1. download suitable modem file for i9505 and i9500 from here:
[REF] GALAXY S4 (I9500/I9505) GSM / NON-HLOS… | Samsung Galaxy S 4 i9500, i9505, i9505G, i9506

2.write this file with CWM ( don't reboot device )

3.wipe data and factory reset and reboot

done now you successfully repaired your baseband
