How do I use lucky patcher without rooting the phone?

Yes.. you can use it without rooting your phone also...only the difference is that if your phone is rooted it can make the required changes in the installed app but if it isn't rooted then you have to first generate a new patched apk using lucky patcher then uninstall the installed version and the install the patched verison....Then it will surely work .. tested myself.

Someone requested me to describe the whole process.Here is how we do it.
1. First download Lucky Patcher
2.Install it in your phone.
3.Open the app.you will see something like this.

4.Click on the app you want to modify.Like i selected hill climb racing

5.Click on "Open menu of patches"

6.Now click on "create modified apk"

7.If custom patch is available click on it.If not click on"Apk rebuilded for InApp and LVL emulation".Here I am clicking on "Apk rebuilded for InApp and LVL emulation".

8.Click on "Rebuild The App" & wait some time

9.If it shows patch pattern success.Then there are chances if it shows all failed means there are no chances of you cracking the app.Here we got patch pattern success.
