its advised to stay at lower than 5.5.1 but Im not sure what the difference is, loadiine works fine on 5.5.1 for me
i think you can use WUPInstaller to spoof your firmware, alternatively you could update to 5.5.1 and use Tubehax dns so you dont get slammed with another update and you can still play online with that
That's what I ended up having to do, Thanks.If you are on latest fw why you just dont enable auto dns to update and after that you enable to manual again?
