Install ubuntu 18

pedro_caldato

I'm trying to install the ubuntu on it, but I'm getting some troubles:
I'm following the windows tutorial (in http://wiki.t-firefly.com/AIO-3399C/upgrade_firmware.html) and I already did the update firmware step, setting up the ubuntu.18.img, but I didn't understand how to do the "burn partition" step. Here is my problems and questions:
-Where can I find the images of the partition? I already tried to download the Ubuntu(GPT) in your site (http://www.t-firefly.com/doc/download/page/id/54.html#other_148), but the link doesn't work for me.
-In the tutorial of the link "http://wiki.t-firefly.com/AIO-3399C/upgrade_firmware.html", the picture referent to "burn partition" step shows a list of .img relative the partitions that I want to put on the device, but where can I get these .imgs?
-Also, have any tutorial more detailed which explains better what should I do after upgrade the firmware and burn the partitions?


Thanks,
Pedro.
