Sorry but 10% is pretty much a guarantee of abs, if you don't have abs then every other part of your body should be looking VERY lean.
And no I will not trust you when you say you have done everything. You've only been at this for 2 years, you're still learning. Doing and trying everything just makes you sound like one of the obese ladies who "try" diets for a week and then give up or swap.
I'm not trying to hate. Just gotta realize this is a marathon, not a sprint. No one has complete knowledge after 2 years or even 10 years.
I would rather see every person here who is genuinely interested in any type of body building to be referred to
http://forum.bodybuilding.com for solid information. No hate to sythe but this forum is comprised primarily of guys aged 12-25 who's main focus is video games. When you first start out at bodybuilding you will believe almost anything you hear/read and I just don't think this is the correct forum for people to get their information from.
