Install Nougat OTA on AT&T Samsung Galaxy S6 Edge Plus G928AUCU4EQC6 firmware

The AT&T variants of many Samsung devices including the Galaxy S7, S7 Edge, Note 5, Galaxy S6 (Edge) are already running the latest Android 7.0 Nougat update. OTA update zip files are very rare among Samsung Galaxy devices as the phones are mostly updated via full stock firmware files with .tar extensions. However, the AT&T variants of Samsung Galaxy range mostly receive an OTA update. AT&T Samsung Galaxy S6 Edge users have been able to capture the Nougat OTA files with a newer March Security Patch Level. The Nougat OTA comes with a newer firmware version G928AUCU4EQC6.

The OTA have been captured from the official AT&T servers. Their servers are accessible to only the users on the AT&T network. So the users who are not on their networks won’t receive the OTA and won’t be able to update to Nougat. However, with the mirrors listed below, users can manually update their phones. Meaning, users with the same model number and living outside the US or carrier unlocked phones can make use of the OTA files to upgrade.

Being an Android device, the OTA updates can be flashed onto the device via a couple of methods including ADB sideload, or stock recovery. Simply download the incremental OTA for your device and install it rebooting into stock recovery.
