Help Changing Internal Memory with External Memory on LG F70

[jasu99]

So I want to change the tiny 4GB internal memory with my new 32GB external SD card. I have successfully rooted my phone (also checked with Root Checker). I would like to know if anyone has a method to doing this that will work for this phone, the LG F70.
I have searched for ways to do this but they just havent worked out for me. Do they really not work or am I doing something wrong?
Any help is appreciated
