Installing Custom FIrmware on MF279 LTE router

[PRtronics]

Hello.

I have an MF279 router that currently connects through AT&T. It's an unlocked router so I'm interested in using it with T-Mobile too. Sadly, the plan caps the speed to 3G since it detects the usage as a non-mobile device. I can bypass this changing the TTL with an external router, simple. But I want to do this on the main router since I want to use my laptop with it whenever I'm traveling.

I've tried using a third party (Fiverr) to get a custom firmare installed on it but they concluded that it's impossible to do so. Specially that I want to make it user friendly in case I want to share it with other people.


Does anyone know if it's actually impossible? I assumed it was close to it since AT&T owns the router's patents and they don't like people messing with their devices.


Suggestions?

The first thing to check is if the MF279 is listed in one the supported OpenWRT devices.

The person I hired through Fiverr apparently made the firmware using Merlin (if my memory serves me well) because it was a better firmware for it. The problem was installing it because there is no way to install it on the router since AT&T apparently locked it.

I believe this is the page to check for that: https://openwrt.org/toh/zte/start

I don't see it listed.

I'm not even sure if that is the list of supported devices or just a list of all ZTE devices that they've linked to for informational purposes. There is another list that has even fewer ZTE devices in it: https://openwrt.org/toh/start

You are a godsend. I'll send it to my guy that's working on installing a firmware. Thank you gsmantenna <3

Considering this page has more experience. I was wondering if there's devs that can create the firmware too, and make it user friendly. Obviously I don't expect it to be free.

If anyone is interested, let me know.
