This problem raised When I flashed my lenovo s850 with custom rom when the flashing is done it worked but when I inserted my sims it showed me invalid imei then I typed *#06# it showed me invalid imei, ihav googled it & fixed my WiFi nvram error & successful with imei.zip method and pasted my imei numbers but same problem arises that no service when I inserted my sim & serial number also gone, it is showing sn:0000000, I have even showed in lenovo service center but they said it will take up to 20-30 days to return from factory.. Any suggestions to solve my problem?
Thank you.
