How to downgrade firmware

[netgear]

Hi,

is it possible to downgrade from 1.3.0.3 to 1.2.9.0 and how is it done?
I've downloaded the old firmware so far and I know I have to put those files on a usb stick.
Are there some additional things to tkae care of?

Thanks for your help.

You can install any Android 5.1 firmware over any other.

So just download the 1.2.9.0 files, copy them to USB stick and update as normal.
