You're right, I didn't fully answer your question there are a bunch of SafeStrap threads out there and a few of them have the answers you're looking for, but not the one I linked to.
Since we have a locked bootloader we cannot flash things that aren't signed by Samsung. SafeStrap gets around this by redirecting everything to a different data partition. Unfortunately it can only do this after the kernel loads, and since there's no way to flash a different kernel you're stuck with the stock kernel on your phone. This is important.
You can only flash ROMs that work with the stock kernel on your phone. So since you are on MF3, you can only use ROMs that are based on 4.2.2 TouchWiz. If you're on MI2 then you can flash 4.3 TouchWiz-based ROMs. So you are very limited as to what you can flash.
As for not being able to get ROMs to work, you need to make sure you have enough free space when creating a ROM slot, 4-5 GB should be plenty. You cannot share apps or data between different ROM slots so be careful with your space. You should be able to get the GPE ROM to work, I'm using it right now. So completely delete your ROM slot 1 and recreate it. Then follow the steps exactly as they are written in the thread I linked to and make sure you flash the proper module files for your phone.
If you have any other questions, let me know.
