Hi, I'm afraid that I can't provide any firmware to you since Zyxel provides NR5103 firmwares only to network providers, and it's network provider's decision to roll out firmware to end users. If you can provide the serial number, I can try to find out which network provider you may contact and see if they're willing to…
