New HTC M8 has no LTE
I have a new AT&T branded HTC M8 with Android 4.4.2 with unlocked bootloader, which doesn't get LTE. It was working for 3 days, then it switched to 3G/HSPA+ only. When I use a nano SIM from the Iphone5s on my account, LTE works fine on the M8.
Cannot switch network mode settings to "LTE auto", the device will revert back to "WCDMA auto" no matter what. This AT&T M8 phone clearly works on LTE. What is up this ? Please advise.

You only unlocked the bootloader, or did you apply any mods?
Since it works with another nanoSIM, this would suggest that the issue is either the nanoSIM, or possibly how your account is provisioned. Go to an AT&T store, and they can probably sort out either one.
