I'm right now with Zaiben 10 and cmw 188.8.131.52.
When I try to flash a 4.x rom, I make a full wipe/factory reset, then I install the rom and finally the gapps. So far OK, but when I restart the mobile, don't boot, there's only a white screen and my phone goes off.
I don't know If I am doing something wrong, but I really appreciate If you can help me to finally install LegoRom or Nameless Rom.
Thanks in advance.
