges). The money spent will be saved with the very first refill of these refillable cartridges I bought. I was skeptical, but it really was THAT easy! Winning the battle against Epson!! First time I\'ve ever paid for a \"hack\", well worth it!
