Google play crash with CM12 on OPO

Hi all,
I updated my OPO to CM12 and the google play services can't be updated leading to the notorius battery drain plus several other issues.
It's all stock, less than 1 month old unit, what can I do?
The previous version, CM11 was great, the current YNG1TAS17L is creating only problems.
Please help.

Nexus 5 sudden crash

Running kitkat, battery recently replaced. all good for a month.

Yesterday the phone suddenly switched off , i switched it on again and the battery had jumped down about 40%.
It crashed again but then remained stable for the rest of the day.

Tonight (at 50% battery remaining) i got a sudden warning "6% battery remaining" and it crashed again, i switched on again and the battery went back to normal , around 40%, stable since.

Any ideas or is the phone on the way out ?

[HELP] System Crash

I have a 32GB Nexus 5. Yesterday, I made a backup, then attempted to flash this stereo mod. After reboot, the launcher stopped. I attempted to go into the settings via recent apps menu, and SystemUI crashed. I flashed the stock mixer_paths.xml file, rebooted, same thing.

I restored my backup, and oddly enough, it still didn't work. I followed this guide to flash the factory image of LP, and even after the factory image, it still crashed. I installed the task manager I normally use, noticed that it didn't show any processes. Literally says 0 Processes, 20 services.

What could be the issue? Any way to fix?

Google Play Crash

everytime i open my google play store it crashes, syncing stops and tells me there was an error and it will try again later, when i download stuff on the google chrome app, it says "No sd card"
I have Viper One 8.0.0.0
i tried uninstalling the play store and reinstalling, i tried clearing cache and data, i tried editing the hosts file in /sdcard/etc/ , i tried factory reset, i flashed different roms, no luck at all. i tried repairing and clearing the data, system and cache partition in TWRP recovery. i assume all these issues above are connected, any advice? thanks in advanced.

*EDIT*

also snapchat has the alert "put in a sd card to watch videos" but i have a htc one m7? theres no sd card spot

Multiple games crash?

I have had more than one game crash on this phone. One of them worked fine on my Samsung Galaxy s4 so I'm not sure why it would crash on this phone. My phone is rooted and I'm on 5.1. My model is H812. I think this phone is supposed to be pretty powerful so it should be capable of running them.
