Hello Experts,
I am using Galaxy S duos(GT S7562). I was checking the Service Mode utility and doing research on 850 3G frequency for Latin Countries . selecting band selection on service mode suddenly , my network has disconnected(Wifi is working though) . Even the Network selection ( APN etc) have been greyed out .
I see the baseband version and IMEI number and network types shows unknown .
any suggestions ?
millions of thanks in advance
Hi frnds.. i had accidently set preferred network type to unknown by going in secret setting by using the code *#*#4636#*#* in my Micromax A54 and now my real imei number is changed into 00000000. My mobile is not recognizing any sim and on notification bar it says ''searching for service''. I am not able to reset previous setting i.e. unknown to gsm auto(prl) or gsm only or wcdma only. Please help me how can i resolve my problem.
Your help will be appreciated. thnx in advance..

I looking code Service Mode.
Thank advance.
Do this
Config>More Settings>Mobile networks.
In network mode select WCDMA Only for 3G and GSM Only for 2g.
Note: If you are using both sim cards only one sim can be set to WCDMA Only Mode.
