Can the Lumia 920 base firmware be flashed into an AT&T unlocked branded 920?

Is it possible to do what the title says and what would be the benefit to run a non-AT&T firmware? My phone was unlocked by AT&T when they provided a code after I asked them for it.

Yes you can..Iam running Indian firmware on my ATT lumia 920
you need to flash it with pre portico rogers firmware first and then flash with firmware of ur wish.

Thanks for the link! Are you using the AT&T sim card at the moment and do you have the unlimited data plan? If you do, can you tether?

No I'm in India right now. It's an unlocked phone..internet tethering is working after flashing with Indian ROM

Just a FYI, When I had a trip to the Philippines, I used my att branded att-rom NL920 with a Philippine sim card after unlocking. I was able to tether using the a Philippine network. I did not flash my rom.

If that's the case then that means tethering is associated to the sim card.

when u did this are u now seeing the highest connection option in celluar settings where u can select 2g,3g or 4g???

My highest connection is 4G now where before it used to be LTE and the speedtest results were much faster with LTE. If you do flash it you can't go back to AT&T's firmware as I found out. So you're stuck with what you have for now until someone finds some other way to put the at&t firmware back.

4g and LTE are the same thing from what I understand, it's just a marketing thing.

Also, my phone says "4g" but it reaches the same stupid high "LTE" speeds it did on stock ATT rom.

Maybe you're right. I just ran a speedtest and I'm getting close to 20 mbps down and close 10 mbps up at home.
