Attached are modified factory roms that will flash an at&t or t-mobile phone to an unlocked phone. This means no more bloatware and in my case much better handoff between the lte bands.
These images reuse the carrier bootloader (I'm working on it) but everything else from the radio to the rom is from the unlocked priv.

Directions: Unzip files. Hold power and volume down until phone reboots to fastboot. Launch flashall.bat. Follow instructions. This WILL delete your data so have a backup or don't I'm your boss. Wait. Done.
As usual I am not responsible for you bricking your phone. That being said even if the wrong file is flashed the phone gets stuck at the fastboot screen where you can flash the right file.
