Sorry, did not understood your wording (can be an effect that I grown in different environment what resulted with other than yours standards and wording, apologies for that).
Did you mean, if it was really a reason to be sarcastic, while seeing the totally rubbish post, asking the @op to perform nonsense, useless and irrelevant in his situation actions because its author was not able to read the problem with understanding?
If so, the answer is: yes, indeed, it was a need to be sarcastic. Maybe the author would stop himself from posting nonsenses in the future.

Default Solved:Hex Editor Route

1- Flashed Stock android- adonis.pit & I9500XXUEMK9_I9500ODDEMK9_I9500DDUEMK9_HOME.tar

2- Rooted using CF-Auto-Root-ja3g-ja3gxx-gti9500.tar

3- Installed TWRP Recovery using goo

4- Downloaded Hxd (Windows Hex editor- Freeware)

5- Using ES Explorer (Root Mode) copied EFS folder to Windows and started opening all files-

Made following changes-

Change 1: In nv_data.bin change the addresses to this-

00188000: FF FF FF FF 4D 50 20 30 2E 38 30 30 00 00 00 49
00188010: 4E 55 00 00 00 00 47 54 2D 49 39 35 30 30 5A 4B
00188020: 41 49 4E 55 00 00 00 00 00 00 FF FF FF FF FF FF

This reads as - MP 0.800...INU....GT-I9500ZKAINU......

Change 2: efs\FactoryApp\ serial_no

Put the serial no in hex and changed permission to system and removed write access from system. After reboot it reverted to zero so made it read only for system (changed permissions from with in ES file manager)

Rebooted and it worked

I know.. I am lucky to get it back working.. have made 4 backups from dropbox to google drive now

You have the IMEI at under battery spot, so get the number than change the IMEi with IMEi Changer.

Take a look on google for a app for this.
Or with Notepad + ADB
