anyone know how to disable one of the sims?
I cant seem to figure it out, the changelog said that you should be able to disable either sim but i cant see how its supposed to be done?
Its not under "Msim Settings"
or is it something wrong with my update?
Can someone please check if its possible to disable sim?
Help me pls!
My ROM is now CM 12 5.0.2 . I installed the USB drivers, usb debugging is enable, factory and adb port selected, installed the updater tool and of course unpacked the rom, selected the unpacked rom directory and the mobile phone icon is always red. Anyone has any idea?
Thx!
I'm on this sofcie inagle stopped working three lower house keys back, etc.
nice rom
defently smoother from the 1.59
i followed the steps described in the OP and the phone works with a few problems
when ever i am trying to share a picture in whatsapp the app crashes
also a "Family Guy" game crashes after a few seconds
is it only happens to me?
any idea on how to fix this?
Installed it yesterday directly from 1.64 to 3.09. Installation although takes time, it is pretty smooth. Overall performance and looks is good.
- 4G works on both SIMS
- Icons and Text was initially looking big, changed it to 400DPI using a DPI update app and now looks perfect
- Dialer was taking more than 10 secs to load contextual numbers. Cleared the data from Nubia Contacts and issue resolved
- Yes, Youtube finally works
- UI is mostly like before and has only 4 columns of icons instead of 5, which is quite small for a 5.5 inch phone
- IR blaster works fine and camera app is improved as compared to 1.64
- Most of the important google apps work pretty well
- Lockscreen notification are very good
Issues:
- Dialer & Contacts uses YellowPages on the background. So, you get lot of unrelated number when you try to search for names. Anybody found a workarround for this ?
- Some of the apps still don't work like before. Viz Sygic, Weather Widgets etc
- Default browser is mostly chinese and acts little wierd

Hey there!
I have issues making use of the GPS. It doesn’t dix at all.
Someone have the same probem? Any solution ?
Thanks
Well, finally it works outside. Looks like the A-GPS is broken, like another person said before.
There was something to do with a ROM before, to obtain 4G. I’m going to try stuff.
Cheers
