The following are the steps I have followed to flash the ROM with Mito scatter file, so I got 233MB. But still this is not enough for me, so I modded the int2ext script, so upon reboot, the script will move all system related dalvik-cache to internal storage for speed. Pre-requisites: 1. SD card partitioned. I got 3GB, it is your choice. 2. Micromax A75 I have installed 104 apps and still stable. But make sure that you have rebooted after installing 10-20 apps, so that the dalvik-cache will be linked to the external card for user apps. Otherwise, it will eat the internal storage. Steps: 1. Download this package and flash with SP_Flash_Tool_exe_v2.1121.01 which will give you 233MB internal storage. This may be good, but some of the apps missing as I would like to include everything which was in JetModv3.0. So, proceed to step 2. a. in SP tool, don't tick the 'PRELOADER'. b. Click 'Download' c. Connect your switched-off mobile via USB. d. Wait for few minutes till it get flashed. 2. Download this zip file and keep it in your SD card. 3. Power off your mobile, and wait for few seconds, and press volume-up and power button. 4. Using CWM recovery select install zip from sd card option and select the above zip file and wait for few seconds. 5. Select reboot in CWM recovery. That's it.
