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.

Hi bigiliv

Follow this steps

1. Install orignal firmware of samsung.

( after installing orignal firmware you can get imei back automatic.)

If 1st step not work then follow step 2 n step 3.

2. Root your mobile

3. go to nearrst samsung service center and ask them to change your imei back to orignal imei.

How was it fixed? Please tell in detail.

1. Did you take your phone to the Service Centre and they fixed it? If yes, which service centre did you go to? (location)?

Or

2. did you get your IMEI back by flashing original firmware? By original you mean which firmware? Pls give the BUILD NUMBER of the original and from where did you get it?
