Hello guys
This thread will show you how to fix your IMEI problems and get official status on your Galaxy S4 (GT-I9500)
Its working 100%


First root your device with CF-Auto-Root-ja3g-ja3gxx-gti9500
Reboot in DOWNLOAD MODE ( Volume Down + Home + Power )
Connect your phone to PC via USP cable
Run Odin3 > click PDA or AP > Choose this file (CF-Auto-Root-ja3g-ja3gxx-gti9500.tar.md5)
now click Start
Phone will reboot then its rooted

Second install TWRP Recovery
Reboot in DOWNLOAD MODE ( Volume Down + Home + Power )
Connect your phone to PC via USP cable
Run Odin3 > click PDA or AP > Choose this file (openrecovery-twrp-2.7.0.0-i9500.tar)
now click Start
Phone will reboot then you have TWRP Recovery installed

Third reboot in RECOVERY MODE ( Volume Up + Home + Power )
Tap Wipe > Format Data
Tap Wipe > Advance Wipe and select all EXCEPT External SD and USB Storage
Tap Reboot > Download Mode and flash Stock Firmware (must be same country)
Wait till finish and now you have Official status and original IMEI and receive OTA updates

If you don't know how to flash Stock Firmware this is how
Reboot in DOWNLOAD MODE ( Volume Down + Home + Power )
Connect your phone to PC via USP cable
Run Odin3 > click PDA or AP > Choose downloaded file .tar.md5
In my case its I9500XXUFNB4_I9500OJVFNC1_I9500XXUFNC1.tar.md5
now click Start
Phone will reboot

you should make wipe data from stock recovery
and your done.

I hope it will be useful for some people
