Some versions of the Nokia 1616-2 firmware (very specific revisions, usually engineering samples) have a hidden menu. You access it via *#3646633# or *#*#3646633#*#* (MTK engineering code). If this works on your device, you navigate to:
Connectivity -> CDS Information -> Radio Information -> Phone 1
Here, you type AT+EGMR=1,7,"NEW_IMEI_HERE".
This is an AT command (Hayes command set). However, on 99% of Nokia 1616-2 retail units, this command returns an "Error" because the NV-RAM is locked.
