I also have F5122 with 1302-3039 Rev2. How about it ?
That doesn't matters, i flashed this CDA 1301-2283 Commercial and Journalist. Its Android 6.0

Afterwards you can extract TA-Partition (DRM-Keys) and upgrade to your CDA (Android 7.1.1) again.

The whole process of Downgrade, TA-Extraction and Bootloader Unlock is very well described here. But its unfortunately in German.
