Modify Samsung Firmware -- 2

Hello My name is sachy I have a feature phone from Samsung, model e1200y, running Spreadtrum chip (sc6530). This firmware is based on normal Spreadtrum firmware for sc6530 chip. The platform that used for build this firmware called MOCOR mmi. (similar to all Chinese Feature phones) We need someone who can modify this firmware. We no have any source code. We only have the closed firmware download below. We actually need adding Hebrew language to this firmware, and also maybe doing more some changes. More details if needed please contact me. I’m sending here link to the firmware that we are talking about. [login to view URL] Note: the resources of this firmware are stored in [login to view URL] in the rar that I sent.
