What firmware can we flash on what model??

[senter]

Hi,

I am beginner. I have W700i phone. Someone says, you can load w810i firmware on w700i.

My question is how can i know which firmwares are proper for which models? Is there a way to find out this.

Recently i bought K610i. Now, if i want to flash different model's firmware, what models' firmwares can i flash to it? Which are compatible.

Could someone answer me with clear details so that it will help me alot in understanding.

Thank you very much for your time.

Regards
Anil

Must have same platforms, same hardware - then it can.

For example K750 is DB2010 platform, W800 again is DB2010 and have same hardware.
K800 DB2020 -> K810 DB2020
K530 DB2020 -> W660 DB2020
