  • Followed instructions on a T-Mobile SM-n9005. Boots fine but I can’t get passed the setup wizard. It stops working after the CyanogenMod account screen. I tried logging in, not logging in, not installing Gapps, I went back and reinstalled making sure to clear all caches. Can’t figure out what’s wrong. I was able to trick the phone by long pressing the home button. So I can search for apps and use them But I have no home screen because I can’t complete the wizard. Any suggestions?

    • I have the same problem, but i find a way. So, follow these steps:

      1. Between the Steps 8 and 9, install only the CM 12.1 ROM – DON’T INSTALL THE GAPPS NOW.
      2. Reboot your device and complete the setup wizard. At that step, your fone will be in perfectly functioning, but not with the Google Apps, so, follow the step number 3.
      3. Reboot into Recovery Mode and proceed to install GAPPS. So, do a wipe cache and reboot. Install the SU.
      4. Voilá! Your phone will be perfectly working!

      Ps.: my english is not perfect because i’m not north american or anything like this (i’m brazilian). I learned your language only with music and movies. So, if i committed grammar mistakes, my apologies.

  • Hi,
    I installed CYANOGEN 12.1 on a galaxy note 3 dual sim ( SM-9002)
    but it’s not stable …
    A lot of problems, the smartphone is very slow, specially when you are using the keyboard.
    both network disappeared and are not well managed.
    BTW, thank for the work

  • I installed this version at my N9002. But here is the problem.

    The version of the topic not worked very well. My phone is the dual-sim version (China N9002) and the ROM only work with the SIM1. The SIM2 is not recognized by the SO.

    Ideas?
