muhsin Hello,
You may must carefully pay attention to the backcase of the phone, there are different serial number for redmi 2, especially for last two digit of this serial number, which are using different version of baseband firmware.
The baseband version must match with this serial number. This is last digit you must know : xxx11, 12, 13, 16, 17, 18, 21.
Many web and forum share this kind of baseband firmware, you can start googling to get correct baseband version.
