  1. 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?

          1. hi bro

          2. hey guys i have the same issue ,, cant get past the set up point .. CM setup wizard ??? how do i delete it ???

    1. 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.
