On the MTK6589 phones they only have 1GB so I can't fit the new Color 2 OS(1.3GB approx.).
So I had to make it bigger to 2.5GB for system.
This where the rom goes the rest is used how you want.
On my phone I use the EBR1 together with EBR2 to re-write the memory.
None of my apps are on my sdcard, I could if I wanted to but I have no need to.
I'm waiting for the flash tool for the Find 7 to be released then a guy in a Chinese forum will do the rest.
This is his site

And this is the same OS as the Find 7 will use but for my crappy phone
