[Galaxy Grand Duos i9082 Android Development] KSKHH:
Your ROM might not be init.d script supported..

Then try this before above instruction

Download the zip_init.zip file on this thread and flash it.

Settings of Internal to External

1 > Open software go to settings and select option as in image and check boxes as shown

2 > Change the value from 179:49 to 179:9 and click ok

3 > On main screen check box if init.d enabled and click both "Internal to external" and "if init.d at boot "

Two things -

1) the stock version of this rom (unmodified) has 66 apps (that's what it says when optimising after doing a wipe cache/dalvik) and this rom has 140+,

what's the 70+ apps extra it's optimising in your version?

2) the rom is great but I really miss the bigger 4x app size buttons, 5x is just too small, can you provide a flashable zip file to make them 4x again (in size) for those of us who prefer that?

Thanks, keep up the great work ;)

However when I go to settings->applications the memory still shows that the device has only 800mb of usable memory (in the bar below the list of apps. Is something wrong?
