HOW TO INCREASE PRIMARY PARTITION (INTERNAL STORAGE) ON AN MTK ANDROID

So you are looking at the specifications of your phone and see 8GB internal memory. You then slot in your 8GB memory and expect to have 16GB in all, only for your internal memory to show 2GB! Have you been scammed? No. Where then did the 6GB go? That's the underlined question behind the tweak in this tutorial.
How the 8GB (2GB and 6GB) in question is shared is decided by two files (EBR1 and EBR2) . The 2GB in this case, is the internal storage (where apps will get installed to) while the 6GB is the phone storage (acts as memory card when you don't have one). Once a memory card is inserted, the phone storage becomes dormant, what a waste!
Wouldn't it be nice to use 7.5GB for internal storage and 0.5GB for phone storage? Let's take a look at how you can do this by tweaking the EBR 1 and EBR2 files.
