[Galaxy S III General] oyeniyib:
Dear All,

I write to inform you that i finally solved my GT-I9300 'Not Registered on Network' problem. I decided to make this official announcement so as to assure others, most especially those who have tried almost all the tricks and steps found on this and other forum on the subject that all hope is not lost.

May be if i shed more lights on the problem which i encountered, and i suppose many other people, you will understand me very well. First, i did the upgrade through Samsung Kies and after the phone rebooted, it lost link to network. I called Samsung and chatted online with the Customer Service, i was asked to send the phone to South Africa where i bought it. I called South Africa and also chatted but they could not understand let alone solve the problem. I headed to XDA and other forum to find solution, I tried all versions of ARIZA Patch, none work. I tried all modified ROM, yet no solution. At one point, the problem became complex. The phone moved from not registering on network to 'Factory Mode'. I followed many other steps, but could not get past restoring it back to User mode. I gave up after a month and bought another phone.

My son shocked me last Friday when he said that it will be his first time of seeing me accepting that some problems cannot be solved. I mused over it and told myself that i will rather destroyed the phone totally than giving him the impression that i cannot solve the problem.

I got out my two computers - Mac and PC and reformatted them all. Installed ODIN and downloaded a 4.3 Stock ROM. I then began searching everywhere for any clue as to what went wrong with the phone. My research is simple; the PHONE could not register simply because the IMEI and Serial Number were wrong. My IMEI and S/N moved from 0000 to unknown. After reinstalling through KIES, it came back from unknown to another wrong numbers.

I finally decided to go inside the phone by activating everything on ODIN and see if i can get the wrong EFS on the phone wiped away and left empty. I repartitioned, wipe EFS, etc. and the only thing the phone did was to move from unknown to another incorrect IMEI and Serial.

Finally, i read on a post that the problem is simply software, so i began searching if it is possible to repartitioned the phone completely and turn it into a toy. I recalled that about ten years ago, i successfully installed Nokia OS on Blackberry through a poorly concerted code designed by a friend. In so far i still have the code, I thought that i could do same with my GT-I9300. It won't work, sadly. But in the process of doing so, i realized that using SRS, i can do so comfortably. With this 20 USD software, i gained control of the internal organs of my phone and started out by wiping out the EFS first and with my EFS Backup, i re-wrote it back on the phone. That done, i expected the phone to work, but sadly it refused to register on network.

Not ready to give up, i went further to see what other options are available to me. I realized that i can actually re-wrote my IMEI and Serial number back to the phone. I tried it and after about an hour and almost three attempt, T-MOBILE surfaced on my phone and the GT-I9300 came back to life.

Altogether, i spent two unbroken days reading and reading and applying one step after another, one procedure after another till i finally got the phone back.

SRS can not only do this, but can take back your contract and locked phone from those shylock and give you your phone. It go inside your phone and show you all the codes that locked you to a particular network, etc. It can remove those useless codes that make your phone patented to a particular country and give you an international version. It can also turn your international version to a local one, if you so desire.

I do not know who designed this software, i however testify to its immense ability to safe you from Samsung's irresponsibility.

I am open to helping others and answering questions on GT-I9300.

I have since been enjoying my phone.
