this is just another Lenovo S650 problem with simcard not detected, while the Imei Missing,
if it happened to you, you’re not the only one,
so wondering to try another method using MTK Droid Tool to write the IMEI but got few error which time is very limited to solve,
so we use the conventional method which backup and deleting the nvram folder.
