To anyone who might be interested, I have fixed the problem.
i hv tried evrything but none is useful as below.
its to simple. no more headache at all
I had to root the phone, and install Busybox. Then I installed an app called GSII_Repair. In the app, theres an option to ‘Mount EFS on RW’. I did this, and after rebooting, it works! Back on the network, and now the IMEI number can be viewed again!
I tried this but no luck. I still don’t have my imei back. Is there anything else i can do? Or is there something else you’re supposed to do that’s not written down here plainly?
