[Completed] Have signal but not registered on network

I have Samsung Galaxy S3 GT-I9300. When the google drive app was downloading from google play, my phone went off due to poor battery. Later when I tried to turn it ON, it has been getting stuck in the boot. So I decided to reinstall my custom ROM. Being busy with my baby, toddler, household chores and job, I gave it to my brother to flash the ROM. After a while, I noticed that my sim was bricked.
It says "Emergency Calls Only", has fake IMEI but working signal.
We did not backup the efs. I tried searching all the methods like modem installation, CSC, baseband verions, IMEI re-write, Kies Upgrade and Initialization, other people's efs restore, etc. But the problem is unchanged. Some of the followed method might have failed for not having proper knowledge like IMEI re-write tool works on specified chipset, etc.
What we noticed is that using different baseband version toggles from having network signal or no signal.
Kies shows more than four firmware versions and no other details like CSC, etc.
How do I clean up all these especially to have SIM working on my phone?
I appreciate you assistance to be brief and clear to understand steps than sending links. Because my time is stress-fully short.

Hi !
There is some confusing info in your post
What do you mean with it has fake IMEI " ? Have you changed it ?
You say that you have a working SIM on certain basebands , is this happening on a custom rom or stock ?
Have you tried to flash a stock firmware as I see that you tried to flash "your custom rom " ?
Cheers !

First of all, thank you for your response and interest to assist.
My mobile's IMEI is shown as 004999010640000 which is not original. Can you help me to change it to correct IMEI suitable for my Samsung S3 GT-i9300 chipset, if that helps in enabling sim to connect to a network? I think changing method only masks the IMEI?
I have tried flashing stock firmware and also Kies Upgrade and Initialization.
I have also changed baseband version installation on stock ROM too. I don't know which baseband is correct to keep.. for my country India or in the country where my mobile is manufactured, incase that's locking sim accessibility? Some baseband bought signal and detected the network operator name, but the message still says "Emergency Calls Only" and is unable to connect to a network.
I presume this problem arose when installing custom ROM from TWRP recovery and it messed up with efs partition?
I had successfully flashed custom ROM many times before without this problem. I think there's some next step to follow to bring back the working sim like I heard of installing modem. I did just try installing modem but same problem as my baseband is already bringing signal.
I had tested my phone from sim unlock app and found out that CSC is locked and it limited specified MCC and MNC numbers. Is this hindering connection to Indian mobile network? Or corrupt efs? Or missed to manually install something?

Bump.
