I'm trying to figure out how to word this so here it goes:
The reason you aren't getting the replies you seem to want is that no one really knows what to tell you. No one is replying because no one has anything left to say. Almost all advice or suggestions you've been given have been brushed away as something that won't work or you want even more detailed, step by step instructions.
The issues with that is that step by step instructions, over the internet, to a dog we don't know are very difficult. Dog training is fluid, it changes depending on the dog, the handler, the environment, the wants, the skill level of all involved etc. Someone could give you the most detailed step by step instructions around but that doesn't guarantee anything will work, you still will probably have to tweak and adjust based on you and your dogs.
And that takes us to the other issue, you're asking for something that this forum just isn't going to supply. We are discussion based, we like to bounce ideas off of each other, ask for suggestions and have conversations. This forum isn't going to act as an instructional pamphlet and trying to force everyone on here to do that has just resulted in no one replying to your threads.
You've been given a lot of good advice on how to teach a drop, I would suggest rereading that thread and really trying some of the suggestions. Don't assume they won't work for your dog, try them, pay attention to what she's doing and adjust from there. Take a video or yourself and her during a training session and watch it after. You could even post that on here so that people can give better advice because they can see what and how you are training. Try Allie's advice and go to some real life classes with her, talk to a trainer in person who can watch and help you.
My last piece of advice is instead of trying to force and create topics like you've been doing, join into some of the existing topics. Talk on some of the other threads, add your experiences to other threads people have made.
Let us get to know you and your dog.
