Hey All,Here's how to update to the latest version of Marshmallow, finally released. I rehosted everything on Google Drive in case AT&T pulls the files. This is the PD6 version of the firmware.I was rooted running a custom rom on 5.0.2. If you're running the previous latest build (OJ9), you can start the instructions at step 7.1. This will wipe your phone, so be sure to backup before doing any of this2. Download Odin and the 5.1.1 OJ9 firmware files (4 of them) from Google Drive3. Flash in Odin by clicking all 4 buttons (AP, CSC, etc) and matching them to the 4 files from the OJ9 firmware4. Click start6. Once your phone reboots and you verify you're running OJ9, you can flash the 6.0.1 update through ADB7. Make sure you’re running the latest version of ADB (windows package included in the folder worked great for me on Windows 10)8. The file named “SS-G925AUCU3BOJ9-to-U3CPD6-UP” is the 6.0.1 update, download it and rename it to “ota.zip” and place it wherever ADB is installed9. Power it off10. Once it’s off, hold the power, home, and volume UP buttons until it says installing update, this is entering recovery mode11. Once the menu is up, use the volume buttons to select install update from ADB12. Type “adb devices” to confirm your device is ready, then “adb sideload ota.zip”13. It’ll take quite some time, but eventually your phone will reboot and you’ll be running the official PD6 version of the AT&T 6.0.1 update for the S6 edge. Enjoy!EDIT: If you're having problems with ADB reading the 6.0.1 update, try first launching ADB from wherever it is installed (C:\Program Files (x86)\Minimal ADB and Fastboot\ for me), type "adb kill-server" then "adb start-server," then "adb devices" to confirm you see your device (it should say sideload beside it if it is ready for the update). Then, type "adb sideload " and simply DRAG the ota.zip file from wherever you downloaded it to the CMD window. It should complete the command so that it is "adb sideload ota.zip". NOW press enter, and give it half an hour to complete or so. Good luck!! Special thanks to XDA user gmccowan1 for the tip.Have fun!
