(adsbygoogle = window.adsbygoogle || []).push({}); So yes this basically explains how to do it. This is if you want to open a shop like the Trophy Shops for PS3.. I will explain step by step!
What you need:
-You will need an existing Xbox Live Account(You're client account)
-You will have to recover the account on you're Console.
-Now you don't have to sign him out cause you will play offline after you recover that means you will just remove the Internet Cable or something that won't let you're console connect to internet.
-After you did the achivements you can go online and they will be synced,voilla that's all enjoy
This worked for me so yeah it will work and it's kindda easy to do
Also can anybody else try these and then post here if it worked for you?

Or Just use the hack to get achievements, you dont get reset these days haha

You don't get reset you are right you get banned for THIS thing
