P.S. Why it open source for now?:
1. Now i don't have any MTK device and waiting for release MT6595...
2. I want to add making flashtool images without device, but i don't know how to do it... (looks like with linux you can create ext4 image... image size pick up from scatter, perms from updater-scripd, or just RW-R--R--)
