The APK I used was for the OnePlus One and had a MD5 of 2fd1a3e8f5a6ef44d1f14752b4caa5c9.
I installed another APK, coming from this ROM, and everything fixed itself (the MD5 was different: 3f465ccbfe8566479f863582671575c2)



The two APK had the same version number (1.0) and OnePlus One's was 1.97 MB while the working one was 1.9 MB o_0
