[ZE601KL CN 1.16...] Is there any way to access playstore or chaneg Cn to WW yet?

Hi guys,
Firstly I want to say that I am new here and I' m really impressed by this forum.
Now to my Situation:
My grandmother brought a Zenfone 2 Laser from tinydeal, it was delivered with CN_1.16.40.1338 and therefore has no access to goole playstore.
I googled a while and tried to apply Gapps, manually installation (googleservcie, framework and store.apk) and method via mi appshop - none of them worked properly, playstore was installed but only a white screen appeared after starting the app.
On the other site I tried to switch to a custom rom:
- Cyageno 13 has the no speaker bug fpr ZE601KL
- http://forum.xda-developers.com/zen...om-stock-deodexed-pre-rooted-1-17-40-t3387731
won't install (yet) because of Error 7 (I assume the system partition is too small...)
Before I continue with my try and error does somebody know if there has been a suitable method for region change or woking playstore on a CN discovered yet?
Thanks in advace for sharing your knowledge

Root under Android 8.0.0

Hello All , Sorry for my english !
So I bought my Google Pixel C under Android 7.x.x , now running under android 8.0.0 . I have also a cable USB type C to USB . And a PC .
Now I'm looking for the root of my tab , I'm not particulary comfortable with the developpement in general but really motivate to learn .
I also search on internet but 100 % of tutorial are old now since android O . Could you please help me with that ? Thanks to tell me if this thread is totally inappropriate , if it's the case I'm sorry
Rooting oreo is the same general process as previous builds. Use TWRP 3.1.1-1 and supersu v2.82-sr3. I'd suggest leaning how to use fastboot rather than tool kits. Tool kits such as NRT by WugFresh are good but if you really want to learn learning how to use fastboot is best.

Help me to change blackshark 3s cn rom to global rom

Hi everyone member here.
I'm a black shack 3s user, I bought this device from my friend last month with china ROM installed.
I have questions, Where and how do I get and change from china ROM to global ROM?Because I have a problem with the china ROM on my cellphone, like one of them there is no notification from the whatsapp application so I have to open the application first then there is a message, and the next problem can't open email with gmail app.
But beyond that, my cellphone doesn't get updates and stops on JoyUI 12 20.08.08.
Do you guys have a solution ?
