I upgraded my Micromax A120 to rainbow and then to cyanogen mod. the cell network stopped working. then i went back to stock firmware but the cell network is still not working. i have tried using both one and two sims. i have tried waiting for 10 minutes after booting for the network to come but nothing. the network is in India. Please help.
I guess you have lost your IMEI... try *#06# to check whether you have a valid IMEI or not...
Thanks. i used mtk droid tools for changing the imei and it fixed the problem.
