BTW: in the EU there is movement towards mandating ISPs allow BYOD, including fibre ONTs.
It is my understanding that ISPs have management software that watches all the ONT activities. They will mark a rogue ONT as an “alien” and blacklist it.
not to mention that its probably jail time in the USA if they want to go after you. All they have to do is to show a judge that you "hacked" their device with some hacker "jtags" to extract the very well protected passwords.
Being forced to used an ISPs fiber router can be frustrating, I hope we can get regulations to force BYO
It's an interesting site but where's the 0xbeef? OK it explains how to telnet into some units but then what? How do I get the free HBO ser?
The point is to be able to use your own hardware, a fiber equivalent of buying your own cable modem and router.
I'm only just digging into the site, but some ONT pages (ex [1]) have information on how to set low-level parameters (MAC, various equipment IDs, etc). Probably won't get you free HBO, more likely to get your ONT banned at your ISP, but maybe you'll get free internet before that.

This isn't about getting free internet, no competent ISP will let the link come up without a serial number registered with the port. This is about bypassing the awful gateway hardware many fiber ISPs mandate.
There are also folks that want to overwrite the MAC, serial, etc to clone their ISPs ONT - allowing them to use a different GPON/XGSPON ONT/SFP(+) module [0].
