Has anyone tried the "ATT Developer Device" Portico Rom? Does/would it have 3g enabled? I have the Build edition Lumia 920, but it bricked during a reset. Not sure if this would be a good rom to use or not. Thanks!

If anyone in US can confirm I'm all over this

HI,
Yes, I have AT&T branded 920 and I flash it to dev rom due missing features as sms delivery receipt, 2g/3g/4g switch.
I think it is dumb for them to force me to get rid of my unlimited data for this feature considering they throttle you at a certain cap anyway.

Could you please provide where you got the dev rom from and can you enlighten us in regards to whether your device is in fact a developer edition or a plain jane AT&T branded device; thank you!

I downloaded the dev rom through NCS a couple days ago along with a backup of my stock firmware.

So I just tried flashing that version to my black AT&T 920 and it gave me the error Platform ID check fails. Says the FFU file is not meant for this product. Platform ID of image does not match with the platform ID of the device.

Did you flash to any other version prior to going to the dev rom or straight from stock ATT to ATT dev? Perhaps I have to be on an earlier version of the stock ATT rom to do the flash to the current dev rom?

You have to flash to non-portico Rogers rom like RM820_1232.2109.1242.1002 in order to flash your AT&T nokia.
I followed this thread "http://forum.xda-developers.com/showpost.php?p=38325527"

But that will prevent me from going back to the att stock ROM correct. At least it looks that way from the other posts I have read. Wish I could find someone on att that is on the dev ROM and confirm that tethering works coming from a stock branded ROM.

A forum member manage to flash back the AT&T stock rom, but I can find the thread / msg with his steps...there is a app in the store for tethering. It was released last week i think. Did you try installing extra keyboard layout - someone mentioned that this can allows tethering
