Micromax Unite 2 A106 updated to Lollipop version and no network or sim detected Using Micromax Unite 2 A106, updated to latest version of lollipop, after finalization and restarting my phone is not able to detect any SIM/network. Also no display of selection of Mobile network is displayed in the Settings. 

If I try to dial any number the msg "Please close the airplane mode" is displayed. I tried reverting back to old version, removing the battery for 5-10 min, replaced another SIM network, but no change in the problem
me and my sis using this phone for almost 10 months...
First my sis upgraded her phone by downloading the official fota upgrade file from her phone and installed it. She also got same network issue.
Then I went to nearest service center and ask them about that issue and they had told me not to install by your own because it will delete the IMEI registration.
Then i had upgraded mine and my sister's phone to lollipop 5.0 in nearest service center.
Hope your problem will be resolved soon...
