Just a heads-up: make sure your router’s firmware version matches the one mentioned in the guide. Mine was on an older build, and the steps still worked, but a friend with a newer locked-down version needed a different unlock code method. Overall, highly recommended for anyone needing to free their ZTE F670L from carrier restrictions. Saved me the cost of buying a new router.
Some fiber networks (like GPON) authenticate via the device’s MAC address rather than the SN. To unlock your ZTE F670L for a new ISP, you need to clone the MAC address of a router approved by that ISP.
