I have unlocked my phone and switched over to AT&T temporarily while away from home because T-Mobile is still stuck on edge where I summer. AT&T has strong lte in my area, yet I'm only able to connect to 4G. I've changed apn settings around and I know the g900t supports all the same bands as g900a... I'm assuming this is a firmware issue, any additional insight is welcome or solution if anyone is in the know.

I'll also gone into service mode by typing *#2263# in the dialer and attempting to manually connect to the AT&T lte bands, I get bars but no data.

You need to have your SIM card provisioned for LTE. You'll have to supply AT&T with an IMEI for an LTE capable device. It doesn't have anything to do with your firmware or device.

Have you tried going into the dialer going *#2263# and manually selecting the LTE band there?

I've called at&t and told them about the provisioning issue and they told me that my phone was properly provisioned in the system for lte. However, they probably just said that so I'd go away haha.

Yeah probably.
That was gOing to be the next thing I would have suggested.
Sounds like something in their network is not allowing it to connect then.
