In first place, I want to apologize in advance for English mistakes, because I have only a basic knowledge in that language and I'm typing it all at the end of the night, here. So, I'm somewhat oblitered by the sleepless time I spent diagnosing and trying to fix some problems I had while flashing CM11 to my Xperia M device.
Well, due to some mistakes when installing GApps (I didn't want to be all-connected to Google), I have formated and reinstalled the system at least four times. Now, at the fourth time, I had everything more ou less setted up the way I wanted. Had some commonplace apps -- like WhatsApp -- installed, some UI features customized. At this point, I tought "Uff... Now it's all done".
However, it wasn't. Actually, I'm running into a bizarre problem with sleep mode, a few time after being locked. When my phone enters it, it won't exit. To make things a bit more clear: it dies, and in a way that's necessary remove battery and put it back on to turn it on again.
I'd check syslog and dmesg, but I don't know where are them at the Android filesystem (in fact, I haven't used *nix in a couple of years). So, I'm relying to my dear colleagues of these forums, if they have a clue on what's going on.
I'm using FXP330 ROM (http://forum.xda-developers.com/showthread.php?t=2584956).
Thank you very much!
