GALAXY S2 Network problem (Flight mode switching)ONLY ROOTED DEVICE

Hello Friendz,
Few dayz back my galaxy s2 kept on switching to fight mode if ur having the same problem then follow the steps below
1. I have rooted phone so if ur phone is not rooted den don worry just go to service center(for noobs who have not yet rooted).
2.I was using CrisKelo Rom for galaxy S2 in which the problem occured.
3.FOUND NO HELP on interenet, they just stated problem was due to APN(access point name) settings not installed when i went in Settings>Wireless and N/W>Mobile Networks>APN.... i found out that my APN setting were actually missing.
4.I tried entering new APN setting MANUALLY...... TRUST me don waste ur time doin so.... i have wasted a lot..
5. Download a new ROM for galaxy s2... i downloaded OMEGA 3.0 which i found was as good as Criskelo.
THE MAIN PART STARTS HERE
before installing the new ROM
6.Format from ClockWorkRecoveryMode 1)SYSTEM 2) Cache 3)Wipe cache partition 4) Dalvic CACHE(Omega ROM will do all these steps automatically...:-))
7.install ur new ROM n njoi...
NOTE:- RESTORING ur phone wont solve ur problem... so act as fast as you can..
Any help drop me a mail on samgen1987@gmail.com
