Confirmed working and running S.P ok on ...
Huawei P1 with 4.1.2 Cyanogenmod 10 (Ext Sd System folder) libgarminos = external_sd.zip
Huawei G510 with 4.1.2 Cyanogenmod 10 (Ext Sd System folder) libgarminos = external_sd.zip
Huawei G526 with Stock 4.1.2 Emotion UI (Ext Sd System folder) libgarminos -sdcard1.so needs to be replaced every reboot.

The G510 is the only phone out of the 3 Huawei Ive tried that plays POI Speed camera alerts and keeps the volume high after reboot.
