[Q] Mobile network not available (samsung galaxy s2) help

---

hello there,

IF YOU AQRE GETTING ERROR MESSAGE == "mobile network not available"

Ok here is steps again for you.

1. i downloadeD orignal samsung firmware of my country from www.samfirmware.com

2. Then i flashed it via odin.

3.then i rooted my phone. you can see old post about how to root. thats easy.

4. then i went to my samsung custumer service center. he was my friend. just switch your mobile On n connect it to there pc. he opened a software named SAMSUNG 3G TOOL. n there i see option REPAIR IMEI. he just clicked in it. then i typed my orignal Imei and pressed Ok.
And it done in 10 seconds.. n phone got restarted automatic.

I seen my imei changed n got my network back . i was happy.


Note#
cynogenmod 7 & cynogenmod 9 both are crap for samsung galaxy s2.
Because there is no android market and network on/off instaly.. u cannot make call if u install that. so beter use orignal samsung firmware in s2.

Hope this msg help you. gud luck.
