I recently replaced my Ubiquiti AirCube-AC because I missed the sheer configurability of Tomato. It's been years since I used a router with this installed, but Ubiquiti's UI for the AirCube is fairly hobbled as it is a fairly new product, and as it is meant to be a "set it and forget it" device used more commonly by WISPs in rural areas (among other use cases).
After some light web research I discovered that Tomato by Shibby, a popular fork of the Tomato firmware, had been discontinued, and that he was now advocating FreshTomato, so after a quick donation to thank him for his work, I downloaded the appropriate build of FreshTomato for my router.
My first attempt was simply using the firmware update tool in the router interface, which failed spectacularly1. Some more light web research revealed that this was no longer an allowed way to upload a custom firmware.
So the appropriate steps follow, though proceed knowing that you are voluntarily voiding the warranty on the router.
I have attempted these steps on the following routers:
.trxfile to a temporary folder (in my case,
tftpvia the package manager of your choice (e.g.
apt install tftp)
tftpto start tftp. These steps were taken from Chris Hardie's guide to recovering ASUS router firmware
tftp> put freshtomato.trx(use the actual filename here)

From here, you should have a fully functioning ASUS router running FreshTomato.
1 Can you blame me? The first router I ever loaded Tomato on was the inimitable Linksys WRT54GL. Just gaze at the sheer beauty of this device... from its nauseating purple plastic exterior to its knobby little antennae. Good times.
