Hello,
My first time posting here.
I got a used smasung s3 phone from someone.
After that i installed a new ROM , that was my first time Installing any ROM.
after installing, my S3 got network locked and asking for network code on start up. I searched forums, got different suggestion but nothing worked out, and i had to get it unlocked from some mobile repair shop.
Now i want to install some other ROM on my S3, i have concerns for same issue again.
My quries are,
1 : Will my S3 get locked after every new ROM install?
2 ; network lock code is based on ROM? i mean if i install a worldwide open ROM, it will not get locked? or network code is something different that ROM issues?
3 ; Can i take backup of my mobile in the case if after installing new ROM it gets locked, so that i can go back to revious status? Is it possible?
4 ; Is there any thing / folder to back up , so that after installing new ROM i can get my mobile unlocked?
5; i am reading about EFS thing, does it mean if i backup that folder, i can get my mobile unlocked for new installation
I knw these are v basic Questions, but i am searhing in forums to understand these things, can someoone please clear me or can point me to some thread where these issues are answered.
Thanx alot for help.
