Should I use this fix only on Android 4.1 and 4.3?
Do not try this on Archidroid 3.1.5 (Android 5.1.1)??

EDIT:
8. Choose GT-i9300 on the List & COM Port
It says "Card not found" (running OctoplusSamsung.exe), but application is running
I choose GT-I9300, COM port only COM5 available, I press Read Info button, and there is "Reading info, please wait..." and nothing happens

When I try to start Loader Octoplus Samsung.exe - nothing happens.

According to Windows Defender, unins000.exe has Virus/Win32/Sality.AT

After Flashing the EFS file you provided, I've lost my IMEI as well.
Of course the repair network option completed successfully. But it didn't fix the no network problem. It just created one more problem and my IMEI is now generic.
