HOW TO INCREASE YOUR INTERNAL MEMORY PARTITION ON YOUR MTK6577 PHONES

Most MTK6577 / MT6577 are advertised with having 4Gb of ROM. Actually it is 4GB of total memory space. This 4GB is shared between the main Android OS partition, the main internal memory where apps are installed and the phone storage.

The main internal memory is almost always configured at 503mb and is really too small for installing many apps and will fill up quickly. The phone storage partition is configured to be about 2GB for web downloads, photos and videos plus some space used for cache. Total space is slightly over 2.5GB.

Although the MTK657x phones have the option to install the apps into the sdcard, some of us don't like it as we want the option to change sdcards anytime.

There is an app on XDA forum which I have download and put it on my 4shared account for you guys to download. This app gives you the choice of changing that smallish 503mb to the whole 2.5GB leaving about 80mb for Phone Storage space. We can then use an sdcard to add extra storage space.
Why the phone producers do this is because the low end users can use the phone without adding a sdcard.
This app gives you the option to change your internal memory to 1gb, 2gb, 2.5gb or even 3gb if you have an 8gb phone.

But before you download and use this app, you need to be
1) ROOTED
2) HAVE CWM recovery installed
2) BACKED UP using CWM recovery.

I made a mistake and the phone refused to boot. You might also want to do this on a new phone because you have to factory reset your phone. If you fulfill the 3 conditions, go ahead and install the app. You will have to check 'install from unknown sources' in settings.
When you run the app, you can choose 1gb or 2gb or 2.5gb. Don't select 3gb unless you have a 8gb ROM phone and above. After you select your size preference, select 'boot into recovery' and the phone will reboot and send you into CWM recovery and you will need to Factory Reset or data wipe.
WARNING: DO NOT DO ANY OTHER WIPES LIKE WIPE CACHE AND WIPE DALVIK CACHE! This will cause your phone to hang during booting up. DO ONLY "WIPE DATA/FACTORY RESET" in CWM recovery and nothing else. Do not factory reset from your Android settings menu or your phone will go into a boot loop. I repeat again, do your factory reset only in cwm recovery menu. Use at your own risk.
