@Jorgen did you try recently with the ESP01? late last week I made some fixes/tweaks to it.
For the ESP12 it could be the same problem that @user55329 is having I guess. Does it seem to have a TX activity light like the ESP01 does? Does that flash at all at startup?
There's not much that can be different - you could try shorting out resistor R1 if you don't have any SMD resistors to hand...
