my google play services version is : 7.5.73 (1976294-036)
i use gmail (latest) every days and sometimes i use maps (latest) also
i hope this can help
have fun
PS i use this gapps: pa_gapps-modular-nano-4.4.4-20150308-signed.zip
I do not understand.... I just tried again, I completely formatted all the contents of my phone, even the internal memory, then I installed the latest version of the ROM, I installed GMail and I updated the Play Services version 7.5.74 (1997312-036). This time I used the gapps you suggested (jajb gapps) and as usual: "Unfortunately Google Play Services has Stopped".
Why to you it works??!!
