Well, these are more advanced techniques and can take time. I think as long as you keep trying, you'll end up succeeding. To be honest it sounds a lot like what even still happens to me. DEILD got me into SP twice but hasn't ever since. Using WILD I've never hit SP, I just enter straight into the dream (the times I get it to work d: ). So just keep trying. I know it can get boring just waiting, but don't treat SP like its required in order to get a lucid. The main focus should be getting the LD and not SP, even though SP can be fun sometimes too.
