Ich würde an deiner Stelle erst mal auf C gehen. Hat mehr Leistung. Dann auf D und anschließend auf D1. Immer die Reihenfolge einhalten. Zu deiner Frage, steht auf der ersten Seite. Hier noch mal:
Changelog:
Besides of themes, icons for stock launcher and added NL, HU, BG languages;
-updated modem from Marshmallow 6. For me, personally, modem from 511C was very unstable.
-CDA: fix indian region, fixed model, added languages to 100A0 profile;
-Sound fix: incoming call volume, other volume levels, patched audio effects; used original m810 sound calibrations library's.
-init.d support.
-Fix CPU lags: Infocus cpu governor doesn't work good on our phone. Lot of gamers claim on lags in games such asphalt and others. I have found made by xda member a better governor, that has perfect balance in performance, battery usage and temperature; thermal engine retuned.
-camera patch. Patched some files to use m812 enchantments as I did on marshmallow 6. Dunno if you find any changes.
Patch 5.1.1D1
Neues Modem und geänderte CDA.
