[Q] Flashed Stock Rom 4.3 via ODIN, can't make/receive calls topic

SOCIALIZE IT ⇨

Hello People

Again, I'm with problems with my S3 since the one time decided to test a custom ROM which turned out to screw my IMEI and got to it back working with BOX in repair service.

I n order to see if the BOX fix did actually solve my signal problem, it was suggested to me in a previous post that I flash the same stock rom via ODIN. Before that, I backed up current EFS as well.

Unfortunately, it seems the problem wasn't entirely solved. Same as before: both my IMEI and S/N are untouched (S/N does not coincide with S/N in the back of phone) and though it says I have a full signal, I'm not registered in network and i can't make or receive calls, sms, etc. Even though I restored the EFS folder, nothing happens.

I really wish not to go back to repair service again. What else can I do about this? Many thanks and excuse my rant. Hope I was thorough and clear on the problem. I also have a EFSv2_basebands_opt4.zip file I downloaded somewhere in xda . Would that help?

Many thanks.
