How to solve this... Not showing network
Go to settings>system>reset options>reset WiFi,mobile & bluetooth>reset settings for IDEA.
See if it helps.
If not, try re-insert your SIM card.
am also facing the same issue, it has nothing to do with idea as mine is Airtel! this software update has some glitch which is restricting our sim to fetch the signal , this happens whenever we switch it off and restart the device!
